I dream and hope that Kumatora would get some recognition in the upcoming Super Smash Bros for Wii U and 3DS. Especially the 3DS version which has had a special focus on handheld games such as Mother 3.
It might seem like a lot to ask to get a third character from the Mother series, but considering the similarities between Ness and Lucas, I believe the Mother franchise is well known enough, at least in Japan, to warrant one more original character.
As a character she has a very unique look with her large blue sweater and short pink hair. A large contrast to the other women currently announced for Super Smash Bros. Her use of psychic powers would give her an interesting move set unlike Ness or Lucas. Perhaps a special move assault type character more along the lines of Link or Pelutena.
I am just an Earthbound fanboy, so that is my primary motivation for wanting Kumatora to appear in Smash Bros for Wii U and 3DS.
At the very least, I would love to see a trophy of her, and see how Sakurai decides to update her into a 3D model in full HD.
