Follow this up with a quick combo before it rises, once it does rise into the air, repeat the process until your victorious. Now, to defeat the Heartless threat!

After Xigbar, the real target shows up: the Guard Armor. Brace yourself for a long battle if your not fast. After the Guard Armor is defeated, RTC.
