10 Pokémon characters are way too much. I would say 6 max (Pikachu, Jigglypuff, Charizard, Mewtwo, Lucario, Greninja).

If a seventh Pokémon character were to be added (which won't be happening) then it probably would be a grass starter from either Gen II, III or V. And then I would choose a Mystery Dungeon styled Grovyle.
