Demyx

Demyx the Melodious Nocturne, is Number 9 in Organization XIII. He plays a minor role in Kingdom Hearts II, where he is tasked with tracking down Sora to liberate Roxas' "true disposition". Although he dislikes fighting, he is directed to use "aggressive tactics" against Sora and his companions. He wields a sitar and uses the power of water. He also controls the Dancer Nobodies.

Demyx will be a playable character in the multiplayer gameplay of Kingdom Hearts 358/2 Days.

Kingdom Hearts II
"Organization XIII's Number IX." ''He used a type of instrument called a "sitar" to control water... but he wasn't very good at fighting.''

Demyx was under orders to "liberate Sora's true disposition" while surveying the world of Olympus.

Role in the Organization
Demyx's role in the Organization's plans is minor. He is sent after Sora on suggestion by Xigbar to find him and "liberate his true disposition", that is, to keep Sora on the path Organization XIII wish him to take. He also contacts Hades, but no deal was made and Demyx promptly flees, saying "Run, run away!", passing by Sora and co. and leaving them puzzled at his outburst. Later, Demyx steals the Olympus Stone, and soon encounters Sora within the Underworld once more. Although Sora doesn't understand the meaning of Demyx's objectives, nor why Demyx calls him Roxas, Demyx is unable to fulfill them and took the next ordered step, which is to attack Sora. Demyx at first only summons "forms" of water - water shaped into himself and musical notes, which then attacked Sora, Goofy and Donald - which he controlled with his sitar. He is unsuccessful in defeating Sora with his water forms, however, and escapes instead of continuing the fight.

Death
Demyx confronts Sora later in Hollow Bastion during the Battle of 1000 Heartless, again greeting Sora in a rather friendly manner. However, Sora and his companions' response is hostile, even claiming that Demyx is unable to fight. Demyx still maintains his personality despite the insult, with only a "You shouldn't judge anyone by appearance" in a slightly deeper tone. But when Sora and co. claim that the Nobodies do not have hearts, Demyx's normal carefree air vanishes, and he silences them with a much darker tone and attacks the "traitor" again with all his strength. In the end, however, Demyx is defeated again and fatally wounded. After lamenting his loss, he fades into darkness, the first Organization XIII member to do so in Kingdom Hearts II.

Personality
Demyx, unlike the other Organization members, has a very casual, friendly personality but also cowardly demeanor. In spite of the fact that he holds great power as a member of Organization XIII, he runs from many encounters, including ones with Hades and Sora.

Demyx is much less serious and more carefree than the other Organization members, and seems to take his task of pursuing Sora lightly. He doesn't hesitate to read his orders aloud off of cue cards in front of Sora, nor complain about his distaste for fighting. His cries in battle after being hit are also more characteristic of "yelps" than those of the other members, and are exclamations rather than reactions. In his final battle against Sora, however, his true nature as an emotionless entity is revealed, proving that his light attitude is a farce. Usually Sora does not take him seriously unlike the other members, but in their final confrontation seems shocked at his true essence.

Fighting Style
Demyx, being a musician, uses music to control the water around him and to summon water "forms", objects shaped out of water into musical instruments or copies of himself, which move about the battle area to hit Sora, forcing him to defeat the forms in a certain amount of time to avoid an automatic loss. To this effect, he uses a sitar, which is shaped into the symbol of the Nobodies.

The aforementioned water forms are defeated by simple attacks but are aided with a reaction command that lets Sora grab one of the note-shaped forms and uses to destroy other forms, both the note-shaped and Demyx-shaped ones. However, in the Data Rematch within the Garden of Assemblage in Final Mix+, the time to defeat the forms is constantly 30 seconds and Demyx only summons the water Demyx-shaped forms, meaning the Reaction Command no longer appears and Sora has to destroy the forms manually, even if the number of forms summoned reaches 99. Most players, however, compensate for the loss of the reaction command by using Firaga in normal or Wisdom Form, depending on the number. Demyx also does this continually, often saying "Dance water, dance!" and starting the whole process again after Sora destroys all of the forms.

Along with that, Demyx can also create giant pillars of water, erupting from the ground out of nowhere. He uses this technique in various forms: forming behind him as he jumps through the air, becoming a wall of torrential water that slowly moves towards the opponent, or even forming wildly and rapidly as Demyx swings his sitar about. Demyx can whack Sora with his sitar, but Sora can counter this move with a Reaction Command. He can also attack Sora with a barrage of bubbles, like a cannon as well as from the air directly above him. He also has a habit of playing in battle, initially causing an easy or difficult counter.
