Grusha is one of the Gym Leaders of the Paldea Region, serving the Glasaedo Mountain. He specializes in Ice Type Pokémon, and has a Cetoddler as a partner. Originally, he also served as a popular snowborder, but an incident left him unable to continue his duties, and Geeta told him to focus on serving as a Gym Leader instead. He isn't much of a talker, and doesn't find a lot of things "cool".
