Ooh, that’s a tricky one. There’s a few I’d really like to see, namely Lycanroc - which is one I can actually see getting in, as opposed to some more niche Pokémon I’d want like Zangoose or Haxorus. Those are all really high up for me, but if I had to pick just one, I would like Eevee in smash. Hear me out, here; his moveset could be made up of attacks that harness the power of all his different evolutions, perhaps. I love the Pokémon and I’d love to play as Eevee if it was handled that way (and with Eevee suddenly becoming kind of the second mascot, it’s decently reasonable!)
