PJ Masks is a Disney Junior cartoon that premiered on September 18, 2015. It is based on Les Pyjamasques, a series of French picture books created by Romuald Racioppo.

Connor, Greg and Amaya are three regular kids who lead normal lives during the day. But by night, they become superheroes known as Catboy, Gekko and Owlette, the PJ Masks, who protect their home town from the antics of nighttime villains.

As the show went on, more heroes and villains were gradually introduced. As of Season 6, the show is now known as PJ Masks: Power Heroes. Unfortunately, with the collapse of the France animation studio TeamTO and director Christian De Vita leaving the series after season 6, the show has gone on indefinite hiatus.

"TV Tropes, all shout hooray! Because in the night, we trope the day!":

• Acquired Situational Narcissism: Amaya falls into this in "Owlette the Winner," after scoring a lucky three-point shot in basketball. She starts to believe she is really that good and begins treating everything, including the mission she and her teammates are on, as a competition.
• Actor Allusion: In "Wacky Floats", Night Ninja (whose voice actor previously voiced Rubble in PAW Patrol) remarks that he's always wanted to be a salty sea dog.^note "Wacky Floats" aired roughly 5 months after Sea Patrol. Bonus points since he was talking to Romeo, whose voice actor also played a pup (Specifically Zuma) on the same show.
• Adaptational Badass: Early on in the picture book series, the main protagonists' book counterparts were limited to using hand-to-hand combat and were able to investigate villain activity by traveling on foot. The television series gives the characters new abilities such as super speed, super strength, vehicles, and even a superhero base.
  • The villains face this treatment as well. For example, Romeo's motive in the book series was to either capture dream-related entities or to demolish the main characters' school. This was changed to having him plan a general quest for world domination in the television series.
• Adaptational Diversity: In the picture book series, the book counterparts of the characters are mostly French, and some of the characters are named after mythologic figures (e.g. Connor/Catboy becoming Sacha/Yoyo). The TV adaptation changes the characters to be Americian, while receiving names of western superhero alter-egos and civilian names that fit more with their background. While the France setting remains unchanged in the television series, it adjusts the setting slightly to contain multiethnic North American elements.
• Adaptational Mundanity: Compared to the original book series, the show replaced the fantastical parts of the premise of the source material, associated with the themes of children's dreams and imagination, with contemporary superhero culture that gears more towards an older audience. These notably include the book series' premise focusing on overcoming children's fear of the dark and nightmares caused by supernatural beings derived from fairytales and story books, and the recurring theme of children's beliefs in magic and dreams such as the PJ Masks befriending a huge werewolf, the moon having a face, and the young heroes going up against supernatural villains like an evil version of The Sandman, a living snow statue, various monsters, and even the Egyptian deity Apophis (who would later be added to the television series as Pharaoh Boy).
• Adaptational Nationality: The characters go from French to Canadian.
• Adaptational Nice Guy: The villains from the picture book series are not afraid of using any lethal weapons against the heroes. This was toned down in the TV series, where they use weapons such as laser guns, moon bubbles and sticky splats to trap or disable the heroes without inflicting lethal or lasting harm on them.
• Adaptation Dye-Job: In the books, the main protagonists' costumes resembled those of plush costumes. In the show, the television counterparts of the main protagonists have their costumes redesigned to look more like real, traditional superhero costumes.
  • This particular aspect would shortly be incorporated into the book counterparts of the three main protagonists once the television series premiered, despite the fact they retain the animalistic bellies in lieu of their symbols.
• Adaptation Name Change:
  • Les Pyjamasques are renamed as the PJ Masks in the show.
  • Yoyo is renamed Catboy, Bibou is renamed Owlette, and Gluglu is renamed Gekko.
• Adaptation Personality Change: While Les Pyjamasques' TV counterparts, the PJ Masks, are always on the side of good in the TV series they're depicted as more mature rather than mischievous.
• Adapted Out: The picture books featured quite a few supporting characters have yet to appear in the tv-show. These include Les Mascrapules (three kids with superpowers based on a rat, fly and worm) and Energuman (an adult superhero similar to Thor).
• A.I. Is a Crapshoot:
  • In "Owlette and the Flash Flip Trip", after a fall, Romeo's robot thinks Owlette is his master and Romeo is the enemy, making this one of those rare times where this trope actually helps the heroes, instead of making things worse.
  • In a more traditional example, "Catboy and Gekko's Robot Rampage" has Romeo building a new robot sidekick for himself after the old one leaves him, which malfunctions, kidnaps him and decides to Take Over the World.
  • In "Lost in Space", Romeo decides to boost the intelligence of the central computer of his Flying Factory so it can help him think of a plan to defeat the PJ's. The Computer promptly becomes sentient and takes over the factory, imprisoning Romeo.
• All Animals Are Dogs: Gekko's pet lizard Lionel loves to play fetch. His PJ Rider, Power Lizard, acts more or less like an oversized puppy.
• Alliterative Name: In the Italian Dub all three PJ Masks have G names in the form of Gattoboy, Gufetta, and Geco.
• All Your Base Are Belong to Us: All Nighttime villains have at multiple times targeted the PJ Masks HQ in an attempt to either conquer or destroy it, or to steal something from it for their next scheme. With varying degrees of success in the case of the latter two (best case scenario, they get stopped before ever setting foot inside, worst case they succeed and the heroes have to deal with the fallout).
• Anachronic Order: Happens in season 2 and 6.
  • The episodes "PJ Robot/PJ Power Up" come after "Wacky Floats/Romeo's Disguise" by airdate, but chronologically they are set before "Wacky Floats/Romeo's Disguise." This is proven by the fact that the former two introduce the PJ Masks' new Robot Buddy and powers, which were already present in the latter two.
  • The episode "The Christmas Ninjalinos" aired after "Gloop the Third" and "Wolfy Riders/Gekko Muscles In", but a line from "Gekko Muscles In" reveals that the first-mentioned episode takes place before the other mentioned episodes.
  • It happens again with the episode "May the Best Power Win," which is set immediately after the PJ Masks got their new powers (they are seen practicing with them, and Catboy mentions this is the first time they use their new powers against Romeo), so this episode is chronologically set before "Wacky Floats/Romeo's Disguise" as well.
  • Similarly, the short "PJ Racing" is set after the events of the Season 3 episode "Take Romeo Off the Road", despite having aired before it, due to the latter showing the origins of the PJ Seeker.
• Animals Lack Attributes: Since this is a kids show, none of the animals are depicted with visible genitalia. It's especially noticeable with the much larger PJ Riders.
• Animal Superhero: Staring with the Season 5 premiere "Ninja Power Up," an owl, the recurring stray cat that's seen on and off since Season 1, and Greg's pet lizard Lionel frequently support Owlette, Catboy and Gekko respectively. In "Owly Tricks," the owl and cat are revealed to be named Owly and, well, Cat.
• Animal-Themed Superbeing: The PJ Masks.
• Animation Bump: The animation is noticeably smoother in Season 2 onwards.
  • In addition, in Season 3, the animators added more animations to the Ninjalinos and Luna Moths by allowing them to move their chins when speaking.
  • Season 6/Power Heroes likewise shows a bump in animation quality. Characters are shown being a lot more dynamically fluid and expressive in their emotions and movement/actions.
• Animorphism: In “Robot's Pet Cat”, Romeo's latest gadget turns Catboy into an actual cat.
• Anti-Sneeze Finger: In the episode Gekko's Stay-at-Home Sneezes, Amaya does this to Greg at the start of the story. It works.
• Artistic License – Biology:
  • The episode “Easter Wolfies” featured the titular villains attempting to steal and eat chocolate eggs, and Howler at one point eats a raw onion. If the Wolfies had been actual dogs, they would be much worse off since chocolate and onions are highly toxic to canines. Even if it didn't kill them outright, the chocolate would have given them severe gastrointestinal issues; and in Howler’s case, the onion would have made him severely anemic.
  • Octobella is an octopus/cecaelia who lives in a moat (a freshwater body). Octopi are saltwater creatures and there are no freshwater species; if one were placed in a tank filled with fresh water, it would result in death.
• Attack of the 50-Foot Whatever: Gekko accidentally grows to a gigantic size with Romeo's super-sizer, as well Luna Girl's moths and one pigeon in the episode "Super-Sized Gekko".
• Attention Deficit... Ooh, Shiny!: Gekko's main flaw in the episode "Slowpoke Gekko".
• Badass Adorable: The PJ Masks/Power Heroes. It kind of goes with the territory of them being Kid Heroes.
• Bad Boss: A recurring theme with the villains is their mistreatment of their respective minions.
  • Night Ninja constantly makes his Ninjalinos do all the work, rarely showing any appreciation or gratitude in return. Though to be fair, some of his plans do tend to fail because of them.
  • Luna Girl frequently criticizes her moths and often threatens to replace them (and has done so on a few occasions). The entire "Ninja Moths" episode focuses on this.
  • Romeo is frequently annoyed by his robots' messing things up.
  • Owlette ends up being one in "Owlette and the Owletteenies." The Ninjalinos turn on Night Ninja because of his constantly mistreating them, and turn to Owlette to lead them instead. Owlette ends up just as bossy and overbearing toward them that they eventually decide they like Night Ninja better and go back to him, though Owlette does tries to apologize after she learns her lesson.
  • Octobella also falls into this, as in "Magnet in the Moat," she is regularly seen teasing Percival, much to his annoyance.
• Bigger on the Inside: HQ. On the outside it seems just big enough to house the PJ Masks' vehicles, but nothing more. On the inside however, each compartment can easily hold the corresponding vehicle with lots of room to spare.
• Birthday Episode:
  • "Catboy and the Great Birthday Cake Rescue" is one for Greg. His age is never mentioned however.
  • The short "Moon Rocked" resolves around Luna Girl's birthday (again, with no age mentioned).
  • Greg's birthday is celebrated again in "To the Moon and Back".
  • In a take that actually reveals the character's age, the episode aptly titled "An Yu's Birthday" takes place during An Yu's birthday, where she mentions she's turned 2001 years old (which in dragon years is the same approximate Vague Age equivalent of six that the rest of the cast shares).
• "Both Sides Have a Point" Remark: In "Gloop the Third", the team acknowledges that they should have taken things more seriously about the strange asteroid (really a Gloopet pod) instead of joking around about its weird noises and smell, while Newton concedes that there's nothing wrong with being funny and that he should have listened when they tried to tell him about what they had discovered.
• Bowdlerise: The Season 1 episode "Catboy and the Shrinker" during which the heroes drive around Romeo and Night Ninja in circles to make them dizzy, Romeo calls Night Ninja a dizzy ninja, while Night Ninja calls Romeo a stumbling buffoon. This line was muted when the episode was on Netflix, deeming it too insulting/rude for its target audience; reruns, DVDs, digital releases, and Disney+ however, retained the line.
• Bullying a Dragon: The villains often mock and insult the PJ Masks, despite knowing full well that they are superpowered kids.
• Catchphrase:
  • "PJ Masks/Power Heroes, we're on our way, into the night to save the day!"
  • "It's time to be a hero!"
  • "PJ Masks all shout hooray, because in the night, we saved the day!"
  • Catboy's "By my cat's whiskers!"
  • Owlette's "Fluttering Feathers!"
  • Gekko has several, but his most notable ones are "Gasping Gekkos!", "Leaping Lizards!", and "Slithering Serpents!"
  • In season 2 onward, Robot (Romeo's robot who appears the most often) frequently began to say, "Oh no!".
  • Then there is Armadylan's "Armadylan Style!"
  • Newton's "By my stars!"
  • Ice Cub has "Shuddering Snowflakes!" and "Infinite Icebergs!".
  • Lilyfay's are "Atomic Asteroids!" and "Cosmic Zing Bing!"
  • Bastet has "Growling Pyramids!" and "By the Mummies of Meow!"
• Christmas Episode: Three: Season 1's "Gekko Saves Christmas", Season 3's "The PJ Masks Save Christmas", and Season 6's/Power Heroes' "The Christmas Ninjalinos". The latter two are also two-parters that takes up both parts of the episode.
• City of Adventure: The nameless city of the PJ Mask Power Heroes has no shortage of adventure; there are various villains roaming the streets at night, multiple other-dimensional portals, including one hidden behind a wall in an alleyway that leads to a mystical mountain, another to what is implied to be the afterlife in a sphinx statue in the museum, and yet another that leads to a snowscape with a temple cavern dedicated to ice power, various relics and artifacts hidden in the city, and caves underneath it that contain even more relics, plus more artifacts still contained in the realms beyond the different portals.
• Clothes Make the Superman: The PJ Masks' powers come from their pajamas. This includes some of the heroes who would later become the Power Heroes of Season 6, including Armadylan (implied), Newton Star (visually), and Ice Cub (explicitly)
• Colony Drop: In "Owlette's Luna Trouble", Romeo steals Luna Girls' magnet, amplifies its power, and uses it to try and make the moon crash on HQ.
• Compressed Vice: Several episodes will have characters reveal a flaw that they need to overcome in order to be able save the day, even if they previously never had such problems in the first place, often for the sake of delivering the episode's moral.
• Cool Airship: Owlette's vehicle, the Owl-Glider. The PJ Jet, the combination of the PJ Masks' original three vehicles, also qualifies.
• Cool Car: Catboy's vehicle, the Cat-Car. Season 6/Power Heroes eventually shows him in possession of the Cat Racer, a single-seater more explicitly designed as a racecar.
• Cool Starship: HQ can transform from a totem pole into a rocket ship for space missions. Season 6/Power Heroes evolves the concept creating a new headquarters for the expanded PJ Masks Power Heroes called Power Q or Space Q. This space headquarters is fully capable of travelling through space.
• Curtains Match the Windows: The PJ Masks trio all have eyes that match their suit color, although Amaya's are brown and change to red when becoming Owlette (because, barring albinism, red is not a natural eye color).
  • Later heroes tend not to play this straight, though Armadylan and An Yu each have eyes that do match the predominant color scheme of their outfits (brown and red, respectively).
• Darker and Edgier: Certain episodes where the villains reach homicidal levels. Such as "Ninja Moths" where the Ninjalinos and Luna Moths try to outright murder Night Ninja and Luna Girl by shooting them off on a rocket. Or in "Moon Madness" where Luna Girl outright tries to murder Catboy by leaving him stranded in space (even though he has a helmet on).
• Darkest Hour:
  • The four-part Season 4 premiere "Heroes of the Sky" is this trope personified in preschool show form via Romeo imperiling the PJ Masks' mission (despite the episode's summary incorrectly mentioning Owlette doing so instead); he destroys Luna Girl's Moon Base, turns Motsuki back into a regular moth, destroys the original versions of the PJ Masks' vehicles and, worst of all, causes Owlette to lose her powers and memories of being a hero by draining her part of the HQ crystal, so Catboy and Gekko are forced to team up with Luna in order to stop Romeo from rapidly cloning all of his flying factories and use them to somehow take over the world, possibly by destroying it.
  • Also the final part of the Season 5 special "Heroes of the Road": Romeo, Night Ninja and Luna Girl perform a successful Villain Team-Up and pull off a plan involving a fake Zoom Crystal to steal both the PJ Masks vehicles and the Speedy Twins' vehicles, then use the same crystal to hypnotize the PJ Riders and turn them against the heroes, capture Newton Star and drain him of his powers, which they then use to take over the city and HQ, with Luna capturing PJ Robot as well. All while the Heroes are forced to hide in the park, left without their equipment, allies or HQ. They only manage to turn the tables because the Speedy Twins agree to an Enemy Mine.
  • Another example occurs at the start of Season 6/Power Heroes in the 4-part premier special "Heroes Everywhere". A larger version of the asteroid that temporarily turned Newton Star evil makes its way to the Earth's vicinity. Newton fears the worst, and the other PJ's get a taste of the evil personality-altering energy when trying to stop Romeo from obtaining it. Romeo manages to obtain the asteroid, however, despite the PJ's and Newton's best efforts, bringing it back to the city in his Flying Factory. While the gang get to know the new kid Ivan during his first day at school the next day, the following nighttime forbodes as An Yu joins Newton and the PJ's in watching in trepidation at what Romeo will do with the evil asteroid. He manages to power himself up with it (and unintentionally turn Robot naughty), as the evil vibes of the asteroid births wicked flowers and angry pigeons across the city. Night Ninja catches wind, and this eventually causes the asteroid to fall to the ground and shatter into fragments, which are drawn across the city to the hands of various Nighttime Villains. Night Ninja and Luna Girl similarly get powered up by these fragments, and together they, the Wolfy Kids in their Wolf Wheelz, and Pharaoh Boy ambush the heroes, ending the night in failure as badness reigns. Things look like they'll take a turn for the even worse when it becomes clear that one of the fragments fell into the pocket protector of new kid Ivan's polar bear onesie. Fearing that this fragment will turn the sweet and heroically inclined Ivan bad, they try and fail to obtain the fragment from the onesie before night falls yet again. The heroes get ambushed once more, and this time, Romeo and the other Nighttime Villains intend to expose the heroes to the fragments of badness to turn them evil just like the Nighttime Villains themselves. Newton flees in fear, and all hope seems truly lost when the fragment in Ivan's onesie, which he is now wearing, activates. Things finally take a turn for the positive, however, as Ivan becomes a new Nighttime Superhero, self-dubbed as Ice Cub; citing a favorite comic for wisdom, Ivan speculates that his inherent good vibes changed the bad vibes from the asteroid fragment into a source of power for him. Together, Newton and Ice Cub are able to take this lesson and counteract the Nighttime Villains' plan, rescuing the other heroes. While the other powered-up villains are still out there and are numerous, Catboy courageously declares that even if there are villains everywhere, there'll also be heroes everywhere to stop them. And, thus, the next iteration of the PJ Masks is born: the PJ Masks Power Heroes!
• The Determinator: No matter how many times the PJ Masks foil them, the nighttime villains always come back for more (though of course this is S.O.P. for comic-book villains).
• Divided We Fall: The heroes have had moments when they try to outdo each other or refuse to cooperate during missions, which usually results in the villains getting the better of them until they realize their mistake.
• A Dog Named "Dog": In "Owlette's Feathered Friend", Owlette adopts a pet bird, whom she names Birdie.
• Dub Name Change: The English names, from the original French:
  • Connor is Sacha.
  • Catboy is Yoyo, Owlette is Bibou, and Gekko is Gluglu.
  • Luna Girl is Sorceline and Night Ninja is Ninjaka.
  • The Mexican Spanish dub, which is subtitled "Héroes en Pijamas", made some modifications to some names, Owlette is Ululette, Gekko's name replaces the first K in his name with a C and goes by Gecko (It's still the same pronunciation), PJ Robot is Robot en Pijama, Night Ninja is Ninja Nocturno, Motsuki is Polisuki, and Luna Girl is simply Luna, the subtitle name is even used as the team's name in this dub.
  • Similarily, in the Italian dub, subtitled "Super Pigiamini" ("Super Jammies"), Catboy is Gattoboy, Owlette is Gufetta, Gekko is Geco, Luna Girl is Lunetta, and Night Ninja is Ninja della Notte.
• Dub Pronunciation Change: In the Italian dub, the team's name is pronounced as "Pijamask".
• Early-Installment Weirdness: In the first season of the series, most of the episodes (except for "Gekko Saves Christmas") generally ended in the daytime.
• Easter Episode: The Season 2 finale "Easter Wolfies" is set during Easter. In the episode, the PJ's have to prevent the Wolfies from stealing the eggs hidden for the next day's egg hunt at their school.
• Egopolis: On at least two occasions, Romeo has tried to convert the city into his own realm, "Romeoville".
• Enemy Mine:
  • Luna Girl teaming up with the PJ Masks against Romeo is the most frequently used example of this trope as this happens in almost every episode they appear in together. She does so in "Gekko and the Mighty Moon Problem" (to stop Romeo from carving his face onto her moon), "Owlette's Luna Trouble" (because Romeo was specifically targeting her to steal her luna magnet and board for his next evil scheme), "Moonbreaker" (to stop Romeo from destroying the moon in his attempt to find the second moon crystal), "Glowy Moths" (after he captures her moths to power up is lab) and "Heroes of the Sky" (after Owlette loses her hero memories and powers to Romeo, thus causing Catboy and Gekko to team up with Luna to stop Romeo for good). Subverted in "Romeo's Crystal Clear Plan" where she willingly both betrays and traps them as well as Romeo and Robot the second she gets her crystal back from the latter; in this episode, she helps herself until PJ Robot stops her (but uses his clones on Romeo) after presumably seeing the whole mission take place on the PJ Picture Player.
  • In "Wolfy Mountain", Night Ninja teamed up with the PJ Masks against the Wolfy Kids to defend Mystery Mountain after the Wolfies deny Gekko's request to share the mountain with Night Ninja.
  • In "PJ Masks vs Bad Guys United", the original three villains (Romeo, Luna Girl and Night Ninja) finally team up (with it being the first time the former two work together despite how much they may hate each other) against the PJ Masks and almost defeat them before Armadylan arrived.
  • In "PJ Comet", Romeo and Luna Girl team up once again, but they still hate and argue with each other.
  • "The Disappearing Ninjas" had Night Ninja team up with the PJ Masks and An Yu against Romeo, since Romeo was taking the Ninjalinos captive for his latest plan.
  • In "PJ Robot vs Romeo", PJ Robot and Romeo had to settle their differences with each other so they can work together to fix the Sky Factory, while the PJ Masks (with Catboy controlling the Owl-Glider) were collecting falling pieces from it.
• Even Evil Has Loved Ones: For all that the villains mock and disrespect their minions, at the end of the day they ultimately do care about them.
• "Everybody Laughs" Ending: Almost all episodes of Season 1 end with the 3 protagonists laughing about something.
• Evil Knockoff: As of Season 3, Romeo has an army of Fly Bots, who are identical in design to PJ Robot (in particular how PJ Robot originally looked in his debut episode), but blindly loyal to Romeo.
• Evil Versus Evil: The Nighttime Villains are not above targeting each other if it means furthering their own goals.
• Facing One's Lost Power: In "Wolfy Powers", Romeo steals the PJ Masks powers, but then they inadvertently get transferred to the Wolfy Kids. The PJ's thus have to try and take their powers back, while figuring out how to do so now that they themselves are powerless.
• Flight: Owlette's wings grant her this. Newton Star and Lilyfay also have this power.
• The Foreign Subtitle: In Brazil, the cartoon is known as "PJ Masks: Heróis de Pijama" (Heroes in Pajamas), this is a similar case for Latin America, where it's know as "PJ Masks: Héroes en Pijamas"
• Four-Fingered Hands: All the human characters, PJ Masks and the Power Heroes,^note Both in their superhero and civilian forms in the case of Connor/Catboy, Amaya/Owlette, Greg/Gekko, Newton/Newton Star and Ivan/Ice Cub, even An Yu in her human form. Nighttime Villains, and civilians all have four fingers.
• Free-Range Children: Aside from the obvious fact that the heroes freely roam the city at night, they also frequently walk around during the day with no adult supervision.
• Frequently Full Moon: The moon is always full, in every episode.
• Freudian Trio: For the PJ Masks, Catboy is the Ego; Gekko is the Superego; and Owlette is the Id.
• Friendly Enemy: The original three nighttime villains. Whenever they team up, do not expect them to get along (although they get along well in while teaming up in PJ Masks vs Bad Guys United). They're also this to the PJs sometimes, such as in "The Disappering Ninjas," "Moonbreaker" or "The Christmas PJ Masks Save Christmas."
• Funny Background Event: Sometimes when a villainous attack is seen knocking over an object, while the battle continues, Gekko will often be seen picking up the displaced object and putting it back exactly where it came from.
• Gender-Equal Ensemble: In season six, the Power Heroes team ends up having four boys (Catboy, Gekko, Newton Star & Ice Cub) and four girls (Owlette, An Yu, Bastet & Lilyfay).
• Genius Loci: Mystery Mountain is sentient. An Yu in particular frequently communicates with the mountain through a dragon statue in the pagoda on top of the mountain, and several plots have the mountain get angry and needing to be calmed down.
• Glad I Thought of It: In "Catboy and the Sticky Splat Slingshot", the Ninjalinos keep voicing their dissatisfaction with Night Ninja's Evil Plan and they're convinced they have one that is better. When Night Ninja finally hears them out, he realizes it actually is better than his and thanks the Ninjalinos for reminding him that he has been planning it all along.
• Go-Karting with Bowser: In "Gekko Saves Christmas", the PJ Masks convince Luna Girl to return the Christmas presents she had stolen and at the end, they give her a present in return, which turns out to be a pair of skates and they all go ice-skating together.
  • Happens in again "The PJ Masks Save Christmas" except this time with Romeo who even says on the holiday season he won't be bad anymore.
• Great Big Library of Everything: The Library in the museum looks like a normal library, but no matter how obscure or unusual the subject is that the heroes or villains need information about (like ancient artifacts, superpowers or even special meteorites), the library will always have a book about it.
• Growling Gut: Briefly happens to Gekko after eating too much chocolate in “Easter Wolfies”.
• Halloween Episode:
  • The two-parter "Halloween Tricksters" is set during Halloween. Minus one point for the PJs going out as themselves, just because they want to keep the other kids from finding out who they really are.
  • The show got another one in season 5; "Trick or Treat". Again, it's a two-parter.
• Henshin Hero: The PJ Masks only have their powers while in their superhero identities.
• Heroic Second Wind: Any time a character makes a mistake and/or starts to doubt themself, after some encouragement to make things right, said character will shout "Time to be a hero!"
• Hero Worship: Connor idolizes the martial artist, Master Fang, while Amaya loves the comic book superheroine, Flossy Flash.
  • In "Catboy and Gekko's Robot Rampage," Greg also has a passion for Master Fang's sidekick Kick McGee.
• Hiccup Hijinks: "Trick Or Treat" has Luna Girl get hiccups when she eats a cursed apple.
• Hoist by His Own Petard: Occasionally happens to the nighttime villains. For example:
  • In "Speak UP, Gekko!", Romeo ends up losing his own voice to his invention he created to steal the voices of the PJ Masks.
  • In "Catboy and the Sticky Splat Slingshot", Night Ninja has the PJ Masks stuck to a giant ball of sticky goo and is about to shoot them out at their headquarters with the titular slingshot. After getting shot out, the heroes manage to free themselves and throw the ball back at Night Ninja and his Ninjalinos who end up stuck to the ball themselves and rolling around with it all over the town.
  • In "Moonfizzle Balls", the heroes use Luna Girls own Moonfizzle Balls against her.
  • Romeo literally gets hit with this hard in "Clumsy Catboy" when his Clumsy Ray ends up hitting him while sitting in his lab.
  • Similarly, Romeo is defeated in "Gekko and the Missing Gekko-Mobile" when his "rotten-ated" eggs end up falling on him.
• Hollywood Chameleons: Gekko can change into any color at will.
• Hover Board: Luna Girl's Luna Board.
• Human Aliens: Lilyfay is a space fairy who lives on the other side of the universe, but compared to the Speedy Twins and Gloop III, she doesn't look any different from a regular human girl and could easily pass for one if not for her space powers.
• Idiosyncratic Episode Naming: Every episode title of season 1 includes at least one of the heroes' names. This has been toned down as of season 2.
• Invisible Parents: None of the heroes' parents/guardians ever appear on screen, and are just mentioned in passing. Nor do we see the parents of the villains (assuming they have any).
• Ironic Name: Connor. His name means "wolf/dog lover" in Irish, but he's a cat superhero.
• Irony: Ninjas are supposed to be stealthy, hiding in the shadows and keeping their existence a secret. Night Ninja is openly showy and craves the spotlight, wanting everyone to know him. Justified as he is a child.
• It's All About Me: All the nighttime villains fall into this, but Night Ninja is the worst, constantly trying to make himself look good at the expense of others, and ignoring his Ninjalinos whenever they try to offer their own ideas.
• Jerkass: All the villains count, but as of Season 4, Octobella and Pharaoh Boy are the most unpleasant and rotten of all the other nighttime villains, with the former even regularly pushing her own sidekick around beginning with "Magnet in the Moat."
• Jerkass Has a Point:
  • In "Owlette's Feathered Friend", Luna Girl wasn't wrong when she points out to Owlette that due to the fact that she didn't look after her new pet properly, Birdie put her luna crystals inside their HQ. Even Gekko said that Luna Girl's right when she tells Owlette that she's a terrible pet owner, which Owlette immediately admits.
  • In "Speak UP, Gekko!", Romeo wasn't wrong when he (using the P Js' voices) calls Gekko out for his inability to get the Voice Box once he has successfully stolen Catboy and Owlette's voices, though Gekko doesn't admit that it was his fault until he acquires Owlette's voice.
  • In "Gekko's Blame Campaign," Cameron chews out Greg for losing his toy car, declaring he's never letting him borrow any of his stuff again. Greg had left the car outside all night (allowing Luna Girl to steal it), and even Connor and Amaya point out how irresponsible that was.
• Jerk with a Heart of Gold: The original three nighttime villains. To their minions, sometimes, anyway such as in "Ninja Moths" and "Nobody's Sidekick". But sometimes towards the PJ Masks as well for example such as in "Wolfy Mountain", Moonbreaker" and "PJ Masks Save Christmas".
• Just Hit Him: The three leads' superpowers are pretty effective for fighting: Catboy is super fast and agile, Owlette can fly and control wind, and Gekko is a Yautja who can climb walls like Spider-Man and use super strength. However, this being a kids' show, they never use them for anything above basic problem solving; only occasionally do they engage in hand-to-hand against the villains, even if it would typically save the day much faster than trying to play into the baddie's rules. As of Season 4, this trope has been subverted a couple of times in fights against Romeo's Fly Bots, but these fights always happen off screen, likely to keep kids from being exposed to violence.
• Karma Houdini: The nighttime villains never get their comeuppance for constantly messing with people, stealing, freezing everything in the middle of summer, trying to take over PJ Masks' HQ with a pet bird, etc. Although Romeo did end up losing his own voice in "Speak UP, Gekko!" but that's about it. And then he appears perfectly fine in the next episode he's in.
• Kid Hero: The P Js are often said to be six.
• Kids Driving Cars: Each of the three main P Js has their own signature vehicle, while nighttime villain Romeo drives a mobile lab resembling a street-sweeper.
• Lesser of Two Evils:
  • In seasons one and four, Luna Girl is this, compared to Romeo and Night Ninja. While the two other villains' schemes often revolve around Take Over the World tactics and proving their superiority, she mostly just steals things so she can play with them, with no greater plan usually involved. On several occasions, the PJ Masks have been able to negotiate a truce with her, or convince her to halt her plans by giving her something that she would like.
  • In seasons two and three, this is averted. Not only is she now more dangerous with a luna wand and crystal she's far more homicidal. For example, in "Moon Madness," she tries to turn off a beam in space that would leave Catboy stranded in space and die, despite him wearing a helmet and his friends eventually saving him.
  • The fifth season introduces the Speedy Twins, Carly and Cartoka. Despite being responsible for the destruction of the PJ's vehicles, all they ever really care about is speed and looking for ways to upgrade their Flashcar.
• Let's You and Him Fight:
  • In "Clash On Mystery Mountain" Night Ninja tricks Armadylan into fight An Yu and take her staff from her.
  • Also, in "It's A Cat Thing", due to a misinterpretation of an ancient tablet by Gekko, Catboy & An Yu are tricked by Pharaoh Boy into fighting Bastet.
• Lighter and Softer: Despite its dark side (no pun intended), it's still a kids show that teaches children to not be afraid of the dark. It's also considered to be a kid-friendly equivalent of the slightly more adult-oriented Miraculous Ladybug, but with pyjamas.
• Magitek: The heroes have access to a high-tech HQ that contains among other things a Holographic Terminal and can turn into a rocketship, as well as high-tech individual vehicles, all of which would not be out of place in a science fiction series. Yet, it's all powered by a Magical Crystal Totem, directly tied to the PJ's own powers^note In the season 4 premiere, the vehicles exploded when Romeo imperiled the team's mission, but suddenly reappeared with upgrades via three crystals that evolved when Owlette gave two of them to Catboy and Gekko after somehow regaining her hero memories and powers, and when HQ underwent and upgrade in season 5, the PJ Sensors spontaneously materialized from tree branches inside HQ.
• Make My Monster Grow:
  • In "Super-Sized Gekko", an invention of Romeo makes both Gekko and one of Luna's moths grow giant.
  • In "Lionel-Saurus", another invention by Romeo which resembles dog treats turns Gekko's pet lizard Lionel huge.
  • In "Halloween Tricksters", Luna Girl uses the power of the Halloween moon to make three of her moths grow to gigantic size.
• Mid-Season Upgrade:
  • In the season 2 episode "PJ Power Up," all 3 PJ masks get new powers thanks to a crystal statue found by PJ Robot in HQ ^note However, due to the Anachronic Order mentioned above, these new powers were first seen alongside PJ Robot in "Wacky Floats".
  • In the Season 4 premiere "Heroes of the Sky," three crystals retrieved by Owlette turned into upgraded versions of all three of the PJ Masks' original vehicles when she handed two of them to her teammates.
  • This happens twice in Season 5; in the premiere "Ninja Powerup," the PJ Masks gain even more powers, even though they only used their new powers in said premiere, with HQ getting a powerup as well, giving it a new appearance and the PJ Sensors, and the episode "The PJ Riders Save the Day" sees the PJ Masks' Thememobiles gaining new powers (which, coincidentally, are the exact same powers the PJ's themselves gained in Season 2) upon retrieving them from Carly and Cartoka.
• Minimalist Cast: While other kids are often seen during the daytime segments, the majority of the show focused on initially only eight main characters: the 3 PJ Masks, Romeo, Luna Girl, Night Ninja, the Alley Cat and Lionel (though the latter two were only minor characters up until "Ninja Power Up"). The trope has since gradually been downplayed with each season introducing more main characters^note Season 2 had Armadylan, PJ Robot and the Wolfy Kids, while Season 3 had Motsuki and An Yu (the Splat Monster doesn't count, since he and Teeny Weeny are one and the same). Season 4 gave us Newton Star, Munki-Gu, Octobella and Pharaoh Boy. Finally, Season 5 introduced Owly, Orticia, Pirate Robot, the Speedy Twins and the PJ Riders, with Season 6 debuting Ice Cub and Gloop III, as well as the cartoon counterparts of original book series characters Lilifée (now known in English as Lilyfay) and Bastet, though as of the season 6 episode "Space Fairy Hero," the show only has a cast of about 30 (32 if you count Octobella's sidekick Percival and Pirate Robot's official sidekick Sally) main characters. Still, since the villains take turns fighting the heroes, and the supporting heroes also usually rarely appear together, there's still only around 7 - 8 main characters per episode.
• Mishmash Museum: The museum doubles as a library, and has dinosaur skeletons, an Egyptian exhibit and artwork as part of the permanent exhibits, with a large variety of new exhibits being added whenever the plot demands it, such as magical artifacts and the seed from which Romeo created Orticia.
• Moral Myopia: The nighttime villains often yell at the PJ Masks for "ruining everything" when their plans are foiled, conveniently ignoring the fact that those plans would often ruin things for everyone else.
• Mysterious Past: Goes for pretty much ALL heroes and villains. Due to the show currently lacking a proper Origins Episode for the majority of its characters, it's unknown how the three main heroes and villains became who they are now, or how they first met. The episode "Catboy Does It Again" proves the PJ Masks didn't always have their powers since Romeo planned to revert them back to before they were heroes, but that's about it.
  • Slightly downplayed for the characters introduced from season 2 onwards; we do get to see their first encounter with the PJ Masks, but not how they got their powers. The only villains to have origins are Motsuki, Orticia and Pirate Robot (until he reformed), and the only heroes to get one are PJ Robot (although his proper debut premiered after "Wacky Floats") and Ice Cub.
  • An Yu also qualifies; we only know that she was at some point in the past sealed away in the dragon gong, but nothing else is known about how, when and why this happened, or how for long she was the guardian of Mystery Mountain at that point.
  • This is partially subverted as seen in the official FrogBox website, which states that the Spirit Animals were responsible for creating the PJ Masks' costumes. Furthermore, one official bio image in an official PJ Masks account confirms that the main characters met in a sandpit at school, but this isn't entirely true, so it is unknown where the main characters actually first met each other and how they gained their powers.
• Mythology Gag: The concept art for Luna Girl shows her with a wand instead of a magnet as a weapon. As of the season 2 episode "Moonstruck", whenever Luna Girl combines her magnet with the moon crystal, her magnet becomes this wand.
• Narcissist:
  • Romeo. In "Gekko and the Mighty Moon Problem," he tried to carve his face into the moon.
  • Night Ninja has a giant statue of himself made in "Owlette's Two Wrongs".
• Never My Fault: Night Ninja and Luna Girl are quick to blame their minions when their plans fail such as "Ninja Moths."
  • In "Slow Down, Catboy!" Luna Girl uses her Luna Magnet on Night Ninja to cheat, only for both of them to crash and lose. Luna blames Night Ninja for her own backfired plan.
  • In Octobella's debut episode, Gekko tries telling her that Romeo tried to take the moat's pondweed, to which she quickly puts the blame on Gekko (even though he was only trying to return it), thus causing her to claim that said pondweed belongs to her and setting up her rivalry with him.
• Never Recycle Your Schemes: While this is common in most episodes, it is averted in "Owlette's New Move", where Romeo reuses three of his old plans at the same time. Some of his other inventions are also used more than once, though sometimes by other villains instead of him.
• New Season, New Name: Season 6 is named Power Heroes, reflecting the fact that the PJ's expand their team with six additional members in the form of three new heroes specifically for the season, with the other half of them being pre-existing allies.
• Nice Job Breaking It, Hero!: The show's typical plot structure involves one of the main characters demonstrating a personality flaw that will later screw up the team's plan. This usually leads to the episode's "It's time to be a hero!" moment.
• Nice Job Fixing It, Villain!: There are four episodes in Season 3 and one in Season 6 where the nighttime villains created a problem for themselves that ended in the PJ Masks' favor or gave the trio sympathy.
  • Night Ninja did this big time in the episode "Meet An Yu". He and his Ninjalinos steal the Dragon Gong from the museum, and take it to Mystery Mountain where he intends to force the dragon that resides inside the gong to help him rob the pagoda of all its relics. Too late does he learn that the dragon is actually An Yu, the protector of Mystery Mountain, who was imprisoned in the gong, and by bringing the gong back to Mystery Mountain, he allowed her to finally break free, giving the PJ Masks a new powerful ally in the process.
  • In "The Moon Prix", after when Catboy and the Wolfy Kids crashed their vehicles, Luna Girl and Romeo, fired their weapons at Catboy, while Catboy dodged it, the blast hit the Wolfies vehicles, which inadvertently created the Wolf Wheelz, after the Wolfies won the race with help from the full moon which gave the Wolf Wheelz a massive speed boost, the Wolfies give Catboy his Cat-Car back which was shrunken by Romeo as part of the trophy, as they stuck with their new vehicle since it's much cooler to them.
  • In "Wolfy Powers", when the PJ Masks have their powers stolen by Romeo with his invention, the Vacuum of Doom, the Wolfy Kids bumped into Romeo and grabbed the orb that holds the PJ Masks' powers, giving them the heroes' powers, preventing Romeo from having the heroes' powers to himself, thus giving Connor, Amaya, and Greg the advantage albeit rocky road to get their powers back.
  • In "Clash on Mystery Mountain", when Night Ninja tricks Armadylan into getting Night Ninja An Yu's staff and sends An Yu back into the Dragon Gong, basically as a way to undone his mistake of freeing her from a few episodes ago, this caused Teeny Weeny to have a change of heart, when he sets up the scrolls for Night Ninja to unlock the secrets of the mountain and when the PJ Masks enter into the pagoda to stop Night Ninja, Tweeny Weeny has had enough, and teleports Night Ninja back to the city, and leaves the staff/mallet for the PJ Masks, freeing An Yu from the gong, and An Yu would reward Teeny Weeny in the following episode, "A Teeny Weeny Problem", thus turning against Night Ninja ever since, Night Ninja really messed that up, twice.
  • In "The Super Gloopster", while the Speedy Twins implement upgrades for Gloop The Third's ship, Cartoka forgot to include window wipers, thus allowing Owlette to hit the upgraded Gloopster when Gloop fires at her and allowing the twins to escape.
  Cartoka: Window wipers. I knew I forgot something.
  Carly: Uh-oh!
  (The Gloopster crashes into the ground.)
  Carly: Time to split, bro!
  Cartoka: You know it, sis.
• No Antagonist: The season 3 episode "Super Muscles Show Off" stands out as the first, and so far only, episode in which none of the nighttime villains appear. Instead, the conflict comes from a contest of strength between Gekko and Armadylan, which quickly gets out of hand.
• No Flow in CGI: Aside from Owlette's cape, none of the characters' hair is ever shown being blown around whenever there's wind. Justified, since hair is very difficult to realistically animate in CG.
• Not Allowed to Grow Up: Official sources state that the main heroes are six years old at the start of season 1, yet despite the show having had three separate Christmas specials and at least two episodes about Gekko's birthday, none of the characters ever age or move to another class and still have the same teacher. The sole exception is An Yu, who is 2001 years old as of Season 6.
• Not Me This Time:
  • In "Catboy and Gekko's Robot Rampage", Romeo's robot steals all the toys from the playground and when the heroes confront Romeo about it, he tells them the robot is not obeying him and stole them on its own will.
  • In "Bounce-a-Tron", the PJ Masks suspect Romeo to be behind the sudden appearance of green, bouncy splat all over the city, but it turns out it was actually Night Ninja, who stole Romeo's Bounce-a-lot Machine to do so. Subverted in that once Romeo gets his invention back, he immediately starts using it to cause more trouble for the PJ Masks.
  • In "Owlette Slips Up", Owlette suspects Romeo to be behind using his inventions to cause havoc all over the city, but it turns out she was (indirectly) helping the Wolfy Kids, who stole Romeo's Ice Machine to do so.
• Odd Name Out:
  • Amaya/Owlette is this, as unlike the other two PJ Masks, her normal name and superhero name do not start with the same initial. In the French version, only Greg/Gekko's name and superhero name start with the same initial (see Dub Name Change above).
    • Averted for the Russian dub, where Owlette's name is adapted as Alette to match her daytime name.
  • And then there are the Wolfy Kids who are named Howler, Rip... and Kevin.
• Origins Episode: The "Heroes Everywhere" special at the start of season 6 serves as one for Ice Cub, making him the first hero in the series to actually get one.
• Our Dragons Are Different: The season 3 character An Yu is a magical dragon who can turn into a human upon leaving her gong.
• Our Werewolves Are Different: The Wolfy Kids. Physically, they mostly resemble the beastman version of werewolves (human-looking, but with claws on their hands and feet, sharp teeth, pointy ears and long messy hair). They also display typical wolf behavior like running on all fours, howling, and biting, but can also walk bipedally, and are still capable of human speech.
• Passionate Sportsgirl: If the episodes "Owlette and the Moon Ball" and "Owlette the Winner" are any indication, Amaya is one.
• Performance Anxiety:
  • Greg suffers this in "Speak UP, Gekko!" when he has to recite a poem in front of his whole class. Eventually, his whole class laughs at him, possibly even Connor and Amaya!
  • Connor also gets this in "Catboy's Great Gig" when he's nervous about having to play an instrument in front of the class. This time however, he doesn't get laughed at by his friends or the class.
• Pirates Vs Ninjas: It happens two times in "Pirates Ahoy" and "PJ Sky Pirates" when the PJ Masks were dressed up as pirates to stop Night Ninja.
• Promotion to Opening Titles: After using the season 1 opening sequence all thru season 5, season 6 finally gave the show a new opening sequence featuring all three of the new heroes, as well as Armadylan, An Yu, Newton Star and most of the villains that had been introduced over the past seasons. The only characters still absent are Munki-Gu and Orticia, both of whom are confirmed to not be returning, as well as Owly & Lionel of the PJ Pets, PJ Robot, Pirate Robot, Carly, Cartoka, the PJ Riders (probably due to the theme song not having enough room for any of these characters) and Gloop III.
• Punny Name:
  • The French name of the show is actually a pun on pyjamas (pyjamasques <-> pyjamasks, see?). It's more obvious in the original French which pronounces it exactly like "PJ Masks"; English chose to keep the pronunciation the same at the expense of the pun being slightly lost.
  • Owlette is the female name "Olette" with a "W" added to have the word "Owl" in it. The name Olette means "small winged one" in latin, making this a Meaningful Name as well.
• Quarter Hour Short: Each episode consists of two 11-minute long stories, except for specials like "Moonstruck" and "Heroes of the Sky, which are a half hour and hour long, respectively.
• Redemption Rejection: After helping the PJ Masks defeat Romeo in "Gekko and the Mighty Moon Problem," Owlette offers Luna Girl a spot on the team. Of course, she refuses and claims that she wants to stay a villain.
• Ret-Canon: When the books were adapted for television, several changes were introduced which, after the show became a success, were retroactively introduced in the books as well (starting with book 19, Les Pyjamasques et l'opération zéro). Most notably, book counterparts for the PJ Masks' vehicles, Luna Girl and Night Ninja, and Les Pyjamasques receiving the PJ's new powers.
• Resized Vocals: Any time a character is shrunken or grows big, their voices will wither raise or drop a few octaves.
• Robot Buddy:
  • Robot, Romeo's primary ally.
  • As of the season 2 episode "PJ Robot", the PJ Masks themselves also have one named PJ Robot. ^note But due to the Anachronic Order mentioned above, he was first seen alongside the PJ Masks' new powers in "Wacky Floats."
  • Season 5 sees Pirate Robot, a robot himself, get his own buddy in the form of Flybot Sally
• Rule of Empathy: This super kids show teaches other people to be kind to one another, including the PJ Masks themselves to listen to each other's feelings and hearts.
• Save the Villain: Since they're heroes, the PJ Masks will help the night time villains when they're in trouble, even if they don't like having to do so. A few examples:
  • Owlette saves Romeo from falling in "Catboy and Gekko's Robot Rampage".
  • In "The Good Wolfy", the PJ Masks, helped by Kevin, save Rip and Howler from falling off HQ.
  • In "Best Friends Forever", when Luna Girl falls out of the HQ rocket and ends up drifting in space, with an asteroid storm heading her way, Owlette went out into space as well to rescue her, soon followed by Catboy and Gekko. And when it seemed they wouldn't be able to all return to the rocket, they offered Luna the chance to leave them behind and get herself to safety first, only for Luna to carry the P Js into the rocket with her Luna Magnet so that she wouldn't leave them in space to die.
• Science Fantasy: The show freely mixes elements of both genres. On the fantasy side, there are characters like Night Ninja and An Yu, and adventures involving ancient artifacts and Mystery Mountain. On the sci-fi side, there are characters like Romeo, Luna Girl, PJ Robot and Newton Star, and adventures set in space. The three main heroes are a mix; their powers are more on the fantasy side, with them using magical bracelets to transform into heroes, a crystal totem containing animal spirits that power their costumes and HQ, and tap into the animals their powers are based on, but on the other hand they also have high-tech vehicles, and an HQ that can transform into a spaceship.
• Ship Tease: Usually with Luna Girl of all people, perhaps because she is the most sympathetic villain and was the villain most likely to team up with the PJ Masks in the first season (and, at least during season 1, the only female villain).
  • Catboy and her get a bit of it in "Catboy's Cloudy Crisis" when their struggle for the Luna Magnet somehow turns momentarily into a tango. He appears to enjoy it more than her, however.
  • She also gets quite close with Gekko in "Gekko Saves Christmas" after he invites her to spend Christmas with the trio and they have some gaze meeting moments.
    • Also, the short "Training With The PJ Masks" and the Halloween special "Halloween Tricksters (Part 1)" have Luna Girl falling off her Luna Board and Gekko catching her bridal style with a huge grin on his face. Then we see Luna Girl’s cheeks looking more rosier than before.
    • Plus in "Fly Me to the Moon," Luna Girl and Gekko are seen sitting together on his bed in his bedroom and talking with each other.
    • And in "PJ Party Crashers," Luna Girl catches Gekko when he was falling and he thanks her, much to Luna’s embarrassment.
  • Catboy and Owlette also get a bit of it at times:
    • In "Owlette and the Battling Headquarters", Owlette falls down after a failed attack on Night Ninja and Catboy catches her in bridal style. A very brief look on his face indicates that he enjoyed the situation a bit more than just helping a teammate in need.
    • In "Catboy's Tricky Ticket" Amaya tries to convince Connor to give her his spare ticket for the Jayden Houston concert by telling him she could help him practicing his skateboard moves. Taken out of context, the scene could easily be read as Amaya flirting with him.
    • In "Not So Ninja," Owlette catches Catboy when he is falling from the museum and they smile affectionately at each other.
    • In the end of "Heroes of the Sky," Catboy and Owlette end up hugging each other after Motsuki turns back to her current form.
  • Owlette spends the majority of "An Yu's Birthday" being very touchy-feely with the titular dragon girl, and in some scenes almost appears to give her bedroom eyes.
  • Speaking of An Yu, there are several episodes since Season 3 where Gekko and An Yu have an affection for each other.
    • In "Meet An Yu", after when she was freed from the Dragon Gong by Night Ninja and when the PJ Masks are falling down the mountain, An Yu catches Gekko by holding hands, and at the end, she does a high five with him.
    • In the Season 4 episode "Wolfies of the Pagoda", the Wolfy Kids' sonic howl sends An Yu falling down Mystery Mountain, Gekko catches her, and An Yu gives a weirdly suggestive face when this happened.
    • In "Munki-Gu's Dragon", when Gekko is shielding himself and his teammates as not to get cursed for a thousand years, when Munki-Gu turned Greg/Gekko's favorite float, the Laughing Lizard into a real dragon with the Dragon Potion Munki-Gu stole from the pagoda, An Yu sacrifices herself to the curse to save Gekko, but is freed thanks to the power of friendship, and Gekko thanks her and calls her buddy.
    • In the Season 6 episode, "An Yu and the Gekkos", when An Yu apologizes to Gekko for not working together as a team, her eyes light up.
    • Gekko rides on An Yu's staff, at the end of the episode, "Robot the Hero", and in the video game tie-in "PJ Masks Power Heroes: Mighty Alliance" and in the case of the latter, Gekko holds onto An Yu by her hips when riding on her staff.
    • In "Romeovision", An Yu and Gekko got sucked into Romeo's titular invention; when An Yu can be seen snickering when Gekko mocks Romeo.
  • Lilyfay and Ice Cub get some as well, as evidenced by their interactions in "Space Fairy Hero" and especially "Heroes of Iceworld".
• Shout-Out: In the episode "PJ Robot Takes Control", when PJ Robot shows Catboy, Owlette, and Gekko the hacking control program, Robot Party, the cartridge is in the shape of the one for the Nintendo Entertainment System video game console.
• Sick Episode: "Gekko's Stay-at-Home Sneezes."
• Sliding Scale of Continuity: For most seasons, the show is on level 2; each episode is a wrapped up, standalone story, but there is a sense of continuity as characters will sometimes recall events from a previous episode and occasionally there is an episode that introduces a lasting change to the status quo like a new character or the heroes getting new powers. In Season 5, the show shifted towards level 3 by introducing two overarching plots that lasted for multiple episodes: one involved the Speedy Twins stealing vital parts from all the PJ Vehicles, rendering them useless and forcing the PJ Masks to rely on their new PJ Riders while trying to get the stolen parts back; the other involved Luna Girl being banned from the Moon after a huge argument with Motsuki, after which she spent multiple episodes plotting to somehow get back there. Both of these were resolved by the season finale and the sixth season returned the show to level 2.
• Slumber Party: Amaya throws one in "PJ Party Crasher." Since she knows Luna Girl will probably try to ruin it, she convinces Jenny and Marie to make it a costumed party so she can go as her superpowered alter-ego without raising suspicions.
• Small Name, Big Ego: Night Ninja. Most of his schemes involve proving he's the greatest and most skilled person around.
  • Romeo can also fall into this.
• The Smurfette Principle:
  • Owlette is the only girl amongst the main trio, and was the only female hero overall in seasons 1 and 2. Season 3 introduced An Yu (whose dragon form already appeared in season 2), but she is a supporting hero who only appears in select episodes alongside Armadylan and Newton, leaving Owlette to remain the only female PJ Mask. However, An Yu and Newton become recurring heroes in Season 6, which also introduces Bastet, Lilyfay and Ice Cub, so since there are now four main heroines in a group of nine, Owlette is no longer the only female main heroine.
  • On the side of the villains, Rip is the only female Wolfy sibling. Before her and her brothers' introduction, however, Luna Girl was the only female villain overall.
• Spoiled Brat: Luna Girl comes off this way sometimes, screaming and throwing tantrums when the things she's stolen are taken away from her by the heroes.
• Spoiler Opening: The new theme song for the sixth season shows all the new and old members of the Power Heroes together, as well as the three original villains (Romeo, Luna Girl, and Night Ninja) with their new outfits.
• Status Quo Is God: Downplayed; while most episodes are stand alone stories whose events are forgotten by the next, there have in fact been several episodes that did cause lasting changes in the show's status quo. These include the introductions of new heroes and villains, the heroes getting new powers, their vehicles and HQ getting an upgrade, Teeny Weeny permanently ditching Night Ninja to become a hero, and Motsuki becoming Luna Girl’s surrogate sister, but eventually having a falling out with her and banishing her from the Lunar Fortress. The Season 5 episode "Carly and Cartoka" saw another major change to the status quo, with all the PJ vehicles (including their Thememobiles, which had been part of the show since the very beginning) being destroyed by the titular twins, and the heroes failing to get them back in favor of freeing the PJ Riders from the HQ Crystal; however, the PJ's did manage to retrieve and repair their Thememobiles in the season 5 episode "The PJ Riders Save the Day."
  • However, season six frequently brings back/references events from all six seasons. For example, characters in the season six episode "Heroes Everywhere" mention the events of the season five episodes "Newton the Destructor" and "The Power of Mystery Mountain" a few times, and a character the season six episode "An Yu and the Gekkos" mentions the events of "Catboy Squared" once.
• Strong as They Need to Be: The show is frequently guilty of this, most notably with Gekko's Super-Strength (one moment he easily lifts heavy objects over his head, another moment a villain easily restrains him) and Catboy's Super-Speed (sometimes he can perform feats that rival The Flash, other times he's certainly fast but still slow enough for a villain to intercept or dodge him). Owlette is the only exception to this as she only has Flight and wind-based powers.
• Stopped Reading Too Soon: The episode “Armadylan Zen” has Catboy take Armadylan to Mystery Mountain to help him control his temper, using techniques from a book he read about how to stay calm. One of these techniques involves climbing the mountain of strength to attain inner peace. But when they get to the top and Armadylan’s anger gets the better of him again after being provoked by Night Ninja, Catboy realizes that book actually meant climbing one’s “inner mountain”; he never read past the last part.
• Subverted Rhyme Every Occasion: Invoked by Luna Girl in "Catboy's Tricky Ticket" after she steals popstar Jayden Houston's golden microphone.
  Luna Girl: I've got Jayden's golden mike, and I can do just what I waaaaant!
• Superhero Speciation: Played straight in the initial team, where all three members had distinct powers and abilities not shared with any of their two teammates As more and more heroes were introduced, the trope was downplayed with some of these heroes having at least one power similar to another hero in the team (Gekko and Armadylan both have Super-Strength as their main ability, while Owlette, Lilyfay and Newton can all fly), however they still have secondary abilities to set them apart from the rest (Gekko also has Wall Crawl and invisibility, while Armadylan can perform a Rolling Attack).
• Superman Stays Out of Gotham: Over the course of the series, as the main PJ's gain more allies, it becomes quite noticeable that for some reason they never ask these allies for backup whenever they find themselves in a tight spot. Season 6 in particular is guilty of this; each episode, all the heroes gather in their new Space HQ to discuss that night's mission, but then they only pick 1 - 3 members to go on the mission and once the choice has been made, these heroes are somehow on their own for the remainder of the episode. No matter the trouble they face, they never even consider calling their fellow heroes in HQ to come to their aid, nor do these other heroes keep an eye on how the mission is going and decide for themselves they should go down to Earth and help.
• Sweet and Sour Grapes:
  • In "Gekko and the Rock of All Power," Gekko gets caught up in competing with Night Ninja to break the eponymous rock and get the amulet, putting the city in danger as they knock it around. It's not until Gekko tries to break the rock to save his friends that he finally succeeds.
  • In the season five episode "Carly and Cartoka," the heroes end up having their vehicles stolen and destroyed by the titular twins. They don’t get them back at the end of the episode, but thanks to the help of the PJ Pets, they instead gain three giant animals to serve as their mounts. That is, until the they do get their vehicles back later in the season.
• Sympathy for the Devil: Even though the PJ Masks stop villains from ruining daytime fun, they still extend kindness to some villains, primarily Kevin.
• Take Over the World: Romeo's main motive; something he frequently admits.
• Technically Living Zombie: In "Moonfizzle Balls", Luna Girl uses her titular Moonfizzle Balls to turn everyone in the city into her minions. Those affected act like stereotypical zombies, walking in a Zombie Gait and droning "Moooon". The heroes even have to act like they got affected to get close enough to Luna for a counterattack.
• Thememobile: All three young heroes have their own vehicle: the Cat-Car (a blue automobile), the Owl-Glider (a red aircraft with owl wings) and the Gekko-Mobile (a green amphibian vehicle with a lizard tail). Newton and Ice Cub also get their own vehicles in season 6 in the forms of the Newtron and Ice Dasher, respectively.
• Third-Person Person: Catboy is prone to talking like this, usually when he's about to do something heroic.
  • Motsuki, however, talks like this more often than Catboy.
• Two Shorts: Episodes are made up of two 11-minute segments.
• Tomboy and Girly Girl: Owlette and Luna Girl. An Yu and Rip. Bastet & Lilifay
• Tom the Dark Lord: The Wolfy Kids are named Howler, Rip... and Kevin.
• Took a Level in Badass: As the series progresses, the PJ Masks and several other characters have gained new vehicles, gadgets, upgraded versions of their original vehicles and so on.
• Took a Level in Jerkass: Catboy and Owlette sometimes in episodes that focus on them. Prime examples include:
  • "Catboy and the Butterfly Brigade" and "Catboy Takes Control" for Catboy.
  • "Owlette the Winner" and "Owlette and the Owletteenies" for Owlette.
  • Luna Girl in season 2 and 3 also fits into this. Not only is she more dangerous she is also more homicidal being willing to try and leave Catboy stranded in space and die even with his helmet on in "Moon Madness".
• Town Girls: Out of the four girls of the Power Heroes, Lilyfay is the bubbly Femme, An Yu (disciplined Action Girl) and Owlette (Girly Girl with a Tomboy Streak) are Neither, and the rambunctious Bastet is the Butch.
  • This also applies to the female villains. Octobella is a manipulative Femme, Luna Girl is the Neither (Tomboy with a Girly Streak), and Rip and Carly are both the Butch.
• Transformation Name Announcement: Each of the PJ Masks announce their names after they transform.
• Transformation Sequence: The PJ Masks each have one Once per Episode.
• Transformation Trinket: Though their pajamas give them their powers, the trio activate them via wrist bands.
• Troll: In the episode "Gekko's Blame Campaign" Luna Girl attempts to get a rise out of Gekko by taunting him while riding on a racecar she stole in an attempt to get him to knock the HQ loose in the process.
• Universal Driver's License: Despite being 6-years old, all three heroes have no trouble piloting their respective vehicles (a car, a plane and an amphibian vehicle respectively), or each others vehicles if the situation demands it. In "Take to the Skies, Owlette," Catboy and Gekko likewise had no trouble flying an old plane from the museum.
• Unusual Euphemism: Each of the PJ Masks have their own set of themed exclamations, such as "By my cat's whiskers!" (Catboy), "Fluttering feathers!" (Owlette) and "Gasping geckos!" (Gekko).
  • At one point in "Wolfy Mountain," Howler screams "Yackadoodle!"
• Vague Age: Despite official sources stating that the heroes are six years old, they act far more mature than one would expect for kids their age.
• Villain Episode: The episode "Romeo's Disguise" focuses entirely on Romeo and not on the PJ Masks, though the P Js themselves did get some occasional screen time.
  • Each of the Wolfy Kids has had at least one episode for themselves: "Way of the Woofy" for Howler, "The Wolfy Plan" for Rip, and "The Good Wolfy" and "Moonwolfy" for Kevin.
• Villain: Exit, Stage Left: Upon being defeated, the nighttime villains always flee and the heroes don't really make any attempts to stop them from escaping, instead having mercy on them and letting them get away.
• Villainous Rescue: In "Bounce-A-Tron," Romeo ends up taking care of Night Ninja who has the Masks bouncing around and with Night Ninja defeated he accidentally makes it easier for the heroes to win after they stopped bouncing.
• Villain Song: Romeo, Luna Girl, and Night Ninja each have one in the form of a short music video.
• Villain Team-Up: The nighttime villains sometimes go into these, though they always fall apart due to differences of opinion or motives. The largest team-up so far was in "Halloween Tricksters" and "PJ Masks vs Bad Guys United," with Luna Girl and Night Ninja working together with the Wolfies and Romeo respectively.
• Wall Crawl: One of Gekko's powers. His vehicle, the Gekko-Mobile, can also do this.
• Welcome Back, Traitor: The Ninjalinos sometimes ditch Night Ninja for the PJ Masks, but he still always takes them with him when he retreats anyway. Exaggerated in his debut episode where the titular Ninjalino flat out told him he doesn't want to help him (which Catboy does instead) because he likes the PJ Masks but ended up being easily forgiven.
  • This is eventually subverted for the latter in "Teeny Weeny Returns" as he has shown remorse on helping Night Ninja and decides to work with the heroes from then on.
• We Will Meet Again: Frequently said by the nighttime villains upon being defeated.
• What Measure Is a Non-Human?: While the PJ's never harm their Ambiguously Human opponents and only use their powers in non-harmful ways, Romeo's robots are not so lucky. In particular the Flybots, who are essentially drones with no personality, have more than once found themselves on the receiving end of the PJ’s powers, and can freely be used to demonstrate how dangerous the young heroes can be if they do use their powers for combat.
• What the Hell, Hero?:
  • Presumably happened in "Speak UP, Gekko!", where Connor and Amaya are implied to laugh at their own friend with the whole class.
  • Noticed in "Race Up Mystery Mountain", where the PJ Masks were supposed to retrieve the Mystery Mountain Scroll from Night Ninja, but instead forgot about it and let him keep it, causing them to change their mission to keeping him from retrieving the magic ring.
• Where Does He Get All Those Wonderful Toys?: Just like how the origin of their powers is never explained, it is left a mystery how the PJ Masks can have a high-tech HQ and personal vehicles.^note Or at least, the equipment they started with back in season 1. After PJ Robot joins the team in season 2, he can be seen building some new gadgets, so it can be assumed he created all the gear they gained from that point on The origin of the various tools used by the Nighttime villains (like Luna Girl's magnet and hoverboard and Night Ninja's Sticky Splats) also goes largely unexplained. At least with Romeo it can be handwaved that he builds them himself since he's a Child Prodigy / Mad Scientist, but that still leaves the question where he gets the raw materials to do so.
• Where the Hell Is Springfield?: The television version of Tarabiscoville where the heroes reside appears to be a mash-up of the French and North-American setting with a great influence of North American culture^note Both Halloween Episodes that shows the kids trick-or-treating, a tradition most prevalent in the US, Canada, Ireland and the UK, and during the Christmas Episode, it starts snowing. The episode Newton and the Ninjas also has it be in clear range of the Aurora Borealis, which is pretty close to the Arctic circle, meaning it could be in either Alaska or anywhere in Canada. To make matters more confusing, anytime the heroes are seen traveling into space from Earth or traveling back to Earth from space, they head for a different country or even entirely different continent (specifically in Europe, or South America). It also gets even more confusing with the Season 6 premiere episode "Heroes Everywhere" where, at the end of the episode, the beams of the heroes (Catboy, Owlette, Gekko, An Yu, Newton Star, and their new teammate Ice Cub) that form their new HQ, Power Q, come from Central Florida, suggesting that Tarabiscoville is possibly located in Florida, which is in the United States; but in other episodes like "Space Fairy Hero" and the four-part episode "Heroes of Iceworld" (the latter of which broadcasted earlier in the IP's native France, and in Mexico), when the characters travel back to Earth from space, they're shown heading to France, which is where Tarabiscoville is located in the books. Even still, Tarabiscoville's location consistency is all over the place throughout the show.
  • Averted in the books, where Tarabiscoville is located in Paris, a possible reference to said books being made in France.
