A new Pokken Tournament video has appeared on the Japanese video site NicoNico showing an alternate Mega Evolution for MewTwo. It appears to be a dark alternative to the Mega MewTwo X, and currently there is no official capacity confirming its inclusion.
Viewing the video requires a NicoNico subscription but shows the player stumbling upon MewTwo as a extra battle. It appears in an alternate dimension and transforms into his darker form beginning the battle. Once it is all over, MewTwo reverts back as the world crumbles around him and the video ends. You can see some images from the video below thanks to NeoGAF users Watch Da Birdie and Hero of Legend.
