Throughout his career, Spider-Man had been antagonized by a gruesome gallery of fearsome foes, but no one had quite reached the pinnacle of perversity that Norman had!

As Peter Parker struggled with his increasingly serious blackouts, the outline of Osborn's most indidious plan ever came into focus: he had put a special potion in Peter's toothpaste, that was affecting him, forcing him to wear the goblin uniform and attack his own friends.

When he realized what was happening, he was captured by Norman Osborn and took to the Osborn estate.

Showing how insane he was, Norman tried to convince Peter Parker to join him in the darkness of his world. He intended to transform Peter into a real heir for the Osborn legacy.

Peter Parker strove to overcome every obstacle placed in his way to at last face his hated arch-enemy. And Spider-Man had to struggle with every fiber of his being to avoid the greatest triumph of Norman Osborn.

Eventually, Peter could be able to fight the Green Goblin phisically, forcing him to abandon the place, after he changed his mind about having Peter as his heir.

It was a desperate descent into madness from which neither Spider-Man nor the Green Goblin emerged unscathed.
