Nothing to see here. Just an elaborate hoax.
[Update] It looks like "leak" of Rayman's inclusion in future Smash Bros. DLC was nothing more than a well-crafted prank.
The guy behind the hoax posted a video on how he pulled it off.
Check it out below.
[Original Story] Pictures and video footage uploaded today on NeoGAF indicate that Ubisoft character Rayman will be a playable fighter in upcoming DLC for both the Wii U and 3DS versions of Super Smash Bros.
The leaked media shows Rayman posing like he's ready to join the fray, and an uploaded video shows someone selecting the limbless hero on the game's character select screen.
It's worth noting that whoever is releasing this information also has Mewtwo, an already confirmed downloable character, on their select screen as well.
Nintendo has yet to confirm the inclusion of Rayman, so stay tuned to NWR, as we'll be sure to provide more information as soon as it becomes available.
