Avengers #68 (483) 2003

Avengers #68, published by Marvel in September 1969, concludes a pivotal Ultron storyline. In "And We Battle for the Earth!", the Avengers, including Black Panther, Vision, and Thor, confront Ultron-6, who seeks to devastate New York. The Vision initially thwarts Ultron's nuclear plot. Ultron then kidnaps Dr. Myron MacLain, aiming to create a robot army, leading to a showdown at the United Nations. Hank Pym, disguised as MacLain, tricks Ultron into absorbing a pacifist command, causing the robot to overload and be contained. This issue features Ultron's appearance as "The Ultimate Ultron" and a clever defeat orchestrated by Hank Pym.
