At Berchtesgaden, the captive Invaders
come face to face with their captor, Der Fuehrer Adolf Hitler
himself. He speaks to them using a translator invented by the late
genius Brain Drain, who also created the formula that gave Master Man
his power. Captain America notices that Hitler is holding a copy of
MAJOR VICTORY comic book by the imprisoned GI Biljo White, and tries
to get him to reveal its importance. Hitler doesn't fall for the
trick and leaves with Master Man and Sub-Mariner trading threats....
Elsewhere in the castle, Madame Ratsel
(“Mystery”), who had captured the American disguised as his
girlfriend Julia, now presides over his brutal interrogation. She
wants to learn what he knows about the Super-Soldier Serum he
mentions in his comic book but Biljo White denies knowing anything,
having only used a phrase that was going around as a rumor. She
hypnotizes him, which leads him to reveal he did know a scientist on
the Super-Soldier project who mentioned Potassium as a key
ingredient. Elated, she rushes to her lab to add the chemical to
Brain Drain's formula which created Master Man. She intends to test
the new formula on herself, wanting to prove superior to the men she
despises. A quarrel with another officer leads to an explosion and
Ratsel, enveloped in a gas, suddenly grows more powerful. The
Invaders, hearing the explosion elsewhere in the castle, manage to
escape their bonds and battle the Nazis; Namor and Master Man do
battle while the Human Torch and Toro pursue Hitler. They have Der
Fuehrer cornered when Madame Ratsel, now called Warrior Woman, blasts
them with a fire hose and then punches them out. She dashes to the
main fight and decks Bucky with a single blow, then picks up Cap and
hurls him from the battlements. She and Master Man together take down
Namor as Hitler gloats, ordering the four remaining Invaders (they
assume Cap is dead) taken to Berlin where they will be publicly
executed....
