The Nemean Lion was one of the many offspring of half-woman and half-serpent Echidna and her husband, the 100-headed Typhon. It lived in Argolis terrifying people. The skin of the lion was impenetrable, so when Hercules
tried to shoot it from a distance, he failed to kill it. It wasn't until Hercules used his olive-wood club to stun the beast, that he was then able to strangle it to death. Hercules decided to wear the Nemean Lion skin as protection, but couldn't skin the animal until he took one of the Nemean Lion's own claws to rip up the skin.
