Nemean Lion

The Nemean lion was a monster in The Titan's Curse. It is known for being one of the beasts fought by Hercules. The Lion was sent by Luke and the General at the National Air and Space museum to stop the group of questing Hunters and Demigods. It battled with Percy Jackson, but was hard to defeat because of its bulletproof and swordproof pelt. Percy eventually defeated it by throwing astronaut food into its mouth to expose it's one unprotected surface, it's mouth.

Spoil of War
The Lion's spoil of war was its pelt. Percy Jackson receives this when he defeats it, and Heracles, in Greek Mythology received it as well.

Greek Myths
In Greek mythology, the Nemean Lion was a task given to Hercules by his cousin King Eurystheus. After hearing his description of the lion, he was able to confront it, and did not use any weapons at first; instead he wrestled it to death. When he tried to cut its skin, though, his knife shattered, so Hercules used the lion's claws itself.
