Hōki (Watari)

Oki the migrating ninja was a ninja that masqueraded as Mōsō in the Land of Birds. In disguise, he served as Chief Advisor to the Feudel Lord Owashi. He leads The Wandering Ninja. Despite being its leader, Oki's skills do not seem on par with those of his group. When Mōsō was chief adviser, he secretly poisoned Owashi resulting in his death. Sagi (who was really Toki) took on the guise of Noroimusha in hopes to avenging her father. When the threat of this occured, Mōsō sent Chishima to the Hidden Leaf Village for help and Tsunade dispatches Naruto Uzumaki and Team Guy (minus Rock Lee) to the Land of Birds. When Chishima overheard Mōsō's true plot, he got away and barely escaped Nagare, Hokushin, and the other Wandering Ninja whom Mōsō dispatched

When it came to the final conflict, Mōsō trapped her in a imitation jutsu (and discovering Toki's duo identity at the time) as Naruto, Neji Hyuga, Tenten, and Kakashi Hatake arrive. As Mōsō eventually makes off with Toki, he leaves the Leaf Ninja problem to Hokushin and the other Wandering Ninjas. Despite this, Naruto tricked him into revealing his true self when he used clones to disguise his position. During the attack, Chishima was wounded by Oki. Naruto defeated him with Naruto Uzumaki Barrage. Oki was handed over to Toki, and Naruto requested that he be forced to repent of what he had done.

Abilities
Many of his techniques are weaker copies of the actual versions (his "summoning technique" activating a projector is just one example, or using strings to make it appear that his enemies have been caught in a which is the specialty of the Nara clan). His strategy seems to involve mainly deception, which allows him to overcome stronger foes. Oki even copied Sasuke Uchiha's Fire Style Jutsu which he used to knock off the Noroimusha mask.

He is also talented at Genjutsu when a flashback showed him winning the trust from Feudel Lord Owashi by swallowing a sword.
