4. Hector Hammond

Hector Hammond was a career criminal on the run from the law near Coast City, California, when he stumbled across a meteor fallen from the heavens. The meteor exuded a radiation that "propelled everyone affected by it forward 100,000 years into the future evolutionarily".

He used it to mutate a group of scientists into future-men, and he sicced them on Green Lantern. After that failed, he irradiated himself and"¦got a really large head. He got telepathy too, but the more important part was the whole "can't stand or walk because he is a literal bobblehead" part. So that's what to expect out of the next hundred thousand years of evolution, huh? We'll all get massive heads and be able to read each others' minds? I am very glad I won't live to see that future; that sounds terrible.

Hammond is also immortal, by the way. He decided to blast himself with the meteor again, because that sounds like a GREAT idea. Just the best. How could that go wrong?

Have fun trapped in a immobile sadness-body you can never escape from, Hector. Real smart decisions there.
