Pokémon (Master Quest): Trinity

She's an contender in the Whirl Cup and like Misty, she's an Water-type Pokémon trainer. She first met Misty after her victory against Ash in the second round to congratulate her before telling her that she will fight against her in the third round. After the battle, Misty congratulates Trinity in her victory. During the finals after dealing with Team Rocket, she eventually lost against the unnamed Trainer and came in second place leading the male Trainer to be awarded with the Mystic Water Pendant. This is from the episode, "The Perfect Match".
