Enma

Overview
Enma the Monkey King was the personal summon of Mukai Uzumaki, the Third Firudokage. He is a long-time companion of Mukai, implying that he himself, is also rather old. Enma was fiercely loyal to Mukai, although he didn't always approve of his actions. Enma's body and tail is covered by white fur which protrude from his sleeves and pants. He has long unkempt white hair that reached his back and long sideburns and a goatee. He wears a black suit with mesh armor underneath, over which he wears a sleeveless kimono-shirt with white fur trimmings, and markings reminiscent of tiger stripes on it, which is held closed by a red sash. Enma also wears a Nohara Forehead protector.

Abilities
Enma is a powerful summon who is also highly experienced and knowledgeable of various techniques and their effects or drawbacks. Physically he is also very strong. Enma is capable of using Transformation: Adamantine Staff, which allows him to turn into a extending and expanding staff that is as hard as adamantine, though despite its hardness, Enma has said that the Kusanagi sword can hurt him. By extending in staff form, Enma can even push Kurama out of Konoha rather easily. He is also able to produce various body parts, such as eyes or arms, from the staff. Additionally, Enma can still move on his own in the staff form, allowing him to return to Mukai. Enma can even clone himself in his staff form, turning him into any number of smaller staffs that he uses for Adamantine Prison Wall.
