Cerberus
Multi-headed hound guarding Hades, mastered under a condition and returned after the labour.

Overview
Pseudo-Apollodorus describes Cerberus as the guardian of Hades with three dog heads, a dragon-like tail and serpent heads upon his back. Heracles’ labour is not a permanent theft. Hades first sets the condition that no carried weapon may be used; the hero finds the creature by the gates of Acheron, uses the lion skin against the biting tail and subdues it with his arms. Cerberus is displayed above and then returned to Hades.
