I have just beaten him and i find that the guide really helped there are tons of websites out there so just type your question in on Google an you'll find loads of help. I had the ultima weapon on because of the mp hastega ability and i was at level 82. My shortcuts wear elixir, hi-potions, reflect and cure. You definitely need retailiating slash, high jump and areial Dodge lvl.2-3 and trinity. It helps to have guard, counterguard, aerial spiral and sweep, slide dash, hp haste, glide, quick run, leaf bracer and aerial recovery. He is imune to magic and his attacks are type weapon, fire, dark and non elemental so stock up on armor to protect you against these. There is lots of help out there and once you learn the patterns in his moves it is really easy. In fact is you type how do you beat Sepiroth in Kingdom Hearts 2 into WikiAnswers you will find that someone has already answered this question, happy to help!
you don't have to beat sephiroth to fight ansem I didn't. I think you have to go to hollow bastion to fight ansem.
He dissapears with Cloud
i did mine at level 56....i don't fight heartless or nobodies much..but anyways..56 is the best lvl...at the point on how you beat sephiroth
Thankfully, no.
You cannot get Mickey's Keyblade in Kingdom Hearts II.
on Kingdom Hearts 1 i have no clue but on Kingdom Hearts 2 after you beat sephiroth go talk to cloud and he will give you a keyblade called Fenrir
Get Kingdom Hearts 2. That's what I did. Or you can try and beat sephiroth and all those extra things.
I think you have to beat Sephiroth.
2 ways cheat via gameshark or just practice
Once you beat him, he goes away.
Fight.
You have to beat radiant garden/ Hollow bastion foor the second time and also space paranoids for the second time and then go where you fight the 1,000 heartless and keep on going down and he will be there
