9. Hector Hammond (Green Lantern)
After being summoned by his father, Senator Robert Hammond, to a secret government facility, eccentric scientist Hector Hammond performs an autopsy on Abin Sur's body (Abin Sur being the dying alien who crash-landed on Earth and commanded his ring to find a replacement wearer - Hal Jordan). A piece of Parallax, a dangerous cosmic being powered by fear, inside Abin Sur's corpse enters Hammond giving him telepathic and telekinetic powers at the cost of his sanity. His head also grows more and more deformed as the size of his brain increases, eventually forming a huge bulbous mass, as Hammond becomes the secondary villain of the movie - attempting to bring a helicopter down, killing his Father and attacking Hal's love interest Carol Ferris, before being consumed by Parallax, the very entity that made him how he was.
