Catoblepas is a Soul of Rebirth enemy in Final Fantasy II. They are not highly dangerous enemies if the player has leveled up sufficiently and/or has the Ribbon equipped. They are somewhat valuable, as they drop powerful equipment, most noticeably the Diamond Shield and the Sun Blade.
Catoblepas (from the Greek expression καταβλέπω katablépō meaning "to look downwards") is a legendary creature from Ethiopia, described first by Pliny the Elder and later by Claudius Aelianus. It is said to have the body of a buffalo and the head of a wild boar. Its back has scales that protect the beast, and its head is always pointing downwards due to its head being heavy. Its stare or breath could either turn people into stone, or kill them.
