Robin’s Nosferatu gives damage to others while recovering yours, the first ability in a Smash Bros. game to do so.
Robin doesn’t use Dark magic like Nosferatu in Fire Emblem: Awakening, but it was added to his moveset in Smash in order to make him unique.

I noticed something interesting in the newest screen shot, but this is so far simply a theory. I noticed how Little mac's face seemed beaten up during the K.O. and i immediately remembered how in Brawl, during development they cut the idea of "Battle damage" being seen on characters. This may be a little bit of a easily undone theory, as mario is currently K.o'd as well but seems fine. But its known characters like L.M can one hit k.o characters. Thoughts?

While maybe that may just be part of Little Mac’s screen KO animation, that might also be the case, with at least some characters having visible battle damage.

Or, since this is something that actually happens in the Punch-Out!! games, that could be something exclusive to Little Mac.

Screen KO’s are back, with hilarious expressions when the fighters hit the screen!
Star KO’s will appear too, but when a timed match is near its ending, Star KO’s won’t happen.

Cats (or should I say Nintencats?) also appear on the Living Room!
This cat in the screenshot looks particularly similar to Sakurai’s cat…

Sakurai answers why Robin and Lucina are in Smash Bros.

Sakurai recently talked about the latest inclusions in the Smash Bros. roster on the Japanese magazine Famitsu.

Sakurai acknowledged that many people are wondering why Robin and Lucina joined the fray, but Chrom didn’t. Sakurai said that Chrom was indeed considered at some point, but after fully playing through Fire Emblem: Awakening, he realized that Chrom wouldn’t bring anything to Smash that Marth or Ike haven’t.

Conversely, when he considered Robin, everything fell into place easily. His moveset, the fact that he would be able to represent many characteristics from Fire Emblem gameplay… So, Robin was immediately chosen.

Lucina was going to be in originally as an alternate skin for Marth, similar to the male variant of Wii Fit Trainer or the female variant of Robin. However, the characteristics of her attacks ended up being different from Marth’s, which made her turn into a separate fighter. You could say she was lucky in joining the fray.
