Kronos (Percy Jackson)

Kronos is the main antagonist of the book series Percy Jackson and the Olympians. While in terms of backstory and personality, he is the lord of the Titans, Cronos, he has the powers of the personification of time, Khronos.

Origin
Main Article: Cronus

Kronos was the youngest child of the sky, Ouranos, but he used a scythe given to him by his mother, Mother Earth, to destroy him and control the universe. He ruled for a long time, but he ate all his children, because he was told one of his children would overthrow him. His wife, Rhea, hid her son, Zeus, and tricked Kronos into eating a rock instead. Many years later, Rhea tricked Kronos into vomiting out his five other children, who joined up with Zeus, who lead them on an attack against the Titans stronghold, Mount Othrys. Zeus used his most powerful weapon, the Master Lightning Bolt, to reduce Kronos to dust, not truly dead. Zeus threw his remains into Taratus, the deepest put on Earth, with the rest of many of the Titans.

The Lightning Thief
In The Lightning Thief, Kronos never physically appeared but manipulated two of the books main villains, Luke Castellan and Ares, God of War. Luke, who was ignored by his father Hermes and had to defend himself from monsters for years, was resentful against the Olympians and Kronos easily convinced him to steal Zeus's Master Bolt and Hades's Cap of Invisibility. He intended for Luke to bring them to Taratus for him to use, but Ares caught Luke. Thankfully for the young demi-god, Kronos convinced the War God that Zeus would blame the thievery of his Master Bolt on Poseidon, causing a huge war. Ares was interested and was manipulated into helping. Cronus then had Ares take the Master Bolt and the Cap.

Instead of having Luke take the weapons to him right away, he decided to give it to an ignorant Percy Jackson, son of Poseidon, who had already been blamed for the theft of the Master Bolt by Zeus. Hades also blamed the son of the Sea God for the theft of his symbol of power and was having several of his monsters stock him. Percy Jackson eventually made it to Camp Half-Blood, the haven for demi-god children, where Luke was, and Cronus decided to have Percy sent on the quest to the Underworld, where he would have the Master Bolt unknowingly, making Hades sure he also had the Cap and that Poseidon was going to try to take over Olympus for himself. He had Luke summon a Hellhound into the boundaries of the camp, which would convince the people at the camp that it wasn't safe anywhere.

Percy was then sent on a quest to the Underworld with his friends Grover Underwood and Annabeth Chase because they thought Hades was the one who stole the Master Bolt. Luke gave Percy winged sneakers, which were cursed so they would pull him into Taratus when they were close enough to it. Half-way through their adventure, Ares gave them a magic backpack, which seemed harmless enough, filled with supplies, but in reality, it hid the Master Bolt inside it and it would only appear when in the Underworld. The plan would've gone perfectly, except Percy didn't want the winged shoes and gave it to his friend Grover. He nearly got pulled into Taratus, but his friends saved Grover from being trapped in the endless pit. Later, after escaping the underworld, Ares tried to take the Bolt from Percy, but the God of War was defeated and gave up the Cap of Darkness. Percy managed to return both symbols of powers, and the Olympians and the half-bloods both realized that Kronos was behind all of these events. Luke then revealed he was a spy and left Camp Half-Blood, leaving the gods and their children to prepare to fight the Titan.
