Equip Fire Ring to all character to half the effect of One Billion Degree. Then, change to Dark Ring to half the effect of Dark Nova. At the interval, use Marivel Sleep (make her luck to Best). When he snorts, give all your best non-elemental attack. When his HP is low, he will use Impact Bomber that will do about 6000 HP damage. Include Tim in the party and cast First Aid every turn. You will get the best Gear in the game, the SheriffStar.
