"Dash Dynamic!! Go-On Black!"
―Go-On Black's roll call[src]

Gunpei Ishihara (石原 軍平 Ishihara Gunpei) is Go-On Black (ゴーオンブラック Gōon Burakku) of the Go-Ongers. Nicknamed the "Chaser," he is a former police officer with excellent marksmanship and a passion for justice who sees the Go-Ongers de-transform.



His code name as a police officer was "Handsome Detective," and he passed himself off as such until his former partner revealed that Gunpei had never been a detective. He decides he wants to help and quits the police force (because the police had considered the Gaiark out of their jurisdiction) and tells the Go-onger this but is refused. Gunpei decided that the police had lost their sense of justice.

BOMPER explains to him how the three were chosen and eventually decides to help the Go-Ongers by returning the Engine Casts to them the moment they need it most. Bomper decides to make him the fifth Go-Onger, Go-OnBlack, alongside Hanto Jou who becomes the fourth Go-Onger, Go-On Green. Tvicon.png TV STORY-GP 02: Reckless Guys Gunpei initially belittles Sosuke Esumi, Renn Kousaka, and Saki Rouyama for being "just" kids and claims that he is "a man more qualified to be a Go-onger." However, he begins to bond with the team over time. Gunpei does not like sweets, but after he tasted a special cake Saki Rouyama had made, he found it delicious and eagerly accepted a slice.

Encountering the Gekiranger, the Go-Ongers lose the Engine Souls to the Gaiark and Meka. With Ran Uzaki and Ken Hisatsu's help, Gunpei and Saki manage to gain Geki. With Engine-Ken, a new type of Geki fighting fist, Gunpei was able to access his beast spirit (which turned out to be Gunpherd). With this he performs Ganga Ganga Dan, where Gunpherd, apart of his Engine Soul, attacks, as a manifestation of will. Tvicon.png TV STORY-Engine Sentai Go-Onger vs. Gekiranger

After the final battle, Gunpei returns to the police force and finally becomes a detective. Tvicon.png TV STORY-GP Final: Road of Justice

After transforming into Go-on Black, Gunpei says, "Dash Dynamic!! Go-on Black" (ダッシュ豪快!!ゴーオンブラック Dasshu Gōkai!! Gōon Burakku). With the Cowl Laser (カウルレーザー Kauru Rēzā) he can perform the Laser High-beam (レーザーハイビーム Rēzā Haibīmu).

Shinkenger vs. Go-Onger

After a difficult fight against Pollution President Batcheed, Gunpei and Renn were transported to the Samurai World where they encountered Chiaki Tani and Kotoha Hanaori of the Shinkengers. Tvicon.png TV STORY-Samurai Sentai Shinkenger vs. Go-Onger: GinmakuBang!!


Legend War

A few years later, Gunpei fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.

Behind the Scenes

Ranger Key

The Go-On Black Ranger Key.

The Go-On Black Ranger Key (ゴーオンブラックレンジャーキー Gōon Burakku Renjā Kī) is Gunpei Ishihara's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The Go-On Black Ranger Key was mainly used by Ahim de Famille (Gokai Pink), who used it to fight as Go-On Black.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Gunpei received his key and became Go-On Black once more.


  • Though Gunpei is usually portrayed to be the oldest member of Go-Ongers, his actor, Kenji Ebisawa (who was 21 at the time of the series started), is actually younger than Shinwa Kataoka (22) and Hidenori Tokuyama (26), the actors who play Renn and Hiroto respectively and slightly younger than Yasuhisa Furuhara who play Sosuke for a few months.
  • Gunpei's actor Kenji Ebisawa would later go on to play Shiro Mifune in Zyuden Sentai Kyoryuger
