Obviously it's fake... Doesn't mention Lucario...

good eye. lol ^

Debunked a while ago. Look at the date of the post. 12/6

Serebii on Smashboards is the owner of Serebii.net, and he's debunked everything with Mewtwo in it's roster, pretty much confirming that Mewtwo is out.

Edit: obviously I don't expect you to know who serebii is, but you just have to trust me that he is a VERY credible source on everything pokemon. He posts on smashboards occasionally and debunks everything he knows for sure is fake. 

Thank you, weezy! (or were you being facetious?)

I can't wait to know the whole roster of characters! ^_^ I want this game NAO!

Updated odds of entry list. Keep in mind these factors contributed to this: The fact that there only seem to be room for 4 characters per sticker suggests no more than 4 characters per franchise. This means that the Mario characters for example other than Mario, Luigi, Peach, and Bowser dropped wayyyy down in odds to almost nothing. Also keep in mind that we are still looking for a franchise to fill the last empty spot... hence Isaac's fairly high odds.

Confirmed:

Mario
Link
Kirby
Pikachu
Fox
Samus
Zelda
Bowser
Donkey Kong
Yoshi
Peach
Ice Climbers
Shiek
Pit
Wario
Zero Suit Samus
Ike
Pokémon Trainer
Diddy Kong
Meta Knight
Snake
Lucas
Sonic
King Dedede
Olimar

Unconfirmed (est. odds of entry)

Luigi (99%)
Captain Falcon (99%)
Ganondorf (99%)
Jigglypuff (99%)
Ness (99%)
Mr. Game and Watch (95%)
Marth (85%)
Falco (75%)
Y. Link (15%)
Roy (10%)
Mewtwo (1%)
Dr. Mario (1%)
Lucario (99%)
Krystal (85%)
K. Rool (85%)
Animal Crossing Villager (65%)
Isaac (60%)
Ridley (50%)
Mii (40%)
Geno (30%)
Balloon Fighter (30%)
Baby Mario & Luigi (1%)
Tails (1%)
Robotnik (1%)
Knuckles (1%)
Raiden (1%)
Bowser Jr. (1%)

Other notes: Tails and Knuckles not being on Sonic's sticker lowered them to almost zero odds. The fact that they went down took Raiden down with them. Geno went down as a result of Mario spots being full, but has higher percentages than the others because he could concievably have his own icon. Any questions, feel free to ask.

@ cdude1034: Mind giving a link to the original post of serebii that debunks these myths?

@ allaboutthegames886 no i really meant good eye. lol
