List of WwwWario's Leaks[]
October 1st[]
On October 1st, 2014, WwwWario posted a blog post with a image of the complete roster. The characters on the roster are hard to make out, but many could recognize Goomba on the roster.

854220 Leak[]
On October 18th, 2014,a user named 854220 leaked 2 images of Shigeru Miyamoto, Rosalina, Daisy and Dark Bowser in Peach's Castle and E. Gadd Cafe. It seemed real, but it was posted on the same day that v.0.7 was released causing many people believing it to be false.
A few hours later the leaker confirmed that it was fake.
STATE: FALSE
mks_leak Leak[]
On October 19th, 2014, a leaker under the name mks_leak leaked 3 images of Boom Boom joining Mushroom Kingdom Showdown. They look very real, however much evidence is pointing toward false because of odd claims
A proof that the Leak is false its the arguments of mks_leak, first he said BoomBoom was unlockable and he just unlocked him, and then he said wwwWario gave him the game with the new characters already unlocked. It was later proved false by the Leaker himself, who was Mightyzinn
STATE: FALSE
Villainger Leak[]
On October 25, 2014, a user named Villainger posted a caps-locked post claiming to be the "roster of MKS v0.8". It bears a striking resemblance to the October 1st leak by WwwWario. However, the fact that K. Rool's image is a 3D model and that it is a bit to the side, that make the leak a bit less believable. However, the leak was proven false by the v.0.8 update.
STATE: FALSE
Cackletta's Soul Leak[]
WalkingtheDogontheStreet leaked Cackletta's Soul being in the game as an unlockable character. The leaker claimer you unlocked Cackletta's Soul by beating Classic Mode as Fawful on Hard. The leaker confirmed the leak to be fake the next day.
STATE: FALSE
OmegaSmash Leak[]
On January 24, 2015; OmegaSmash uploaded 2 pictures, leaking Rosalina and Goomba (with Goombario and Goombella alternate costumes) being newcomers in v0.9, along with Dark Bowser and Midbus alts for Bowser. Peach's Castle was updated to use its appearance in SSF2. Due to obvious flaws the creator didn't notice before posting, he admitted the leak was fake in the comments. The next day, the update was released, officially debunking this leak.
STATE: FALSE
