Who should the first Pokemon 18+ game feature? (Patreon)

Hey all!  We received many recommendation for making the next 18+ game involving Pokemon characters.  So now let's decide who should appear in the first one!  

I will likely be making a little series of Pokemon-themed 18+ games.  They will act as chapters to one story and characters will be able to cross over and return and such.

Who would you like to see featured in the first game?  Personally, I think many of the professors, trainers, gym bosses, and other side characters are ultra-babes, but I know many people requested the main characters.  Let me know if you have any more suggestions in a comment!
