- Actor Allusion: Phil LaMarr, who voiced Static in the DCAU, voices Maxie Zeus here.
- Adaptational Intelligence: Zeus, compared to his comics and Batman: The Animated Series counterparts, suffers no A God Am I delusions and is thus scarily competent throughout the episode.

At first, they seem to be sarcastic, assuming it's standard issues, but eventually they become convinced someone is there and start looking for their gremlin in earnest.
- Offscreen Villain Dark Matter: How was Maximillian Zeus able to construct his flying airship and launch it without anyone noticing until he announced himself?
- Precision Crash: After the airship is badly damaged while Batman and Zeus were fighting, Batgirl has to take the damaged controls and steer the ship away so it didn't hit the city. Fortunately, she manages to direct it harmlessly to the bay in time.Zeus: (Awaking after being knocked out by Batman) The New Olympius?
