10 Comic Book Supervillains Who Created Their Own Worst Enemy
4. Ultron And Vision
As far as comic book rivalries go, the one between Ultron and Vision is pretty poetic.
Just think about it: Hank Pym creates Ultron, who then rebels against his creator and resolves to destroy humanity. But just as Hank is initially defeated by his own creation, so too is Ultron when he creates Vision, an android with the body of the original Human Torch and the brainwave patterns of Wonder Man, a superhero who at the time was believed to be dead.
It doesn't take long at all for Vision to rebel against his android father (because you know, superhero brain and all that), which then leads to Ultron's first defeat.
Vision went on to become one of the most important members of the Avengers, and one who always rose to the challenge of defeating Ultron whenever he returned, determined to embrace humanity where his creator condemned it.
