Team Tobirama

Team Tobirama was a team led by the future Second Hokage, Tobirama Senju. Little is known of the team. On its final mission during the First Great Shinobi World War, Team Tobirama teamed up with Danzō Shimura, Kagami Uchiha, and Torifu Akimichi. While being pursued by enemy Kumogakure ninja, Tobirama sacrificed his life to give the others a chance to escape. Before leaving he appointed Hiruzen as Third Hokage. Homura and Koharu would eventually become Hiruzen's advisers.

Trivia

 * Hashirama Senju appears alongside his brother and this team in some flashbacks. However, although Hashirama did train Hiruzen (as a prospective future Hokage), it is unlikely he ever trained Koharu or Homura and only Tobirama was ever stated to be the leader of this team.
