How do you beat the cobra heartless in kingdom hearts 1

ok so at the start of the thing he does alot of melee attacks that dont require any skill just keep your health up and the keblade swining. when he goes into the air and spins vertically you have to dodge roll either to the left or the right qickly. and when he spreads out and spins you need to have double jump equipped and jump over him. also when he goes into the aura ball hit the s*** outta him so he will drop MP bubbles so you can use magic on him. Mostley just level up and everything will be okay
