Zaku Abumi (ザク・アブミ, Zaku Abumi) was a shinobi from Otogakure and a member of Team Dosu, which took part in the Chūnin Exams under covert orders from Orochimaru.

Zaku was one of Kin Tsuchi’s teammates during the Chunin-exams. Zaku has shown little care for his team-mates or other people. He was only loyal to Orochimaru.

Zaku was used by Orochimaru as one of the Edo-Tensei sacrifices for the summoning of the First and Second Hokage, Hashirama Senju and Tobirama Senju.

He was one of the enemies which Naruto Uzumaki faced in Kin´s mind.
