Sidney George Wilson (born January 20, 1977) also known as Ratboy or DJ Starscream, #0 (or 0), is an American DJ, keyboardist and pianist, best known as the turntablist of the Grammy Award-winning band Slipknot. Wilson was the youngest member of the band until Jay Weinberg joined the band as the touring drummer at the age of 24 in 2014. During his time with Slipknot, Sid's mask has been, for the most part, based on gas masks. During the tours for Slipknot and Iowa, Sid wore various different types of gas masks, including ones that had been customised to resemble skulls. During the Subliminal Verses World Tour, Sid grew his hair long and began to wear various masks that simply resembled skulls, shying away from the gas-mask concept. In promotional photos for All Hope is Gone and the tour for the album, Sid changed his mask again, this time, to resemble a robot, dedicated also for his love of the Transformers franchise. He once again cut his hair short, this time into a Fauxhawk style, and dyed it red. The eyebrows of the mask are able to be controlled by Sid, allowing him to make various expressions.
