Cottus (nicknamed The Striker, or The Furious) was one of the three Hekatonkheires, also known as the Hundred-Handed Ones.
Early Life, Imprisonment, Release, and Re-Imprisonment
Cottus was the younger brother of the Titans and Cyclopes, a son of Gaea and Ouranos. Their father, hating them, jailed the Hekatonknieres in Tartarus, where the Elder Cyclopes had already been thrown into. After defeating his father Ouranos, Kronos became the King of Mount Orthys, and kept his promise of releasing the Elder Cyclopes and Hekatonknieres from Tartarus. In return, Cottus and his Hekatonkniere brothers Briares and Gyges, built a magnificent black marble palace for Kronos on Mount Orthys. However, Kronos was later disgusted by all of the unbearable noise that the Hekatonkheires and Elder Cyclopes constantly made, as well as their revolting stench. Hence, Kronos, Hyperion and Atlas (the three most powerful Titans) chained all six of them up, and hurled them into Tartatus once again, this time guarded by Kampê, the most ferocious and terrifying monster in all of Tartarus that Kronos personally hired.
Release by ZeusMany years later, after Zeus freed his elder Olympian siblings from Kronos' belly, they all went down to Tartarus (with Hades' guidance). There, the Elder Cyclopes forged three incredibly powerful weapons for the gods: the Master Bolt (for Zeus), the Trident (for Poseidon), and the Helm of Darkness (for Hades). With these weapons, Zeus killed Kampê, and Poseidon shattered the chains of the Elder Cyclopes and Hekatonkheires.
The First Titanomachy
In return for the service rendered to them, all six of them fought on the side of the Olympians in the Titanomachy. Cottus had massive strength (and he was very proficient at hurling huge boulders), which greatly contributed to the Titans' ultimate defeat. At the final battle on Mount Orthys, all three Hekatonkheires were of great help, throwing so many rocks that the Titans thought that the mountain was falling apart. Since the Hekatonkheires had initially built Kronos' fortress on Mount Orthys, they knew exactly how to destroy it. In the subsequent final battle of the Titanomachy, the Olympians finally overwhelmed and defeated the Titans, including Kronos himself. In the aftermath of the battle, the Elder Cylopes chained up all of the Titans, while the Hekatonkheires forced them to kneel before Zeus. Afterwards, Zeus offers the Hekatonkheires to return to Tartarus, this time as the jailers of the Titans, to which they readily agreed.
- As shown in Percy Jackson's Greek Gods, Cottus was freed from Tartarus by Poseidon, who smashed his chains with his new mighty Trident.
- Cottus and his Hekatonkniere brethren (along with the Elder Cyclops) built all of the palaces on both Mount Orthys and Mount Olympus.
- Cottus only appears in Percy Jackson's Greek Gods.
