Pokémon: Indigo League contains 80 English-language episodes.
Indigo League is the first internationally named season of the Pokémon animated series. Its English episode count is 80, while the Japanese version contains 82 episodes. The difference exists because two Japanese episodes were not included in the standard English season count.
The season follows Ash Ketchum through the Kanto region as he travels with Pikachu, Misty, and Brock. It adapts the setting and creatures associated with the first Pokémon games, but it is not a direct retelling of the games' plot. The anime adds original stories, recurring characters, and its own version of the Pokémon League journey.
The season originally aired in Japan from April 1, 1997, to January 21, 1999. Its English-language run began in the United States in 1998. The distinction between 80 and 82 is important because references may be counting the English or Japanese version.
