Captain Falcon is one of the first unlockable characters in the series, and the first I didn't know. He is the main star of the F-Zero racing series, which is one I never played much. Since he was the star of a racing game, he was the series' fastest character.
But his speed was nothing compared to his "Falcon Punch!". It's a dumb move, but I love it.
I used him a lot in Melee. Mainly for Falcon Punches again.
I didn't use him much in Brawl either. He did finally get outclassed in speed by Sonic the Hedgehog.
His Final Smash was decent I guess. He gets in his Blue Falcon race car and you get a chance to run over opponents.
