|This article is about a/an villain in Tokumei Sentai Go-Busters and Uchuu Keiji Gavan.|
He belongs to the Space Mafia Makuu, an intergalactic crime syndicate that was defeated by the original Gavan. Modeled after Makuu's first Double Monster, Sai Doubler, Rhino Doubler has a built-in Axial Distorter on his chest that enables him to open a portal to Makuu Space.
Tokumei Sentai Go-Busters
As one of the members of the revived Makuu syndicate, Rhino Doubler escaped to Earth with Geki Jumonji, the current Space Sheriff Gavan, and his partner Shelly pursuing him with the Go-Busters' help. However, Rhino Doubler forms a partnership with Enter. After being killed by the Go-Busters and Gavan in Makuu Space, Rhino Doubler revived as a data-based giant when his lifeless body is infected with the Hikizurikomu (引きずり込む?, "to pull in") Metavirus. This infection also gave the Double Monster's Axial Distorter access to Subspace as he proceeds to open a portal over the city. Luckily, Rhino Doubler is destroyed by Great Go-Buster with Dol's help before the portal fully manifests.
Super Hero Taisen Z
Rhino Doubler was part of an army of resurrected (mostly Super Sentai) monsters led by Space Raider after the revival of Madou Demon King Psycho. They proceeded to attack the gathering of Kamen Riders and Super Sentai, giving them a hard time. Rhino Doubler helped beat Kamen Rider OOO with Ayakashi Chinomanako and Action Commanders Stargull and Sneak Brother. The heroes of recent years were in a pinch until the arrival of a force of Sentai and Rider reinforcements led by Akarenger and Kamen Rider Ichigo. The combined forces of superheroes were able to turn the tide against the Madou army, with Rhino Doubler being beaten back by Kamen Riders Meteor and Faiz. They lined up and used their various finisher attacks to destroy the revived monsters.
