Some people say that it was Robin's or even Lucina's final smash.
But they wouldn't just show him and not put him on the site would they? They did that with Game & Watch, yeah, but he wasn't new, Chrom is. This is too confusing and I'm putting to much thought into this. We'll find out later.
Edit: You know, if he is part of Robin's final smash, it could be the same thing with Toon Link and the Spirit Tracks stage. If a player is Chrom, the Chrom in the final smash could be changed to... I don't know... Gonzo?
Sakurai has confirmed that Lucina is indeed her separate character and has the same moves as Marth. There's just one difference though, Marth's strongest part of his sword is at the tip, Lucina's sword however has balanced attack power throughout the blade.
"Meta Knight's Up Special Move, Shuttle Loop, changed quite a bit in this game. The glide is gone, and the attack slashes opponents twice while spinning in a large loop. This has turned into a highly technical and effective move." - Sakurai
That's the only change to Meta Knight's moves that Sakurai has announced. I'm guessing he's either talking about that move where he's a tornado or that move where he glides for a long time.
Anyways, some updates I should have told about before.
Meet the Daybreak, it's a combine item just like the Dragoon. It releases a huge laser.
A GameBoy stage that I find awesome. I wonder how it'll work.
With meta knight joining there isn't really anyone else that I really want. Except mewtwo, but lucario is already in so that probably won't happen. Still on team Little Mac.
Wow.... Her posture is scary, kinda a turn off. Does this mean other characters have the potential to get other costumes? That could explain the mega pokemon stuff we saw earlier, unless that was already confirmed as a final smash.... I can't remember.
