Kingdom Hearts Final Mix

After finishing the Hades Cup, the fight against Sephiroth will open up to you. Mentally prepare yourself for this fight as it is quite the fight. Equip yourself with Elixirs and Megalixir as you will need it dearly for this fight. You might want to take this fight on around level 65-70 - the higher your HP/MP/Attack/Defense is, the better it will be for you. This is the hardest fight in the game right next to Unknown.

At the start of the fight when you attack him, you will notice that his health doesn't seem to go down. His health is so high that it goes beyond the limits of the game so don't pay any mind to this. Sephiroth's swings are fast and cover a lot of ground, if you want to approach him you'll have to do so from the air most of the time or by catching him when he jumps around the field. When he jumps or teleports around watch out for his Super Nova as it covers a lot of space around him and will more than likely catch you each time.

After you have finally gotten his health down one bar he will start to run around the stage as part of his movement, make sure you never take your eyes off him and continue to make sure you lock on to him when he leaves your sight. He will try to retreat away from you so that he can cast a spell that will reduce your health and MP right to zero (you won't even be able to use Leaf Bracer + Curage or Second Chance). When you see him stand in place, cover ground quick through dodge roll or superglide to interrupt the spell and prevent almost certain defeat. If you're too far to reach him you can buffer an Elixir to heal you right as you lose all your health and MP if you time the activation just right.

After getting his health down even more, Sephiroth will start to summon meteors to attack you, he is completely invincible when he summons them so you'll have to wait for the meteors to end and attack him quick. At this point he starts to teleport a lot and spam Super Nova, so start to use Aeroga more and be prepared to take some damage in order to get your hits in.

Be patient against him and he will meet certain defeat. After you have defeated him the trophy will unlock and you will no longer have to worry about "difficult" fights for the rest of the game.
