In Dungeons & Dragons and related beasts, the orc is a fierce humanoid monster with a bestial, pig-like face and a greenish or brownish complexion. Orcs live in a somewhat tribal society and often keep other humanoids, such as kobolds, goblins, and gnolls as slaves or underlings. Some orcs are capable of magic. There are a few subspecies of the orc, notably the red orc and yellow orc. Orcs can cross-breed with humans, yielding half-orcs; this is rarely done with the consent of the human involved.
