Flash

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.

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.
