Ultron (Marvel Legends)
"Created by Hank Pym as an experiment in artificial intelligence, Ultron evolved farther and faster than its inventor had dared even dream. Retreating after a first, failed attempt to kill its creator, the robot rebuilt and improved itself, initiating a continuing pattern of modifications and upgrades. Ultron later attacked the Avengers, because of their connection to Pym, touching off a years-long succession of battles. Seeking its goal of digital domination with cold, computer-like determination, Ultron is a constant, unwavering threat to Pym, the Avengers and every other living being on the planet. Features 29 points of articulation, and includes a 32 page comic book, character-dedicated vehicle and an exclusive Marvel vs. System trading card."
