Cumanga
A fabulous creature from Brazilian traditions.
The cumanga is a feminine version of the werewolf, possessing one particular trait: her head can detach from her body and fly like a ball of fire. The sight of this phenomenon is so horrifying that it drives witnesses to madness.
According to legend, the cumanga is a woman who engaged in forbidden relations. According to other versions, she is the seventh daughter of an illegitimate union.
