Primate, Ape (Dire)

Sharp teeth fill this large, feral ape’s mouth, and its long, muscular arms stretch to the ground, ending in wickedly curved claws.

Known to many scholars as the gigantopithecus, the dire ape is a much more dangerous and bestial creature than the relatively peaceful gorilla. An adult male dire ape stands 9 feet tall and weighs 1,200 pounds. The dire ape attacks anything that intrudes on its territory, including other dire apes not of its troop, and does not break off the attack until the trespasser is dead or runs off.
