The orks are a race from the fictional warhammer-40k universe. They are described as being muscular humanoids, with green skin and a penchant for violence. The orks live for war and constantly fight anything in sight, including each other. In many ways they are analogous to (and based upon) the orcs of Games Workshop's warhammer-fantasy setting, although differences have emerged as the two universes have become officially separated (to popular opinion). Alongside the Space Marines, Orks are one of the most iconic elements of the Warhammer 40,000 universe.
