EDIT: There a newer blog confirming and possibly de-confirming stuff. (Link at the bottom of this blog.)
AND HERE THEY ARE!
So... the Mii Fighters are separate from the actual characters... Wait, what? Dr.Mario? Dark Pit? Duck Hunt? Bowser Jr.? Shulk? Maybe the Gematsu leak was somewhat true? I don't even... WHAT IS THIS? WHY DOES SHULK LOOK LIKE LITTLE MAC WITH A WIG? WHY? WHAT? WHY?
EDIT: I FOUND MORE PICS. (but is rumored to be from GameFAQs and not 4chan.)
And, I think that's it. See ya. -Ninty
EDIT 8/25/14: DLC de-confirmed. The leaker wanted to mess with us so he made a fake DLC list.
