* ActorAllusion: In "Plus One", Mayor Luskey remarks "This is why I hate nature", which is an apparent play on Carmine Fanzone's catch phrase of "This is why I hate machines" from ''WesternAnimation/TransformersAnimated''. Both Luskey and Fanzone were voiced by Creator/JeffBennett.
* TheOtherDarrin: Because of his stroke, Creator/TimCurry was replaced by Creator/GregEllis as Dr. Morocco.
* NamesTheSame: This isn't [[WesternAnimation/BatmanTheBraveAndTheBold the first time]] Creator/SteveBlum's voiced a character calling himself [[Franchise/TheFlash Heatwave (or Heat Wave)]]. [[spoiler: [[RoleReprisal Nor]] [[CompositeCharacter technically]] [[CastingGag would it be]] [[Series/LegendsOfTomorrow the last]].]]
* PlayingAgainstType:
** Creator/SteveBlum as Heatwave.
** Creator/DCDouglas as Chase.
** [[spoiler: Jules Verne]] is probably ''even more'' against type for Creator/DiedrichBader than {{WesternAnimation/Batman|TheBraveAndTheBold}} was.
* RecycledScript:
** The plot for the episode "Enemy Of My Enemy" shares similarities with The Miles From Tomorrowland episode "Unexpected Ally". Both episodes involve the protagonist temporarily teaming up with an enemy to catch a more dangerous enemy. Both episodes were also written by Nicole Dubuc.
