• Displacer beast - Wikipedia, the free encyclopedia — A displacer beast is considered to be a "magical beast". In the game, it resembles a black puma with a pair of powerful black tentacles sprouting from its shoulders, and two to four additional forelimbs. They are colored blue-black, like a dark panther. The tentacles are tipped with horny edges which can inflict terrible wounds and resemble the club-shaped catching tentacles of a squid.
