Emperor Kans

Emperor Kans is the main antagonist of the animated film Krishna Aur Kans. He is the tyrannical and maniacal ruler of Mathura, the brother of Devaki, and the uncle of the god Krishna. He is voiced by Om Puri.

History
Kans was born the son of Emperor Ugrasen and crown prince of the Mathura kingdom. As a result of his poor upbringing, Kans grew up conceited and power-mad, and wreaked havoc across the kingdom, leading his armies in bloody campaigns to increase his power. Kans openly voiced his intentions to spread his influence across the world once he had gained control of the throne.

On the wedding day of Devaki's marriage to Prince Vasudev, a heavenly voice announced that the eighth son of Devaki would kill Kans. Horrified by this prophecy, Kans attempted to kill Devaki, but was stopped by Vasudev. In spite of this, Kans had both Devaki and Vasudev imprisoned, an act that bordered on treason. In response to this, Kans ordered any sympathizers to Devaki and Vasudev imprisoned before seizing power from his father and ordering him locked away as well. Following his ascension to power, Kans was visited by the priest Narad, who advised Kans to seek forgiveness from Lord Vishnu, an act that Kans rejected.

Though Kans initially spared Devaki's first born son, he was convinced by his advisers, Chanur and Mustik, that all of Devaki's children posed a threat to his life, and thus had each of Devaki's children put to death soon after birth. However, Devaki's eighth son, Krishna, was transported to a village to be raised in secrecy. Growing increasingly paranoid, Kans resorted to summoning demons and loosing them on the kingdom to slay his nemesis, with all of these efforts being in vain.

As the years passed and Krishna grew into a young boy, Kans eventually decided to conquer his fears by inviting Krishna to a gladitorial match in his arena. Determined to end Kans' tyranny, Krishna accepted Kans' challenge and arrived in Mathura, joined by his brother Balram. There, they faced Chanur and Mustik in combat. Though the boys initially seemed outmatched, they quickly gained the upper hand against their opponents, and Kans eventually faced off against Krishna himself. Despite his physical strength and demonic powers, however, Kans proved to be no match for Krishna, who slew him in the center of the arena, ending his tyranny over Mathura.
