Jūgo's Clan

This clan is an unknown family, who originate from an unknown area. The members of this clan possess the innate ability to absorb from their surroundings due to a special body. Adversely, the sudden and uncontrollable surges of power resulting as a chronic effect of this energy, caused them to sporadically go berserk.

The only known member is Jūgo, who was said to have voluntarily gone to Orochimaru in the hopes that he could be cured of his fits of rage. According to Kabuto Yakushi, Orochimaru's subsequent investigations allowed him to discover the origin of the clan's power at the Ryūchi Cave, but he was unable to completely obtain the ability himself as his body couldn't withstand it.
