Ash Ketchum turns 10 years old and is able to start on a new journey as a Pokémon trainer. The night before Ash is to meet Professor Oak, he has a dream and breaks his alarm clock. The next day he oversleeps, which causes him to miss his chance at getting one of the three Kanto starter Pokémon: Charmander, Bulbasaur or Squirtle. However, Professor Oak has one last Pokémon at his lab, a Pikachu. Pikachu initially does not get along with Ash, but in the first episode, Ash saves Pikachu from a flock of angry Spearow and they become best friends, developing a special bond. On the way Ash meets Misty, the Cerulean City Gym Leader who loves water Pokémon and wants to join him until he pays her for her bike which was accidentally destroyed by Pikachu; and Brock, the Pewter City Gym Leader who wants to join Ash on his journey so he can become the greatest Pokémon breeder. Ash catches and makes friends with many Pokémon while dealing with opposition from the Team Rocket trio of Jessie, James, and Meowth, and his childhood rival, Gary Oak, Professor Oak’s grandson, who is also a Pokémon trainer and always keeps ahead of him.
Season 1: Indigo League (1997–99)
Ash Ketchum is finally 10 years old, old enough to become a Pokémon Trainer. He wakes up late on the day he is supposed to receive his first Pokémon at Professor Oak’s lab, however, and arrives to discover all the Pokémon are gone. Ash has no choice to take a naughty Pikachu. Pikachu will not listen to Ash or go inside its Poké Ball, so Ash must drag it along with a rope. After many failed attempts at capturing some Pokémon, Ash throws a rock and hits a Spearow.
Finally arriving in Viridian City, Ash is cornered by Officer Jenny who asks why he is carrying Pikachu instead of having it in a Pokéball. After explaining, Jenny takes Ash to the Pokémon Center where Nurse Joy begins treatment on the injured Pikachu. Before Pikachu’s treatment finishes, however, Ash is interrupted by Misty, the girl who Ash took the bike from, who vows to stick with Ash until he pays her back for destroying her bike.
