After her friend, Blue stopped playing with her, Leaf, being 10-years-old, started to be interested in Pokémon. One day, Professor Oak calls both and gives them the choice of selecting one of three starter Pokémon. Moments later, the professor gives both a PokéDex, and gives them the mission to complete it with all species of Pokémon, which had been Oak's dream from long ago.
While Leaf advances through Kanto, collecting Pokémon and defeating Gym Leaders to compete in the Pokémon League against the Elite Four, her rival Blue seems to be always one step ahead. The main conflict Leaf must face is Team Rocket, a group of criminals who want to steal Pokémon and related objects to cause trouble. Leaf later finds Giovanni, the leader of Team Rocket she'd faced twice, is the last gym leader she must face before continuing her way. After being defeated once again, Giovanni decides to leave Team Rocket and the group apparently splits forever. Leaf becomes the champion of the Pokémon League after beating Blue, and nothing is heard about her until some time after.
Leaf later ventures through the Sevii Islands, where she aids Celio, a man attempting to make communications reach the Hoenn region, by recovering pieces of Ruby and Sapphire, needed for the machine Celio had been preparing to work. While she is there, she finds remaining Team Rocket grunts, who are presumably the ones who rejoin it into Neo Team Rocket in Pokémon Gold and Silver.
Post-events of Pokémon FireRed and LeafGreen, Leaf was shown to have taken a separate path to Red. Red continues on as a wandering trainer, eventually heading to Mt. Silver, whereas Leaf departs from the main storyline entirely and presumably, all of Kanto. With her absence, Lance of the Elite Four assumes the role as Champion of the Pokémon League during the events of Pokémon Gold and Silver.
- In Super Smash Bros. Brawl for the Wii, the playable character Jigglypuff will wear Leaf's hat in one of its alternate costumes.
- Leaf appeared in an early trailer for Pokémon Battle Revolution where she defeated Red with her Groudon and Pikachu.
