Choujin Sentai Jetman :
Villains Footsoldiers 1991

The Grinam Soldiers are the pawns of the Vyram, who are ordered to fight the Jetman. They have black skin with orange and yellow blots over the entire body as well on their visors and are born from Grinam seeds. Their intelligence is very low, though some are able to speak. The distinct sound they make is an anonymous screech. The Grinam Soldiers are armed with axes and capable of launching explosive shells from their hands. In the Episode 28 they are voiced by Wataru Abe.
