1960s
Although Ultron first appears in Avengers #54 (1968), the character is disguised for the majority of the issue as the "Crimson Cowl," with his face only revealed on the last page of the issue and no name given to the character. The character leads the Masters of Evil against the Avengers, having hypnotized Edwin Jarvis into working for him. In the following issue Avengers #55 (August 1968), the character is identified as Ultron-5, The Living Automaton. In Avengers #57–58 (October–November 1968), a flashback sequence revealed that Ultron created the "synthezoid" Vision as a weapon to destroy the Avengers. The Vision—having Wonder Man's brain patterns—destroys Ultron with the Avengers' aid.

Further flashbacks reveal that Ultron is Hank Pym's creation, and is based on Pym's brain patterns. The robot gradually developed its own intelligence and rebelled, and almost immediately develops an Oedipus complex, whereby it feels irrational hatred for Hank, and demonstrates an interest in the Wasp (Janet van Dyne). Rebuilding itself, learning how to turn itself on, and upgrading five times, Ultron then hypnotizes and brainwashes his "father" into forgetting that the robot had ever existed.

The character's next appearance is in Avengers #66–68 (July–September 1969), where the character, now referring to itself as Ultron-6, uses the fictional alloy adamantium (the first appearance of the substance in Marvel Comics' publication history to upgrade his body to an almost indestructible state and takes the new name Ultimate Ultron. His plans to destroy humanity are again thwarted by the Avengers.
