Editing Saïx

In the original Organization, Saïx served as the second-in-command to [[Xemnas]] and the secondary antagonist of ''[[Kingdom Hearts II]]'' and ''[[Kingdom Hearts 358/2 Days]]''. Fittingly, Saïx is the second-to-last member of the first Organization to fall. Along with all other original Organization members in ''Kingdom Hearts 358/2 Days'', Saïx is a playable character in [[Mission Mode]].

{{Q|Which would rather suffer the loss of? Some make-believe friendship? Or a real one?|Saïx to Axel}}

Along with [[Xemnas]], [[Xigbar]] and [[Vexen]], Saïx oversees the [[Replica Program]]. When [[Roxas]] is brought into the Organization as its thirteenth member, Saïx suggests the boy keep a diary to help him focus as his mind is mostly blank.{{storylink|Day 7: Entry 1}}

Once Sora defeated [[Ansem, Seeker of Darkness]], Saïx chooses [[Marluxia]], [[Larxene]], [[Vexen]], [[Lexaeus]] and [[Zexion]] to be the group to conduct memory experiments with [[Naminé]]'s powers at [[Castle Oblivion]] to prevent them from interfering of his and Axel's plans.{{storylink|Day 28: Dealing with the Traitors}} When reports of treachery at Castle Oblivion arrived, Saïx sent [[Axel]] to deal with it. Saïx assigns Roxas to carry out missions with Xion.

 

Soon after, reports came back that everyone at Castle Oblivion perished; doubtful Axel is gone, Saïx began planning to cover for his absence.{{storylink|Day 51: Measures Must Be Taken}} When Axel returns, he reveals to Saïx that he failed to find the [[Chamber of Waking]] to give them leverage over Xemnas.

 

Over time, a rift forms between Saïx and Axel, as he spends more time with Roxas and Xion. One day, Saïx confronts Axel, telling him not to get attached to them. He begins pondering if their past even matters to him anymore, having grown jealous of Axel's newfound friendships.

Sometime after Xion flees the group after discovering her origins, reports of Riku being spotted in Castle Oblivion has Saïx send Roxas and Axel to eliminate him, leading to the revaluation that Xion is now his. After Axel is able to retrieve Xion, Saïx taunts him by asking if he had to choose to save either Xion or Roxas. He then poses his real question: would he risk their genuine friendship over one that cannot exist between Nobodies. Saïx reminds Axel of their real plans, invoking Axel's human name to remind him of its importance.

 

With Roxas getting weaker from Xion sapping his strength, Saïx plans to them fight to the death as the Organization needs a useful Keyblade wielder. He sends them separately to [[Halloween Town]], secretly causing both to see the other as an [[Orcus]]. However, Axel intervenes and snaps them out of the spell. By this point, Saïx dismisses his previous plans with Axel as "just an idle fantasy".{{storylink|Day 356: Unforeseen Events}}

He meets with Xemnas and Xigbar regularly to discuss Xion, only to be told that Xion's sense of self is due to her trapping Sora's memories within herself. When asked about the [[Organization XIII Device|device]]s, Saïx states they will be ready in a few days. However, when Xion is on a mission with Xigbar and Axel, she knocks Xigbar out and escapes. Xemnas, Saïx, and Xigbar reveal Xion's origins as a replica and task Axel with finding her. Saïx sends Roxas to put up a device in the [[Agrabah|Lamp Chamber]].

The next day, Roxas decides to leave the Organization to find Sora for answers; Saïx attempts to stop him but loses. Weakened, Saïx looks to the moon, wondering when its strength will ever be his.

Saïx and the surviving Organization members to taunt Sora at [[Hollow Bastion]]. Upon the Organization's return to discuss their plans for Sora, Saïx expresses his doubts on Sora's usefulness of having a pure heart and states that those who have lost their "true purpose" will inevitably destroy themselves before Xemnas dismissed them.

Saïx later manages to track Axel down and take Kairi from him as a hostage for the Organization.

Upon Sora's second visit to [[Twilight Town]], Xemnas sends Saïx to confront Sora, leaving him confused and frustrated to further their goal. Saïx warns Sora that Axel has betrayed the Organization and is attempting to turn Sora into a Heartless. Saïx then leaves to report to Xemnas and asks about Axel, who merely mocks Axel's desire for friendship.

During the [[Battle of the 1000 Heartless]], Saïx stops Axel from revealing the Organization's plans to Sora, forcing the traitor to flee. Sora pleads with Saïx to take him to Kairi, and upon seeing Sora's devotion to the girl, Saïx uses the opportunity to bend Sora's anger to suit his own needs, convincing Sora to destroy more Heartless to continue building [[Kingdom Hearts]]. [[Maleficent]] appears, declaring Kingdom Hearts will belong to her. She summons [[Soldier]]s to attack, but Saïx has [[Dusk]]s destroy them. After Maleficent sacrifices herself to defeat the Nobodies, Saïx summons his Heartless once more and resumes his attack on the party. As Sora continues to extract hearts from the Heartless, Saïx departs in a corridor of darkness.

Saïx updates the Organization when concerned that Sora's newfound knowledge of their plans will only make him harder to control. His concerns were brushed off by Xigbar, who claims that it does not affect their goals since Sora will continue to destroy the Heartless to help those in need.  

After Axel's demise, Saïx meets with Xemnas, Xigbar, and Luxord. Saïx contradicts Luxord's statement on Axel gaining his existence back, berating Axel's sacrificial actions as he believed Axel died for nothing. Xemnas, while agreeing that Axel's actions were foolish, sees it as an opportunity for Roxas's possible revival.

 

 

Elsewhere in the castle, after [[Luxord]]'s defeat, Saïx awaits Sora, Donald, Goofy, Riku, and Kairi in a room with a direct view of Kingdom Hearts: Addled Impasse. He calls Sora by the name of "Roxas", saying only he could have made it this far, though Donald vehemently states Saïx is wrong. Saïx doesn't care, stating: "Different name, same fate." Using his claymore, Saïx creates a potent shockwave with sheer strength, pushing Kairi and Riku behind a barrier. With them taken care of, he confronts Sora, Donald, and Goofy for the final time. He finally lets his outer decorum slip away. Under the influence of the moon, he becomes savage and unrestrained, truly a model for his Berserker Nobodies.

 

However, despite the incredible power and abilities he drew from the moon of Kingdom Hearts, he is overcome. Defeated and mortally wounded, he limps away from Sora to the ledge overlooking Kingdom Hearts, asking it where his own heart is before he fades back into darkness.

[[File:Seven Lights, Thirteen Darknesses 02 KH3D.png|thumb|Saïx charges at Lea to prevent him from escaping with Sora.]]

Upon being reborn as [[Isa]], Saïx is taken by [[Braig]] and [[Young Xehanort]] to be made a part of the [[real Organization XIII]].{{storylink|Destiny}} Wanting to atone for his mistreatment of Axel and Roxas, Isa agreed to rejoin the group and became Saïx again to house a fragment of [[Master Xehanort]]'s heart.{{storylink|Kingdom Hearts III}}<!--confirmed by the Ultimania--> While collecting five of the six near-perfected replicas left behind by Vexen, to house the time traveling hearts of [[Ansem, Seeker of Darkness|Ansem]], [[Xemnas]], [[Young Xehanort]], [[Vanitas]], [[Dark Riku]], Saix additionally found Vexen's records on the replica project and the forgotten prototype [[Xion|No. i]], sparking his memory of Xion; adding onto his atonement. {{Storylink|Kingdom Hearts III Re Mind}}

When Xehanort's attempt to make Sora his final vessel ends in failure due to Lea's intervention, Saïx attacks his former friend. As their weapons collide, his identity is revealed to Lea, shocking him. Wistfully recalling his former friendship with Isa, Lea knocks Saïx away to regroup with Riku and King Mickey. After Donald and Goofy arrive, the real Organization XIII retreat to await the time to properly forge the [[χ-blade]].

After the replicas proved unable to hold time traveling hearts indefinitely, Saïx retreats to the [[Keyblade Graveyard]] with Master Xehanort and Xigbar. After confirming that [[Terra-Xehanort]], Marluxia, Luxord and Larxene are the only ones in the present, Saïx "suggests" using Xion to take the thirteenth slot, deeming Vexen and [[Demyx]] reserves. He leaves to get Vexen, while Xigbar heads to turn Demyx back into a Nobody.{{storylink|Kingdom Hearts III Re Mind}}

Saïx visits [[Even]] in Radiant Garden's central square and offers him the chance to atone for his past actions as [[Vexen]] through the [[replica]]s. [[Even]] accepts and returns to his Nobody form.{{storylink|Secret Report 7}} Together, Saïx and Vexen fool Master Xehanort into thinking they returned to fill the ranks of the new Organization. {{Storylink|Secret Report 8}} Later meeting at the Keyblade Graveyard, Vexen updates Saïx on his progress with perfecting the replicas; very soon they will be able to become real people once they're given hearts.

[[File:Opposing Goals 01 KHIII.png|thumb|right|200px|At the Clock Tower, Saïx and Lea discuss their past with Subject X.]]

In Twilight Town, Saïx meets with Lea on the {{c|Clock Tower|tt}}. The two recount their original intent on rescuing [[Subject X]] before joining the Organization. When Saïx says that it is useless in rescuing their lost friends, Lea counters that he will find a way to find them and Isa.

In the Keyblade Graveyard, Lea and Kairi pair up to fight Saïx and Xion. Sora soon joins them but Saïx overpowers them. As Saïx rushes to finish Sora and Kairi, Lea defends them while telling Saïx to stop but is pushed back. Then Xemnas appears and condemns Lea for becoming a traitor when he used to be the one trusted to deal with them. Saïx watches silently as Xemnas attacks and injures Lea as well as the hooded figure, revealed to be Xion before Roxas appears and comes to their rescue.

Saïx wears a basic Organization black coat, along with the usual black gloves and boots. He has long blue hair vaguely reminiscent of Vexen's in style and length, though Saïx's is a bit wilder at the top. Most of his hair is tucked into his cloak, though a portion is not and falls over the back. As a vessel for Xehanort's heart, Saïx shares his pointed ears and amber eyes, as does his fellow vessel Xigbar. Saïx also wears stud earrings like Xaldin's. The X-shaped scar on Saïx's face is his most distinctive trait, with the vertex of this "X" lying between his eyes and extending from halfway up his forehead to just under his eyes. When Saïx enters his "Berserk" state, his eyes turn completely yellow, his scar becomes more jagged and a bit larger, and his hair becomes spiky and unruly.  

A slightly-modified copy of Saïx's body model is used for [[Young Xehanort]]'s in ''Kingdom Hearts Birth by Sleep'', though it is likely that this is simply due to data recycling rather than any deeper significance.

Along with Xemnas, Saïx appears to be one of the most "Nobody-like" of the Organization. Despite claiming to remember what possessing a heart was like, he behaves mostly as a cold, emotionless, and efficient operative, even in the direst of situations. He is very aware of how emotions are unreal to them, unlike other members who imitate their emotions. However, in ''Kingdom Hearts 358/2 Days'', it seems he values his friendship with Axel from their time as humans, indicating that he believes that Nobodies cannot even try to genuinely show emotion or form a real friendship without having had one with another beforehand, thus having memories to fall back on. According to Axel, the friendship between them weakened due to how Saïx changed too much after becoming a Nobody, leading to Axel ignoring him for Roxas and Xion.{{storylink|Day 118: You Changed, Not Me}} Thus, Saïx has a colder demeanor towards Axel in ''Kingdom Hearts II''.

In '' Kingdom Hearts III'', Saix is shown to draw upon the limited moonlight at dusk. He also has access to a secondary "Berserk" guage, allowing him to create four additional claymores to attack with; he can use them as shields or a supply of makeshift projectiles.
