Psychoman stands as the primary antagonist in the 1984 crossover film. A malevolent psychic, he annihilated the homeland of a psychic girl named Yuri and relentlessly pursues her to Japan. His objective is the global capture of psychics, intending to exploit their abilities for world domination.

Commanding three masked henchmen who abduct psychics, Psychoman wields formidable psychic powers. He achieves flight, projects destructive energy through fiery eye-beams, and utilizes teleportation. His abilities extend to manipulating the environment, such as turning the sky grey during combat. He exhibits profound arrogance, dismissing opponents as "inferior."

Psychoman specifically targets individuals for their unique psychic traits, seeking Shinzo for his incapacitatingly loud cries and Shishimaru for his shape-shifting and fireball attacks. His plan involves transporting captured psychics to New York to power a Statue of Liberty-shaped machine designed for global conquest.

Operating from a New York base, Psychoman coordinates his plan's final stage. He displays impatience with failing subordinates, threatening severe consequences. During the climax, he confronts the protagonists directly at his headquarters. His defeat occurs when Hattori apprehends him and his lieutenant Geller, ending their scheme.
