I don't know if this can be considered script bug or npc, but there is a way to have a Pokemon from another region on your team, basically on events like Summer, I discovered that if you go to the event island (i discovered this on Summer, Vulcan Island) if you leave your team with 5 Pokemons and catch a Pokemon from there, it gets added to your team, and when you let yourself lose and get teleported to the Pokemon Center, you still have the Pokemon on the team (To clarify, i didn't entered Vulcan Island PC, so i was sent to Olivine's PC, and the Pokemon i caught was a Ralts from Kanto) so on this way new players could get mons from another region on their current region, bypassing region lock.
