Upon Alcmene's death, Zeus asked Hercules to join him in ruling the gods of Olympus. Hercules, still bitter toward his father, couldn't decide. He recalled meeting Apollo, his half-brother, years ago. Apollo gave him ambrosia, which transformed him into a full god. But Zeus chastised his son, saying he was never destined for full godhood. Chagrined, Hercules relinquished his new powers but still fought Apollo to a draw. he then saved young Ariadne from Apollo's treachery. This recollection resolved Hercules' indecision: He agreed to join Zeus on Mount Olympus, where he could do the most good for mankind.
