Jaken
His name means "evil sight"
English voice: Don Brown
Japanese voice: Yuichi Nagashima

Jaken has no known family, but he was once the leader of a small group of .. whatever he is. Then he met Sesshomaru and was so amazed by his power that he has followed him ever since.

Jaken's power lies in his Nintoujou (staff of heads). This two headed staff has the power to shoot both fire and water. It can also be used to detect things, and possibly more uses which are not yet revealed. He often rides on the two-headed dragon Ah-Un.

As the servant of Sesshomaru, Jaken follows him around everywhere and eventually even becomes friends with Rin. He is always trying to do things to please Sesshomaru, and he rarely succeeds. He is quite a bothersome character and it is amazing that Sesshomaru puts up with him.
