Katharine is a Pokémon Trainer that has a very selfish Gothita. Katharine and Katharine's Gothita form a combo and are now visiting gyms in the Unova region. At the time she met Ash Ketchum and his friends, Katharine had two badges: the Basic Badge and the Insect Badge. Katharine tends to follow the will of her Gothita and spoils it a bit by abiding by whatever it wants to do despite her initial thoughts and reactions to a situation.
Despite submitting to Katharine's Gothita selfish attitude, Katharine seems to be a nice trainer and was planing to head to Raimon City next as she was a big fan of Elesa. Katharine was last seen chasing after her Gothita as it ran off into the distance after it lost the battle against Ash's Snivy.
