Masaru Aso
Masaru Aso is the laboratory assistant of geneticist Doctor Mochizuki. He is used in one of Mochizuki's experiments related to the creation of the Neo Organism, enabling him to transform into the grasshopper-like Kamen Rider ZO. He flees to the mountains and lapses into a two-year coma before he is awakened by a telepathic call to protect Hiroshi Mochizuki, Mochizuki's son.
After an attempt to discover the meaning of his transformation at Mochizuki Genetics, Masaru senses that Hiroshi in danger and saves the boy from Doras as ZO. Masaru then reveals himself to Reiko and her karate class. ZO battles Koumori Man to cover Hiroshi and Reiko's escape, but they are sucked into a pocket dimension by Kumo Woman (which was created by Doras). ZO saves them and kills Kumo Woman; Koumori Man snatches Hiroshi, with ZO in pursuit. After he saves Hiroshi, Masaru tells Seikichi that Mochizuki used him in his experiments.
