Immortals: Fenyx Rising - Kottos the All Seeing

Kottos is one of the most powerful bosses in the game, being able to dish out more damage than most of them. He can be found at the end of the Vault of Ares, and his defeat is required to get Ares's essence. Kottos, along with the help of the other Hekatonkheires, worked with the Gods, took down the titans and Typhon. He was then sent to guard the underworld, and was later corrupted by typhon and turned into a statue to guard Ares's essence.
