Katharine is a character appearing in the Best Wishes! series.
Pokémon the Series: Black and White
She is a kind-hearted trainer, but is constantly manipulated by her Gothita. Seeing her Gothita having crush on Ash's Scraggy, she challenged Ash to a battle with the condition that if she won, she would take Scraggy for Gothita. However Ash managed to defeat her Mandibuzz and thus saved his Scraggy. After the battle, Katharine took shelter with the heroes and took a nap, but was worried about her Gothita, who ran away with Scraggy and Axew. After Gothita and the others were found and rescued from a Garbodor, Katharine had a fight with Ash, using Gothita against Snivy. Snivy managed to defeat Gothita, who ran away, while Katharine followed her.
She appears in a Pokémon Center at Unova League, with her Minccino.
