Xion

Xion is the fourteenth member of Organization XIII and first appears in the game Kingdom Hearts 358/2 Days, in which she could be viewed as both a main protagonist and antagonist. She is not actually a Nobody, and not even a true member of the Organization. Instead, she's an imperfect Replica of Sora created from his leaked memories as a fail-safe in case he or Roxas proved to be useless to Organization XIII's plans. But as she becomes sentient over time, Xemnas decides to use her to ensure Sora never awakens and dispose of Roxas. While this enables her to use the Keyblade, Xion's existence also slows Sora's progression of regaining his memories to fully awaken while in his pod, something which Naminé, DiZ, and Riku recognize.

Xion's name contains the Japanese words for "tide" (潮), fitting the oceanic naming theme of Kairi and Naminé, and Aster tataricus (紫苑). According to Japanese floriography, Aster tataricus is used to mean "I won't forget you" or "remembrance." Among the other Secret Reports obtained at the end of the game, it is revealed that she is experiment "No.i" of the Replica Program, and that she was bestowed a proper name, Xion, because living things need names to give meaning to their existence, and being a member of the Organization.

Kingdom Hearts 358/2 Days


Reports on this figure have existed for some time now. It was assumed this was the man who defeated Xion, but the truth of the matter remains unclear.


 * Xion: First Form

''Xion, transformed. Sora's memories from each world have multiplied her powers.'' ''Her barrier restores HP. Stop it by striking with your weapon before she can raise it. She'll counter if you block her sword combo, so dodge roll out of the way instead.'' She will always spread her wings to signal her Sonic Blade charge.


 * Xion: Second Form

''Xion, transformed. Sora's memories from each world have multiplied her powers.'' ''Her Ragnarok attack fires homing lasers that cannot be blocked—dodge them instead. However, play too hard to get and she'll fire repeatedly.'' Strike with your weapon if you see her trying to raise a barrier to prevent it from healing her.


 * Xion: Third Form

''Xion, transformed. Sora's memories from each world have multiplied her powers.'' ''Beware her Ars Arcanum attack, a fierce flurry of blows from her four arms. Most of her attacks cannot be blocked, so dodge roll out of the way, then counter.'' Strike with your weapon if you see her trying to raise a barrier to prevent it from healing her.


 * Xion: Final Form

''Xion's ultimate transformation. Sora's memories from each world have multiplied her powers.'' ''This form packs a new arsenal of moves, including a powerful Final Limit once her HP dwindles. Glide up to her side and take shelter before it connects.''

Kingdom Hearts 358/2 Days
A week after Roxas joins Organization XIII, Xemnas introduces Xion to the other members. After looking at the other members, she smiles up at Roxas, puzzling him. As Roxas departs for his first training mission, he spots Xion shyly watching him nearby, and Saïx formally introduces her to Axel and Roxas.

When Axel is sent to Castle Oblivion, Xemnas entrusts Roxas to look after Xion, who quickly bonds with him. She reveals her ability to wield the Keyblade to him, and looks after him when he falls into a coma for several weeks in conjunction to Sora being put to sleep to regain his memories. After discovering that Sora and Riku had slain all of the Organization members (except Axel) that were in Castle Oblivion at the time, Roxas, Axel, and Xion all begin spending more time together as per Roxas's suggestion and become fast friends.



However, a series of events begin to split the trio apart: While DiZ and Naminé oversee the restoration of the sleeping Sora's memories (moving him from Castle Oblivion to Twilight Town), Roxas begins to experience the process for himself, and begins to ponder over how he is able to wield the Keyblade and doubt the Organization's motives; Axel is reprimanded by their superiors for placing his friendship with Roxas and Xion before the Organization's goals; and Xion is thrown into disarray after a confrontation with Riku, who questions who she is and why she wields the Keyblade, becoming torn between staying with her friends and leaving the Organization to merge with her true self as Riku suggests. Xion travels with him before being captured by Axel and brought back into the Organization. However Naminé's attempts to restore Sora's memories are soon faltered when Xion starts getting them more, causing Roxas to weaken while she becomes stronger s Xemnas intended. Eventually, after being tricked into fighting Roxas to the death by Saïx, Xion decides to take Riku's advice and leaves the Organization.



After her departure, Xion comes into contact with Naminé at Twilight Town's Old Mansion, questioning her own existence and the fate that will soon befall Roxas. Around this time, she discovers her true nature that the form she normally assumes is from memories Sora holds of Kairi. Naminé also reveals in their meeting that with Xion that as she was constructed from Sora's memories, she will be forgotten by everyone when she relinquishes them with Naminé herself can't stop it. Seeing that she and Roxas cannot coexist, placing him in danger, Xion accepts her fate and cease to be. However, Xion learns that Axel tracked her down and she confronts him, refusing to let her go through with sacrficing herself as he accomplishes his mission with full force, leading to a heated battle. Having defeated Xion, Axel brings her back to The World That Never Was, but soon faints from fatigue. Xemnas then steps out from the shadows and carries the unconscious Xion away to reprogram her into the devices he had installed across the worlds.

Soon afterwards, Xion confronts Roxas at the Twilight Town train station, and after revealing true form to him, assumes a Nobody-like state and using the devices to enhance her as she attacks him in order to absorb Roxas and achieve her purpose to become the "real" Sora and prevent the real Sora from ever awakening. But in reality, Xion was forcing Roxas to destroy her so only he can exist and Xemnas's plan to delay Sora's awakening would be stopped. Returning to her original form, Xion begins to crystalize as a confused Roxas pleas her to not go as he begins losing his memories of her. Xion tells him that she has no regrets for meeting him or Axel, pleading with him to free Kingdom Hearts from Xemnas before dying peacefully in his arms. Saddened, Roxas holds Xion's essence and degenerating crystallized body until she is completely gone, leaving behind a sole seashell, in addition to inadvertently giving him her Keyblade which becomes Oblivion. Though the process begins, with Roxas starting to forget Xion completely, Xenmas and Saïx were immune to the effects while Riku only breifly remembers her upon holding Oblivion during his fight with the NeoShadows. After Roxas knocked out by Riku when he transforms into Xehanort's Heartless, Xion's voice is heard as she assures Roxas that she lives on within both him and Sora, telling him the memories of their time will remain even if forgotten.

Kingdom Hearts Birth by Sleep
She appears in Kingdom Hearts Birth by Sleep's secret video, Reconnect. Kingdom Hearts, in Twilight Town eating Sea-Salt Ice Cream with Roxas, and Axel atop the clock tower. Both Roxas and Xion said Sora's name while watching the sunset.

Appearance
Xion's Organization coat is similar to the one Roxas wears, only a bit shorter with slightly pointed shoulders and closer-fitting sleeves. She also wears the more feminine, heeled boots that Larxene wears and the basic black gloves. She resembling a hooded doll, Xion resembles Sora when she takes her hood off.

As Sora's memories are the basis and component of her being, Xion's physical appearance eventually changes depending on who is viewing her and who they have connections with. The fact she mostly assumes in the eyes of Roxas, and later Axel and Riku, strongly resembles Kairi in her appearance from the original Kingdom Hearts only that her hair is black and parted on the left side of her head rather than the right as it was on Kairi.

As a result of her being crafted from Sora's memories, Xion's appearance is somewhat unstable and she transforms into both Sora and Riku in their original Kingdom Hearts appearances. Her appearance is also slightly different depending on who is looking at her, which is most noticeable when Xigbar sees her as Ventus. She briefly assumed Riku's Kingdom Hearts appearance as she learns of her true nature and later that of Ventus during her fight with Xigbar.

During Roxas's battle with Xion, she dons Sora-style armor which changes a number of time throughout the fight. Her basic form is a bizzarely-shaped suit that is predominantly silver and black, with some dull red armor near her waist, gold on her boots, and orange armored gloves. Xion's helmet sports two black spikes that jut out horizontally on either side and a large, red Nobody symbol on the faceplate, part of which forms something of a horn on the top of the helmet.

In her first fightable form, Xion has large, skeletal, colorful wings and a huge, orange and red, intricately-shaped sword. In her second form, Xion loses her wings and grows to be about twice the size of Roxas, summoning a large, scythe-like weapon vaguely resembling the Decisive Pumpkin Keyblade or a Chimaera arm as a weapon. For the third section of the battle, Xion transforms into a figure with four huge arms, decorated with elegant, gold, purple and red designs. She also has large blades instead of hands, resembling Kurt Zisa's own arms. Her main body is also slightly larger than normal during this part of the battle. In her final transformation, Xion grows to titanic size, about the same height as the Train Station tower. Her armor is now embroidered with numerous spikes and ribbons. She also gains two Keyblade-like, pink and silver weapons with the teeth in the shape of the Nobody symbol as well as Sora's signature crown's spot is replaced with a Nobody symbol.

Personality
First arriving at Organization XIII, Xion is a shy, secluded individual. When going on a mission with Roxas, Xion begins to open up to him, and later Axel. She does seem to express emotions due to her nature of existence, and is always happy to be with her friends. However, she is somewhat emotionally fragile, becoming deeply enraged with the right provocation. After finding out the origins of her existence, she also becomes deeply confused and lost.

Xion seems to take an interest in seashells. While Roxas was in a coma when Sora was put to sleep, Xion put a seashell on his bedside table every day he was asleep. In her nightmare on Destiny Islands, Roxas is in the dream and picks up a shell while whispering her name. After Xion was absorbed into Roxas, all that was left of her was a single seashell. This is likely a reference to how Kairi also had a liking for seashells.

Fighting Style
As an indirect Replica of Sora through Roxas, Xion's fighting style as a playable character is very similar to his. After absorbing many of Sora's memories using the Organization XIII Devices, Xion is able to replicate Sora's Limits from the first Kingdom Hearts. However, Xion's movement is quite similar to Limit Form's, jumping back and stepping forward between attacks and slashing through the enemy in the finisher. Like Roxas, she thrusts with one hand and her finisher resembles the Vortex ability. Xion's Limit Break, Event Horizon, involves covering her Keyblade in an aura of Light and performing a devastating combo. Xion can also call down elegantly shaped pillars of light to attack nearby and far away enemies. Before Xion obtains the Keyblade herself, she is limited to simply shooting magic out of her hand, none of which is Light-based.

Once she obtains her Keyblade, Xion is very good at handling it, being able to fight with it using her right or left hand. Her boss battle depicts her using many powerful melee attacks she seemed to have inherited from Sora. She also uses light much more often during her boss fight, such as creating spiraling circles of Light that suck in the player, leaving them vulnerable to one of Xion's aforementioned physical attacks. She can also use a Light spell similar to Ragnarok, and can envelope her weapon in Light to make her other attacks even more powerful.

Weapon
As Roxas's Replica, Xion can wield the Keyblade Kingdom Key. She wields her weapon fairly skillfully, being able to disarm Axel. Because Xion and Roxas are both part of Sora, they can both wield his Keyblade, even at the same time. Xion and Roxas can share keychains with each other, allowing them to use the same Keyblades and limit break in multiplayer mode. After she fades back to Sora, Roxas gains her Keyblade is uses it with his own, turning Xion's Keyblade into Oblivion.

It is notable that, when Xion runs with her keyblade, she grasps it with two hands instead of slinging it over her shoulder. This is similar if not identical to how Sora runs with his keyblade in Kingdom Hearts II.

Playing as Xion
In Kingdom Hearts 358/2 Days, Xion fights in the exact same manner as Roxas, acting as nothing more than a gameplay carbon copy. Like Roxas, she also has low, but even stats, which make her just as versatile as Roxas, able to specialize in any specific area. Via the Gear System, Xion can be customized along with all other playable characters, using Keyblades to augment any specific combat area the player wishes. Xion's Limit Break, Event Horizon, is the exact same Limit Break that Roxas uses. She rapidly attacks around the field while her Keyblade is enveloped in light, slashing away at enemies with great speed and strength. During the Final Limit, Xion summons four thin pillars of light that quickly move in straight paths to the ends of the field, dealing heavy damage to any enemies in their path. Unlike Roxas however, Xion is unable to Dual-Wield her Keyblades by using the Zero Gear and three ability units; her weapon will just revert to a Kingdom Key+ with this panel combination.

Trivia

 * Xion's name was coined by Tomoco Kanemaki, one of Kingdom Hearts 358/2 Days's scenario writers. Tetsuya Nomura took a liking to it and notes that it has many meanings.
 * Xion, Zexion, and Lexaeus are the only Organization members who never physically met Sora, but Xion is the only one Sora never knew of. Sora can be considered to have learned about Zexion and Lexaeus through Jiminy's Journal entries in Kingdom Hearts II.
 * Xion and Larxene are the first female characters that are playable in the Kingdom Hearts series.
 * Xion is one of four Organization members to have their own battle theme. The other three members are Roxas, Xemnas, and Marluxia.
 * After Roxas joined with Sora, information about the other Organization members will be added to Jiminy's Journal except Xion's. This is because Xion hadn't been thought of yet. Another reason is because all of the memories of her had been completely erased, as seen in the cutscene before battling Riku in 358/2 Days.
