This would seem to confirm Ness, Jigglypuff and Lucario, but I'm not sure it deconfirms Mewtwo; at least not as emphatically.

Crazy find.

Sure is. Has anyone confirmed whether or not the video was re-edited?

That is what I'm hearing now.

The sticker in question was the legendary Pokemon Groudon.  If it was going to react with anyone, Mewtwo should have been top of the list, and should have easily replaced Pikachu or Jigglypuff (assuming limited character spots).  Odds of Mewtwo in the game down to 1% by my estimation (see list above).

What KIND of pokemon is it? I got one in D/P like everyone else, but I didn't like it very much and I already had an established team at that point, so I just stuck it in my PC's box.

I found both the Ness and the Lucario/Jigglypuff frames. Around 4:20. But something seems a little funky about it. If you just let it play, it goes right by without the faces being noticable.

He's fighting/steel dual type.  He can either use special or physical attacks, depending on how you decide to customize him.  He should be a very balanced character in Brawl.  His moveset is perfect for the game. 

Does anyone think Ness, Lucario or Jigglypuff may be the update tonight? I really doubt it but you never know.

I want MARTH and ROY, Especially ROY!

Tails or Knuckles would be nice, especially if it was a combo possible for sonic/tails like in the games (sonic3, ect.)

I do NOT want Shadow! Maybe as an alt. color for sonic, but otherwise, he will be either just like sonic, or fox, or he'd get his motorcycle like Wario...

I suck with Marth and Roy. Marth might be in but I doubt Roy will be back.

I just watched the video, and Ness's face is still in it, and it's even clearer then the screenshots here.

The stupid player is buggy as hell though. I wish they'd just use a Youtube embed.

EDIT: Lucario and Jigglypuff are still there too, but they are just a flicker. You have to pause it to see it. It still

looks better there than though...

EDIT [AGAIN]: Actually, It's like Erik Aston here already said. It's like pausing "decodes" it and shows the bottom of the sticker's chart, which is normally white. the window also changes shape & size. This is true on the PKMN set, Ness, and Sonic.
