*ahem* Back to Super Smash Bros. Mellee...
My favorite in the first was Link, so he'll probably be towards the top of my list. But, since I like to play as all the characters (including Jigglypuff), I'm going to say that other potential Top Fighters in "Melee" will be Bowser (he's gonna rock), DK (he was great in the first), and Sheik (She's gonna fight like Link--I can just sence it!)
