The Mighty Hercules S01 E01 Hercules Comes to Earth

In the first episode of this series we see how Hercules came to earth. Since he wins a sporting competition against his friend Theseus, Zeus rewards Hercules by granting his wish to go to earth and fight evil and injustice. Since Hercules would lose his powers on earth, Zeus gives Hercules a "magic ring" which grants him godly strength while on earth.
