"The swamp Swimmer! Green Hippopotamus!"
―Green Hippopotamus's roll call[src]

Atsushi Domyoji (道明寺 アツシ Dōmyōji Atsushi?) is Green Hippopotamus (グリーンヒポポタマス Gurīn Hipopotamasu?) of the Dobutsu Sentai Go-Busters. He is the 6th Ranger of the team.

Character History

Green Hippo's death

Green Hippopotamus' death

Atsushi Domyoji appeared to the Go-Busters in the heat of battle one day, surprising them that he's their sixth member. (In "episode 15" of the "series") He transformed into Green Hippopotamus. It is implied that he began somehow vying for the affections of Yoko Usami and became Hiromu Sakurada's rival. He was killed in battle more than midway through their year-long struggle against the enemy. (in episode 37)

The Green Hippopotamus Ranger Key.

The Green Hippopotamus Ranger Key (グリーンヒポポタマスレンジャーキー Gurīn Hipopotamasu Renjā Kī?) is a Ranger Key released as part of the Ranger Key Set: LOST EDITION. It is unknown if it will appear in a future crossover. Of course as with all Ranger Keys, should it exist, it would be able to transform one, i.e. Gokai Silver, into Green Hippopotamus.

Behind the scenes



Tatsuhisa Suzuki, in costume as Atsushi Domyoji, and Usada Lettuce as seen in the ending sequence of Tokumei Sentai Go-Busters Returns vs. Dōbutsu Sentai Go-Busters.

Atsushi Domyoji is portrayed by Tatsuhisa Suzuki (鈴木 達央 Suzuki Tatsuhisa?), who voices Usada Lettuce. As Green Hippopotamus, he is portrayed by an unidentified suit actor.


  • He is the first, and currently only, Hippopotamus-themed Ranger.
  • He is the only member of Dobutsu Sentai Go-Busters who does not have a known counterpart, Buster or otherwise, in the main Go-Busters universe.
    • This is similar to how Beet J. Stag doesn't have an alternate reality counterpart.
    • His closest "equivalent" would be Usada Lettuce, for whom his portrayer is the voice actor.
  • His helmet is a repaint of the helmet of Blue Buster/Blue Gorilla, with added ears.
  • He is similar to Burai from Kyoryu Sentai Zyuranger in that they are both green sixth rangers who eventually died. The only difference being Yamato Tribe Knight Burai is brought back for the Great Legend War.
  • While not having a Buster Machine of his own, he indeed was revealed to play a crucial part in piloting Go-Buster Ultimate Animal (the alternate reality of Great Go-Buster), where the Go-Buster suffered a huge hardship in piloting it against a giant alternate Cutterloid until Black Puma gave them the LT-06 and use it to form Go-Buster Perfect Animal.
