Pokémon

, abbreviated from, is a Japanese animated series, which has since been adapted for the North and South American, Australian and European television markets. It is somewhat based on the Pokémon video game series and a part of the Pokémon franchise.

Originally a single series, Pokémon, it has since been made into three series, including Pokémon: Advanced Generation and subsequently Pokémon Diamond and Pearl, which sequentially continue the story of Pokémon, while its spin-off Pokémon Sunday (formerly Weekly Pokémon Broadcasting Station) has broadcast a series of stories revolving around some of the recurring characters, Pokémon Chronicles or, as it is known in Japan, Pokémon Side Story.

Plot
Ash Ketchum (Satoshi in the original Japanese series) has just become a Pokémon trainer in the Kanto Region. He picked Pikachu because, after breaking his alarm clock, Ash was late for his appointment and all the conventional starter Pokémon (Bulbasaur, Charmander and Squirtle) were gone. He has a childhood rival named Gary (Shigeru in the original Japanese series). Ash accidentally destroys a bike belonging to a girl named Misty (Kasumi in the original Japanese series), who starts to follow him to get her bike back, but soon becomes a close friend. Misty endeavors to be a great water Pokémon trainer. Shortly thereafter, Ash battles Brock (Takeshi in the original Japanese series), the leader of the Pewter City gym. Ash initially loses to Brock's Onix, but wins the Boulder Badge in a rematch. Brock then turns over gym leader duties to his estranged father and accompanies Ash and Misty on their journey in order to become the world's greatest Pokémon breeder.

Ash's Kanto journey culminates with him collecting the necessary eight badges to compete in the Indigo League Pokémon Tournament held annually on the Indigo Plateau in Viridian City. Upon his arrival Ash shrugs off repeated suggestions that he should spend his time training and preparing for the tournament. He ultimately loses in the quarter-finals to Richie, a new rival who happens to use many of the same Pokémon as Ash, including a Pikachu named "Sparky".

After the Indigo League, Ash returns briefly to Pallet Town before setting out on a new journey to the Orange Islands where he will compete in the Orange League. Brock eventually parts company with Ash and Misty to pursue Pokémon research with Professor Ivy. At this point a new character, Tracey Sketchit (Kenji in the original Japanese series) joins Ash. Ash collects four badges and competes against the Orange League champion, Drake, a very experienced trainer. The battle comes down to Pikachu versus Drake's Dragonite with Pikachu delivering a devastating Thunder attack to score the knockout blow.
