In DP, can Kazza, Charap, and Gaspar activate the Masuda Method when bred with a non-Japanese Pokemon?

Question

Bulbapedia says that, because of some oversight, they sometimes behave like Japanese Pokemon. Does this include the Masuda Method? Please don't question my curiosity.
Kazza, Charap, and Gaspar are the Abra, Chatot, and Haunter that in-game NPCs trade to you.

Comments

If it gives you a Japanese pokedex entry in black, the game probably still thinks there Japanese pokemon. If thats the case then the Musuda method would have to work, but im not sure.

In these games, they're counted as English Pokemon (example: French Volty from Lt. Surge in Pokemon HG/SS is counted as English in an English game), so you wouldn't be able to use them Masuda wise. Sorry. I hope I helped

Are you sure this is true even for DP?

I'm pretty sure. Both of the games are Gen IV.

Bulbapedia specifically says those traded Pokemon behave differently in DP than in the other 3 Generation 4 games. So if traded Pokemon in HGSS can't activate the Masuda method, then those from DP still might.

Answer 1

Happily, these three Pokemon will work for Masuda breeding in Diamond and Pearl — but only in English copies.

In the English language version of Pokémon Diamond and Pearl, Kazza, Charap, and Gaspar are functionally Japanese in origin; in Pokémon Platinum and all other language versions of Pokémon Diamond and Pearl, these Pokémon have the same language of origin as the game they were obtained in. While language of origin is normally not visible in Pokémon Diamond and Pearl, being a different language of origin does still have functional effects, such as boosting their experience gained by 1.7× (instead of 1.5×) and being applicable for the Masuda method.
