Isn't the name wrong?

Why is the spell called "Thunder"? Shouldn't it be called lightning? Thunder is just sound, no electric. Is this a translation mistake?

The spell is called thunder because when you look in the magic skill tab there's a skill called thunder. I suppose you should also notify GameFreak and ask if they've mistranslated Pikachu's attacks for 15 years.

“	Is this a translation mistake?	„

KR: 썬더 (Sseondeo, translates to Thunder)

JP: サンダー (Sandā, lit. Thunder)

Totally...plus as I recall, KR actually has "Thunder" in plain english under the korean name.

I'm pretty sure the KR one is "lit", too. /pedant

It isn't the normal word for thunder, and its pronunciation sounds like a Korean interpretation of the sound of the English "Thunder".

Mistranslated, seemingly no but we have no idea what their intent was and shouldn't assume that. Could they have better translated a lot of skills names in NA than they did, or at least fixed some names? Yes probably, but that's more of an opinionated discussion that should be on a forum or some other venue rather than on the wiki, unless you have some evidence that it was mistranslated.

(And yea, I agree a lot of skills names would have been better off being renamed in NA rather than being identical to what KR called them, the other way around as well.)
