Who has voiced Pikachu in the Pokémon anime in every language?

Ikue Ōtani has voiced Pikachu in the Pokémon anime in every language.

Ōtani is the Japanese voice actor whose performance became the consistent vocal identity of Pikachu. Unlike most characters in the international versions, Pikachu generally retains the same voice rather than being redubbed by separate actors for each country's adaptation.

In the anime, Pikachu usually communicates by repeating variations of its name instead of speaking ordinary human sentences. That sound was intentionally kept recognizable across languages, helping the character function as a global mascot for the franchise.

The wording can cause confusion because English-language Pokémon productions have credited other performers for special cases. Kate Bristol, for example, voiced a line in Pokémon the Movie: I Choose You! when Pikachu briefly speaks to Ash. Those exceptions do not change Ōtani's status as Pikachu's principal voice performer across the anime's language versions.
