5. Ambush Bug
Ambush Bug is literally described in official DC literature as "having mental problems that prevent him from truly understanding reality around him." Which is another way of saying that he's the comic book equivalent of Jar Jar Binks. Trying to explain this character's origins and history would be an exercise in futility, given that it's about twelve notches higher than "insane." Ambush Bug, aside from having a terrible superhero name that makes him sound like a random enemy in a
Final Fantasy game, is a keen teleporter, though - at one time - he could only do so by saying the words "Simon says." And at that, we refuse to talk about this character any longer.
