MARIONETTE

Origin as Follows:

Princess Mari of Homeworld was hiding from Baron Karza -- who had usurped the throne and murdered her parents -- and organizing a rebellion. She was aided by her robotic servant Microtron. She joined Commander Rann and Biotron -- Rann had spent a thousand years exploring the Microverse in suspended animation with Biotron as Pilot -- they formed the core of the new group of freedom fighters known as the Micronauts. Appeared in Micronauts #1 through #59 / Annual #1 and #2 (first series), Micronauts #1 through #20 (second Series) and X-Men/Micronauts #1 to #4 -- all by Marvel Comics.

The series were based upon the Mego toy collection of the same name from the mid-to-late 1970s -- Marionette was a NEW character created by Marvel, along with Commander Rann and "Bug".
