Egghead then sent his Masters of Evil to kidnap Pym from his own trial, making it appear as if Pym himself had staged a rescue. The attempt was successful and Egghead instructed Pym to construct an anti-aging device. Subsequently, Pym goaded Egghead into letting him test the machine himself. However, the device turned out to be a weapon system, and he single-handedly defeated the assembled Masters of Evil. The Avengers arrived too late to be of assistance, but Hawkeye arrived at the laboratory in time to see the defeated Egghead about to shoot Hank in the back out of spite with his energy blaster. Hawkeye shot an arrow into Egghead's gun barrel. The gun misfired, causing an accidental explosion of the energy blaster which killed Egghead instantly, with Hawkeye avenging the death of his brother Barney Barton at Egghead's hands years ago. Days later, his ashes were scattered by Pym and Trish in a private ceremony.
