Iron Man #5 2021

Iron Man #5 (1968) transports an unarmored Tony Stark to the 24th century, where he faces execution. He is accused of creating Cerebrus, a supercomputer that later enslaved humanity. With the help of a rebel named Krylla, Tony escapes and discovers a preserved Iron Man suit in a future museum. He must then don his iconic armor to battle the sentient Cerebrus, hoping to prevent the dystopian future. This Silver Age issue is notable for its unique time-travel narrative and the first appearance of the powerful artificial intelligence, Cerebrus.
