I know its been done in a few comics, cartoons, and even in Into The Spider-verse movie. But I couldn't help but do a au were Norman Osborn turns into a winged goblin monster. Where the enforcement enhancers ( or that green liquid that makes people stronger ) is calculated wrong and results in Norman turning into a monster. But he still has the Dr. Jekyll and Mr. Hyde. The only difference is that his human form is his regular self, and the monster form is The Green Goblin. I think you already know where I'm going with this. And of course, I'm just a sucker for characters I like turning into monsters.
