The Avengers #83

Regular Edition

Valkyrie shows up at Avengers HQ and convinces Wasp and the Scarlet Witch to join her team of Lady Liberators. With the male members of the Avengers attending Tom Fagan's Halloween parade, the Masters of Evil attack and pummel our heroes. The Lady Liberators show up to save the day and do what their male chauvinist pig counterparts failed to do as they make quick work of the villains. Valkyrie is revealed to be the Enchantress, however, and the lady heroes are forced to defeat their former leader. The gender war rages on.
