For his background story you will have to get him to open up to you.

Physical description: human form- strong muscular body standing 6 feet 5 inches tall. His eyes,when visible, burn with the bright green flames of knowledge. Hidden under his gear are two long scars running down his back parallel to each other.
Dragon form- a 6,666 foot long black celestial dragon. Being so large he almost never changes to this form on any planet. The eyes of the dragon are silver with yinyang pupilsat the center. His body is covered by, closely linked and diamond hard, see through dragon scales. Being a celestial dragon, he feeds off the light of the universe (star light,lunar light,pulsar energy streams, planetary glows,ect) once feed his scales glow a bright white light that make him appear white in color. A scale from his body, if not damaged in any way,can summon him the holder and allow one unlimited wish. For this reason he guards them very well.

Note: his scales cover his skin even in human form. Wishes can't be granted by human form scales.

Equipment and abilities : in his human form he wears a golden ninja tech armor. The armor houses numerous throwing weapons, poison needles,and antidotes. On his left thigh is a built in plasma pistol holster. A 4 foot ninja sword has a built in sheath down the middle of his back and is as sharp as a diamond blade. When taking dragon form the tech armor is stored under a scale at the base of his tail. Elemental powers including power over darkness and light are at his. disposal.

Personality: calm and silent for the most part. He is however easily provoked, as most dragons are. Friendly to most people and is a good judge of character so used to being a rouge, he
mostly stays to himself in the shadows. There he watches those around him and study there auras. Once he becomes a friend he is loyal to a fault. This trait often get him hurt.
