- ―Kotaro's henshin call
After Kotaro plants the monster Astromons, from a seed that was given to him by a captain of a ship that Kotora used to work on, he attacked the Kaiju, feeling it was his responsibility for releasing it upon the city, but the monster barley took notice of him and flew away with Kotaro hanging on to it's foot. Soon after trying to fight the monster the monster in the air, Kotaro was knocked of and fell into a soccer field. Kotaro is found unconscious the next morning by a group of children and women. after helping Kotaro get back to his strength one of the ladies gives Kotaro a good luck charm.
Later when Kotaro joins ZAT, he attacks Astromons once again, but this time in on of ZAT's fighter jets. But Astromons proved to be to much and threw Kotaro's plane into a building. Kotaro was then taken to the Land of Light, where he meets the Ultra Brothers and the Mother of Ultra who merge him with the newest Ultra Warrior: Ultraman Taro. The Mother of Ultra then tells Kotaro that she was the lady who gave him the good luck charm and that it was really the Ultra Badge. In the final episode, Kotaro gave the Ultra Badge back to the Lady In Green, separating from Ultraman Taro. However, not long after he separated from Taro, Alien Valkie attacked Tokyo by surprise to get his revenge on Ultraman Taro, without knowing Kotaro had been separated from him. Kotaro fought him with his own human abilities and managed to defeat him by blowing up a nearby gas tank.
In the first 9 episodes, the Ultra Badge flashes to Kotaro indicating he is in danger. Kotaro then just raises the Badge in the air transforming him into Ultraman Taro. Episode 10 and onwards, Kotaro's Ultra Badge flashes causing him to remove the Ultra Badge from his shoulder which he then shouts "Taro!" Taro's rise scene usually follows, regardless Kotaro transforms into his Ultra counterpart.
