Pokémon Star Twinkle

Pokémon Star Twinkle, formerly known as Pokémon Stellar, is a Pokémon FireRed ROM hack that serves as a fan made sequel to Pokémon FireRed and Pokémon LeafGreen. It features new protagonists, Aster and Star, and introduces over 300 Fakemon, new regions, and magical themes inspired by Star Twinkle Pretty Cure and Puyo Puyo.

The story takes place in the Kanto region after the events of FireRed and LeafGreen.

The meteors reshape the environment and create new routes, locations, and celestial themed Pokémon.

328 Pokémon from the Stellar Kanto region, along with several official Pokémon that have been improved

New moves

Much harder rematches

An evil organization known as Team Void
