Ultraseven is the third Ultra to come to Earth. He came to Earth after being sent to map out the Milky Way, but the planet caught his attention. When he arrived, he took on the appearance of a brave man and renamed himself to Dan Moroboshi, and joined the UG. Ultraseven defended Earth from countless alien invasions for an extended period of time, until he went back to the Land of Light after sustaining serious injuries and fatigue.
He has a son named Ultraman Zero, who became one of the most skilled Ultras from the Land of Light.
