Vision
Humans are odd. They think order and chaos are somehow opposites and try to control what won't be. But there is grace in their failings. I think you missed that.

Vision is a synthezoid created by Ultron in an attempt to create a more powerful body. He was turned into the heroic Vision by the Avengers and was able to help them stop Ultron.
History[]
Origin[]
Vision was originally created by Ultron in an attempt to create a more powerful body, along with a mind-controlled Helen Cho, through a combination of synthetic tissue and vibranium. Knowing the body would make Ultron unstoppable, the Avengers stole it while Ultron was half way through downloading his program to the body.
