Ultron is the main antagonist of Avengers: Age of Ultron.

Avengers: Age of Ultron

Ultron appears as a messed up starter version of Ultron, which creeps the Avengers and their allies into battling him. He eventually grows stronger and stronger, upgrading himself to become a worthy opponent to Earth's Mightiest Heroes. He creates an army of Ultron Sentinels and uses twins Quicksilver and Scarlet Witch to bring rise to human extinction.
