Powers and AbilitiesEdit
Six Arms' most prominent ability is his super strength, being able to lift several times his own weight, punch through various resilient materials. His strength allows him to use anything heavy as a weapon, from big rocks he can throw several feet away to beams and pillars that can be used as clubs. Six Arms can create strong shockwaves by clapping all four of his hands together or slaming his fists on the ground. Six Arms can jump several times his own height. Six Arms has high durability, being almost fire and laser-proof.
Sometimes Six Arms' bulk is a disadvantage; all the extra muscle mass makes him relatively slow, and his size, likewise, makes using things designed for smaller species difficult. When under the effects of a cold, Six Arms' strength and stamina are weakened, he develops pungent hives in his armpits, and his skin color turns a darker shade of red.
