{{Q|True, we don't have hearts, but we remember what it was like. That's what makes us special.|Saïx to Donald}}
'''Saïx''', the {{nihongo|''Luna Diviner''|月に舞う魔人|Tsuki ni Mau Majin|lit. ''Demoniac Dancing in the Moon''}}, is the [[Nobody]] of [[Isa]], Rank VII within the original [[Organization XIII]] and a member of the [[real Organization XIII]]. He derives power from the moon and uses this power to enter a berserk rage where he mercilessly attacks opponents with his massive claymore. He commands the [[Berserker]] Nobodies.

In the original Organization, Saïx serves as the second-in-command to [[Xemnas]], and is 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]].

==Story==
===Before ''Kingdom Hearts 358/2 Days''===
Saïx joins the Organization with [[Axel]], believing that [[Xemnas]] would know what happened to their friend [[Subject X]]. To this end, Saïx works to get as close to Xemnas as possible while Axel secretly assists him to further their goal.

===''Kingdom Hearts 358/2 Days''===
{{Q|Which would you rather suffer the loss of? Some make-believe friendship? Or a real one?|Saïx to Axel}}
Saïx assigns missions to the other Organization members. Along with [[Xemnas]], [[Xigbar]] and [[Vexen]], he also oversees the [[Replica Program]]. When [[Roxas]] is brought into the Organization as its thirteenth member, Saïx suggests he keep a diary.{{storylink|Day 7: Entry 1}} 

After Sora defeats [[Ansem, Seeker of Darkness]], Saïx sends [[Marluxia]], [[Larxene]], [[Vexen]], [[Lexaeus]], [[Zexion]], and [[Axel]] to [[Castle Oblivion]], intending for Axel to eliminate the members who planned to betray the Organization.

[[File:Axel and Saïx 01 KHD.png|thumb|left|Saïx asks whether Axel prefers his friendship with Roxas and Xion to their own.]]
Over time, Roxas and Xion's friendship with Axel creates tension between Saïx and Axel. Saïx grows frustrated with Xion's declining performance as she struggles to wield the [[Keyblade]], as well as with Axel's attachment to her.

With Roxas getting weaker from Xion sapping his strength, Saïx plans for them to fight to the death, as the Organization only needs one [[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.

When Roxas leaves the Organization, Saïx attempts to stop him, but is defeated.

After Xion's demise, Xemnas orders Saïx to retrieve Roxas.

===''Kingdom Hearts II''===
[[File:Saïx's Puzzling Words 01 KHII.png|thumb|Saïx leaves after successfully confusing and frustrating Sora.]]
Saïx appears with the rest of the surviving Organization members to taunt Sora at [[Hollow Bastion]]. When the Organization discusses their plans for Sora, Saïx expresses his doubts on Sora's usefulness and states that those who have lost their "true purpose" will inevitably destroy themselves.

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

Saïx confronts Sora upon Sora's second visit to [[Twilight Town]], leaving him confused and frustrated. Saïx warns Sora that Axel has betrayed the Organization and is attempting to turn Sora into a [[Heartless]].

[[File:Xemnas' Thoughts 03 KHII.png|thumb|left|Saïx explains how the Organization intends to use the Heartless.]]
During the [[Battle of the 1000 Heartless]], Saïx appears while Axel is telling Sora about the Organization's plans, forcing Axel to flee. Sora pleads with Saïx to take him to Kairi. Saïx refuses, and tells 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 the Nobodies overwhelm Maleficent, Saïx summons more Heartless and departs through a [[corridor of darkness]].

[[File:Kairi and Naminé 01 KHII.png|thumb|Saïx tells Kairi that she will fuel Sora's anger.]]
In the [[Castle That Never Was]], Saïx watches over Kairi in her cell, telling her that she is "the fire that feeds Sora's anger". When [[Naminé]] rescues Kairi through a corridor of darkness, Saïx appears to prevent their escape. Riku, still cloaked and in the form of [[Ansem, Seeker of Darkness]], comes to Kairi's aid and attacks Saïx, who retreats through a corridor of darkness.

Saïx appears to Sora in the Hall of Empty Melodies. He tells Sora that Kairi no longer needs him as a "friend from the darkness" is with her. Saïx summons more Heartless for Sora to destroy before leaving. Saïx then appears to Xemnas, who is watching Kingdom Hearts come closer to completion, and asks if he can end the "charade," to which Xemnas agrees.

[[File:The Luna Diviner Saïx 02 KHII.png|thumb|left|Saïx summons his Claymore and attacks Sora and his friends.]]
Elsewhere in the castle, after [[Luxord]]'s defeat, Saïx awaits Sora, Donald, Goofy, Riku, and Kairi in the [[Addled Impasse]]. He calls Sora by Roxas's name and declares that the two of them will share the same fate before creating a shockwave that pushes Kairi and Riku back. Saïx confronts Sora, Donald, and Goofy, but is defeated. In his last moments, he reaches for Kingdom Hearts, asking it where his own [[heart]] is before fading away.

===''Kingdom Hearts 3D: Dream Drop Distance''===
[[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 agrees to rejoin the group and becomes 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 in order to house the time traveling hearts of [[Ansem, Seeker of Darkness|Ansem]], [[Xemnas]], [[Young Xehanort]], [[Vanitas]], and [[Dark Riku]], Saix finds Vexen's records on the replica project and the forgotten prototype [[Xion|No. i]], sparking his memory of Xion. {{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 [[Lea]], revealing his identity. After Donald and Goofy arrive, the real Organization XIII retreat to await the time to properly forge the [[χ-blade]].

===''Kingdom Hearts III''===
{{Q|Got it memorized?|Saïx to Lea}}
[[File:The Plan 02 KHIIIRM.png|thumb|left|200px|Saïx and Xigbar discuss with Master Xehanort how they'll achieve a total count of thirteen vessels.]]
After the replicas proved unable to hold time traveling hearts indefinitely, Saïx retreats to the [[Keyblade Graveyard]] with Master Xehanort and Xigbar. After confirming the status of the other members, Saïx suggests using Xion to take the thirteenth slot, deeming Vexen and [[Demyx]] "backups". In reality, Saïx had planned to have them act in his stead to undermine the organization's efforts and help Xion and Roxas, something he couldn't do being a main member; by suggesting Demyx and Vexen be backups, Saïx gave them the freedom to do so. He then leaves to recruit Vexen. {{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 work secretly to provide replicas for "those who truly deserve them". {{Storylink|Secret Report 8}} Later meeting at the Keyblade Graveyard, Vexen updates Saïx on his progress with perfecting the replicas, telling him 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 Clock Tower. The two recount their original intent of rescuing [[Subject X]] before joining the Organization. Saïx tells Lea that Roxas is gone, just like Subject X, to which Lea declares that he will find a way to save all of his friends, including Saïx.

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 towards Sora and Kairi, Lea steps in to defend them but is pushed back. Xemnas appears and condemns Lea for his traitorous actions. Saïx watches silently as Xemnas attacks and injures Lea as well as Xion before Roxas appears and comes to their rescue.

[[File:You Admit It 02 KHIII.png|thumb|left|200px|Saïx reconciles with Lea and fades away in his arms.]]
Xemnas proceeds to kidnap Kairi and leaves the group to fight the berserk Saïx. Xion and Roxas aid Sora in battling Saïx as Lea is too injured to fight. When the battle concludes, Lea rushes over to Saïx. Saïx admits his feelings of jealousy towards Lea's friendships with Roxas and Xion and reconciles with Lea before fading away.

==Other appearances==
===''Kingdom Hearts Union χ[Cross]''===
Saïx appears as an enemy in the July 2018 {{khux|NEW XIII Event}}.

===''Super Smash Bros. Ultimate''===
In ''{{ssb|Super Smash Bros. Ultimate}}'', Saïx appears in the 5 o'clock Stations in the [[Dive to the Heart]] sections of the {{ssb|Hollow Bastion}} stage.

==Design==
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. 

Saïx's transformation under the moon's power is a possible reference to several things, including the ancient belief that the moon caused madness, hence the term "lunatic"; the modern belief that the phases of the moon can affect a person's mood; the legend of the werewolf, humans who became savage beasts under the influence of a full moon; as well as the {{w|Berserker|berserker warriors}} of the Norse, who wore clothes made from bearskins as they went into battle in an insane fury and are the source of the modern term "berserk."

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.

==Personality==
{{Q|If I had a heart, this would be where I die of laughter.|Saïx}} 
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''.

Saïx would later admit that his cold treatment of Axel was due to him being jealous of Axel's friendship with Roxas and Xion after Axel seemingly forgot about him and their goal of finding the girl; though Saïx would later admit that he knew better and that his old friend would never forget nor abandon him.

The only thing Saïx seems to "care" about is acquiring a heart and, by extension, Kingdom Hearts. More than any other member of the Organization, Saïx is portrayed the most dedicated to their goal, repeatedly stating his desire to "truly, finally exist". Even his last words were to Kingdom Hearts, sadly asking for his heart. Though this doesn't make him blind to Xemnas's plans to use Kingdom Hearts for more power, as he had originally plotted with Axel to overthrow Xemnas to regain their hearts. Saïx can also be quite cruel, claiming to know very well how to injure a heart. He had a keen insight into manipulating others, such as when he toyed with Sora's emotions by having him beg to see Kairi, only to refuse his request. He also sent the "useless" members to Castle Oblivion under the guise of Xemnas's orders to clear the way for his and Axel's plans, moving up the ranks while eliminating any competition or rebellion.

However, his usual calm exterior belies a more savage nature. In his final confrontation with Sora under the heart-shaped moon of Kingdom Hearts, he becomes a berserk force of destruction. Unlike his calm and reserved manner, in battle, he roars, shouts, and attacks relentlessly with no sense of self-control and portrays a psychotic behavior under the influence of Kingdom Hearts.

''Kingdom Hearts III'' has Saïx show a more sympathetic and remorseful side. Seeking redemption and forgiveness for his treatment of Roxas and Xion and a desire to rekindle his friendship with Axel, Saïx infiltrates the real Organization and ensures the guardians of light are given access to the replicas to save the two. He eventually becomes friends with Roxas and Xion after he returned to his human self. Saix is also good at being subtle, trying to jog Xion's memories by using the names of her friends [[Axel]] and [[Roxas]] without drawing Xemnas's suspicion.

==Abilities==
[[File:Saïx (Berserk) KHIII.png|thumb|200px|Saïx in his berserk state.]]
{{Main|Game:Saïx}}
Saïx is a powerful member of Organization XIII and a capable fighter. Although he appears calm and collected throughout when speaking, in battle he becomes a wild, dangerous opponent. He uses brute strength and his large Claymore to attack, but his true danger is his "Berserk" form, which uses the power of the moon. As proof of his power, in ''Kingdom Hearts III'', Saïx was capable of overpowering Sora and Kairi while in his Berserk form and would have easily finished both, including Lea and the renegade Xion if Roxas hadn't come to aid them in the confrontation. A "Berserk" gauge at the top of the screen measures how close he is to becoming berserk. When it fills, Saïx's Lunatic Claymore shifts shape and produces a white aura that serves as extra blades. Saïx himself grows bestial, with glowing eyes, manic hair, and bared fangs. Saïx's strength and speed increase greatly, and he will rapidly slam his Claymore into the ground, producing shockwaves. When he swings or throws the Claymore, it will leave a wake of blue flames.

However, Sora can pick up any of the Claymores that Saïx releases, allowing him to use Reaction Commands that will knock Saïx out of his berserk state, as well as inflicting significant damage. When knocked out of his berserk state, Saïx will spend most of his time with his arms stretched towards the moon, absorbing its power.

The Nobodies under his command, the Berserkers, follow his attack style, using brute strength and a large weapon, but share the same weakness as Saïx.

In ''Kingdom Hearts 358/2 Days'', Saïx's Limit Break is also called {{c|Berserk|Limit Break}}.  During Berserk, Saïx enters a berserk stage; he rushes across the field and causes shockwaves. This intensifies during the Final Limit.

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.

===Weapon===
Saïx wields a massive blade known as a '''{{c|Claymore|weapon}}'''. His signature Claymore is known as '''[[Lunatic]]'''. Despite many dissimilarities to real claymores, Saïx does use a very large, two-handed bladed weapon. His Claymore is decorated with many additives that resemble the Nobody logo, in blues and yellows. When in normal form, Saïx attacks with powerful slashes and combos with the bladed edges.

Although it seems to be a completely different weapon, the Cursed Hammer of the Berserker Nobodies is used in much the same way and even has the same Reaction Command.

The names of Saïx's various claymores are all references to astronomy or astrology (especially the moon), with the exceptions of [[Dichotomy]]'s Japanese name, Crocea Mors (Latin for "yellow death"), which is the purported name of Julius Caesar's sword; and Just Desserts, his joke weapon.
