9. IQ

Hi, everyone, meet Ira Quimby. Quimby was kind of a moron, and kept suggesting dumb crime ideas to his criminal bros, so they ironically nicknamed him IQ. You know, because criminals are jerkfaces.

One day, Quimby figured out a way to get one of his weird plans to work and became a gadget-wielding supervillain. And of course, he took his newfound skills and took to the skies to challenge a hero worthy of his might. The only hero on his playing field. Who was that hero? The one, the only, Hawkman!

Yep, Hawkman. That raving, stalking, screamy, medieval, weapon-wielding lunatic. Hawkman discovered that it was an alien artifact that made IQ smart enough to pull off his capers and caught the guy for good. In fairness, getting hit in the skull with a mace a couple of times probably reduced his intelligence quite a bit. But I do think it's appropriate that one of Hawkman's most prevalent villains is a dude ironically nicknamed IQ.

IQ was eventually locked up in a maximum security prison which"¦uh"¦seems like overkill, maybe? Just a tad?
