He's been sent by Ultron to destroy the Avengers, but can an artificial man find the strength to turn against his maker? One of the most stalwart assemblers Earth's Mightiest Heroes have ever known makes his debut right here, and the team will never be the same. It's one of the all-time great Marvel comic books, boldly re-presented in its original form, ads and all! Reprinting AVENGERS (1963) #57. All Ages
