So, I was wondering what would happen if you get a Pokemon from a gen II then transferred it to a gen I game then again transferred it to a gen VII game. Will it display (on the gen VII game) as met in the Kanto or the Johto region?
The reason why I am asking this question is because I was wondering if it's possible to get a Mr. Mime to display as met in the Kanto region, without the "silly" nickname, as you can only get Mr. Mime from the gen I games from an in-game trade; while, you can catch Mr. Mime in the wild in the gen II games.
So, if I want to get a Mr. Mime to display as met in the Kanto region, will this method work? I've tested this on PKHex where I generated a Mr Mime without a nickname (with its hidden ability), met in a gen I game and it doesn't seem to detect any problems; however, I am unsure if this is considered "legal".
