Could this Smash Bros. Ultimate Mii costume leak be the real deal?

It wouldn't be Smash Bros. without speculation and rumors, and that's just what we have here. Sometimes the rumors are spot-on, and other times they're nothing more than the fever dreams of super fans. Today, we once again find ourselves staring at yet another supposed leak. Is it real or fake? Hit the jump to see what we're talking about, and see which side of the fence you fall on.

The latest leak comes from 4chan, which has been 100% accurate in the past, and waaaaaaaaay off as well. You're looking at Mii costumes for both Mallow from Super Mario RPG, and the Cacodemon from DOOM. Both characters and franchises that have been rumored for Smash Bros. Ultimate in the past. Did the rumors fuel this fake image, or is it a legitimate leak? I guess we'll just have to speculate until the next Nintendo Direct comes around!
