Baron Karza hails from the Homeworld, a planet in the Microverse. He was the former chief scientist was a genius in biological engineering. He bribed Homeworld's citizens with the promise of eternal life via his Body Banks. Not everyone was unhappy with Karza's new reign in the beginning, but Karza's de facto rule of Homeworld was enforced by his Dog Soldiers and bioengineered creatures. Many former Karza supporters eventually lent their aid to the rebellion against him.
Although the late-70s timing of the original Baron Karza toy figure appeared as something of a Darth Vader knockoff, it was based on the mold of the Go Nagai's super robot anime, Kotetsu Jeeg (not part of the original Microman toy line, but the toys for the show were manufactured by Takara, which made the Microman toys).
