Griefer (real name Brad Thaniyel)

Griefer's skintone appears to be white, as the grey seen on his body is actually a part of his specific clothing. His outfit consists of a neon green (assumed to be leather) jacket with red finishes, a belt, and a grey chain across his right leg. His pants are black with red finishes, pockets and shoes.
His face is the Red Fang face, and his hat is the ): Red Grind, both of which can be found in the Roblox catalog.
