I'm trying to finish the Subspace Emissary in Super Smash Bros. Brawl. I've been stuck on the boss battle against Tabuu (in normal and easy modes). I know the secret to one of his moves, the one with the energy blasts, you have to sidestep or roll. Although I can never seem to get the timing correct, or even perform the correct maneuver. I had a friend who managed to dodge that attack several times by pressing random buttons, but that hardly helps because it never works for me.
I've gotten his health bar a little past two thirds of the way before, but it was that repeated move that took me out. Recognizing his other moves and dodging them are fairly easy, but that single move always kills me. If anyone had any tips, it would be really appreciated.
