Giselle (Japanese: セイヨ Seiyo) is a school girl who attends a school located somewhere between Cerulean City and Vermilion City.

In the Anime

Ash, Misty, and Brock had met a schoolboy named Joe who attended a Pokémon Trainer's school called Pokémon Tech. Her Japanese voice actor is Yumi Touma and her English voice actor is Roxanne Beck.

Apparently, upperclassmen at the school were bullying younger or less experienced students under the guise of "tutoring". The one responsible for this program was Giselle, a pretty and popular know-it-all.

Giselle confronted and belitted Joe, Ash, and Misty.

Misty, angry at Giselle and her stuck-up attitued, challenged her to a Pokémon battle. Giselle defeated Misty despite a disadvantage and continued to taunt the red-headed Gym Leader.

Giselle then started to lecture her fellow students.

Ash got angry himself and argued that Pokémon Training was more than types and levels - you need to be friends with them, too.

Giselle lauged haughtily and called Ash a beginner. She teased him about having been on a journey for two months and only having two Badges and three Pokémon. She then proceeded to note that Pikachu are an awful choice for first Pokémon, and that they're more fitting as pets for little girls.

Ash and Pikachu were extremely insulted and angered, and challenged Giselle to a battle.

Giselle used a Cubone. Without being able to use Electric-type moves, Ash told Pikachu to fight back in any way it could. Pikachu then begain to attack Cubone with a series of random physical attacks - biting, scratching, etc. Eventually Pikachu covers Cubone's eyes with it's own skull helment and Cubone ends up knocking itself out with it's own Bonemerang attack.

Giselle was shocked by the defeat and admitted that people can't learn through books alone.

Team Rocket then tried to raid the school, but Giselle led the charge against them and got all the students to assist in chasing the criminals away.

Joe and Giselle reconciled, and Joe left the school to collect Badges for the Pokémon League.

Trivia

Giselle was the only girl that Ash showed obvious romantic affection for. In other words, she's the only girl that made Ash act like Brock.
