Top 12 Avengers-Number 8

Vision

At some point during the writing of the Avengers, someone came up with a crazy idea. (In this case, I'm talking about the writing staff right now.) They thought it might be a good idea to make an character that was an android to explore some unique ideas. That is when the Vision was created. Even with an idea, someone has to make that idea work. So the writers started exploring possibilities, looking for ideas that could lead to stories that would draw the readers. (Isn't this the eternal goal of comic book writers?)

Vision was originally created by Ultron in a plot to destroy his own creator, Henry Pym. The sythezoid was given the brain patterns of Simon Williams (aka Wonder Man) who was still believed to be dead. This was an error on Ultron's part since he didn't know that Wonder Man had died his first death as a hero.

Vision had several occasions where he betrayed the Avengers because of his robotic nature. He built Ultron an adamantium body, and driven a bit unstable by losing his body in a fight with Annihilus, Vision tries to take over all of the computers in the world in order to make the world a better place.

Vision develops a relationship with Wanda Maximoff (aka Scarlett Witch) and unconsciously using her hex powers, Wanda enables the couple to have a pair of twins. This relationship causes lots of trouble though, because of Wonder Man's brain patterns. Because Vision is basically Wonder Man, Simon also falls in love with Wanda creating an awkward love triangle.

Although he has had many set backs, Vision is a capable hero who brings a lot to any team he joins. He has super-human strength and the ability to fly, but the most important ability is being able to alter the density of his body. Vision can calculate at amazing speeds, and does not need to sleep so he can handle extended missions.
