Nemean was the son of giant Typhon and monster of a snake. When people and monsters loved each other, Nemean would fall from Moon, which was a gift to them. Nemean was half-human, half-monster. In the daytime, he was a fierce lion with golden fur, and by night he was a young boy with golden hair and blue eyes.
The sister of Nemean was Hydra who was also a monster of a snake with nine heads. Her upper body was like girl, pretty and charming, but the other half of her body was like a snake.
Nemean loved Hydra since he was a child. Although they had same parents, Nemean fell from heaven while Hydra was born from their mother.
Unfortunately, the hero Hercules accepted 10 tasks from the King, including killing Nemean and Hydra. Nemean refused to fight with Hercules but to protect his beloved, Nemean decided to beat Hercules. Nemean comforted Hydra saying, “Nobody can kill me except you.”
Hydra deeply loved Nemean and decided to fight Hercules herself even if it meant they had to die together. Although she transformed into a snake with nine heads, she could not kill Hercules and he finally defeated her. After that, Hercules dipped his arrows in her blood.
That night, Nemean found out what Hercules did and he became a fierce male lion. He rushed at Hercules. Hercules pulled out his arrow but the fur of lion seemed to resist any weapons. Suddenly, Hercules remembered the arrows dipped with Hydra’s blood. He shot them at Nemean immediately. Nemean escaped from first two arrows but was shot by the third one. The arrow with Hydra’s blood shot through Nemean’s heart. He transformed into the young man and fell on the ground and died.
Zeus allowed Nemean to return back to heaven and transform him into Leo in the sky.
