Yamato (ヤマト), also known as "Tenzō" (テンゾウ, Tenzō), are both code names for this Anbu-turned-jōnin of Konohagakure. As his Wood Release would allow him to be able to keep the Nine-Tails sealed within Naruto Uzumaki in check, he was re-assigned from Anbu to the regular forces, joining Team Kakashi as a temporary replacement for their jōnin-sensei, Kakashi Hatake. While Kakashi eventually returns to the team, Yamato stays on to provide assistance as needed.

He was made using the body from Anime Heroes Kakashi with the head from a Yamato keychain

I had to drill a hole into the bottom of the head to fit the neck then glued it on the neck joint of Kakashi

Nothing else was changed
