Apollo (aka Phoebus) is the sun-god. Also god of medicine and music; patron of poetry, mathematics, and prophecy. This radiantly beautiful son of Zeus (aka Jupiter) and Leto (aka Latona) is known as the Bright One; king of minstrels; prince of oracles; lord of the golden bow. His first act was to take up his golden bow and hunt down the Python, which upon the orders of jealous Hera (aka Juno), had harried his mother from one end of the earth to the other. The giant serpent fled to its cave at Delphi. But Apollo pursued it into the depths of the cavern and there slew it with his golden arrows. He seized the cave for his own and raised a temple at Delphi, served by oracula priestesses, who were called Pythonesses. Each morning Apollo rose from his couch in his eastern palace, bridled his fiery-maned stallions, and drove the golden chariot of the sun across the blue meadows of the sky, along the path marked by white-winged dawn. Then, finally, he descended among festive pennants of fire and and dipped beneath the western horizon, where he stabled his horses. Apollo is eternally youthful, lovely to look upon, potent in battle, warm-hearted, and cool-thinking. He was beloved of mankind and used his influence very wisely, preaching always the middle way, counseling against excess. Once, his twin sister, Artemis (aka Diana), who always disapproved of his paramours, accused him of hypocrisy. "You preach moderation," she cried, "but you let your own passions run away with you!" And Apollo replied: "I preach moderation in all things- including moderation." It was this sunny jesting quality, combined with serene wisdom, that endeared him to god and man. There was conflicting claims as to which of his sons Zeus loved best, but it is agreed that he entrusted Apollo with more significant powers than any other god.
In "Young Hercules", Morpheus once made a deal with Apollo, where Apollo kept the sun up for a few extra hours. This invariably caused the death of some crops, which got Morpheus in trouble with Demeter (aka Ceres).
During Hercules's studies at Cheiron's Academy, Apollo presided over a trial to determine whether or not Ares (aka Mars) broke Zeus's protection order on Hercules. Along with Athena (aka Minerva) and Hephaestus (aka Vulcan), Apollo was convinced by Hercules that the order was not breached. After the trial was over, Apollo left to "catch some rays". Apollo decided to leave after Hercules told him he was a jerk.
In "Hercules: The Legendary Journeys", Hercules and King Jason stopped a bunch of thugs attacking Apollo's then-girlfriend Ariadne. Apollo offered Hercules information on their father Zeus, and he became friends with Hercules. Apollo then gave Hercules some ambrosia and made him a full god. After Hercules used his new god powers to break one of Apollo's sacred vases, Apollo grew furious at Hercules and challenged him to race on hoverboards. Hercules began to dislike Apollo after Apollo embarrassed Jason in front of the Corinthian troops. Also because Apollo was cruel.Hercules also disliked Apollo's poor treatment of Ariadne. Apollo challenged Hercules to a fight with the stakes being Ariadne's life. Hercules was able to defeat Apollo and save Ariadne
Apollo once again met up with Hercules, when Hercules was given Olympian god status after the death of his mother. Apollo sided with Hera on her takeover of Mt. Olympus and distracted Hercules by setting a school on fire. Hercules later took out Apollo again with one punch when battling Hera for control of Olympus.
In "Xena: Warrior Princess", Apollo sent the priest Tazor to destroy Xena's newborn baby Eve. Tazor used a special sword that poisoned Joxer. Eventually an antidote was found and Apollo's plan was ruined.
In Disney's "Hercules", he is present for the party celebrating the arrival of Zeus and Hera's newborn child Hercules. Apollo, along with the other Gods, was sent to find Hercules, but it was too late as the baby had already been turned into a mortal and was adopted by a mortal family. Eighteen years later, he is seen imprisoned with the other Gods after they lost against Hades (aka Pluto) and the Titans. Luckily he and the other Gods are freed by Hercules.
Hercules wanted a better job for Career Day, so Zeus put Hercules in charge of Apollo's Sun Chariot, which pulls the sun through the sky. However, the chariot was stolen by Pain and Panic, and Apollo, believing that Hercules lost it, began to question Zeus' leadership.
