Nine is an arabic numeral nine. They have a very light gray body and slightly lighter limbs. They wear black sunglasses shining with the colors of their skateboard they carry around; light blue, cream and yellow. Nine's personality appears to be based upon the exaggeration of the skater subculture in the late 1990's and early 2000's, using slang such as "tubular", having sunglasses, and owning a skateboard, which was very popular around that time period.
