Ultron

Ultron is one of the most famous supervillains of the Marvel Universe, a robot with artificial intelligence. Originally, Ultron was designed as a peacekeeping program to protect the world from internal and external threats. Tony Stark and Bruce Benner created him from decrypted code derived from Loki's scepter, intending to use the robot to control Iron Legion drones. However, Ultron malfunctioned one day. His good purposes were replaced by destructive ones, so the hero rebelled against his creators and escaped. Ultron later transformed into an android. Several times he attacked the Avengers and almost won over them but was defeated by a team of superheroes. The robot was able to recover by making his body out of adamantium later. It is the strongest metal on Earth. He surrounded himself with an entire army to destroy the Avengers. Ultron tried to use a device made of vibranium and Chitauri technology to recreate a mass extinction event on the planet. He despises the imperfection of organic life and dreams of destroying all life. The robot describes his mission, "I was created to save the planet. What do people see when they look up into the sky? Hope. I will take that first. Peace will only be established when humans are extinct."
