Hercules was challenged to kill the lion. Killing this beast was not easy, the beast was supernatural. Hercules fought it face to face, and throttled it to death with his bare hands.
Labor 4 - The Erymanthian Boar
Labor 1 - The Nemean Lion
For this labor, Hercules was tasked with killing the many-headed Hydra. The Hydra calls on his ally, a crab to help him defeat Hercules. Close to giving up Hercules thinks of calling his nephew, Iolaus for back up. Iolaus comes and they defeat the creatures.
Labor 5 - The Augean Stables
Labor 2 - The Hydra
Labor 3 - The Cerynitian Hind
Hercules was to capture the Cerynitian hind. He hunted this female deer with golden horns for 1 year. He found her in Arcadia and fired an arrow at her not wounding her though, because she was sacred to Artemis.
Hercules was to bring back this enormous boar alive. He located the boar on Mount Erymanthus and immobilized it by driving it into a snowbank.
Hercules was to clean out the stables of King Augeas in 1 day. Augeas had a lot of cattle which had huge quantities of manure. He diverted 2 rivers through the stable yard and got rid of all the manure.
I will make 2 rivers!
Hercules was next challenged to kill the Stymphalian Birds. He could not approach the birds because of the ground, so he used some castanets to make noise causing them to take flight. He then shot them down with his arrows.
