Baron Karza was the chief villain of the Micronauts, a dread knight clad in black with red highlights. A Magno-powered figure, he stood 8" tall, towering over the average 3 3/4" Micronauts. His body fired a small hard-tipped red missile, his fists also fired as projectiles, and he wore a jet pack with two formidable-looking red spears on top. Most importantly, his head, arms and legs were held to his body by magnets, allowing unusual articulation and recombination possibilities. Most notably, he could combine with his steed, Andromeda to become a centaur.
He also could be combined with his nemesis, the Force Commander, who was released that same year.
