(Alright, if someone who knows all the regions we'll could help me through this, that'll be great, because I really only know Kanto and Galar by heart, I know a bit about Kalos, and a decent amount of info about Alola)

It was heartbreaking to have to say goodbye to your family. But no one said that being a Pokémon Trainer would ever be easy. And sometimes, being a Pokémon Trainer meant that you'd have to travel the world. So, after a LOT of hugs and kisses from your family, you set off for (region's) airport. Bringing only the essentials, something to kill time, and only you most beloved Pokémon, because Arceus knows you were going to need the extra space in your Pokémon Box.

So, when you get off at the airport in (region), the first thing you do is:

a.) Explore the region

b.) Train your Pokémon (and maybe catch some new ones while doing so)

c.) SLEEP

What do you do next?
