DonWii, I have no doubt there will be secret characters, never shown, never bio'd on the Dojo...at least ten.

But Snake and Meta Knight are NOT SECRET. They've been shown in clips and pics many times...there's NO reason not to bio them.  They may need to be unlocked...but I'm sure you'll have to unlock Ike and others as well.

Actually, Snake has not appeared in any clip/image [I just went through all 360+ images on IGN] since the last Smash video in November 2006. I could concede that MetaKnight has been shown enough time to no longer be "secret", but I still think Snake could be unlockable (though he is probably the least secret character; after his reveal, most people know he is in Brawl)

I still have 12 weeks to be proven right/wrong.

Anyone here follow the Smash It Up! feature on IGN?
Everytime I see it, I wish all those characters would be in Brawl.

Perfect timing for ScrewAttack to make a Donkey Kong Country video, since we're all talking about Diddy...

On the topic of Diddy... Doesn't he look too Big in the screens? I expected him to be smaller.

Maybe a tad over-sized, but it doesn't seem like overkill...

Oh nintendo, how you tease

Update: Petey Piranha.

In Super Smash Bros. Brawl: The Subspace Emissary, it’s rumored that there will be boss appearances.

This time, I’d like to introduce the first boss you encounter: Petey Piranha!

He... He’s huge!

Too intense!

Locked in the iron cages he holds are the princesses, Peach and Zelda. He looks angry. Wh-what is he doing?

He’s attacking with the iron cages!

You can save either Zelda or Peach, depending on which cage you damage more and subsequently break.

What will happen to the one you don’t save?!

It's like a deadly amusement park ride for Peach and Zelda hehe.

Save Zelda! Save Zelda!

What other bosses could there be? King Boo? Bowser? Waluigi? And looks like bosses are determined by the players you have slected.
