Green (game)/Games/Protagonist

Leaf's adventure begins after Professor Oak calls her to his lab and gives her a choice of Pokémon. challenges Leaf to a Pokémon battle as soon as they get their Pokémon. Later, Professor Oak calls the two back, gives each of them a Pokédex, and sends them on a journey to fulfill their dream of capturing every kind of Pokémon.

Leaf travels all over Kanto, filling in the Pokédex and defeating the Gym Leaders. Her rival Blue constantly stays one step ahead, and shows up quite a few times to impede her progress. When Leaf eventually reaches the Elite Four, she finds that Blue has beaten her to a milestone yet again and has become the Indigo League. Leaf defeats Blue in the final battle, and becomes the Champion herself. Her adventure continues even after that, with Leaf discovering new places, such as the Sevii Islands.

Leaf's main conflict in the games, aside from Blue, is Team Rocket, an infamous group of Pokémon thieves. Leaf clashes with Team Rocket many times in her quest. She defeats a group of grunts at Mt. Moon who are attempting to steal rare Pokémon Fossils, and defeats another group ahead at a bridge in Cerulean City. Leaf protects the Pokémon Tower and Mr. Fuji in Lavender Town and destroys their hold on the Game Corner. After she foils their plot to take over Silph Co., Leaf encounters Giovanni, the leader of Team Rocket, as the final Gym Leader in Viridian City. Upon defeating him, Leaf stops the group's world domination plots once and for all, though a few remaining grunts, many who appeared and were defeated by Leaf on Five Island in Generation III, would band together in Johto to try to revive the group.
