Falco and Mii Swordsman are the only characters without a player listed. I know Falco seems relatively unexplored in this game, but damn...
I would be the best Falco there ever was... If I had a Wii U.
That and there aren't any notable, like big tournament or big results Falcos. Keitaro is on and off with Falco, GimR is, well, GimR, I don't know if Cyro has placed anywhere, and pawclaw did show up at Apex and I believe he placed in local tournaments while Kato showed up or has some results on showdowngg tournaments, and I don't know about FOW. So, yeah... I mean, even Mii Swordfighter has guys like Emblem Lord exploring him, but because of the previous rulesets against customs and limiting Mii Fighters, they haven't had any major exposure, so they get a pass, but then you have a character that can be used anywhere, but doesn't have any notable results. Even Zelda, Samus, DK, Mr. Game & Watch, ROB, Wii Fit Trainer, Dr. Mario, Duck Hunt, and other sleeper/underused characters have results or something notable like Nairo using Zelda. Anyway, I digress and I'm complaining as usual.
So, nobody's declared themselves as a major Falco main and took names and kicked *** yet.
