Demyx

Demyx, unlike the other Organization members, has a very casual, cowardly, and lazy personality—though this may simply be an act since Nobodies are normally free of all emotion and thus cannot feel fear (though it is known that higher nobodies start to form hearts of their own, given enough time). He runs from many encounters, and he refuses to go searching for a giant Heartless alone. Along with Xigbar, Axel, and Larxene, Demyx is portrayed as one of the more comical members of the Organization, although unlike the other three, who earned their places in that list as a result of their sarcasm and wisecracks, Demyx holds this role because of his laziness.

Despite his laid-back personality and his tendency to sit around, Demyx seems to be on good terms with both Axel and Xigbar, calling Xigbar, "Xiggy" and is often shown talking to him in the Grey Area, and though Axel and Roxas talk about him behind his back, Axel does defend him after Roxas comments that Demyx doesn't do anything, Axel stating that Demyx specializes in recon.

Demyx seems to dislike working as much as he dislikes fighting; he even goes so far as to manipulate Roxas, dumping his missions on the younger Nobody and going off to have fun. He complains about how he "isn't cut out for combat" and also considers sweat "gross". Often, he wishes that Xemnas would not make him fight and says that he'd prefer to stay at The Castle That Never Was or at least be given a recon mission.

Demyx loves eating dairy foods despite being lactose intolerant, he also loves other various snacks like candy, chips, etc.

Demyx loves to sit back and play his sitar. He’s extremely talented musically.

Demyx wears a black cloak similar in style to Xigbar's, with somewhat closer-fitting sleeves and pointed shoulder pads, though Demyx's shoulder pads are more noticeable than Xigbar's. His black gloves and boots are mostly similar to that worn by other members. He has cyan eyes and dirty-blond hair, the latter of which is quite distinctive due to its shape. Demyx's hair has an odd mullet-like style, and he has several individual bangs that fall over his face. He is rather youthful in appearance when compared to many of the other members. He is 6’0 and wears size 13 shoes.

Demyx, aka the Melodious Nocturne, is Rank IX of Organization XIII. Organization XIII is a group of beings called ‘nobodies’ that lack hearts. The organization seeks to open the door to the heart of all worlds, Kingdom Hearts. Under their leader, Xemnas, they carry out missions to get closer to their goal. He controls water, and uses his weapon, the Sitar, as a musical instrument to make water fight for him in battle.

He is a friend of Axel and Roxas, a rare occasion in the organization.

Demyx dislikes Larxene, a mean girl who is Rank XII of the organization. She calls him lazy and useless so he calls her a witch.

He also dislikes combat, and most hard work.
