Smash Hero
With it soley being a Mii Costume, it's no more a "solution" than it was for Dunban, Megaman X, or Protoman.Yeah, Sakurai is a weird one. I understand that reasoning. It's likely this is just a temporary solution for later DLC or Smash 5. It does seem like an attempt at an "Inking solution" however.
I'm still waiting to see how Splatoon plays and stuff before I'm fully on board with Inkling, although I think the character design and concept is really cool.
If this is all it is, then it was a "gift" due to Inklings not having the support for becoming DLC by the end of the Ballot characters.
It comes down to if they get enough support coming out of when the Ballot closes and the characters are chosen. If Splatoon's pre-release hype was enough to warrant these costumes, I am willing to hope that continued popularity as the game expands out over the next few months will have Inklings be a force to be reckoned with.
