Perseus (Clash of the Titans 2010)

Perseus, the legendary founder of Mycenae and of the Perseid dynasty of Danaans there, was the first of the mythic heroes of Greek mythology whose exploits in defeating various archaic monsters provided the founding myths of the Twelve Olympians. Perseus was the Greek hero who killed the Gorgon Medusa, and claimed Andromeda, having rescued her from a sea monster sent by Poseidon in retribution for Queen Cassiopeia declaring herself more beautiful than the Nereids

Perseus was the son of Zeus and Danae, who by her very name, was the archetype of all the Danaans. She was the only child of Acrisius, King of Argos. Disappointed by his lack of luck in having a son, Acrisius consulted the oracle at Delphi, who warned him that he would one day be killed by his daughter's son.

Danaë was childless and to keep her so, he imprisoned her in a bronze chamber open to the sky in the courtyard of his palace: This mytheme is also connected to Ares, Oenopion, Eurystheus, etc. Despite the excessive forms of protection to prevent impregnation of Danae, Zeus came to her in the form of a shower of gold, and impregnated her. Not so long after, their child was born: Perseus.

A fisherman by name of Spyros finds a casket afloat in the sea, bearing a baby still living and clasped in the arms of his mother’s corpse. Spyros and his wife Marmara raise the baby as their own and name him "Perseus".

Years later, Perseus is fishing with his family when they witness soldiers from the city of Argos destroying a Statue of Zeus. The gods, infuriated at this desecration, unleash the Furies - flying beasts who pursue mortal sinners. The soldiers are attacked and slaughtered by the Furies. The Furies merge and take the form of Hades, who destroys the ship Perseus and his family are on. His family perishes, but Perseus survives and is found by other survivors, soldiers from Argos led by Draco.

Perseus is brought before King Kepheus and Queen Cassiopeia who are celebrating the campaign against the gods. The revelry is cut short by the arrival of Hades, who has been given leave by Zeus to punish the mortals for their defiance of the gods. Hades proclaims that in the upcoming solar eclipse, he will unleash the Kraken against Argos unless the Princess Andromeda is offered as a sacrifice. Before leaving, he reveals that Perseus is a demigod, the son of Zeus.

Perseus is imprisoned by Draco and in captivity meets Io who tells him of his origin. Many years before, King Acrisius also tried declaring war against the gods. To punish him, Zeus impersonated Acrisius and impregnated his wife, Queen Danae. Acrisius, driven mad with rage, orders the execution of Dänae and the newborn baby and casts them into the sea in a coffin. As punishment for his continued defiance, Zeus also strikes Acrisius with lightning, transforming him into a monster. Io also reveals that she was cursed with immortality after refusing to give in to Poseidon's advances and has watched over Perseus his entire life, beginning with watching from ashore as his adoptive parents rescue him from the floating coffin, to the present, always protecting him, as he is prophesized to be the only one able to stand up to the Gods.

Zeus is convinced by Apollo, who doesn't trust Hades, to give Perseus a chance and presents him with an enchanted sword forged on Mt. Olympus and a winged horse named Pegasus. Perseus refuses both gifts but a wise Draco puts the sword into safekeeping. Shortly thereafter, they are attacked by Calibos. Perseus barely manages to hold him at bay and is bitten by Calibos in a desperate move. Draco severs Calibos's hand causing Calibos to flee. The band gives chase only to be attacked by Scorpiochs summoned by Calibos’s blood. Although they manage to kill some of them, they are ultimately surrounded by even larger Scorpiochs until they are saved by the Djinn, a band of Arabic desert sorcerers led by Sheikh Suleiman. The Djinn, also wishing for the gods' defeat, lends their aid to Perseus and his hand.

The group arrives at the lair of the Stygian Witches and learns from them that the only possibility for killing the Kraken is with the head of a gorgon Medusa who is residing in a temple in the Underworld. Medusa is able to turn any living creature into stone by making eye contact, and thus capturing her head is essential for battling the Kraken. As they prepare to head into the Underworld, Perseus is approached by Zeus, who offers to make him a god, but when he refuses, gives him a golden drachma which is a fare for Charon, the ferryman of the Underworld.

Perseus, Io, Sulieman, Draco and his remaining men Solon, Eusebios and Ixas arrive at the Underworld and the men enter Medusa's lair while Io remains outside, unable to enter. Medusa kills Solon, (who was shot and falls into the fire), Eusebius and Ixas (who have turned to stone), and wounds the shot Draco. Sulieman and Draco wound Medusa and turn to stone, making the ultimate sacrifice. The badly wounded Medusa is beheaded by Perseus, who takes her head. The rest of the body falls into the fire. As he is leaving the temple, he witnesses Calibos creep up behind and murder Io. Perseus and Calibos engage in mortal combat with Calibos having the upper hand and disarming Perseus. Finally coming to terms with who he is, Perseus picks up the Olympian sword and pierces Calibos through the heart, turning him back into Acrisius in human form restoring him to sanity and humility for one last moment.

After saying his goodbyes to the dying Io, who urges him forward to save Andromeda and Argos before she dissolves into an ethereal vapor, Perseus mounts Pegasus and hastens back to Argos. In the meantime, Zeus has ordered the Kraken's release. The Cult goes to the palace and seizes Andromeda in order to offer her to the Kraken. While Kraken ravages Argos, Hades reveals to Zeus that while they have been surviving on the people’s adoration, he has been feeding on people's fear and his monster has been channeling even more fear. While the gods have become weaker, Hades has now grown powerful enough to take on Mount Olympus and even destroy it in revenge for his betrayal so many years before. Realizing his mistake too late, Zeus can only rely on Perseus.

After defeating the Kraken and Hades, Andromeda falls into the sea and Perseus dives in to save her. When he reaches her, he embraces her with a passionate kiss, indicating that he fell in love with her, and she with him. After reaching the shore and regaining consciousness, Andromeda asks Perseus if he will stay and he says there is someone he needs to talk to, before kissing her again, indicating that he will come back. Getting on Pegasus, he flies to Mount Olympus where he confronts Zeus, stating that he does not wish to be one of them and that any conflict between them has just started. After slamming his sword into the Gods' map and shattering the models of every living person, he leaves and is seen flying on Pegasus over the sea, presumably back to Argos.
