confidence of the Avengers with a ruse and was duped by the villain Egghead, Pym was jailed. Pym would later outwit Egghead and defeated the latest incarnation of the Masters of Evil single-handedly, and proved his innocence. Pym reconciled with the Wasp, but they decided to remain apart. Pym retired from super-heroics, but returned years later. This was followed by several major storylines, such as "Ultimate Vision" in which the Vision took over the world's computer systems in a misguided attempt to create world peace; the formation of the West Coast Avengers; and "Avengers Under Siege" which involved the second Baron Zemo and the Masters of Evil taking over the mansion and severely injuring Jarvis and Hercules. "Assault on Olympus" featured Hercules' father, Zeus, blaming the Avengers for his son's injuries and brought them to Olympus for trial, and the "Heavy Metal" arc saw the Super Adaptoid organized several robotic villains for an assault on the team. New members during the 1980s included Tigra; the She-Hulk; Monica Rambeau (then going by the name Captain Marvel); Starfox (the brother of Thanos); Hawkeye's wife, Mockingbird; and Namor, while Henry Pym emerged from retirement to join the West Coast Avengers. Spider-Man was again offered membership, but failed to gain admission due to security concerns by the Avengers' government liaison. The villain Nebula falsely claimed to be the granddaughter of Thanos. The team relocated for a period to a floating island off the coast of New York called Hydrobase after Avengers Mansion was severely damaged during the events in "Under Siege". Hydrobase was later sunk during the Acts of Vengeance crossover. The Avengers and West Coast Avengers changed to allow members to be active when available and reserved when not available and merged the two separate Avengers teams into one team with two bases. The Vision had his personality fundamentally altered, along with the discovery that the children of the Scarlet Witch and the Vision were actually illusions. The loss of the Scarlet Witch's children and the Vision, who was disassembled by government agents in retaliation for the Ultimate Vision storyline, drove her insane, although she eventually recovered and rejoined the team. This story revealed that the Scarlet Witch's powers included wide-range reality manipulation and she was what the time-traveling Immortus refers to as a "nexus being" setting the stage for 2004's eventual Chaos and Avengers Disassembled storylines.
