|This article is about a braneworld in Engine Sentai Go-Onger and Kaizoku Sentai Gokaiger|
Gunman World (ガンマンワールド Ganman Wārudo?) is a braneworld that was threatened by Pollution President Batcheed and his successor, Babatcheed. It is a desert-like landscape with towns similar to those of the American Wild West.
In Samurai Sentai Shinkenger vs. Go-Onger: GinmakuBang!!, Batcheed encountered the Go-Onger in this world and ultimately faced them in combat before tricking them with his death and ultimately sending them through the other Braneworlds.
By the time of Kaizoku Sentai Gokaiger, Batcheed has died and succeeded by his son Babatcheed, who, alongside his minister Barbaric Officer Chirakashizky, invaded this Braneworld in an attempt to bring all Braneworlds under his control. Sousuke and the Gokaiger confront and defeat Chirakashizky in this realm, but Babatcheed ultimately traps them within while he begins an invasion of the Human World. They ultimately escape through Machine World in order to track him and defeat him.
