* 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.
