Kotaro Higashi is a Japanese photographer investigating an alien sighting in America.


Kotaro was a reporter from Japan with an interest in revealing the truth, no matter the cost. He travelled to America to investigate a bank robbery perpetrated by a pair cloaked beings with glowing eyes. When his colleague Dave pointed out the pointlessness of it, Kotaro went on his own way.

The reporter later came across an odd exchange in an alleyway, where two men appeared to be arguing. One fled when Kotaro discovered a mysterious vial, while the second man's eye's began to glow and he punched through Kotaro's stomach before fleeing. However, the reporter miraculously survived the assault and lay on the street cheering.

Kotaro finds he is surrounded by several broken, mysterious vials and decides to investigate. After replacing his blood-soaked shirt, Kotaro comes across a woman and a purse-snatcher. With incredible speed, Kotaro catches up and jumps over the purse-snatcher, who is shocked and flees without the purse. Kotaro is called a hero by the woman and inspired by this, Kotaro returns to Dave's with rolls of fabric with him, deciding to become a superhero. With Dave's help, Kotaro tests his abilities and finds out that along with super speed and agility, he has super strength but the two flee after encountering a police car. Kotaro recounts his encounter with the alien and ponders if the drug in the vials gave him these abilities. He shows Dave the drawing of his own Ultraman suit and reveals he added horns to it because it looked cooler.

As 'Ultraman', Kotaro helps prevent a robber from escaping. He then helps the police capture a human under the effects of the mysterious drug, and leaves to have Dave help cool him off due to the fact that using his powers causes his body to produce steam and increases his body temperature. After saving a group of hostages, Kotaro returned to Dave but is confront by a group of drug-powered humans and Alien Druz who had Dave captured. After discovering that Kotaro isn't Ultraman, Alien Druz revealed to him that his existence had 'thrown a wrench' in the Dark Star's plans. When Kotaro tried to save Dave, he is knocked down and Alien Druz killed Dave. Enraged, Kotaro erupted in a blast of flames as he manifests as a flame-like entity, killing Alien Druz and his lackeys. Kotaro awakens in his bed, having been saved by Alien Adad and Red, the latter two reveal what happened. After watching the Star of Darkness' reveal, Kotaro decides to help the two in order to protect everyone. Kotaro reveals to the two that in Japanese, his name contains the character for 'Light' and he believes he doesn't deserve it, asking them to refer to him as Taro.
