Hercules is the Roman name for the Greek god named Heracles.  His parents were Zeus and Hera.  Hera was mad at Zeus for sleeping with a mortal woman so she put two snakes into Hercules' crib when he was an infant.  Hercules was found with a strangled serpent in each of his hands.  He is included in many myths including his twelve labors. Hercules had to serve King Eurystheus for 12 years as a form of punishment for his murders.  The twelve labors were very challenging and almost impossible but he completed all the tasks and became Greek's greatest hero.
