Here you can find bitz and parts out of the Warhammer 40,000 Ork Boyz box.
The characteristic Ork distinguishes by distinctive green skin and a robust muscular body. Orks are humanoid, but clumsy by nature. They have an innate preference for violence and brutality, act impulsively and intuitively accept the law of the jungle. An Ork is not really evil. The whole point of his life is to find fulfillment, in what he is doing. So it automatically happens that an Ork with leadership qualities finds himself in corresponding Nob-positions, until he becomes a mighty Warboss who commands all the mobs.
