Bankotsu

Bankotsu was a temporary member of Team InuYasha, during the First Warriors War. He formed is own team from the start of Second Warriors War. His team acted like a morale support since his team represents "strength".

Operation: Blow Away
Until the last minute of the First Warriors War, Bankotsu bounded to Team InuYasha's side and fought against Sasuke and his invading allies. With the deaths of the members of Team InuYasha, Bankotsu reported to Sesshōmaru about their deaths, leading him to strike and blamed InuYasha for his incompetence.

Bankotsu stated the Akatsuki will invade the lands.

Akatsuki's Invasion
Pein and the Akatsuki. Victory was assured though Pein's Shinra Tensei destroyed the lands.

Start Wars
Bankotsu stood beside his childhood friend, Jin Kariya who fought against Sasuke's forces. At this time, Bankotsu saw how Zaraki Kenpachi, a warrior having the same characteristics as his in terms of being keen on fighting. Throughout the course of this war, Bankotsu recruited Kagura, Ino Yamanaka, Orochimaru, Kisame Hoshigaki, Tenten and Dark San. Team Bankotsu was formed.

Reverse Time
Enemies reversed time to have Sasuke returned. Bankotsu and his allies fought against Sasuke's forces. Bankotsu also helped Jin to destroy Kisame's evil clone. Few days later, Sasuke was powerful enough and unleashed a devastating attack, killing Bankotsu, InuYasha, Itachi Uchiha, Jin and other warriors.

Two months later, Sesshōmaru revived him and the others.

Tobi's schemes
Bankotsu pondered about Kagura's death as well as Orochimaru betraying him and his allies. He learnt that Orochimaru was nowhere to be seen. He participated in the Fourth Warriors War which was initiated by Tobi. He witnessed Sasuke battling Kisame until the point of death. Aizen Sōsuke imprisoned and questioned Kisame who committed suicide. Angered by this, Bankotsu recklessly rushed against Aizen. He was too powerless to intervene due to his valuable ally's death. The next day, he wondered about Aizen's status. Jin brought up the good news that Sesshōmaru destroyed him. Yuka Minase, a member of Team InuYasha couldn't fight, but unleashed her powers to negate enemies' powers which was enough to give Sesshōmaru the chance to eliminate the man responsible for threatening Kisame.

Bankotsu witnessed the conflicts in the Land of Fairies where Kirigaya Kazuto and Yui headed to the World Tree where Yūki Asuna was held hostage. The World Tree was heavily guarded by a fraction of Sasuke's warriors led by Naruto and Hime.

Tenten's gone missing
Later that day, Bankotsu teamed up with Sango and fought against the undead members of Seven Swordsmen of the Mist and X-cution. Bankotsu and Jin attended Kisame's grave and honoured his death. Seeing the teams are turning tables, Bankotsu and Jin fought against Jinpachi Munashi and Kushimaru Kuriarare.

Ultimate Showdown between InuYasha and Tobi
Upon hearing the news that the undead Madara Uchiha was brought on the battlefield, Bankotsu witnessed Tobi and a group of seven Jinchūriki against InuYasha. Throughout the midfight between InuYasha and Tobi, Bankotsu saw the undead Madara fighting against Byakuya and Kenpachi.
