What was the first season of the Pokémon television anime called in English?

The first English season of the Pokémon television anime was called Pokémon: Indigo League.

The season follows Ash Ketchum through the Kanto region as he earns Gym Badges and attempts to qualify for the Pokémon League. His companions include Misty and Brock, while Pikachu serves as his principal partner.

In Japan, this material was broadcast as the beginning of the Pokémon television series rather than under the English title Indigo League. The English branding emphasizes the Indigo Plateau Pokémon League, the competition Ash ultimately reaches after traveling across Kanto.

Episode counts can vary by language and release. The season is commonly listed with 82 Japanese episodes and 80 English episodes, partly because some episodes were edited, withheld, or handled differently in international distribution. “Indigo League” therefore identifies the English season label, not the title of the entire long-running anime.
