>>29646567To be perfectly honest, I would like to see the Pokemon Trainer return as an independent fighter, which as strange as it sounds, can actually work.
We could get a whooping 16 skins enabling us to play as 8 protagonists and 8 female protagonists, and each one uses a move you can put in your item bag (i.e. Rocky Helmet, Mach Bike, Bright Powder, etc.), and you have a potentially-hilarious, but still-useful handling of HM Moves. Imagine wondering how the Protagonist Trainer would recover considering that they're normal powerless beings in Pokemon context. Simply have Latios or Latias (or whatever can both fly and phase in and out of existence like nobody's business) to give them that boost they need to recover, or to fly right into an enemy. It sounds dumb and dull on paper, but if they do it right, the Trainer character can do some funny/awesome things. To put the nail in the coffin here, their Final Smash could be using a Z-move, and any one Z-move that would look best in HD could work very well in that environment. Guardian of Alola is something that comes to mind.
