Kotaro Higashi, an aspiring boxer with no relatives to rely on, joined ZAT. During the first battle, Kotaro's plane was hit, and sent crashing into the ground. Moved by this man's courage, the Ultra Brothers and the Mother of Ultra granted him a new life. The female hero placed his latest son, Ultraman Taro, into Kotaro. Not a second later, Ultraman Taro attacked Astromons. Taro attacked with many punches and kicks, until Astromons struck back with his acidic mist, allowing his to get multiple hits in. Taro managed to use the Storium Ray, however, the massive plant monster was destroyed for good.
