Yeah, that's why I gave up on him. Plus, when Dusky and I were battling Tabuu or however you spell it, I kept getting knocked off by Tabuu's stupid butterfly wing attack and then with meta knight, I couldn't fly back up for some reason...
Taboo's (i don't know how to spell it either, I forgot...) butterfly attack can kill you instantly unless you use your aerial shield, but if you get knocked off it's real hard to get back on.
Dusky might have. I dont own the game. We kept getting so close x3
We found out that you are able to stay alive with his butterfly attack unless youre over about 50%. But you just have to keep pressing A. Dunno why, but it works 95% of the time. And I was at, like, 80% and I stayed alive a few times.
If you ever fight him again, try using Snake and Bowser. I found out that they do a whole lot of damage to him. It's how my brother and I beat him on our fourth try. You could also keep trying new characters until you find out who does the most damage to him and stays alive the longest.
