How can I legaly add pokemons not from Kanto region like feraligatr or girafarig? Error screen shows: "Encounter cannot be traded to the active trainer", I'm playing on Switch and I already have national pokedex

How can you legally obtain the pokemon without cheating? The only games available are FireRed and LeafGreen; if RSE/Colosseum/XD do not exist for transferring in, then you can't obtain that species.

Please think about it.
