Caco

The name Caco derives from the Ancient Greek word 'kakos' (κακός), meaning 'bad' or 'evil'. In Greek mythology, Cacus was a fire-breathing giant, son of Vulcan, who lived in a cave on the Aventine Hill in Rome. He was known for his thievery and cruelty, and was eventually slain by Hercules.

Due to its negative connotations and association with a monstrous figure in mythology, Caco has never been a widely adopted given name. Its usage is extremely rare and often appears in literary or mythological contexts rather than as a common personal name.
