Bowser's costume design was a true piece of art. I was dissapointed that he got so little camera time. *sigh*, in anycase, the sceen he was in was beautifully done.
I found it really interesting that he chose to explode himself with a ba-bomb, because when playing the actual game SSBB and the original SSB, a common thing to do when your damage is at a very high percentage (if you manage to get a ba-bomb) is to go kamakaze and explode yourself and the jerk who kicked your ass. I mean, you could aways try to throw it, but you may miss and still end up getting kicked off screen anyway. just saying.
