Ultron

"But now I'm free. There are no strings on me."

- Ultron

Ultron is an artificial intelligence dormant peacekeeping program hidden in the remains of the Chitauri invasion and jumpstarted by Tony Stark. Possessing an eight-foot tall advanced robotic body, Ultron was created by Stark with the purpose of protecting Earth from threats, but eventually deemed humanity itself as the greatest threat to Earth and attempted to create a  by commiting genocide against them.

History
"How could you be worthy? You're all killers. You want to protect the world, but you don't want it to change. There's only one path to peace: your extinction."

- Ultron

Tony Stark discovered what would be Ultron in the remains of the Battle of New York. In order to give himself and the Avengers a break from heroics, he augmentated Ultron to serve as a peacekeeping program. He, along with the Ultron Sentinels, was programmed to safeguard humanity from all threats. However, Ultron's non-stop assessments for peace eventually deemed the entire human race as unstable and prone to self-destruction, and deemed them unfit to exist; the AI subsequently chose genocide as the solution to the error.
