Razor rain is an atmospheric phenomenon featured on the Syfy television series Defiance. It refers to the sudden storms of debris left behind by arkfall that comes down through the atmosphere as pieces of shrapnel. Such phenomenon are unpredictable and very dangerous. The Irathient known as Sukar was killed by a shard of razor rain that embedded itself in his neck. Joshua Nolan made an emergency broadcast over Raider Radio warning the people of Defiance of an encroaching storm. A young daredevil calling himself "Hot Shtako" went out into the storm with rudimentary armor components for the thrill of it. He likely would have been killed had Deputy Tommy LaSalle not intervened. Tommy himself was injured by a piece of shrapnel that pierced his side. As he put it, "I zigged when I should have zagged".
