Nels Van Adder
It was revealed that soon after Norman had Stromm arrested for embezzlement, he had found only a portion of the notes detailing his partner's serum. Norman tests the incomplete version of the serum on an Oscorp employee named Nels Van Adder, driving Van Adder slowly insane and beginning his transformation into a red, demon-like being known as the "Proto-Goblin". Killing several people and blaming Norman for what has happened to him, Adder proceeds to harass and later attempts to kill him before being knocked out a window in Oscorp by Arthur and George Stacy and fleeing into the wild. In order to escape conviction for what he had done to Van Adder, Norman convinces the police that Van Adder had been experimenting on himself, and that he had secretly been trying to help him. Van Adder's current fate remains unrevealed.
As well as endowing Adder with super strength and agility, the Goblin Serum also gave him large claws, talons, fangs, glowing green eyes, and near impenetrable skin (capable of withstanding several close range bullet shots).

However, his power was no match for his enthusiasm - he never even bothered to use the strength-enhancing formulas on himself, seemingly believing that just being the Green Goblin would enable him to defeat Spider-Man-, and, despite an elaborate plot to kill Silvermane, the underpowered amateur is confronted by Harry Osborn who has resumed the Goblin identity to stop him. They battle and Hamilton is accidentally killed by a bomb with which he meant to kill Spider-Man, and Harry becomes amnesiac.Years later there was speculation that Hamilton was the Hobgoblin but this is disproved.
