My mains in Brawl are Snake, King Dedede, and Wolf. Lucario and Kirby are rather borderline, but I considered them mains as well for now. Ganondorf is my old bottom tier main, who I'll often play (though I won't use him in any important matches)
Back in Melee, even though I don't really play it anymore, my sole main was Ganondorf (he was so much better in Melee). He was beyond everyone else for me in it. Secondaries of Melee were Captain Falcon (who also got screwed over in Brawl, though not as badly as Ganondorf), Falco, and Bowser.
