On a daring voyage atop a hippocampus, Halia and Zeus set out to find the island of power, sustained by the vast ocean's energy. Along their path, they encounter Antaeus, and a fierce battle ensues. Sensing defeat, Antaeus calls upon his father Poseidon, who summons a colossal wave to engulf Halia and transport her to his city, leaving Zeus temporarily incapacitated.

Within the domain of Poseidon, Halia manages to gain his favor by offering her assistance in safeguarding his city from external threats. In return, Poseidon agrees to guide her to the island of power. However, he seeks a promise from Halia—to be granted Zeus's position once they defeat Cronos. With the agreement in place, they reach the elusive island.

As Halia absorbs the island's power, she experiences vivid flashbacks that unveil knowledge about her original titan abilities. Unlocking a new titan skill, she attracts Cronos's minions, and a thrilling battle ensues, allowing her to put her newfound powers to the test. After emerging victorious, she confesses to Poseidon that she never truly intended to hand over Zeus's position, leading to a heated confrontation between them. Utilizing her enhanced powers, Halia manipulates time, altering the island's past to her advantage, depriving Poseidon of his power source and defeating him. With his trident now in her possession, Halia becomes an even more formidable force.

Meanwhile, Zeus emerges triumphant in his battle against Antaeus, extracting vital information about the island's whereabouts. He arrives at the island just as Halia claims Poseidon's trident. Zeus requests that Halia entrust him with the trident, assuring her that he will safeguard it. Together, they decide to return to Athena's city.

As Halia feeds on the island's power once more, the energy triggers profound flashbacks, revealing even more aspects of her original titan abilities, granting her access to new and formidable skills. With the combined strength of Halia's powers and Zeus's support, they prepare to face Cronos in the ultimate showdown, a confrontation that will shape the course of divine destiny and challenge the very fabric of time itself. In this thrilling saga of gods and titans, Halia's metamorphosis into a powerful force unlocks a destiny intertwined with the fates of Olympus and beyond.
