Cupid is the Roman god of desire, erotic love, attraction and affection. He was known as Eros to the Greeks. Cupid was the progeny of Venus (Goddess of Love) and Mars (God of War), which might be why a God of Desire is armed with a militant bow and arrow. You could put adorable heart-shaped tips on it… getting hit by one is still going to hurt like a mother.
He was portrayed by Karl Urban in Xena: Warrior Princess.
