Giselle appeared before Ash, Brock and Misty, making Brock and Ash blush at her appearance. Misty challenged her to a battle, as Giselle was arrogant and picked on Joe, her classmate. Though Misty lost, Ash challenged Giselle, using his Pikachu against her Cubone and won, using an unusual strategy. ThoughTeam Rocket attempted to steal the Pokémon, Giselle ordered her classmates to battle, which got Team Rocket scared. Due to this experience, Giselle promised not to pick on Joe.
Giselle appeared in the opening scene of Adventures in the Orange Islands season, but she did not appear in any of the episodes.
Giselle made a few appearances in The Electric Tale of Pikachu. She first appeared in Clefairy Tale, where she was shown traveling through Kanto and catching high-rank Pokémon. She is also seen attending a performance with Joe by Duplica and her Ditto in Pikachu's Excellent Adventure.
Cubone is the only one of Giselle's Pokémon that was actually shown. It is her loyal partner and her most powerful Pokémon. This Cubone seems to have the exact same personality as Giselle, strong and determined. It didn't even waste its time in attacking Ash's Pokémon, it just threw its bone at it. It's defeat came when Ash's Pokémon dodged the bone and it came straight back at Cubone, knocking it out.
Graveler: Giselle used this Graveler to battle Misty's Starmie. Because it was at such a high level, it easily beat Starmie with no trouble at all.
