The world had returned to normal after the fighters defeated both Galeem and Dharkon and the spirits that had been robbed of their physical bodies by Galeem were finally set free from their controllers and peace returned on the new world. However in a parallel universe Galeem had only begun his ultimate goal of creating a new world. All of Equestria's peace was threatened and during times of crisis neither royal sisters could be found. The only ones who could possibly preserve peace was the Smash Fighters themselves. Unfortunately, they were devoured by Galeem's light and the ponies of Equestria were robbed of their physical forms along with many other unlucky victims, except one. Having managed to escape from Galeem's attack, Starlight soon meets Kirby who was also the only survivor. Now joining forces with Kirby, Starlight begins her journey with Kirby to defeat Galeem, the lord of light.
