Great Decisive Battle! The Super 8 Ultra Brothers
During the crisis, when Daigo, Asuka and Gamu transformed into Ultraman to fight giant monsters, Dan and the other Ultra Brothers were encouraged by the words of their wives and memories of their loved ones to join the fight gaining their traditional transformation items. They all transformed at the same time, the four original Ultra Brothers: Ultraman, Ultraseven, Ultraman Jack and Ultraman Ace revived the defeated Mebius. Later they all joined Tiga, Dyna and Gaia against the Giga Khimaira. The Super 8 Ultra Brothers fought without giving up until they damaged heavily the Giga Khimaira, the multi-beast escaped to space. Ultraseven then fired his Eye Slugger, with Ultraman fired his Specium Ray, and the other Ultras later followed, and their beams collided with Seven's Eye Slugger, multiplying it, and they weakened the Giga Khimaira. It was then destroyed by the brothers' beams.
After the brothers returned to Earth, Black Silhouette suddenly appeared to menace the brothers. However, as they felt the hope of the humans nearby they all fired their signature beams at him, destroying him once and for all. The Super 8 Ultra Brothers each returned to their human forms, and returned to their normal lives. In the end, all the Ultra brothers in their respective human forms, were flying in their ships and flew to the Land of Light, in Nebula M78.
It was unknown how Dan demonstrated superhuman powers in the beginning when he saved some kids from a truck but it can be concluded that he was actually another Ultra who lived on Earth but due to residing on Earth for a long time, he lost his memory as he grew comfortable in his human life.
