Half-Man was a ruthless, Nazi, cyborg, whose left side, after being shot down in a dogfight by the hero Skywolf, was completely replaced by steel, robotic parts. He reported directly to Adolf Hitler. At one point, he was abducted by the Heap, who enjoyed the fact he spoke German (though the beast had clearly lost the ability to understand his actual words). Von Tundra managed to escape both death and capture on several occasions, ultimately, however, being brought to justice.
