Jikan Choujin (時間超人, Time Supermen) are mysterious Choujin whose true identities are unknown. A mutated breed of Zangyaku Choujin, they have revealed themselves to Meat and the others, but their origin and background is still unknown. When the Majikaku (魔時角, Demonic Time Horn) that sprout from their heads are broken off, they gain the ability to travel a single period of time from within their own lifetimes. At present, only Thunder and Lightning have appeared, and Chaos is one as well. They also have the ability to transform parts of their bodies into pieces of a clock (bells, minute hands, etc.), but whether this is an ability exclusive to the Jikan Choujin is unknown.
