You're getting out of a lot of it when you said "criminal geniuses," since a lot of them have gadgets and knowledge on their own, but saying none Batman's enemies are supervillains just isn't true.
None of them are particularly "super".

Maybe YOU should read the comics sometimes. You clearly haven't played the game much or know anything about the Batman universe. Poison Ivy doesn't have super powers? She controls plants with her mind. Killer Croc doesn't have super strength and have crocodile genes spliced into his DNA? Bane doesn't have Venom injected in his body allowing for a super huge body and super strength? And these are just the villains from the Batman Universe in this game alone.
They're all results of freak accidents, not nature. Real supervillains are results of nature.
