Jimmers are the robotic soldiers of Armed Brain Army Volt and antagonists in Chojuu Sentai Liveman.
Chojuu Sentai Liveman
In episode four, Doctor Mazenda creates a new type of Jimmer called "Dummy Man" that is capable of disguising itself as human.
In one notable instance, in episode 13 a "Dummy Man" Jimmer went haywire after being exposed to the poison gas Volt was developing and broke free of Volt. After escaping, the rogue Dummy Man was found by Megumi and Colon and taken in by them. The Jimmer ended up falling in love with Colon and ultimately sacrificed itself to save Colon from Volt's Poison Gas Brain
Kaizoku Sentai Gokaiger: The Flying Ghost Ship
Several Jimmers were part of an army of past enemy grunts that were fought by the Gokaigers in Los Dark's ghost dimension which housed the 1500 spirits of the villains defeated by the Super Sentai. After losing some of their number in an initial skirmish, the Jimmers merged with the other remaining grunts to form the Combined Combatant. Though the stronger opponent, the Combined Combatant proved to be unstable due to internal conflicting among the grunts composing him over who got to finish the pirates off. Taking advantage of this, the Gokaigers used the Battle Fever J Ranger Keys to destroy the Combined Combatant with the Penta Force cannon.
