After Hercules was driven mad by the goddess Hera and killed his family, he was forced to complete twelve labors as repentance. There were originally 10 labors, but Hera tricked King Eurytheuses into making him to replace two, because Heracles had help and also because he had cheated (in their eyes; using rules that they made up after the labor).
- Slay the Nemean Lion.
- Kill the 9-headed Lernean Hydra.
- Capture the Cerynian Hind of Artemis.
- Capture the Erymanthian boar.
- Clean the Aegean stables in a single day.
- Kill the Stymphalian Birds.
- Capture the Cretan bull.
- Steal the Mares of Diomedes.
- Obtain the girdle of the Amazon Queen, Hippolyta.
- Capture the cattle of Geryon.
- Steal the golden apples of the Hesperides.
- Capture and bring back Cerberus without using any weapons.
