Hercules was born on Mount Olympus with all the powers of a god, to parents, Zeus and Hera. In this movie Hera has been recast as a loving mother instead of a spiteful stepmother like in Mythological tales. On the celebration of his birth, during which the Olympian gods present the infant god with a multitude of gifts. Zeus himself creates the winged-horse Pegasus as a gift. It seems to be a joyous occasion, although one god is not happy about the new arrival: Hercules's evil uncle Hades, lord of the Underworld. Hades tried to give his gift, a spiked skull-shaped pacifier to Hercules by attempting to stick it into the baby's mouth. Hercules, however, managed to squeeze Hades' hand in order to drop the pacifier before it almost went into his mouth.
Hades wants to take control of Mount Olympus and the world, and he sees that if Hercules chooses to fight when he is older, his plans will be ruined. Knowing that as a god, Hercules is immortal and invulnerable, Hades sends his two lackeys, Pain and Panic, to kidnap Hercules and turn him mortal by means of a magic potion. Although they succeed in the first part of the plan, carrying Hercules down to Earth, they are interrupted by two human peasants (Amphytryon and Alcmene) before Hercules finishes drinking and the final drop falls wasted on the ground. Pain and Panic nevertheless attack him in the guise of snakes, and discover that because he did not drink the last drop he has retained his godly strength and they are beaten back. Amphytryon and Alcmene adopt the child, considering his arrival a gift from the gods since they are themselves childless. Too late, Zeus and the other gods discover the kidnapping. Because Herc is now mortal, however, they are unable to take him back to Olympus.
Hercules grows into a strong but clumsy teenager. He desperately wants to fit in, but as he cannot control his godly strength he only ends up causing havoc and alienating those around him. On one occasion, he accidentally flattens the local market town during a game of discus. His foster parents decide to finally come clean to him about the circumstances of his adoption, showing him a medallion they find that bears the symbol of the gods (Zeus's lightning bolt). Hercules sets off to find his place in the world, and goes to the Temple of Zeus for guidance.
While in the temple, Zeus himself appears (embodying his own statue), and reveals Hercules's origin. He explains that the only way Hercules can rejoin his parents on Mount Olympus is to prove himself a "true hero". A grown-up Pegasus also joins Hercules as a constant companion.
He goes to see Philoctetes (a satyr) a trainer of heroes who initially says he will not train Hercules, having been let down too many times by losers who couldn't go the distance, but changes his mind after Zeus zaps him with a bolt of lightning.
When Hercules has reached adulthood and has passed his training, he sets off with Philoctetes to become a Hero in Thebes. On his way he encounters Megara, who is being pursued by the lecherous Nessus. Hercules then intervenes, defeating Nessus (after a couple of disastrous missteps) and rescuing Megara (who felt she didn't even need his help in the first place.) Phil and Pegasus dislike her. Megara relates the events to Hades, by which he learns that Hercules is still alive and so sends a variety of monsters to kill Hercules, the first of which is the Lernaean Hydra. But Hercules dispatches the Hydra and, during the song "Zero to Hero", is shown to dispatch every other monster Hades sends against him.
By this time, Hercules has become the toast of Greece: famous, rich, and perhaps a little too cocky. He believes himself a true hero, and is distraught when Zeus tells him he has not quite gotten there yet, unsure of what more he can do. Megara (on assignment from Hades) convinces him to play 'hooky', or truant for the day, going on a date. The date is ended by Phil, irate at Herc for skipping training. Phil is knocked off Pegasus, and wakes up in time to learn of Meg's involvement with Hades. He leaves to tell his sure-to-be-devastated protege, not hearing Meg's refusal to help destroy Hercules. Hades then discovers that Hercules loves Megara and uses that knowledge to attempt to take the young hero out of the picture while he attempts to overtake Olympus.
Hercules, ecstatic from the date, refuses to believe Phil's warning about Meg, even hitting him in a flash of blind anger, prompting Phil to quit as his trainer. As soon as he is fone, Hades confronts Herc, offering Meg's safety if the hero will give up his strength for 24 hours (long enough for Hades to conquer Olympus.) Hercules is reluctant to see anyone hurt, but Hades vows that no harm will come to Meg. Herc agrees, and Hades takes the opportunity to humiliate him by revealing Meg's role in his scheme. Enacting his plan, Hades sends a Cyclops to destroy Hercules so that he can't get in the way later on. Hercules has been so disheartened by learning that Meg had been working for Hades, that he doesn't even try to defeat the Cyclops. Meg hurries to fetch Phil, who convinces Hercules not to give up. Using his wits, he is able to defeat the Cyclops and send him hurtling off a cliff.
The monster's fall causes a pillar to topple towards Hercules and Megara pushes him out of the way, taking the impact of the pillar. This in turn causes Hercules to regain his strength because Hades' end of the bargain is now broken. Megara, however, is gravely injured and Hercules leaves her in the care of Phil while he rushes off to thwart Hades' invasion of Olympus. After thwarting the invasion, Hades shouts to him that he's got Meg's soul as his 'consolation prize', and Hercules rushes back to Meg's side, only to find that she had died moments before he got there.
However, he then travels to the Underworld to rescue Megara's spirit. When Hades points out that Meg is dead and belongs in the Underworld now, Hercules makes a deal that he will trade his soul for Meg's. Hades agrees to this - IF Hercules can get her out. To do so he must dive into the river Styx, which swiftly ages mortals upon contact, killing them if they spend too long in there. Hercules nevertheless enters the pool to rescue Megara's soul. He does not die, however, as his selfless act fulfills the requirement for being a true hero and, thus, Hercules regains his godhood. He then defeats Hades by punching him into the River Styx, and returns Megara's soul to her body.
He is invited by Zeus to live in Olympus, which was indeed originally his wish, but he decides rather to live his life on earth as a mortal with Megara. Although he will eventually die, he believes that even an immortal life without Megara would be empty.

Hercules is not seen in Olympus Coliseum until he saves Sora, Donald, Goofy, and Cloud Strife from Cerberus. Sora, Donald and Goofy run back to battle Cerberus so Hercules can escape with an unconscious Cloud.

When they leave, Hercules reveals to Phil that he had already worn out Cerberus by the time Sora and company came to fight him. Hercules later battles Sora in a one-on-one battle in the Hercules Cup. When Sora wins and gains the Hercules Cup, as well as the ability to access the Yellow Trinity Mark, he comments that his heart's strength comes from his friends, and Hercules supports him in it.

At the end of the course, Cloud and Hercules are fighting to the death and Hades intervenes, determined to kill Hercules himself, as Cloud could not finish him off.

Phil then tells Hercules how well Roxas is doing and Hercules says that his person he found couldn't even be here since it will take him awhile to get to the Coliseum.Rock Titan and the Hydra. He gets rather tired but hides his exhaustion from Megara and his friends. When Megara is captured by Hades, Sora and the others offer to find her so that he can deal with the Hydra at hand. After he "kills" the monster, he runs into the Underworld to join the others in saving Meg. He later feels depressed for the destruction of the coliseum at the hands of the Hydra.
Upon Sora's second visit to the destroyed Coliseum, Hercules is still depressed. Hades forces Hercules to join in the tournaments in the Underdrome and uses Megara as threat. Before the finals, Sora and the others encounter their friend Auron, who was being brainwashed at the time. In order to buy them time, Hercules offers to fight Auron one-on-one - to the death. Sora, Donald and Goofy stop the fight by helping Auron regain his will just as Hercules is pinned under his weapon and about to run out of endurance. Angered by the outcome, Hades throws Megara into the Styx and Hercules jumps in after her and so regains his strength by reminding himself that a true hero's strength comes from his heart.
