The Dada race was in need of six human specimens for unknown reasons. The leader sent the best agent to do the task, Agent #271, to Earth. Dada decided the best place to search for specimens was a Japanese science lab. In order to keep out outside humans, specifically, The Science Patrol, Dada set up many traps. This actually drew attention rather than prevent it. Captain Mura and Ide were on a bus that was driving on a mountain road when, the bus fell off. Fortunately, no one was killed. Ide was sent to hospital when a man crawled out and was taken inside the building by nurses. He told a story about a Dada hunting the scientist in the lab. He tried to escape, but the alien could phase through walls. The man barely survived by running into the emergency room. Just out of luck, Dadas can't phase through the room because it's made of a special shielded alloy. Captain Mura and the woman that survived the crash went to the lab. One of the scientists was possessed by the Dada. The Dada went after the two when Mura managed to contact Hayata. He became the Ultra from M78, Ultraman.
