Umm actually it is impossible for him to be hurt. Go play the game again and You'll see. He takes zero damage. No get your team to level fifty equip them so they have whatever armour Sephiroth had at that point(Gold Armlet I think). Now see that you should still take damage. He cannot be hurt. But yet you can.
