Age: 3 years A shape-changing creature, his name (roughly, "sonic ball") is fairly descriptive. He is usually depicted as a round, yellow sphere with a face, variably with wings or arms, deep voice, and a loud temperament. Often, when getting emotional, he will transform into an extremely muscular full human body. In spite of being such a bizarre creature, he is for some reason the leader of Shinobu's ninja clan. Onsokumaru is perverted, lecherous, messy, loud, a cheat, and greedy. He imagines softcore-pornographic fantasies about Shinobu and Kaede, either for his own personal pleasure or to enthrall or persuade the male ninjas into helping him. On the other hand, he is often friendly, and has a silly playful side. (wikipedia)
