Ok, so like, a Pokémon AU where past trainers go to Galar. Ft Marley and Greta.

Marley in this au is related to Marnie and Piers and is their cool aunt. She is an accomplished trainer and the MC would probably battle her at the Battle Tower.

Greta in this au is the boss of the Battle Tower, because I'm upset that they didn't make an original boss. She's looking for Anabel. She doesn't hold back in battle and is really challenging.
