Demyx
Demyx, the Melodious Nocturne, is number IX 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 (a guitar-like instrument) and uses the power of water. He also controls the Dancer Nobodies.
Role in the Organization
Demyx's role in the Organization's plans is minor. He is sent shortly after Sora awakened from his slumber to find Sora and discover his true disposition. He also contacts Hades, but no deal was made and Demyx promptly flees, passing by Sora and co.. 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, which he reads aloud, 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 musical instruments, which then attackd 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.
Demyx confronts Sora later in Hollow Bastion during the War of 1000 Heartless, greeting Sora in a rather friendly manner. However, Sora and his companions do not return the favor, even claiming that Demyx is unable to fight. Demyx still maintains his personality despite the insult, but when Sora and co. claim that the Nobodies do not have hearts, Demyx's normal carefree aire vanishes, and he attacks Sora 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 member to do so in Kingdom Hearts II.
Personality
Demyx, unlike the other Organization members, has a very casual, friendly, 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. But in his final minutes, his true nature as an emotionless entity is revealed, proving he is no different from any other Nobody.
Fighting Style
Demyx, being a musician, has an unusual weapon in that he doesn't use an actual weapon. Rather, he uses a musical instrument called a sitar, shaped like a Nobody symbol. With it, he controls the element of water in a unique way.
His trademark technique is to summon water forms, in the shapes of varying musical instruments, of varying numbers. Though they are not very damaging on their own, they are threatening in that they must be defeated in a certain amount of time. Along with that, Demyx can also create giant pillars of water, erupting from the ground of nowhere. He can also attack Sora with a barrage of bubbles, like a cannon as well as from the air directly above him.
