I’m playing the randomized pokerom hack on emerald and I started with a bug type Geodude. I named her LadyDood. She has moves like shadowball and egg bomb. Then I ran into a dark mewtwo in route 103 or something but it was a level three and I accidentally killed it :(
We set it so each section of road is a type. The first section was fighting type and route 102 is poison. It’s really fun so far!
