I think I only have one more character to unlock, and I honestly do not know who it is or how to unlock it. I have an idea... based on some unsubtle hints heard in one of the gaming podcasts I follow. I did a really great job of avoiding Brawl spoilers.
I personally expected just about everybody from Melee to show up in Brawl, so I don't really consider guys like Falco to be meaningful spoiler material. Out of all the folks I've unlocked (and you get quite a few for completing Subspace Emissary), two were complete surprises, and that was cool.
As I post more of these photo entries, I'll gradually reveal all the spoiler characters, so watch out.
It seems odd to us Americans, but Sonic is only five years older than Charizard. And he can't breathe fire. Weird!
Ash - come on, let's just call him Ash - can't bear to see his little buddy about to asplode on a bob-omb.
That delicate-looking Metal Gear is from MGS4. Pretty cool that Kojima allowed Nintendo to use elements from a game that isn't even out yet.
Ready? O! K! Samus Sister Cheerleaders are go!
The only problem I have with the camera itself is that you can't zoom all the way in. I would like to get microscopic on these guys. It's weirdly situational... for example, on the Halberd stage, you're even more restricted.
Tingle would have been a great playable character. I hope they're working on that for Super Smash Bros Donnybrook, due in 2015 for the Nintendo Woo.
Sausages! I'm a big Mr. Game & Watch fan, although I rarely win with him because I get distracted just watching him animate.
