Amazing Spider-Man #30: Skottie Young Variant

Despite the injection of Goblin's serum, Norman does not go back to being as before, because he has now learned to control it. Since the tentacles know where Norman is, Spider-Man knows too, but he and Jonah realize that keeping them on him makes him behave like Otto and therefore he must get rid of them quickly. Spidey reaches Doc Ock before he can kill Norman and he becomes enraged when he sees that he is using his old arms. The battle is balanced, but the spider behaves more and more like Otto. He and Norman overpower the latter, but after coming close to killing him, Spider-Man removes his tentacles and Doctor Octopus eventually escapes.
