Hercules and Xena
The movie begins with the Sirens blaring Across The Sea of Time, a song about how Zeus took the Cronus stone from the Titans, had an affair with Alcmena, the wife of Amphitryon (stepfather of Heracles), and had a son named Hercules, who goes on to defeat a Lernaean Hydra at an early age and become a hero.
As the song ends, a giant sea serpent emerges from the sea. Hercules attempts to kill it, finally throwing a giant rock into its mouth. The creature then jumps to the shore and lands on Hercules. Being out of the water, the serpent suffocates and dies. Hercules triumphantly climbs out of its nostrils. While the villagers are thanking Hercules, lolaus climbs out of a rest chair and joins Hercules, who is rewarded by the villagers with a large fish.
Hercules and lolaus head to Thebes to see Alcmene, but Lolaus is upset because Hercules received all the credit. On the way there, they defeat a group of highwaymen and continue their journey unscathed.
Some Satyrs who stole gold from helpless people are in a bar so Xena and Gabrielle come to beat them up and take the money back. Ares shows up after Gabrielle throws wine at a Satyr and beats him up with her fighting stick. He tells Xena to stop Hercules from going to Thebes because there is a trap set up for him there; however, Xena would like Hercules to go since there is trouble and he needs to help. After a while, Xena becomes frustrated with Ares' unwillingness to give up. She and Gabrielle argue about his intentions. There is no rift between them in this movie.
Hercules is pulling a plow at his mother's house. Both of them then see Thor come from the heavens in his chariot pulled by winged horses like Pegasus driving the chariot down. He takes Alcmene to Mr. Olympus, causing Hercules to become disappointed.
Lolaus thinks Alcmene went on her own since she put up no fight but Alcmene disagrees and pushes Lolaus against a wall in his anger. Hercules apologizes and the two head off to go and rescue Alcmene.
Zeus talks to Ares and wonders why he did not stop Hercules. He says that he tried to get a mortal named Xena to do it, and becomes angry when Ares persistently yearns for Xena. Afterward, Hera appears and yells at Zeus for bringing Alcmene to Mt. Olympus. She leaves and steals the Kronos stone while doing so.
Hera summons the titans while Zeus checks up on Alcmene, who has been shrunk and placed in a small Arabian dollhouse to protect her from Hera.
Aphrodite surfs down a mountain, which makes Lolaus very happy, and who hugs Hercules. She tells Hercules that Hera is angry, and not to go to Mt. Olympus for his good. He decides to go anyway. Iolaus stays behind to entertain Aphrodite but leaves as an earthquake starts.
Meanwhile, a small boy has fallen into a lava pit. Hercules holds the colliding ends together while Lolaus pulls the boy up, to the gratitude of the boy's mother, who then takes him to safety,
Xena and Gabrielle, in a nearby town, are battling three thugs. Xena is tasked with stopping a rolling giant rock from falling upon one of them. When she completes the task, both Xena and Gabrielle are shown Hercules meeting the titan Porphyion.
The leader of the titans says that Hera can go free because he is not defending the gods. Zeus calls Artemis, Aphrodite, and Ares together to fight the titans, all while hoping that Hercules will join them.
Xena and Gabrielle are helping wounded people. Artemis decides to ask for Xena's help, promptly turning Gabrielle into a giant bird. Xena rides on Gabrielle to the Gods' home while Hercules is climbing up. Xena explains to Artemis that all she had to do was ask for help from Xena and that she didn't need to turn Gabrielle into a giant bird.
The four titans come to battle; Poprhyrion, Tethys, Crius, and Mnemosyne. Hercules shows up and greets Xena, promptly rescuing Alcmene while leaving everybody else to fight the titans. Hera turns all of the gods into animals; Lolaus and Xena escape by riding on Gabrielle, who is still a bird, to Alcmene's' house. This upsets everybody, as Hera did nothing to help Alcmene. The gods are all small animals until Zeus can get the stone back. Ares is a goat, Aphrodite is a cow, Artemis is a rabbit, and Zeus is a mouse.
