1. Snake
2. Sheik
3. Ness
1. I use mostly the C4, hand grenades, and the remote-controlled missile not to attack, but to decrease the amount of options my opponent can take. By doing this, my opponent has less options to take and I can win without much thought. I do not win, my opponents just lost.
2. My old main back from the hay days of Melee. I am still getting used to the tweaked air dodging and modification of her down "A" in the air. That is mainly why I use Snake more. Oh, but like always, no Zelda. Because the transformation to Zelda takes too long, I cannot exploit Zelda's jumping ability when I am in dire need. Luckily for me, jumping in general is a lot easier anyway.
3. I scoffed at all of you when you were so sure that Ness would not be in Brawl. I laughed when you saw Luca's page and were discouraged, but I knew that more than likely it was a translation issue that led to negative thinking. Some of his tweaked moves are difficult to handle. But I will use Ness just to spite you. Using PK Starstorm in the air from the right side seems to make it more effective, otherwise his Final Smash blows.
