Most likely to be included

[baheffron]

Which characters do you think will most likely be in Brawl? This does not include any confirmed characters or characters from melee. (Be practical here, guys.)

In no particular order:

Diddy Kong
Toad
Crystal/Wolf (Either one would be a good choice, perhaps both)
One other F-Zero char. could be any that they want
One other Fire Emblem char., maybe even two

I would be willing to bet money that these characters will be in the next smash. ;)

Wolf, Deoxys, Lyn, Lucario, Krystal, Diddy Kong, Geno, and Sonic would be the more likely ones.

[Shark X]

Diddy Kong for sure. Pratically no doubt that he'll make it in, since now that Meta-Knight and Wario are comfirmed, Diddy is all thats left thats the top most deserveing.

Dedede. I don't think he fits yet (next one for sure, but leave all the glory for Meta-Knight this time around), but considering Sakurai himself says he wants to include Dedede, I'd bet he's included for sure.

Wolf and Krystal. Both of these are all thats left thats deserveing.

As much as I liked to say Toad, I highly doubt he'll be included, ever for that matter.

Sonic. Wasn't in confirmed in some official Nintendo guys blog that he was going to be included anyway? Even before it was confirmed, Sonic is the largest choice for 3rd party. Even larger than Snake.

Deoxys. As much as I hate any Pokemon beyond Red/Blue, Deoxys got popular real fast, just like Mewtwo. In fact, Deoxys is like the current gen Mewtwo.

Diddy Kong would be the one character that you could almost count on

[Shark X]

Diddy Kong would be the one character that you could almost count on

Exactly. He, Meta, and Wario. And two of those three have already been confirmed.

[tirkaro]

deoxys is more likely being that he is a popular pokemon and fits perfectly for smash.

king dedede is a shoo in, due to his popularity at the polls.

sonic is the most wanted character, and yuji himself said that he would love to see a game with mario and sonic together.

ridley will most likely be in smash due to his popularity and the fact that metroid needs more characters.

diddy kong is pretty likely being that he showed up in a lot of games as of late.

We already have a topic for talking about the most likely candidates. It's called this whole room.
