From Bulbapedia, the community-driven Pokémon encyclopedia.
Christie (Japanese: リナ Rina) is a Pokémon Trainer and along with Doyle, was a character of the day in Where Did You Go, Audino?.
Christie joined in helping Officer Jenny in the Audino disappearance mystery after an Audino she was good friends with disappeared. She and Doyle would often argue on who would find the missing Audino first and would compete with one another using their Psychic Pokémon. She also had a hunch that the Audino were being manipulated by some sort of Psychic attack.
Later on, Christie would be partnered with Iris to watch after Mimi's Audino that they had put a tracking device on. Audino soon started acting strange and she and Iris began following it only to meet up with Officer Jenny, Cilan, Doyle, and Ash again. Christie managed to slow one down with Gothita's Telekinesis.
Christie and the others soon found all of the missing Audino and discover that they were being controlled by sound waves created by Team Rocket. She then uses Gothita to battle Jessie's Woobat. After the case was solved, Christie was eager to know if her Gothita helped out more than Doyle's Solosis to which Officer Jenny informed the both of them that Ash's Roggenrola helped out more.
