|Trainer class||Clerk/Team Protectorate Ensign|
|Member of||Team Protectorate|
A young woman Leinad befriended during his Pokemon Gym Challenge, she was randomly attacked by Team Devastator 4 years after meeting Leinad. Fortunetely, Leinad and the recently-recruited N were nearby and managed to drive Team Devastator off. Leinad recruited her to Team Protectorate and she managed to reach a leadership position in the organization.
Trisha is a very social person, so, when she's alone, she gets real sad. She described Leinad as the 'little brother she wished she had'.
- Like Maya, Trisha is taken from Pokemon White/Black as one of the people the player can meet at the Nimbasa Ferris Wheel.
