Nite Owl I was inspired by Dan Garrett, the original Blue Beetle, while Nite Owl II homages Ted Kord, the 2nd Blue Beetle.
Furthermore, the obvious resemblance of the costumes for both Nite Owl I and II to those of Robin and Batman respectively is reinforced upon watching the film. Other similarities have been drawn between Nite Owl II and Batman, namely that both are non-powered humans with vast amounts of wealth, and both rely on gadgets and training, rather than superpowers of any kind.
