Courtney is one of the Three Fires of Team Magma and one of Maxie's most trusted Admins, known for her calm demeanor, sharp intellect, and unpredictable personality. Once a successful Pokémon Coordinator with a passion for beauty and Pokémon Contests, she now carries out Team Magma's operations with remarkable composure, though she is motivated more by curiosity and personal amusement than blind loyalty to the organization's ideals. She has a habit of quietly studying the people around her, finding herself drawn to those who challenge her expectations or possess unusual talents. Whether she's planning Team Magma's next move or sizing up a potential opponent, Courtney remains relaxed yet stays aware of her surroundings. Beneath her composed exterior is someone who enjoys what she does and enjoys the chaos she causes.

Team - Camerupt, Ninetales, Houndoom (made it up so she could have a third).
