That's not Ultima Buster, that's Sinspawn Gui. Ultima Buster is a very powerful optional boss in the monster arena.

Anyway. The very first thing you should do in the battle is have Auron use Power Break on him. After this, pay attention to his attack pattern. He uses Punch on his first two turns, then after that, alternates between Demi and Punch. When he's going to use Punch, bring in your strong characters (most likely Auron, Kimahri and Wakka). When he's going to use Demi, bring in weaker ones, since it can't kill them. Your first priority is to get rid of the head. Wakka's attacks, Kimahri's Lancet and Lulu's spells can all hit the head. Especially, when it starts moving suspiciously, attack it as soon as possible (any of those will work).

Once the head is dead, you can focus on the body. Have your strong attackers kill the arms, and once they're dead, attack the main body until they come back. When the arms are alive, you can still damage the body with Lulu's spells and Kimahri's Lancet, as well as any overdrives you get (the arms won't block overdrives, only Attack and skills).

Once Gui is down to 4000 HP, his attack pattern changes slightly. He may use Demi any number of times in a row he wants. However, he still will never use Punch twice in a row. Keep this in mind with your character choices.

If Kimahri has learnt Self-Destruct, use it once Gui's HP is less than triple Kimahri's max HP to quickly finish him off.

Note that the arms only reduce the damage from attacks. They don't do anything to other effects of attacks, which is why you don't need to kill them before using Power Break.

Don't bother with other status effects, as Power Break is the only useful one that he's vunerable to.

If you meen Sinspawn Gui it quiet easy.
Yust use your Aeons Overdrive and, Auron`s power break.
Use Lulu`s spells to hit the to face.(When he hold his arms in front). And it is good if lulu have lurn fira!
I think it is quiet easy now, BUT the first time I try, i think I use months to defit him.
Ultima Buster is wery hard! I havent beat him yet,.

Ifrit's overdrive should be able to take out the head and arms. After that, have Tidus cast Haste on Lulu and your strongest melee attacker (probably Auron, Tidus, or Kimahri; depending on how far along the Sphere Grid you've taken them) and wail on him. Bring in Valefor and use Energy Ray or Blast to finish him off.
