Ike and Marth are my mains in brawl (I am equally good with both). So is Ganondorf and Wolf... oddly enough. I tend to be better with heavier characters, with the exclusion of Marth and sometimes Captain Falcon.
I play Sonic too, but only for the lawls xD
I am pretty good at playing against other people when the stage in in my favor xD I fought against a level 9 Ike (he was out for blood, mind you) while I was playing Marth. Close match, I'll give you that. xD I play againsts some of my other friends and things get pretty heated. haha
