Enma (猿猴王・猿魔, Enkōō: Enma; Literally meaning "Monkey King: Enma") is the personal summon of the Third Hokage and king of the monkeys. He possesses great physical strength and fighting ability, as seen when he fights off both the First and Second Hokages. Enma is capable of using Transformation: Adamantine Staff (変化・金剛如意, Henge: Kongōnyoi; English TV "Transformation: Adamantine Nyoi"), which allows him to turn into a large, extendable staff (a Ru Yi Bang or nyoi-bō) that is as hard as adamantine yet as sharp as a sword. He can also produce various body parts, such as eyes or arms, from the staff. Additionally, Enma can still move in the staff form, allowing him to return to the Third Hokage. Enma can even clone himself in his staff form, turning him into any number of smaller staffs that Enma uses for Adamantine Prison Wall (金剛牢壁, Kongō Rōheki).

Enma is fiercely loyal to Sarutobi, though he doesn't always approve of his actions. Sarutobi's actions in regards to Orochimaru is something Enma keeps reminding Sarutobi of. Enma would have preferred to kill him the first time. Enma is seen in a flashback of Orochimaru's defection, urging Sarutobi to kill Orochimaru, thus his current attitude. He's also quick to anger, as seen when he simply tries to break Orochimaru's neck after Orochimaru injures Sarutobi.

Enma's first appearance was his summoning during the battle with Orochimaru to even the odds against the resurrected First and Second Hokages, now Orochimaru's minions due to his Summoning: Impure World Resurrection. With Enma on hand, Sarutobi was able to hold his own until he realized that his resurrected opponents would never die. Therefore, Sarutobi decided to seal both their souls and Orochimaru's, ending their threats forever. As Sarutobi attempted to seal Orochimaru's soul, Orochimaru tried to plunge his Kusanagi sword through Sarutobi's chest. At the same time, he restricted Enma with some of his snakes. As a result, Enma was only able to catch the sword after it had impaled Sarutobi. He held it back until Sarutobi sealed Orochimaru's arms, at which point he pulls out the sword before vanishing, noting that Sarutobi died a "true shinobi warrior" and a "great Third Hokage."
