I dont disagree with most if not all with qhat you said. Im looking at it as what can Sakurai do in terms of WTF impossible character to add to the game. In Brawl it was a third party character that has history with Nintendo. In SSB4 it was Cloud who ever was like WTF he never be in the game. Hell you can say Bayonetta as well
I feel like this game out of rule character would be Goku. Im not expected it, but i dont think its impossible is all im saying. Its definelty a less than 0.1% but above 0.0% :p
I wouldn't say Bayonetta, because her games actually came out prior and Nintendo had a really close relationship with Platinum games. Cloud on the other hand... that's a fair point.
I... will... concede... that... there... is... a... some... less... than... inkling...of... a... chance... thathemightgetin.
