Dungeons & Dragons is a fantasy role-playing game that has been popular since the 1970s. It features a variety of mythical creatures, including orcs and ogres. An orc is a humanoid creature with green skin, tusks, and a generally aggressive nature. An OGRE is a large, brutish humanoid creature with a large head and body, and often with two horns. Both orcs and ogres are considered to be beasts in the Dungeons & Dragons universe.
