Origin: Before mankind existed, the daikaijus known as the Yamatos watched the Earth grow as they continue to safeguard their world. All was perfect and peaceful, until a dark crystal fell from the heavens. Megido was sent to check out the unknown object but the crystal radiated with dark matter and consumed Megido with its corruption and created a dark reflection within his soul. The once beloved brother of the yamatos now became a serious threat and Utsuno clashed with Megido to protect the world. The battle was difficult but Utsuno was victorious and banished his brother that he once knew into the underworld. Megido was sealed away for billions of years screeching in agony and swearing that he will return. After he was sealed away humanity was born and started to expand. The yamatos swear under oath that will not interfere with the lives of the inhabitants and left them in peace. However, Megido isn't a yamato anymore and he influences mankind to start wars to slaughter each other, hoping that the yamatos would break their oath that will destroy his seal but they stood strong. However, this didnt stop him he continued to influence the humans to continue killing each other which will lead to the nuclear age when humans abuse the great power and create monsters that will lead to their downfall. One day all of the Kaiju in the world would fight each other and bring about armageddon and which will force the yamatos to interfere. That day will mark the advent of Megido.
