"After sealing Hollow Bastion you can fight Sephiroth from FFVII. He is as hard as they come. Even if you are at lv.100 and have the Ultima Weapon, don't be surprised when he announces SIN HARVEST and you lose. Attack violently and use Ars Arcam whenever you can to prevent him from saying ALIMONIE which is less devastating than "sin harvest". Don't give up though every character has their flaws...except Sephiroth.

--

After sealing the Hollow Bastion keyhole return to Agrabah and head toward Alladin's house. Speak to the carpet and fight like hell because you will face off against the nastiest Heartless by far. Easier than Sephiroth?...a little but not by much." - MASTER

"I know how to defeat Ursula. First defeat Flotsam and Jetsam. Then attack the cauldron with magic. A flash will appear and stun Ursula. Hit her until she wakes up. If she revives the 2 eels ignore them. Defeating Ursula will earn you Mermaid Kick. " - Nathaniel rego
