How do you beat xigbar in kingdom hearts 2

Smack him around with the strongest keyblade you have, and when you hear him yell, "Let's see you dance!" that is your cue to run around in a circle to avoid the bullets. It would be smart if you healed with A mega potion or Curaga as fast as you could first though. Also if he is shooting bullets at you, try to send them back at him by blocking them.
