Looking back at the most defining moments of Otto Octavious' career as Spider-Man
2. Peter's "Final" Defeat ("Superior Spider-Man"#9)
When Ock realized that Peter was along for the mental ride, the mastermind villain-turned-hero did something about it. Confronting each other in their shared mindscape, the two mortal enemies went to battle over who would control the body of Spider-Man. They each pulled out all the stops, with the mentally-conjured images of Peter's allies and friends ganging up on Ock to kick him out of Peter's mind, but Ock countered with the memories of Peter's greatest villains. It appeared as if Peter had the upper hand, but when Ock began pointing out Peter's failures, Parker's resolve began to weaken. He pointed out how Peter thought everything was a joke -- and Peter blinked. Ock showed Peter how his failure to kill Massacre cost innocent lives -- and Peter balked. And when Ock pointed out how Peter tried to prevent Ock from helping Amy Chen, a true innocent, Peter was defeated.
It was only for a second, but Peter's selfish attempt at stopping Ock from living up to a hero's responsibilities gave Otto the edge he needed to remove Peter from his mind, this time for good. In this mental battle, Ock proved himself to be superior by finding and exploiting the one second of true selfishness Peter had committed since he failed to stop a burglar years ago. Peter was gone and fans were left shocked and numb.
