Luvdisc was one of the Gym Leaders' Pokémon that was to fight against Team Aqua and Magma.
Wallace participated in the Fallarbor Town's Contest with his Luvdisc, Elizabeth. Since a man accidentally lit a woman's shirt on fire with his cigarette, Elizabeth doused the flames with Rain Dance. The man and the woman started arguing, so Elizabeth used a Sweet Kiss to calm them down. Ruby was envious of Wallace and challenged him to a "out-of-Contest" battle. Wallace and Elizabeth won that battle, even if Ruby used four of his Pokémon. However, Elizabeth was surprised when Ruby asked Wallace to be his mentor. Hearing Ruby was the son of a Gym Leader, Wallace had Elizabeth free Anorith and Lileep, to see how would Ruby deal with the situation.
Arriving to Fortree City, Ruby wanted to train with Wallace, who sent Seaking, Charles and Elizabeth. However, Wallace canceled the training, since he had to check something that looked like trouble to him. Wallace went after Ruby to Slateport City, but found the place flooded. Thus, he had Elizabeth, Charles and Whiscash, Phillip, rescue the citizens.
Wallace and Elizabeth joined Roxanne and Brawly in the battle against Groudon. However, the three faced the Team Magma admins. Wallace faced Tabitha, who used Torkoal. To stop his Torkoal, Phillip tickled Torkoal, while Elizabeth used Water Sport to reduce the power of its fire-type attacks. Elizabeth flew with Wallace to Sootopolis City, where they assisted Ruby, Sapphire and Winona in the battle.
Ruby recalled how Wallace and Elizabeth calmed down the two people during the Fallarbor Town's Contest, when his Feefee got beaten up by Maxie and Archie. Ruby claimed Wallace and Elibazeth shared a bond they carried in their hearts that allowed them to calm down those two people and wished he had the same beauty with Feefee, too.
