Avengers #228 (1982 Newsstand) - Marvel Comics

"Trial and Error!" While both the Avengers and the general public anxiously await the outcome of Hank Pym's trial for treason, Egghead again reforms the Masters of Evil and sends them to the courthouse to free Hank. During the resultant battle with the Avengers, the newly recruited Radioactive Man unleashes a gamma-ray burst which changes the She-Hulk back to Jennifer Walters, thus turning the tide in his allies' favor. Despite the heroes' best efforts, their opponents succeed in spiriting Hank away while deliberately leaving behind a brainwashed Shocker to assert that the former Avenger planned his own escape. Now believing that he can never be cleared, the captive Hank is seemingly coerced into aiding Egghead's latest scheme.
