Ryjkin (portrayed by Jasmin Geljo) is the first casualty of Cube Zero, a prequel to the original Cube film. In the opening scene of the film, we see Ryjkin trying to make his way through the Cube, only to set off a device in one of the rooms. Hoses extend from the walls and spray Ryjkin with what seems to be water at first. However, Ryjkin begins to experience an itching, burning sensation all over his skin. As he scratches the back of his hand, his flesh appears to liquefy and drop off. He wasn't sprayed with water but some form of alkaline solution, which quickly breaks down his flesh. Ryjkin screams as his flesh liquefies and oozes off his bones, through his clothes to the floor.
