Since her debut in 1964, Medusa's physical appearance has been presented variously as DC Comics' continuities have shifted and evolved. Though she has routinely been depicted with snakes for hair, she has sometimes been shown as bipedal and sometimes with a serpentine lower body. However across continuities, she has consistently been written with the ghostly ability to possess or influence other beings after her physical body has been killed, as well as an uncanny capacity for resurrection after death. Her characterization has been that of a dangerous immortal creature who is at turns both vengeful and sympathetic.
