Dragons are mythological creatures present in Asian, European and ancient American tales and legends. They usually take the form of a giant serpent or lizard and often have wings. Various types of dangerous breath weapons, such as fire-breathing or ice-breathing, are described in some tales.

Asian-style dragons are more serpentine, usually lack wings and are associated with good luck or incredible strength. European-style dragons are more stout-bodied and winged. Tales of their violence, taste for virgin sacrifices and desire to horde massive amounts of gold and treasure are popular. Dragons are popular in medieval era legends, such as "St. George and the Dragon."
