This really depends on the player. I've read walkthroughs stating that you had to be at least lvl 80, while I beat sephiroth myself on a much lower level. (Something around lvl fifty, if i remember it correctly). Some people are even able to beat him the moment he becomes available, after only 2 or 3 tries.
So the answer is that there isn't actually a given answer to this question. The higher your level, the easier it becomes. If you really have a lot of trouble dealing with him, you should read some walkthroughs or watch some videos about the fight. They can be a great help too.
defeat sephiroth, but you have to be at least on level 80 hes a ruff one
you need to be at least level 80 to try and defeat him, and make sure you equip plenty of potions and elixirs.
He is located at the Postern, and after you talk to him, go find Cloud. Sephiroth will now be in the Crystal Fissure. (RoxasKH2) and level up before you go to him.
After the 1000 Heartless Battle, go to the place after the area where you fought them. Press the reaction command "Approach" on Sephiroth. But beware, you must be at least Level 80 to fight Sephiroth.
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
i beat him when i was a level 20
You need to defeat level 20 of the arena for Terra
If you mean the keyblade Fenrir, Then you get it by beating Sephiroth at Hallow Bastion (Radiant Garden). A high level is recomended to fight him as he is the most difficult boss in the game.
In kingdom hearts 2, before your final battle with zemnas, go back to hollow baston (radiant garden is now what they call it) and go to the place where axel told you about zemnas. Setheroth should be there. A short video will play. Afterwards, the battle begins.****WARNING**** setheroth is very strong if you want to defeat him you better hold up on your final battle until your level is around the high 90's.
You don't have to be a certain level in Kingdom Hearts 1. You get Glide from Neverland. In Kingdom Hearts 2, you have to leveling Final Form.
Unlike the first Kingdom Hearts, the highest level that you can get in Kingdom Hearts II is level 99. This is why the experience bar no longer displays the next level.
Kh 2, the regular edition, no. KH final mix, yes all 13 organization members as well as terra this can be found in hollow bastion be warred all of the are of high level and power. and all have the same hp as sephiroth.
