Roxie proved herself to be a very capable Gym Leader, defeating five of Ash's six Pokémon despite being at a disadvantage in terms of her [[party]]. She would occasionally perform a riff on her bass during the battle, and the crowd would chant her name. When she was defeated she happily congratulated Ash as the crowd cheered for his victory, and she presented him with his eighth and final Unova Badge, the Toxic Badge.
Roxie appeared in a flashback in ''[[BW103|Curtain Up, Unova League!]]''. She also makes a cameo appearance in the credits of ''[[M16|Genesect and the Legend Awakened]]''.
