Most likely, Neku won't be in SSB, but I thought of an idea: What if there were exclusive characters for both games? Red from Wonderful 101 could be exclusive to Wii U and Neku for 3DS. My idea for Neku is this.

 

Normal Attack: Scratch move. (The ability you receive in the beginning of the game.)

 

Upper Attack: Thunder or Fire move.

 

Crouch Attack: That charging rush move.

 

Smash Attack: Remember that ability that he performed in the last cutscene where he brought together all the powers of his friends and was able to make the Player symbol appear which caused a super beam? The Final Fusion attack to be more precise. That would be it.

 

So what do you think?

Neku in SSB would be awesome. Always nice to dream of the possibilities. I haven't played TWEWY in so long so I can't really remember the basic moves you earn throughout the game. I do however for a fact remember the last cutscene of the final fusion attack. That was sick. I would totally agree on having that as Neku's Final Smash.
