What was the Nemean lion?

Answer 1

The Nemean lion was a vicious monster in Greek mythology that lived in Nemea. He was eventually killed by Heracles.

The lion was the offspring of Typhon and Echidna, two gods that were born from Gaia

the mother Earth, to slay Zeus because he had not freed his brothers from the pit Tartartus as he was supposed to and ruled himself, but he later freed them to defeat Typhon and Echidna.

After the lion had been slain, its pelt became a battle spoil and was said to be impenetrable.
