It's difficult for me to pick just one, since I play more than half of the characters....but overall, I would agree that Snake is the most fun to play.

But of course, I love Wolf and Ike too...basically all of the characters people hate. lol

I like both Toon Link and Kirby, so whenever I'm Toon Kirby, I go insane.

SONIC FANBOY lol

Sonic drives me insane. lol

Samus(with suit) is my favorite

I voted Lucario, but I regret it
I would have to say, Sonic, Ike, or Marth.

(Marth is my favorite, not best but favorite because hes in fire emblem DS)

I would have to say
Ike and yoshi as favorites
Then for fun it would be
ganon
zelda
wolf
c. falcon
luigi
snake
wario

Lucario
Pikachu
Kirby
Marth
Toon Link

My favorites are:
Ganon and Snake really

Other Mentionns:
Captain Falcon
Meta Knight
DDD
Link
ROB
Zelda/Shiek
Kirby
Falco
Ike
Toon Link
Olimar
Luigi

Yes thats a lot of characters.

Fox McCloud is my favorite. I think he's very under-appreciated.

The only thing good of his is his Shune po. My favorite is Zelda/Sheik. Im The bomb with them, but unbeatable with Link.
