-For first party characters I would want to see: Ridley, Bowser Jr. / Shadow Mario / Shulk (xenoblade)
For Third party, I'm fine with a few bonus characters ala Sonic or Snake. But I would rather they were third party characters that appear only on nintendo consoles: Neku (TWEWY) / Phoenix Wright / Professor Layton (maybe he would be better as an assist trophy)
- But please no more clones! And some characters do need different move sets

Games can and should tell stories and share ideas through their mechanics. This is the intrinsic element of the medium and this is how experiences should be crafted in video games. No company does this as well as Nintendo and their echoes from the past.
