Myth: Samus has no kill moves.
Truth: She ha-... oh wait. Never mind.
No really, though, she has her bair, dtilt, and fsmash (and dsmash, kinda). The issue with the fsmash is that it's too slow. The dsmash, too. The bair is good if you can sweet spot it, but you can set it up all you want and they'll just airdodge. The dtilt is the only viable kill move, and frankly, it doesn't kill at low enough damage by my standards.
Myth: Snake's broken.
Truth: He's not broken. He's just really really really really really really really really really really really really really good.
Myth: Bowser mainers in Brawl like Brawl Bowser over Melee Bowser.
Truth: I would say a good portion of Bowser mainers (who were also Bowser mainers in Melee, of course) prefer the Melee one. I know I do for sure.
Myth: Diddy Kong is nothing without his bananas.
Truth: While the bananas are a big part of Diddy's game, he has a whole lot else going for him. His dash attack has no lag afterwards. His fsmash is pretty **** strong. His fair is a great aerial, and his SHbair can almost WOP. His recovery is insanely good. Oh, and he can hump the other characters face.
Myth: Maining Random is good.
Truth: No, maining Random is awesome. Random is broken.
Actually, I'm trying to get there right now. I've spent decent amounts of time using: Pikachu, Luigi, MK, Snake, Diddy Kong, Bowser, Samus, Fox, Falco, Marth, Ike, Dedede, and PT (all 3 equally).
