Orcs are among the largest and strongest of the Greenskin races. They vary a great deal in size and appearance, with the biggest individuals in charge of the rest. Pecking order is established by constant fighting, so only the meanest and nastiest Orcs get to the very top of the tribal ladder. Even the smallest Orc packs a great deal of bone, muscle and bloody-mindedness into a body no taller than a Human’s, but which is substantially broader. Orcs have huge jaws, and tiny foreheads behind which lurk a thick skull and not much in the way of brain.
Orcs live in tribes, a collection of greenskins ruled over by the largest, strongest and loudest individual, who is either known as a Boss, Big Boss or a Warboss, depending on his stature. These tribes might only exist as long as the Orc leading them can hold their fractious elements together, or until a challenger usurps power, invariably slaying the old Boss in a leadership challenge, and moulding the tribe to his own, unique vision. There are many tribes, and they are often colourfully named, after their leader, their deeds or some unusual characteristic or custom exhibited by them. Some particularly infamous tribes include the Ironclaw Orcs, the Red Fang Orcs, the Orcs of the Bloody Hand, and the rarely seen White Orcs of Mount Grimfang.
