DarkWin is a black R6 Robloxian character with a white face and black fur tufts on his head. He wears clothing which have the default Windows XP background for a design, along with a black version of the 2017 Japanese Roblox logotype on the front of his shirt, and Japanese text on the back, specifically the Japanese translation of the text that was on the back of Roblox Guests. He also wears a black eyepatch over his right eye that covers his scars. He twitches and shakes in his idle animation.
