The original Master Man (Wilhelm Lohmer) first appears in the title Giant-Size The Invaders #1 (June 1975) and was created by Roy Thomas and Frank Robbins.

[2] The character reappears in a two part story in the title Marvel Two-In-One, and with Nazi allies Brain Drain, U-Man and Skyshark plans to sabotage New York City with a new super weapon.

During the course of a multi-issue storyline involving the Invaders' incarceration and eventual escape from a prison in the German city of Berlin, Master Man meets Julia Koenig, who courtesy of an accident gains abilities similar to his own and becomes the Nazi heroine Warrior Woman.

[8] It is revealed in flashback in the title Namor the Sub-Mariner that near the end of World War II, Baron Strucker placed Master Man and Warrior Woman in suspended animation in a hidden laboratory, thereby "preserving" the Nazi dream for use at a later time.

When Namor the Sub-Mariner, former founding member of the Invaders, finds the laboratory, he battles Master Man, until the Nazi loses his abilities and reverts to Wilhelm Lohmer.

The Nazi version of the process is amplified and as a result Lohmer receives greater abilities than those of Captain America, including superior strength, stamina, durability, speed, and flight.

In the Heroes Reborn universe, a version of Master Man named Alexander appears as a super-powered ally to the Red Skull promoting Nazism in the present day, and is seen attacking Nick Fury (and is revealed as an LMD).
