Otomo

Otomo

At the end of World War II, an unknown scientist was developing a formula similar to the Super-Soldier Serum for the Empire of Japan. When the Allies came for him, the scientist drank the serum. The serum had no immediately discernible effects, as the scientist exhibited no superhuman abilities. Eventually the scientist married and had a daughter. The daughter later died in childbirth and the Japanese authorities took her son, Otomo. The Japanese government made him into a hero, and he became renowned for his proficiency against cybernetic and robot opponents.[1]

However, Otomo was dying because of his powers, so the Japanese made an antidote to save him. The Japanese controlled him with it until Shinobi Shaw synthesized the drug, bringing Otomo into his service. When Shinobi Shaw was deposed by his father Sebastian Shaw, Otomo transferred his allegiance to him.[1]

Sebastian Shaw contacted Otomo in Japan and ordered that he destroy X-51 for him. Otomo agreed, but noted that afterward, his debt would be considered paid in full.
