The manticore is a Persian legendary creature similar to the Egyptian sphinx. It has the body of a red lion, a human head with three rows of sharp teeth (like a shark), sometimes bat wings, and a trumpet-like voice. Other aspects of the creature vary from story to story. It may be horned, winged, or both. The tail is that of either a dragon or a scorpion, and it may shoot poisonous spines to either paralyze or kill its victims.
