You've seen the images, right?
I have, and I swear I'm not trying to be difficult or sarcastic here, but what do they prove? That he has some images of Palutena, one of which looks like a WIP from a 3D Modeling program.
Seems more likely he ripped the data off the 3ds cart and opened palutenas model data.
Would explain the dlc character leak as well.
Simplest solution, to me, still seems like something like the above. Obviously he would have had to rip the model from Kid Icarus, not Smash.
The leaker obviously
loves attention and stirring the pot. It seems far more likely he's just trying to cause more trouble. An easier way to prove it fake would just be to show us all three source images (Palutena, Mario, and the Background) to prove that he combined them into one image.
I was originally on the fence about if that leak was real, but even if it was somehow faked (so accurately that it's almost
exactly the same as the in-game model), I don't think MFL is the one who faked it.
