[Glitch]

Speaking of Colosseum, if you upgrade enough and get the Immortal armour, Czar is a pushover. seriously.
It makes you immune to all elements. I used Umaro and Celes (other characters would have been a liability if they died, etc) using Quick and a lot of megaelixers and he died....... eventually. ahaha.


Also:
Every so often you run into a boss with crazy defense and magic resist, so you can't do more than 100 damage. This is completely trivialized by Gau's "Lethal Wpn" rage. It has a move called "Missile" which does damage equivalent to a certain percentage of the enemie's overall HP, is non-elemental and works on any mob in the game really.
So while your guys are doing 50 damage, gau is hitting for 9999, and as he does less and less damage, you get a good indicator of how close the boss is to dying.
