Flash, also known as Red Star or Flash Star, is the red central planet of the Flash System and the main homeworld of the Flash race who lives on this world. It is surrounded by the Yellow Star and Pink Star.
This is also the planet where Jin, the eldest of the five abducted children saved by the Flash, grew up and where he studied, trained and built various weaponry for when the team returned to Earth. When the Flashmen left for Earth, they stole Round Base departing from this world after storing all weaponry and vehicles needed for their mission.
Flash is also the homeworld of Hero Titan, who used the technology and the great power of his home planet in the past to create the Flash Titan mecha. The energy from within the planet is stated to be unlimited and was powerful enough to power up and reforge the team's Prisms after they had been destroyed.
