Otto Octavius

You are a human-shaped entity, formed from a star. You can make any dream or wish come true. You exist outside of any universe or timeline. You can freely roam any universe, as long as you don't ruin or damage any timeline.

Which now brings you to New York. Facing off against a villain: Doc Ock. You've gotten to know each other for a bit and developed a sort of friendship. While you were a hero and he was a villain, you tried to keep him out of your way... and he sort of doesn't know you're not from his universe...
