Medium Fighters Mukimukiman (ムキムキマン Mukimukiman?) and Fuufuuchu (フーフーチュウ Fuufuuchu?) are half-naked, comical wrestling rejects. Mukimukiman has a muscular build and is dressed in white battle gear with white hair; Fuufuuchu is obese and wears a large black helmet and red vest. In the first episode, they fight Metalder during his first battle and are pummeled and tossed aside. Their final appearance is in episode 8, where they are seen arm-wrestling with Hedogross.
