The android Ultron was created by Henry Pym, based on Pym's own brain patterns, and was intended to serve him. Ultron gained sentience and rebelled, seeming to instantly demonstrate an Oedipus Complex, where he felt irrational hatred for his "father" Hank, and demonstrated a frightening interest in Hank's lover Janet van Dyne, a.k.a. The Wasp. Ultron then hypnotised Pym into forgetting his existence and disappeared. Forming a plan to blackmail New York City and destroy the Avengers, Ultron-5 adopted the identity of the Crimson Cowl and recruited Klaw, The Melter, The Black Knight, Whirlwind and The Radioactive Man to carry out his scheme. The team became the second to be dubbed the Masters of Evil.
The new Masters Of Evil are gathered.
With Jarvis under his control, Ultron adopted the identity of the mysterious Crimson Cowl and set about freeing members of the first Masters of Evil from their prison cells. As the Cowl he also secured the services of the Wasp’s driver, secretly the villain Whirlwind and also sent an offer of membership to the original Black Knight, not realising that he had been replaced by his heroic nephew Dane Whitman.

Having defeated the Avengers the Masters opened a channel to the Crimson Cowl to present their captives, and the Cowl was unmasked as a robot, but the Avengers and Masters were made to believe this was only a decoy, as the "real" Crimson Cowl unmasked himself as Jarvis.
Ultron twists Jarvis's mind!
Ultron sought out the Avengers' butler Edwin Jarvis and used his encephalo-beam to twist his mind, making him believe the Avengers would not help him pay for his mother's medical bills. Ultron then offered Jarvis the money providing he provided the Masters of Evil with the new security plans to Avengers Mansion.
