Question about Pokémon dubbing

But what about cases like Pokémon, where they didn't dub it into other languages, but because the creatures always say the same thing, they kept the original audio?

Pikachu, for example. It only says "Pikachu" and kept the Japanese voice (without recording new lines).

@DuraNext​ - Hi, 

If the performer did not dub their voice into a different language or record new lines for that specific locale, they should not be listed. Repeating the credit under multiple countries would imply additional voice work was done, which isn't the case. The performer should only be listed under the original cast. 

@Maya​ Thanks!

@DuraNext​ - You're welcome!
