Selected from the most vicious and evil of Kuro Juujigun's ranks, the Masked Monsters (仮面怪人, Kamen Kaijin?) have been surgically enhanced with a variety of weapons and abilities. Most sport hideous "masks" that are the source of their powers. Others carry elaborate weaponry that they can use against the Goranger team. All were cyborgs with some having been further empowered with supernatural abilities.
