Game:Saïx

Saïx is fought as the third-to-last boss in Kingdom Hearts II and Kingdom Hearts 358/2 Days. In Kingdom Hearts II he is the last of the Organization XIII members to fall before Sora faces Xemnas, attacking Sora near the top of the Castle That Never Was, in his chamber overlooked by Kingdom Hearts. In Kingdom Hearts 358/2 Days he attacks Roxas when the Nobody tries to leave the Organization.

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 this time he is very vunerable to damage but can still defend himself, so it's best to use guard when he attacks to make him drop his claymore and cease attacking for a while, also you can parry his attack to make him drop it. 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.Try not to use Drive Forms too much, you might get AntiForm.

Do note that Saix's defense increases when he is in berserk mode, making powerful hits an insignificant amount of damage.

Kingdom Hearts 358/2 Days
At the start of the battle, immediately Lock-On to Saïx. Saïx attacks in a pattern, and you can usually see it coming, so utilize your Glide and/or Dodge Roll abilities at the beginning. He will mostly run around coming after you as you glide away, he will use a combo and, as soon as he is finished, attack from behind. Land a few hits and then continue to run, rock and Roll away, specially if you have the Dodging Deflect panel installed. On occasions he will vanish to an area in the distance, this is when you have to stay in the air using Air Slide, Glide or Float (linked to High Jump), because he leaps down from his perch and creates an area effect that can be quite annoying, since it might Silence you (prevent you from using Magic), though this can be prevented by using Cura before this attack or using a Panacea. Continue the avoiding strategy, and he should go out of his Berserk form, that is when you unload on him. Still you must avoid his attacks to the best of your ability, to reduce damage and to keep you from the brink of death if he hits you in Berserk. He has another combo in which he knocks you back and throws his claymore at you, which again, creates an area attack that deals fairly good damage. One attack he uses if he hits you, is he swings and throws a blue projectile across the ground, stay as far away from this as possible, it is Silencing and annoying. So simply avoid him and wait until he finishes combos. His combos usually start up about 2-3 seconds after he ends his last, so hack away for about a second and then continue to run.

Just like in Kingdom Hearts II, Saix's defense in increased in Berserk.

There is also a Mission Mode version of this battle in which you fight the dark version of Saïx, Anti-Saïx. The strategy to this boss remains the same with a few minor changes.

Kingdom Hearts II Final Mix Data Rematch
Saïx's Data Rematch begins slightly differently from his first encounter. His Berserk bar will begin empty and he will immediately call to the moon and start charging it, to break this charge you must use a finishing move so it is recommended to unequip any combo pluses prior to the fight, negative combos are not needed although it won't hurt you in this fight.

Once Saïx enters his Berserk state the battle becomes purely survival and waiting for him to drop a claymore, Saïx will take damage in his Berserk state but it is not without risk because of the large amount of damage he can dish out at any time. The best strategy is to keep as much distance between Saïx and Sora as possible and look for one of three things to happen: Saïx will stand in place and use his "All shall be lost to you!" super combo (which he uses very often in this fight), it is at this time that he is truly invincible and you must keep Sora away. Saïx may also begin his "Move aside!" combo, provided you put enough distance between Saïx and Sora you can simply stand in place and wait for his claymore to come to you. The third thing that will happen is Saïx will begin to run towards Sora, once close Saïx will either perform his "Begone!" combo or he will leap into the air and perform his super shock wave attack. Do not count on grabbing the super shock wave claymore, by the time you are close enough it will vanish and Sora will be close to Saïx and vulnerable. After every one of his combos, he will recharge his Berserk bar and the only way to stop this is to attack him. However, this comes as a risk because he will attack back with one of his combos except his "All shall be lost to you!" super combo because he needs a full Berserk bar to perform this.

After breaking Saïx's berserk state ensure to guard in order to block his attacks when you see them coming, they can still deal heavy damage and will allow Saïx to call to the moon to charge his Berserk gauge faster. Using the Magna Storm command does not reset Saïx's Berserk gauge in the Data rematch. This fight is simply rinse and repeat once you get the rhythm.
