Elaine is a young girl from Pallet Town. Her adventure begins one day when Professor Oak calls her and her friend, Trace to his lab for a starter Pokémon. Elaine picks a Pikachu or Eevee, while Trace picks the opposite Pokémon. Oak also gives them each a Pokédex with which to record data on all known Pokémon in the Kanto region to fulfill Oak's dream of creating a full guide on all Pokémon in Kanto.
From here, Elaine and Trace journey across Kanto, collecting Pokémon to build up their teams, and defeating each of the Gym Leaders in turn.
