You say a Pokémon and I'll guess the region or came from

This is a test for me

You see, I was playing Pokémon Go and caught a whole lot off Binacle

Already having Barbarnacle, I wanted to Transfer them all away

So I went to my Box, which is in order by number, and started scrolling to Unova, where I thought it came from

I was so confused, triple checking Unova and everything to Johto

I was like "I know for a fact it's not from Kalos!"

I checked

It's from Kalos

So now I'm curious on how much I actually know

So I want you all to please put a Pokémon in the comments and I, without using any source of Dex, will determine the region it comes from
