User blog comment:Darth Phazon/Leak Analysis: Bandana Dee & Ridley trailers/@comment-860254-20141026100221

doubt it. Mostly because Bandana Dee would be hard to see on the 3DS' screen in the Smash Run mode, considering Waddle Dees also appear. Cookie Country isn't the best choice for a stage in Smash. The four-headed dragon thing - presumably Landia or whatever - has, as I recall, no relationship with Waddle Dee, nor seems like a memorable character. Also, the end part where it says Magolor pops up, hints to him also being playable or, at the very least, an assist. While possible, I highly doubt it. Mainly, Magolor seems to be the Kirby team's baby, just like Rosalina and the Galaxy team's. Magolor has so far only made appearances in Kirby games that Sakurai had nothing to do with, so I doubt he'd get even an assist spot.

As for Ridley.... he's a boss on Pyrosphere - OFFICIALLY. He's not playable. Do not say "oh well that ones a clone so derp derp derp", mainly because having two Ridley's on the Pyrosphere stage - one a character and one a boss - would be waaaaaaaaaay too confusing. Especially if they have the same moves. Additionally, Meta Ridley is also a boss, so we're not getting him either. Finally, when it describes the Tourian stage, the "I’ve played enough Metroid to recognize that he was on Tourian, with the 16-bit golden boss statue in the background" part stands out to me. It is highly unlikely that a 16-bit item will appear in the Wii U Smash Bros. 75m makes a reappearance, yes, but I'm guessing its due to the lack of old stages big enough to support 8 players. If Tourian would be included, it'd have an updated appearance, just as Wrecking Crew does.

Plus, considering Mewtwo didn't have one, I doubt the DLC characters will have trailers. Maybe it's in development, but I'm doubtful.
