'''[[Saïx]]''' is fought as a boss in ''[[Kingdom Hearts II]]'', ''[[Kingdom Hearts 358/2 Days]]'', and ''[[Kingdom Hearts III]]'', and ''[[Kingdom Hearts Union χ]]''. 

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. 

In ''Kingdom Hearts III'', he and [[Xion]] battle Sora, [[Lea]], and [[Kairi]] at the [[Keyblade Graveyard]], but once Xion defects to the [[Guardians of Light]] and Roxas returns to turn the tide of battle, Saïx engages Sora, Roxas, and Xion in one last stand. A data replica of him is also an optional boss in ''[[Kingdom Hearts III Re Mind]]''.

==Strategy==
===''Kingdom Hearts II''===
Throughout this battle, Saïx's attack pattern is determined by a "Berserk Gauge" in the top-left corner of the screen. When the battle begins, the gauge will be full and Saïx will rise into the air and enter his "Berserk" state. The gauge will begin slowly emptying and once empty, he will revert to a calmer attack pattern, wherein the gauge begins filling again. Note that the burst of light that emanates from Saïx's body when he enters his berserk state can damage Sora.

While in Berserk mode, 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. While in this state, Saïx's attacks have a large range and high power. 

[[File:Versus Saïx KHII.png|right|thumb|Saïx battles Sora, Donald, and Goofy within [[The World That Never Was]].]]
In addition, he is invulnerable to normal attacks and extremely resistant to magic attacks. However, Sora can pick up his thrown claymores with the [[Reaction Command]] "Berserk", then use the Command "Eclipse" to slam Saïx into the air and finally "Magna Storm" to attack him rapidly. If "Magna Storm" connects with Saïx, his Berserk gauge immediately empties and he reverts to his "normal" state.

While in this state, he walks slowly and attacks with slow, but powerful combos. At this time he is more vulnerable to damage, but he can still defend himself, so it's best to use [[Guard]] when he attacks or deflect his attack with one of Sora's own, to make him drop his claymore. This will cause him to cease attacking for a while, as well as give Sora the opportunity to use Reaction Commands and attack with the dropped claymore for massive damage. At times, Saïx will stand still and raise his arms to hasten the speed the Berserk Gauge fills. As Saïx loses more health, the Berserk Gauge fills at a much faster rate.

As long as Sora uses Reaction Commands to revert Saïx's transformation as soon as possible, he is not an overly difficult opponent. If in a tight spot, avoid Saïx's berserk attacks by gliding or dashing away, healing when necessary. Be cautious if using Drive Forms, as [[AntiForm]] is more likely to activate due to the nature of battling an Organization XIII member. Using [[Final Form]] is a big help if accessible, while Saïx is in his normal state.

====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 for a short period. Sora can use a finishing move to interrupt Saïx' charge early, so it is recommended to remove any Combo Plus abilities prior to the battle.

[[File:Versus Saïx's Replica Data KHIIFM.png|thumb|right|Saïx's Replica Data appears before Sora in the [[Garden of Assemblage]].]] 
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 that can be dealt. 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!" desperation move (which he uses at full berserk when below 60% HP); it is at this time that he is truly invincible and Sora must stay away. 

Saïx may also begin his "Move aside!" combo, provided enough distance is put between Saïx and Sora, simply stand in place and wait for his claymores to drop close by. The third thing that will happen is Saïx will begin to run towards Sora, once close Saïx will either perform his "Begone!" combo or leap into the air and perform his large shockwave attack. If not Reflected, do not count on grabbing the large shockwave claymore, by the time Sora is 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!" desperation move since it requires a full Berserk bar to perform.

The Lunatics that Saïx throws disappear very quickly, so get to them quickly by using Dodge Roll or guarding the attack that launched them with Reflect. Unlike in the original battle, Sora will be invulnerable while holding a Lunatic, and the "Berserk" Reaction Command after grabbing one becomes available almost instantly.

After breaking Saïx's berserk state, it is pivotal to guard in order to block his attacks, as they can still deal heavy damage and will allow Saïx to call to the moon to charge his Berserk gauge faster. The "Magna Storm" Reaction Command will still reset Saïx's Berserk gauge in the Data Rematch, but the dropped claymores vanish much faster and the window to use Magna Storm after seizing one is shorter.

===''Kingdom Hearts 358/2 Days''===
Saïx's main tactic is his berserk mode, which he starts almost at the exact start of the fight. Don't move towards Saïx until he activates his berserk state, as being near him when he activates will deal damage. In this state, his Claymore has its signature extended white edges. He himself has an aura of blue light surrounding him.

He has a diverse range of attacks and combos at his expense. He has a few close range combos in which he swings his Claymore around. If Roxas gets caught by one attack, he may get drawn into the rest of the attacks he does for that combo. Saïx has five types of combos.

The first one is his most common attack, where he swings the Claymore for about 2–3 seconds ending in a spin. There is about a 2-3 second gap until his next combo, so get a few quality strikes in before retreating to avoid his next move.

The second pattern is where he also swings his Claymore around, but there are distinct differences between this and the first. After about four seconds, Saïx will swing the Claymore down in a straight, vertical slash. That's a hint to escape into the air, because he will follow up that slash with another of the same slashes, but it will produce a blue energy wave in its direction. Immediately afterward, he will jump in the air and throw down his Claymore, which will strike down anything in its vertical path (including the air) and produce an 360 shockwave which will hit anything on the ground that is near it, even while blocking. This will open up him to a few strikes from the Keyblade. However, Roxas can't use the Claymore to hit him and the damage done is the same as usual in his berserk defense. After 2–3 seconds, he will summon his Claymore to him and start attacking again.

The third is a simple two strike move with one swing and spin. This move takes about 1 second to execute and the traditional 2-3 second gap after.

The fourth is a mix of the second and third with the third coming first. Right where Saïx should throw the Claymore, he starts the second combo. After this, again comes the 2-3 second gap.

The fifth is a truly berserk state where Saïx moves in circles, swinging wildly.

Another of his attacks is where Saïx teleports to the top of one of the towers in the room. After another 2–3 seconds, he will leap over Roxas and drop down to smash him. On occasion, if Roxas moves right after he leaps, he will stop near the ground and teleport above Roxas to smash him again. Either way, he will immediately follow up with a combo.

After he has been dealt a sufficient amount of damage, his aura will "break" off and he will slide backwards, where he will become inanimate for a short while. That's where Roxas should hit him with everything he's got: magic, critical hits, combos, anything. After that short while, he will start to defend himself with blocks, jump strikes, and three hit combos. It's important to still prioritize defense, and Saïx is still a danger even when he's not in his Berserk Mode, as he still will not stagger from attacks. Soon after, he will restart his aura.

Saïx's attacks and Aura can randomly inflict Silence, preventing the use of magic. So be wary of getting hit or too close to him. His Aura also provides extra defense against both magic and attacks. Attack whenever possible: Set up Blizzaga to hit him when he's attacking and Thundaga while he's on the tower. If Roxas uses Thundaga and breaks Saïx's Aura while he's on the tower, he will slide back and fall off the floor. For a while, he will continue falling, but he will teleport behind Roxas. Try not to block any of his attacks unless Perfect Block is linked. Saïx may break through the block if Roxas is pushed back. Glide, Dodge Roll (especially Block Dodge Roll), and Haste are very useful for avoiding damage.

===''Kingdom Hearts III''===
[[File:Versus Saïx (Berserk) KHIII.png|thumb|right|Saïx fighting against Sora, Roxas and Xion in the Keyblade Graveyard.]]
Saïx is one of the bosses at the Keyblade Graveyard. In the first part of the fight, in which Saïx fights alongside Xion, Sora has Lea and Kairi as allies. At the start of the fight, Saïx uses '''Berserk''' to enter Berserk Mode. Thereafter, he switches between Normal, Berserk, and Blue Berserk Modes depending on the status of the Berserk Mode. When he reaches Blue Berserk Mode and uses '''Blue Berserk Burst''' for the first time during the first part of the fight, the battle is interrupted by a cutscene in which Xion defects to the Guardians of Light, Roxas appears to fight alongside Sora, Lea is injured and left to recover, and Kairi is abducted by Xemnas.

After the cutscene ends the second part of the fight begins, where Saïx is fought alone and Roxas and Xion serve as Sora's allies. In the second battle, Roxas is invincible and will not sustain damage. He also inflicts powerful attacks, which means Sora can focus on dodging Saïx's attack while waiting for Roxas to weaken Saïx to 1 HP before moving in to finish the battle.

Saïx has the most amount of health out of all the Keyblade Graveyard bosses. His Berserk Gauge will continuously fill from empty to yellow, where he enters Berserk Mode, and finally to blue, where he enters Blue Berserk Mode. Once in Blue Berserk Mode, the progress of Saïx's Berserk Gauge reverses, going from blue to yellow to empty, with each time he is hit or flinches reducing the gauge proportional to the amount of damage taken. When his gauge falls to empty, he becomes incapacitated, making him completely vulnerable to attacks until the Berserk Gauge fills back up to yellow.

In addition to retaining all his energy attacks in his fights in the previous games, Saïx also becomes able to use melee attacks in his Berserk State as he does in his normal form previously. His second Berserk State greatly augments his attacks as he gains access to several Claymores that he can plant on the ground before exploding when he slams his Claymore to the ground, launch several Claymores at once and create nearly omnidirectional shockwaves by slamming all the Claymores into the ground.

===''Kingdom Hearts III Re Mind''===
Saïx's fight is revisited in ''Kingdom Hearts III Re Mind''. 

The first phase is identical to the base game. An additional phase is added between the first and second parts of the fight, in which the player plays as Roxas against Saïx and Xemnas. Roxas has Xion and Lea as allies, and can perform the [[Thinking of You]] [[Team Attack]]. After some time, Xemnas leaves the fight. The final phase is identical to the second phase in the base game. Before this phase begins, the player can choose to play as Roxas with {{button|l2}} or Sora with {{button|r2}}.

====Data Rematch====
[[File:Versus Saïx's Recreated Data KHIIIRM.png|thumb|right|Saïx's recreated data engaging in combat against Sora's data.]]
Saïx's data rematch is less upgraded compared to the other Real Organization XIII members, but he is still among the strongest of them. Several of his attacks can Stun Sora, so it is recommended to equip [[Stun Protection]] through equipment such as the [[Nano Gear]] Keyblade.

He has two Berserk modes, the first entered when his Berserk gauge turns yellow, and the second entered when the gauge turns blue.

When the fight starts, Saïx rises into the air, emits a small shockwave, and enters yellow Berserk. He will then start with a feint swing, a second swing that breaks Sora's guard, and a third swing. He will pause and rush in with a fourth swing, then finish with a spin. To deal with this, block the second swing, then risk dodge after the guard break and attack. If Sora misses this punish and gets hit, quickly recover and block the two follow-up hits, then reprisal the spin for a chance to attack.

Saïx will slam the ground twice, creating purple fissures that cannot be blocked, and then perform the same swing combo as before. The first slam's fissures will actually miss Sora if he is in Saïx's line of sight, so dodge roll the second wave, then block the guard break hit, risk dodge, and attack.

Saïx will jump and throw a spinning claymore, then fall to the ground. Dodge or Airstep to him and attack while he is empty-handed in the air. Note that the thrown claymore cannot be blocked, and if Sora is hit by it, he will be stunned. This is also the case for all other spinning claymores that appear during the fight.

Saïx will sometimes use two fissure slams before throwing his claymore, which creates a third fissure slam instead of the stunning spin. Again, Dodge or Airstep to him and attack while he is empty-handed in the air.

When Saïx's revenge value is hit while in yellow Berserk, he will hold his claymore in a defensive stance and will flip into the air three times. After a pause, he will then perform two spins. This maneuver is very similar to the Eclipse and Magna Storm Reaction Commands from ''Kingdom Hearts II''. Block the first three hits, then pause and block the last two.

Saïx's Berserk gauge will steadily fill blue during yellow Berserk, and will fill faster as Sora deals damage. Once it is completely blue, Saïx will rise into the air, emit a large shockwave, and enter blue Berserk. The shockwave will not damage Sora, but will knock him back significantly, so dodge roll or guard to avoid it. Saïx's move set will completely change from yellow Berserk, and will overall be significantly more dangerous. 

If Saïx starts by throwing several claymores on the ground and slamming the ground, he will follow with a rushing uppercut, perform a dash that creates purple fissures, do two front slams that create purple fissures, and finally rise into the air with claymores floating around him and slam the ground again. He is vulnerable to attack during this final slam. Dodge the initial slam, uppercut, dash, and two front slams, then dodge toward him during the final slam and attack. It is also possible to guard the second front slam, though it will break Sora's guard, so risk dodge and attack to hit him just before the final slam.

If Saïx jumps and throws a spinning claymore, four more spinning claymores will arc around him and approach Sora. Saïx will then fall to the ground, do two front slams, and finish by rising into the air with multiple claymores floating around him and slam the ground. He is open to attack after the throw, however the four other claymores make it very risky to approach him. One way to handle this is to Airstep the instant that he throws, so that the other claymores cannot approach, but the timing is tight. Another approach is to Airstep, attack, stop the combo short to air slide the four claymores, then continue to attack. Otherwise, run and dodge the four claymores when they get close, dodge the two front slams, dodge the final slam, and finally attack.

If Saïx starts with a dash that leaves purple fissures, he will do four of these dashes before throwing several claymores on the ground and slamming the ground. He is vulnerable immediately after slamming the ground. Carefully dodge the four dashes, then dodge toward him during the slam, and attack.

If Saïx stands still on the ground and yells, he is recharging his Berserk gauge. He is vulnerable to Blizzard during this move, so cast one at him to stop the gauge recharge, and continue the combo to attack. 

Saïx's Berserk mode will gradually decrease over time, but will decrease more rapidly as Sora deals damage. When the gauge has been completely depleted, Saïx will be stunned and open to attack for a several seconds as the gauge fills itself yellow again. Once the gauge is fully yellow, he will enter yellow Berserk again.

While in blue Berserk, if Saïx starts spinning and generating several small shockwaves on the ground, he is performing his ultimate attack. He will glide along the ground, creating shockwaves around the arena, occasionally generating a spinning claymore in the air that flies toward Sora. When he gets close to Sora, he will do a quick front slam that creates fissures before continuing his assault. The move will end shortly after the fourth spinning claymore flies at Sora. To avoid this, Sora should stay on the ground in one place and carefully watch Saïx's movements - he will usually be on the other side of the map and not be a threat. When a spinning claymore appears, be ready to dodge it on the ground. When Saïx himself gets close, jump and then air slide towards him to avoid his attack. If Saïx and a spinning claymore approach simultaneously, which often happens with the fourth one, air slide toward the claymore instead.

After using his ultimate attack, Saïx will have some new combos in both Berserk phases.

During yellow Berserk:
* Saïx will add a rushing strike before his swing combo. This puts him close enough to Sora that his feint attack will actually hit. Guard the rush and the next two hits, risk dodge when Sora's guard is broken, then attack. If this opportunity is missed, quickly recover and Saïx will add in another rushing strike before swinging again and doing his spin. Guard and reprisal his spin, then attack.
* Saïx will add a rushing strike after his two slams, but before starting his swing combo. Dodge the second shockwave, then handle the enhanced swing combo the same as before.
* Saïx will also add a rushing strike before throwing a spinning claymore. Block or dodge the rushing strike, then dodge the claymore and attack him while he is empty-handed.

During blue Berserk:
* When Saïx starts the combo with throwing down multiple claymores and slamming the ground, he will follow with one dash and then his uppercut, instead of his previous uppercut-then-dash. The combo will end the same way, with two front slams and a final slam with claymores floating around him. Carefully dodge the mix-up, then handle the rest of the move the same as before.
* When Saïx starts the combo with spinning claymores, he will add an uppercut between the two front slams after falling to the ground. The combo ends the same way, by slamming the ground with multiple claymores floating around him. The move can be handled the same as earlier.
* When Saïx starts the combo where he dashes four times, he will follow the four dashes with a front slam, dash two more times, and finally finish by throwing several claymores and slamming the ground. He is vulnerable during the final slam. Dodge the barrage of attacks, then dodge toward him during the final slam and attack.
