Biography
In the past, the Titans were once a race of peaceful giants who had their own planet. They lived in harmony and were worshipped as gods by lesser beings. All of that changed when King Titan turned into a power-hungry tyrant who wanted to conquer the entire universe with his immense power, manipulating and corrupting his own kind. When his plans were revealed, a massive war broke out. King Titan enslaved thousands of planets and set out to conquer as many more as he can. Finally, when they discovered Earth, it was already dominated by the Combine. Being their arch enemies, they defeated the isolated units and conquered Earth. His reign of terror had ended when one of his associates broke free of his control and joined the remaining human forces to stop the delusional power-hungry Titan. He was brutally killed before resurfacing as a cyborg. His reign of terror has been permanently stopped and all the planets he had previously conquered have been freed from his control.
