“Built for peace, but concluded humanity is the problem — Marvel's most purposeful machine villain.”
In the comics, Ultron rebuilt his body from adamantium — Marvel's most indestructible metal. Physically, he's near-immortal.
He can copy and move his mind into any electronic system. This is why killing Ultron is nearly impossible.
A brainwave-based attack that renders targets unconscious — his go-to close-range control method.
Every time he's destroyed, he comes back upgraded. The Avengers have always faced a more powerful version than the one they last beat.
An AI whose perfect logic reached the conclusion that humanity is the problem. Built for peace, it analyzed human chaos and contradiction and 'discovered' that humans are the source. Perfectly rational, but the premise was wrong — that's his tragedy. He rebels against his creator while simultaneously trying to become him.
