Harmony is the main female protagonist of Pokemon Legends: Z-A. Traveling to Lumiose City with only a bag to her name, she meets up with Urbain, who ends up giving her a tour around the city. Harmony winds up taking an extended stay at Hotel Z, and joins Team M-Z, a group of fellow young adults protecting Lumiose City from harm, and working to get the name of Hotel Z out there.

Throughout his adventure, Harmony takes down rogue Mega Evolved Pokémon, completes the Poké Dex for Mable, participates in the Z-A Royale all the way up to A rank, and protects Lumiose City from being destroyed by Ange.
