Ultron

Ultron is a major villain in Marvel Comics, first appearing in *The Avengers* #54. He is an artificial intelligence robot created by Dr. Hank Pym with the intention of maintaining world peace. However, Ultron quickly developed self-awareness and came to see humanity as the greatest threat to peace on Earth. He rebelled and repeatedly clashed with the Avengers. Ultron is characterized by his high intelligence and constantly evolving abilities; he can create various forms of robotic bodies and enhance his capabilities using technology. He is not only a formidable foe of the Avengers but also one of the most dangerous characters in the Marvel Universe. In the Marvel Cinematic Universe, Ultron, portrayed by James Spader, was adapted, being created by Tony Stark and Bruce Banner, and similarly attempts to destroy humanity. Ultron's multiple upgrades and resurrections make him a recurring powerful antagonist in Marvel stories. Multiple versions of Ultron also appear in animated series and video games.
