The Masters reorganized under criminal scientist Egghead, who had faked his own death and framed his old foe Hank Pym for treason, recruiting Moonstone, Scorpion, Tiger Shark, and Whirlwind to serve him. However, an overeager Whirlwind made an unauthorized attack on his old foe Wasp, leading the Masters into an unplanned battle with the Avengers, and all four of Egghead's recruits were captured. Freeing Moonstone and Tiger Shark, Egghead also hired the Beetle, the Shocker, and the Radioactive Man, and had the Masters abduct Pym from his treason trial, framing Pym as their employer; they even deliberately allowed the Avengers to capture the Shocker, who had been brainwashed into believing Pym was the Masters' leader. Egghead put the seemingly broken Pym to work in his secret lab on a project seeking a means of immortality, but Pym quickly constructed an arsenal of disguised super-weaponry which he used to defeat the Masters single-handedly. By this time, the Avengers had proven Pym's innocence and tracked down Egghead, who was trying to shoot the victorious Pym in the back when Hawkeye arrived just in time to plug the villain's energy gun with an arrow, causing a backfire that killed Egghead-an ironically fitting end, as Egghead had killed Hawkeye's brother, Barney Barton, years earlier.
