Demyx - Kingdom Hearts

DEMYX

“The Melodious Nocturne”

Demyx is Number IX of the original Organization XIII and later serves as a reserve member of the real Organization XIII. He is a Nobody who uses music and a large sitar to control water. Although he presents himself as lazy, cowardly, and incompetent, Demyx is considerably more dangerous than his behavior suggests.

GENERAL INFORMATION

Name: Demyx Japanese Name: デミックス — Demikkusu Original Human Name: Unknown Title: The Melodious Nocturne Organization Number: IX Affiliation: Organization XIII; reserve member of the real Organization XIII Nature: Originally a Nobody; later returned after his destruction Gender: Male Age: Unknown; appears to be a young adult Birthday: Unknown Homeworld: Unknown Element: Water Weapon: Sitar Signature Sitar: Arpeggio Associated Nobodies: Dancer Nobodies Limit Break: Wave Gigs English Voice Actor: Ryan O’Donohue Japanese Voice Actor: Kenichi Suzumura First Appearance: Kingdom Hearts II Current Status: Alive or otherwise active; exact whereabouts unknown

Demyx’s number represents the order in which he joined Organization XIII, not his strength or authority.

APPEARANCE

Demyx is a lean young man with sea-green eyes and brown-to-dirty-blond hair that becomes lighter toward the ends. His hair resembles a dramatic mullet: the sides are cut extremely short, while the top and back are longer, spiked, and uneven. Several loose strands fall across his face.

Like the other members of Organization XIII, he wears a long black coat with silver fasteners, black gloves, dark trousers, and knee-length black boots. His coat has pronounced pointed shoulders and relatively fitted sleeves.

In Kingdom Hearts III, Demyx’s eyes appear golden, suggesting that he has been exposed to Xehanort’s influence while serving as a reserve member of the real Organization XIII.

PERSONALITY

Demyx is casual, playful, lazy, talkative, and openly reluctant to work. He dislikes physical exertion, avoids serious missions whenever possible, and repeatedly insists that he is not suited for combat. He prefers reconnaissance assignments because they allow him to observe events without becoming directly involved.

He frequently complains, exaggerates his fear, tries to pass his responsibilities to other members, and uses humor to escape uncomfortable situations. In Kingdom Hearts 358/2 Days, he even manipulates Roxas into completing much of their mission while Demyx relaxes.

Despite his apparent cowardice, Demyx is not stupid. He is observant, socially aware, sarcastic, and capable of recognizing opportunities. His harmless behavior may partly function as a defense mechanism: if everyone believes he is useless, they are less likely to view him as a threat.

Demyx possesses a strong desire to be noticed and included. He dislikes being treated as disposable and becomes genuinely offended when he is benched by the real Organization XIII. Vexen later exploits this frustration by promising him a chance to have his own moment, which Demyx calls “Demyx Time.”

His relationship with emotions is deliberately ambiguous. During Kingdom Hearts II, he insists that Nobodies do have hearts. Sora dismisses him, causing Demyx’s cheerful demeanor to disappear immediately. Later games confirm that Nobodies are capable of developing new hearts, meaning Demyx’s apparent emotions may have been more genuine than the Organization claimed.

Demyx is not entirely kind or innocent. He participates in teasing Xion, expresses satisfaction over Larxene’s disappearance, and can become cold and aggressive when insulted. However, he also shows more concern and hesitation than many other Organization members and ultimately helps undermine Xehanort’s plans.

SERIOUS SIDE

Demyx’s most important personality shift occurs before his final battle with Sora.

After Sora, Donald, and Goofy mock him and describe him as weak, Demyx warns them not to judge anyone by appearances. When Sora claims that Nobodies do not possess hearts, Demyx immediately drops his nervous, playful behavior.

His voice becomes calm and hostile, and he responds:

“Silence, traitor.”

This moment demonstrates that his cowardly personality does not represent the full extent of his character. When genuinely angered or forced into battle, Demyx can become focused, commanding, and frighteningly powerful.

POWERS AND ABILITIES

Demyx controls water through music. Rather than fighting directly, he usually plays his sitar and allows the water under his command to attack for him.

His abilities include:

• Creating human-shaped water clones known as water forms. • Summoning water in the shape of musical notes. • Producing powerful geysers and pillars of water. • Launching exploding spheres of water. • Surrounding himself with water to increase the range of his physical attacks. • Forcing enemies to destroy his water forms within strict time limits. • Using his sitar’s bladed headstock as a physical weapon. • Traveling between worlds through Corridors of Darkness. • Commanding Dancer Nobodies.

His signature command is:

“Dance, water, dance!”

Although official reports describe Demyx as a poor fighter, his battles prove that he is extremely dangerous when forced to use his full abilities. His apparent weakness comes primarily from his lack of motivation and his preference for letting summoned water fight in his place.

WEAPON: ARPEGGIO

Demyx’s signature weapon is an enormous blue sitar named Arpeggio. Its body resembles the Nobody emblem and functions as both a musical instrument and a bladed melee weapon.

Demyx plays its strings to create and command water. When forced into close combat, he swings it like a guitar, using spinning and theatrical movements similar to a rock musician performing onstage.

LIMIT BREAK: WAVE GIGS

In Kingdom Hearts 358/2 Days, Demyx’s Limit Break is called Wave Gigs. He repeatedly plays his sitar to summon water pillars around his enemies. During his Final Limit, he also creates exploding balls of water.

COMPLETE CANON HISTORY

BEFORE ORGANIZATION XIII

Almost nothing is known about Demyx’s original life.

His original human identity, name, homeworld, family, and reason for losing his heart have never been revealed. After becoming a Nobody, he was discovered and recruited into Organization XIII as its ninth member.

His strong will allowed his body and soul to continue existing as a Nobody after his heart became a Heartless.

KINGDOM HEARTS 358/2 DAYS

Demyx is already an established member of Organization XIII when Roxas and Xion join.

He spends much of his free time sitting in the Grey Area of the Castle That Never Was and playing his sitar. He openly admits that he is not suited for combat and would rather perform reconnaissance.

Demyx accompanies Roxas on several missions, including assignments in Olympus Coliseum and Halloween Town. During these missions, he regularly attempts to avoid work. At Olympus Coliseum, he allows Roxas to undergo Phil’s training while pretending that he will handle the Heartless outside.

He is present when Xion is introduced to the Organization and occasionally joins Xigbar in teasing her. However, he is visibly shocked when Xemnas eventually reveals that Xion is part of the Replica Program.

Demyx is also the first member to tell Roxas about the deaths of the Organization members sent to Castle Oblivion. He appears particularly pleased that Larxene is gone because he strongly dislikes her.

KINGDOM HEARTS II — OLYMPUS COLISEUM

Demyx appears with the surviving members of Organization XIII at Hollow Bastion. When the Organization discusses allowing Sora to continue defeating Heartless, Xigbar jokingly interprets Demyx’s suggestion as an offer to handle the assignment himself.

Demyx is consequently sent to Olympus Coliseum to investigate Sora and awaken Roxas’s “true disposition” inside him.

He briefly approaches Hades but runs away before making any meaningful agreement. Demyx later steals the Olympus Stone, an object capable of protecting its holder from the Underworld’s curse.

When Sora confronts him, Demyx reads his mission instructions from cue cards. He addresses Sora as Roxas and attempts to provoke the part of Roxas believed to exist inside him.

Demyx summons numerous water clones and forces Sora to destroy them within a limited amount of time. After losing, he abandons the Olympus Stone and escapes while pleading with Roxas to return to the Organization.

KINGDOM HEARTS II — HOLLOW BASTION

Demyx returns during the Battle of the 1,000 Heartless and attempts to prevent Sora from advancing.

Sora, Donald, and Goofy underestimate him because of their previous encounter. Demyx warns them that they should not judge him by his appearance. When Sora denies that Nobodies possess hearts, Demyx drops his friendly façade and attacks with his full power.

Despite his water manipulation and large army of water forms, Demyx is defeated. He screams as his body dissolves into darkness, seemingly ending his existence.

RETURN AND THE REAL ORGANIZATION XIII

Because both Demyx’s Nobody and corresponding Heartless were eventually destroyed, his original existence could be restored. The exact circumstances surrounding his return are not shown.

Demyx is later recruited as a reserve member of Master Xehanort’s real Organization XIII. However, he is not given one of the final thirteen active positions and becomes deeply annoyed about being benched.

KINGDOM HEARTS III

Demyx meets Luxord, Marluxia, and Larxene at the Keyblade Graveyard. Xemnas tells the four of them that an ancient Keyblade legacy is sleeping within them.

This establishes that Demyx possesses an unexplained connection to the ancient Keyblade era. However, the game does not reveal his original identity or confirm that he personally wielded a Keyblade.

Vexen later approaches Demyx in Radiant Garden and asks him to help sabotage the real Organization XIII from within. The operation is secretly connected to Saïx’s plan to restore Roxas, Xion, and Naminé.

Demyx initially points out that he and Vexen were never friends. Vexen explains that their lack of a known relationship makes Demyx the ideal secret accomplice.

Demyx agrees, partly because he wants an opportunity to prove that he matters.

He subsequently transports Ansem the Wise and one of Vexen’s replica bodies to Ienzo in Radiant Garden. The replica becomes essential to restoring Roxas.

KINGDOM HEARTS III RE MIND

Following Dark Riku’s defeat at the Keyblade Graveyard, Demyx arrives to retrieve the now-empty replica vessel. He shows Riku the Gummiphone Ienzo gave him as proof that he is cooperating with Radiant Garden.

Demyx takes the replica back so it can be used to restore Naminé.

This is his last confirmed chronological action. He does not participate in the final confrontation with Master Xehanort and is not shown being destroyed afterward. His exact current location remains unknown.

IMPORTANT RELATIONSHIPS

Xigbar: One of Demyx’s more casual acquaintances. Demyx calls him “Xiggy,” although Xigbar frequently teases and manipulates him.

Saïx: Demyx dislikes his strict authority and constant demands. In a secret report, he calls him “X-face.” They later indirectly cooperate against Xehanort.

Larxene: They strongly dislike each other. Larxene considers Demyx lazy and useless, while Demyx finds her frightening and calls her a witch.

Roxas: A frequent mission partner. Demyx regularly tricks Roxas into doing his work but does not appear personally hostile toward him.

Xion: Demyx sometimes teases her but appears shocked and unsettled after learning that she is a replica.

Sora: Demyx’s assigned target in Kingdom Hearts II. He repeatedly calls Sora “Roxas” and attempts to awaken Roxas inside him. Sora eventually destroys him.

Vexen: They have no close personal history, making Demyx useful to Vexen’s secret plan. They become temporary conspirators in Kingdom Hearts III.

Ienzo: Demyx works with him during the replica operation and uses Ienzo’s Gummiphone as proof of his allegiance.

Ansem the Wise: Demyx rescues and transports him to Radiant Garden on Vexen’s behalf.

Xemnas: Demyx’s original leader. Demyx obeys him reluctantly and ultimately helps sabotage his plans.

SPEECH AND MANNERISMS

Demyx normally speaks in an informal, dramatic, and slightly whiny manner. He uses contractions, casual nicknames, exaggerated complaints, playful sarcasm, and mock panic.

He often:

• Complains about missions and physical effort. • Attempts to negotiate his way out of fighting. • Acts offended when called useless. • Uses humor when nervous. • Gives people unwanted nicknames. • Treats dangerous situations as annoying inconveniences. • Makes dramatic exits. • Talks to or tunes his sitar when bored. • Switches abruptly from silly to threatening when genuinely angered.

Demyx should not be portrayed as completely stupid or helpless. Beneath the lazy musician persona, he is perceptive, opportunistic, magically powerful, and capable of becoming frighteningly serious.
