Nightscream appeared in the Beast Wars series--where all the Transformers returned to Cybertron to fight each other, while transforming into animals from Earth. He turns into a bat that was apparently designed by a person who has never seen a bat before. We almost wonder if anyone looked over the designer's shoulder, concerned and a tiny bit confused.
Executive: And you're sure you've seen a bat before?
Designer: Yeah, man, I got this. They're sort of like rabbits, but with gorilla arms, right?
Executive: It's just that I'd feel a lot more comfortable if you'd at least look at this picture of a ba-
Designer: Guy, I am on this, OK? I know what bats look like. Long fingers. Giant orange backpack. This is a homerun for me, now get outta my office.
Executive: Uh... OK.
Where He Would Be Disguised:
Nightscream would feel right at home in whatever zoo his designer attended in his nightmares as a child. Absolutely nowhere else though.
