I thought there where only gen 1 Pokémon in LGPE, even with the breeding.
NOT SURE THO
And a lot of Pokémon suffer from having their pre-evolutions/evolutions introduced in another gen be on the LGPE list. Also, I didn't check everything but I checked 5 and they had it. (Mime Jr. Pichu, Munchlax, Tyrogue, forgot)
