What is the best way to defeat Cerberus on Kingdom Hearts 1

To defeat Cerberus, you might want to consider jumping on his back and attacking the heads when they rise, and leave head-on fighting to your allies. If you have aero, use it if you get stuck in front, and if Cerberus uses the move where black holes attack you from under, jump allthe way to his tail. Have extra MP? Use thunder on him!
