Jessie is beautiful, strong willed and extremely determined in her goals. As a member of Team Rocket along with her friends James and Meowth, she has been trying to capture Pikachu and as many rare Pokemon as possible to give to Giovanni. Jessie's mother was also a member of Team Rocket, but when she was young, her mother disappeared and Jessie was put into an orphanage. As she grew older, she decided to join a Pokémon nurses academy for Chansey but did not graduate. Jessie has also been spending her time competing in Pokémon Contests with a dream of winning a Grand Festival. Like many Pokémon Coordinators, Jessie has had her up and downs while competing to win ribbons.
