Hector Hammond

A small-time schemer who discovered a meteor fragment that accelerated his brain's evolution, Hector Hammond gained vast telepathic and telekinetic powers at the cost of a grotesquely enlarged skull and total physical paralysis — becoming one of Green Lantern Hal Jordan's most persistent enemies.

Few villains in DC's Silver Age canon feel quite as unsettling as Hector Hammond, who slithered onto the scene in 1962's Justice League of America #14, conjured by the legendary team of Gardner Fox and Mike Sekowsky. A fixture of the Green Lantern corner of the DC Universe, Hammond has kept extraordinarily dangerous company across six-plus decades — sharing pages with Hal Jordan, Superman, Bruce Wayne, and The Flash — cementing his place as a recurring thorn in the side of some of DC's mightiest heroes. His appearances across Green Lantern, Justice League of America, and The Green Lantern Corps speak to a villain with genuine staying power, one the writers keep returning to when they want something genuinely creepy on the page. If you're exploring the weird, cerebral dark side of Silver Age DC storytelling, Hammond is absolutely worth tracking down.
