Pokémon HarmonY is a romhack of Pokémon Y that changes all obtainable shinies and swaps Team Flare for Team Plasma.

Other primary features include BREAK evolution which lets final stage Pokémon permanently evolve into a powerful golden form, the new Harmonic type and Kalosian forms which change not only the color palette of a Pokémon but also their typing, move set, stats etc.

Encounters and trainer teams are also changed, along with various smaller quality-of-life features.
