Game:Saïx

Saïx is fought as a boss in Kingdom Hearts II. The last of the Organization XIII members to fall before Sora faces Xemnas, he attacks Sora near the top of the Castle That Never Was, in his chamber overlooked by Kingdom Hearts.

Kingdom Hearts II
When the battle begins, Saïx will rise into the air and enter his "Berserker" form. In his Berserker form, Saïx attacks very quickly with powerful attacks, slamming his claymore into the ground to unleash large shockwaves of energy. He also throws his claymores at Sora, unleashing streams of energy when they impact. During his "Berserker" form, Saïx's attacks have a large range and high power. However, the player can pick up his thrown claymores and use them to attack using the Reaction Command "Berserk". Once the claymore is in Sora's hands, the player can use the Reaction Command Eclipse to slam Saïx into the air, then use Magna Storm to attack him rapidly.

Once hit by Magna Storm, Saïx immediately snaps out of his Berserker form. However, a bar in the corner of the screen will begin to fill, and once full Saïx will change back. Until that time he walks slowly and attacks with slow, but still strong combos. At times, he will even stand still and just raise his arms to hasten the speed the Berserk bar refills. As Saïx grows weak, the Berserk bar refills at a much faster rate.

As long as the player uses the Reaction Command to revert Saïx's transformation as soon as possible, he is not an overly difficult opponent. In Berserker form he is invincible to damage except from the Reaction Command, but outside of Berserker form he is almost helpless. The key is countering his Berserker form quickly, as if the player cannot, Saïx cannot be harmed until his Berserk bar depletes on its own.

Kingdom Hearts II: Final Mix+ Data Rematch
Saïx will rise into the air and enter his "Berserker" form just as in the original battle, but with a longer duration. The Berserk bar hardly ever depletes. Saix can still be harmed, however - either using Reflect or a Limit command with Donald or Goofy (preferably Comet with Donald). It is also remarkably hard to grab one of Saïx 's thrown claymores as he constantly emits shockwaves with very few pauses, so the player cannot count on the Reaction Command very much.

As long as he lets Saïx's guard down using Reflect, evades the shockwaves and heals when necessary, Saïx will be defeated. However, be forewarned: this battle is a tedious one.
