@PokePlayer Sorry, I think you'd be better off using the official sprites for that. May I redirect you to The Spriter's Resource? I'm sure you'll find a lot of neat stuff there.
See, these two are my own established Mystery Dungeon team. They should have nothing to do with trainers. I just wanted to try editing normal sprites for once, it's just a personal thing that I wanted to show off.
And heck, I didn't even make back sprites for them, so what's the point in using them for regular battle interfaces?
the rom hack is called "pokemon the mystery of arceus" you get to start off with either torchic or piplup. and then, your rival starts off with the opposite. the region is called the akuta region. the pokedex consists of almost all of the pokemon. sound good?
