I beat him.
I was level 92 though.... I was too busy training my Forms. I had Forms maxed(doesn't help, except for the Double Jump, High Jump, Glide, and Quick Run), Put Elixirs as L1 Triangle Command and Reflega or w/e as Square Command, I HAD Berserk Charge Ability, but it doesn't help as much because you have to kill him in a finishing blow. Also, don't have abilities that increase your Drive or Form or Magic or Limit stuff because they don't work at all.
Watch Reaction Commands carefully, because if you don't Block, you will have to use an Elixir or Curaga, or Hi-Potion, and that is just a waste when you could just press Triangle to Block.
Berserk Charge Ability helps because when he uses HP/MP to 0, he will use the Attack where you Reaction back with block, then you can just Attack constantly. Berserk Charge ability states that you can have an unlimited combo as long as your in MP Charge mode. So your MP is charging and you have unlimited Combos.
Reflega is VERY Helpful! If you just finished your combo and he disappears, just use Reflega 3 times when he attacks you, and he will get hit with the reflect, giving you enough time to attack back and hurt him even more.
I didn't kill him with a Finishing Combo, I killed him with Reflega's reflect.
