Gavan the Movie
Fulfilling their fifteen year old childhood dream to venture into space, Geki Jumonji and Touya Okuma joined SARD and took a mission to Mars with their childhood friend Itsuki Kawai giving them good luck pendants so she can be with them in spirit. However, the two were labelled MIA when their space shuttle mysteriously disappeared. A year later, while remembering her friends, Itsuki found the SARD complex being attacked by a murderous monster and ran for her life with her pursuer catching up to her. By then, a silver-armored figure named Space Sheriff Gavan appeared and battled the monster as he was revealed to be Zan Vard of the Space Mafia Maku. As they fought, Zan Vard held Itsuki hostage until he was hit by an attack of an unknown origin, allowing Gavan to seemingly finish him off with his Gavan Dynamic and rescue Itsuki, who recognized him as Geki as he boarded the Dolgran without further explanations. Summoned to Planet Bird, it was revealed that Geki has spent the last year training at the Galactic Union and now worked as a provisional Space Sheriff in the Gavan-Type G combat suit. Geki was reprimanded by Commander Qom for failing to protect the data that was taken during the fight by Lizard Doubler with the consideration to have Space Sheriffs Sharivan and Shaider, Kai Hyuga and Shu Karasuma, take over. However, Geki convinced Qom to give him another chance and returned to Earth.

Upon his return, Geki met with Itsuki and took her into the Dolgran where she met his partner Shelly of Planet Bird. Refusing to tell her the truth about what happened with him and Touya during the mission one year before, Geki's search took him to Oyama Energy Laboratory where a meteor was being researched. However, Geki found himself being attacked by the scientists and security as Shelly failed to stop Maku's Witch Kill from obtaining the meteor which was needed to resurrect Don Horror. Kill took her leave as Geki and Shelly escaped with their lives, with Itsuki finding Touya's pendant among the wreckage. Geki later revealed to Shelly how he ended up drifting in space after his shuttle exploded and Touya sucked into the vortex's event horizon. By that time, after she broke the code with Shelly pinpointing the location, Itsuki had Geki take her to the location. There, she saw an illusion of Touya as she and Geki followed it into a trap set up by Maku's leader Brighton. Overpowering Geki in his Gavan Type-G, Bright took Itsuki into Makuu Space while having Kill, Van Zard, Lizard Doubler, a group of Crushers deal with the Space Sheriff. Luckily, the original Space Sheriff Gavan arrived to even the odds and got Geki to safety, revealed to have been the one who saved Geki from drifting space and during his fight with Van Zard.

Learning that Commander Qom that he had been relieved of duty, Geki found himself being attacked by Gavan as he ended the youth's indecision as only he could stop the rebirth of Don Horror. The two then found themselves attacked by Lizard Doubler, with Geki saving Shelly before the Doubler sent the two into Makuu Space where he became three-times as powerful. After successfully escaping Makuu Space, the two Gavans donned their combat suits and Gavan stayed behind to destroy Lizard Doubler so Gavan Type-G could proceed to space, destroying an entire fleet of Makuu ships with the Electronic Starbeast Dol before reaching what remained of Makuu Castle. With Sharivan and Shaider holding off Witch Kill and Van Zardo, Gavan Type-G finally reached Itsuki and Brighton, revealed to be Touya.

Revealing that he pledged himself to Don Horror while trapped in another dimension, Touya intended to kill Geki for not saving him while offering Itsuki's body to Don Horror so he could possess her and engulf the entire universe in Makuu Space. With no option left, with Itsuki trying to fight out of the possession, Gavan Type-G mortally wounded Brighton with a Gavan Dynamic to end the ritual. With Makuu Castle beginning to self destruct, Geki managed to save Touya from falling into the abyss as they and Istuki escaped on Dol. Back on Earth, an agonizing Touya finally reconciled with Geki and Itsuki before passing on to his friends' dismay. Shelly later informed that in recognition to his efforts, the Galactic Union Patrol officially established Geki as the new Gavan. Geki then departed from Earth with Shelly, leaving behind a letter to Itsuki, where he stated that he would return to meet her again once he accomplished his duty as a Space Sheriff.
