Ok now I know for sure. All of Bowsers attacks can destroy almost all projectiles in the game except for his D-air, flames, Down B, and grabs (Klaw can destroy projectiles though). Heres a big list:
Everything but Lasers (**** those blasted lasers!), PK flash (I think, someone needs to confirm), and Pikachu's/Pichu's Thunder (Down B).
Somebody confirm this?
I just like to plow through Samus's attacks instead of dodging. Because you can't move as thoroughly in the air as you can on the ground. And in the air you are more susceptible to a hit if you can't air dodge or fortress, hopefully they won't combo you.
I am actually more comfortable with Samus than a Jigglypuff. I know Jigglypuff dies in like, 1 hit, but they are too agile for me.
