Atsushi Domyoji

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
Atsushi Domyoji appeared to the Go-Busters in the heat of battle one day, surprising them that he's their sixth member. 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.

Super Sentai Battle Base
Green Hippopotamus is among the vast pantheon of Rangers which are avaliable in the mobile game Super Sentai Battle Base.

Ranger Key
The Green Hippopotamus Ranger Key (グリーンヒポポタマスレンジャーキー) 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.
