Not sure if it counts, but Alolan Raichu was confirmed via the leaked design documments to be an alien mutant that was altered by toxins brought from Ultra Space and then refined into spices used for Alola's pancakes and other dishes that the Pikachu line just so happened to like eating.
Then there's the whole Puka episode from way back in the early days of the anime with a blue eyed surfer Pikachu that seemingly had precognition.
