10 Insane Times Supervillains Developed New Powers
4. Ultron - Literally All The Time
Ultron is another of those Marvel villains who just keeps adapting. They're one of the Avengers' most iconic antagonists and has shown up to screw with the fabric of reality more times than Kang the Conquerer.
Created by Hank Pym during his not so heroic years, Ultron boasts an adamantium shell that is near indestructible. They're super-strong, capable of flight, has lasers for eyes, and can even put their enemies in a coma if they so choose.
Point being, the basic Ultron is already a massive challenge. The major dilemma for the Avengers is that, every time Ultron 'dies', he always tends to come back stronger. He even survived as radiowaves in space - so impervious is he to perma-death - and managed to conquer the world completely during the events of Age of Ultron.
