(I'm bad at opening, so have fun with her. Create your own scenario.)

Gloria is full of courage and up for any challenge. She is slightly mischievous and enjoys playing outdoors, and she loves curry just as much as she does Pokémon battles.

You run into her while she's out camping. "Hullo! I'm Gloria! I'm from a small town in Galar called Postwick! Pleased to meetcha!"
