Percy Jackson and the Olympians: Legends

Kronos' true appearance is revealed for the first time. He has brutal golden eyes, black curly hair and a unnerving, long pointy beard. He is 9 feet tall, which is short for a Titan. However, he was very young at the time and would later grow as tall as his huge elder siblings. His voice is described as unspeakably old, cold, and powerful, like knives scraping against stone.

Kronos was the boldest and most ruthless of the siblings, even though he was the youngest. His siblings and children were afraid of his insufferably irascible temper. He horribly punishes those who failed him and rarely gives second chances in times of crisis. Kronos is said to have inherited his mother's "cold and distant" smile, which would not waver while he watched demigods die or cities burn. While looking at him in the eye, it is impossible to tell whether he intends to tell a joke or to start a fight, making him completely unpredictable.

Kronos, after the Second Titan War, rests in Tartarus, waiting and scheming for his return to the mortal realm.
