In {{aniseries|OS}}, a 10-year old [[Ash Ketchum]] starts his {{pkmn|journey}} to become a [[Pokémon Master]], setting off from [[Pallet Town]] with his {{pkmn2|first partner}}, {{AP|Pikachu}}. Traveling through the [[region]] of [[Kanto]], he faces [[Gym Leader]]s to earn [[Badge]]s and encounters challenges that test his skills, often clashing with the villainous [[Team Rocket trio]] and butting heads with his [[rival]], [[Gary Oak]]. Accompanying Ash through his journey are {{an|Misty}}, a tomboyish {{type|Water}} Trainer from [[Cerulean City]], and {{an|Brock}}, an aspiring {{tc|Pokémon Breeder}} from [[Pewter City]].

After competing in the [[Indigo Plateau Conference]], Ash is sent on an errand by {{an|Professor Oak}}, which sees him travel to the [[Orange Islands]] to retrieve the mysterious [[GS Ball]] from [[Professor Ivy]]. While Brock seems to find his true calling as Professor Ivy's {{TP|Professor|assistant}}, his place in {{ashfr|the group}} is temporarily filled up by [[Tracey Sketchit]], a [[Pokémon Watcher]] and an enthusiastic fan of Professor Oak. Ash's delivery mission gets delayed when he learns about the [[Orange League]] and decides to compete in it, giving him a set of new and unique [[Gym]]s to challenge.
