Though Tolkien's Orcs did have superior technology matched and exceeded only by the Numenorians and Dwarves.
Are of below-average intelligence, although there are exceptions. Are carnivorous, often even cannibalistic. Green is not unknown, though generally not the vibrant green of "Blizzard" orcs ( Dungeons And Dragons orcs are grayish-green). Are of varying colours ranging from sallow to gray to red. (Sometimes taken one step further by actually giving them pig heads, like in early editions of Dungeons and Dragons.) May have tusks. Often have pig-like snouts or upturned noses that resemble pig snouts. While not 'peaceful', they are mostly driven by their fear of Sauron or Morgoth. However, Tolkien's Orcs are of debatable morality.
