A New Light: Part 1 (新たなる光（前編） Aratanaru Hikari (Zenpen)) is the first episode of Ultraman Dyna.
In the 21st century, humanity's technology had advanced considerably, entering an time known as the Neo Frontier era. Expert trainee pilot Shin Asuka joined the elite team Super GUTS to defend humanity from invaders and deal with supernatural threats all while seeing visions of a mysterious light.
The two top trainee pilots of Training Squad ZERO, Shin Asuka and Takeru Fudou, competed in hand-to-hand combat. To win, Shin cheated by pretending that the instructor had just arrived, allowing him to sneak beneath Takeru and jab him in the crotch using his fingers.
Later, the Super GUTS members Ryo Yumimura and Toshiyuki Kohda ran a recruitment test to join their elite team, an outer space combat simulation where Shin Asuka demonstrates considerable skill at flying and shooting. After a brief and furious battle in which Shin successfully tagged Ryo and Kohda, alien objects called Spheres appeared and began to assault the pilots, destroying a space station in the process. The trainees switched from practice to battle mode to fight them, but Ryo's ship's computer malfunctioned, leaving her defenseless. Before her ship was captured by the Spheres, Shin rescued her, but was soon gunned down himself. Shin ejects, and as he drifted through space, he encountered a strange light and fell unconscious.
Shin woke up at the base of Super GUTS, where he met with another member of the team, Mai Midorikawa, who revealed that he is now a member of Super GUTS. Overnight, Shin dreamed of a Sphere reaching Mars and transforming into a monster, then dreamed of the same strange light enveloping him.
Shin then met up with the rest of the team before they are dispatched on a mission to the TPC Mars Base, which was under attack from the monster in Shin's dream, Darambia. Shin was reckless in the mission and his spacecraft crashed, badly injuring his co-pilot Kouda. He attempted to defend Kouda from outside the ship, while another fleet of Spheres arrived to attack the base directly. Shin refused to give up, until the strange light enveloped him and transformed him into Ultraman Dyna. As soon as Dyna appeared, Darambia was blasted apart from the sheer amount of light created during the transformation. Dyna destroyed the remaining Spheres, much to the amazement of the base's onlookers. It wasn't over yet however, as Darambia's pieces drifted together into a new beast, Neo Darambia.
