Ultra Boss Killer

Because of an accidental crossing to the Ultra World, his soul collided with a comet during the crossing and became the first-generation comet monster Dorakao. As a monster, Aisin didn't want to enter the earth to deliver food, but Dorakao's soul had not yet merged with him, and he couldn't completely control the monster's body. He could only watch his body follow the guidance of instinct and fly to the earth... He originally thought he was dead. Even if he was not killed by Red King, he would be killed by the first generation Ultraman. However, when he was dying, things took a turn for the better! ... A black hole appeared in front of Aisin who became Dorakao, and the huge gravity pulled him and Red King into it...
