|This article is about a/an army of grunts in Taiyo Sentai Sun Vulcan.|
Machinemen are grunts in black with the red insignia of Black Magma on their faces. They are armed with a trident-like knife, a machine gun, grenades, and sometimes a bazooka.
Several Machinemen 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 remaining members from each grunt group merged 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, the Gokaigers used the Battle Fever J Ranger Keys to destroy the Combined Combatant with the Penta Force cannon.
- Machinemen's motif is the one of Kumadori, the stage makeup worn by kabuki actors
- Although this series was associated with Marvel Comics, the Machinemen bare no connection or relation to the Marvel character known as "Machine Man" (also known as "X-51" and "Abel Stack")
