-THE KEY TO WINNING THE BATTLE IS WHEN SHE USES AN ATTACK THAT CAUSES ZOMBIE DON'T CURE IT EVER.

She's tough and has three forms, the first form is the easiest, just be sure to have hatsega on everyone and have out Yuna, Tidus and Auron. You might need to level up a little too. It helps a lot to have Yuna use holy...but if you don't have it and want to cause quick damage, use Rikku and have her throw a few X-potions at her, otherwise just hit her everything you got.
She switches to her second form which is far more powerful and she has plenty of new attacks including one that inflicts Zombie, keep it NEVER heal it because after you defeat her second form she quickly goes into her hardest form yet and uses an attack that kills all characters...however if they have zombie they're alreayd dead and can't be affected! She'll use it a few more times during the battle so don't heal zombie and keep using X-potions, attacks and everything you got.
