I think maybe either Chara,  Star Dream or Galaximus should be the final boss. Or maybe they can all be the final bosses, kinda like this:

Star Dream as the normal final boss, and then Chara as the final boss instead if playing on hard mode, and then Galaximus if you have 10 characters in your party like what BoltBlizzard suggested.
