Harrison Thompson (Earth-1600)

Harrison Thompson (a.k.a. the Gray Goblin) is Flash Thompson's alcoholic father who often beated up everyone in his family besides his son. He died of liver disease, but was later resurrected by Doctor Octopus using a goblin serum fused with Venom's DNA, turning him into a giant, bulking, gray-skinned goblin and was seduced into trying to kill Agent Venom after he learned that is was his own son, Flash.
