Early life

 * For more details on Retsu's service as Space Sheriff Gavan, see his page at the Metal Heroes Wiki.

At some point, he saved the future Captain Marvelous (Gokai Red), in his childhood.

Gokaiger encounter
Gavan was contacted by the Space Empire Zangyack to arrest the Kaizoku Sentai Gokaiger on the account of piracy. Gavan arrived on Earth and immediately attacked the Gokaigers' Gokai Galleon with Dolgiran. Gavan subsequently aprehends the Gokaigers with ease and hands them into his superiors. However, Gavan is betrayed by the Zangyack Empire, and bears witness to his replacement, Gavan Bootleg, who tortures Gavan and sends him to the Makku Space Prison.

He is subsequently rescued by the Gokaigers and fights alongside them to eliminate Gavan Bootleg as well as Makku Prison Chief Ashrada.

Trivia

 * Kenji Ohba, who plays Retsu, has had several roles in Super Sentai, including Shirou Akebono (Battle Kenya) in Battle Fever J and Daigorou Oume (DenziBlue) in Denshi Sentai Denziman.
 * He is the only returning actor to reprise more than one role, as Hiroshi Miyachi returns as Soukichi Banba (Big One) and does not play Akira Shinmei (AoRanger) at any point, Teruaki Aguwa returns as Hyuuga (Black Knight II), but not as Sasuke (NinjaRed), and Jun'ichi Haruta returns as Kanpei Kuroda (GoggleBlack), but not as Ryuu Hoshikawa (DynaBlack).
 * Technically, both Akira and Sasuke do have lines in Gokaiger Goseiger Super Sentai 199 Hero Great Battle, but their respective actors only say them in full costume. Neither appear outside of their transformation.
