User blog:David eric/Leaked Mewtwo Gameplay!?

Theres a ideo showing Mewtwo gameplay posted in a japanese channel. It shows Mewtwo fighting Captain Falcon on Pyrosphere.

https://www.youtube.com/watch?v=SMroSfFDxAQ I thin it's fake as it shows not much and I feel I saw Mewtwo's model in another Brawl Mod. But what you guys think?
