Tetsuya resembles his other counterparts including his signature dark brown hairstyle with semi-curls standing upright. He has brown eyes and has chiseled features. His clothes include his blue civilian clothes with a dark blue jacket and an occasional scarf. His pilot suit includes a dark skin suit with red padding as well as a helmet resembling the head of Great Mazinger.
Tetsuya is a hot-headed fighter who strives to become a hero as envisioned by Kenzo Kabuto. However, he can be overly violent and reckless making Tetsuya take unnecessary risks that have even gotten him killed. Because of the memories he inherits from his clones when they die, it is difficult for Tetsuya to establish his own identity. However, when Tetsuya found out he was a clone it caused him immense grief.
As a genetically engineered human designed for combat, Tetsuya is well versed in combat and piloting.
Tetsuya has a body that is in the peak of a human being, allowing him to pilot the Great Mazinger while resisting the g-force the robot gives off. Through continued training with Jun, he is a powerful combatant in close quarter combat. He is able to heal from minor injuries in a matter of minutes.
Tetsuya possesses numerous clones created by Kenzo Kabuto in the eventual event Tetsuya is dead or beyond repair. The clones are engineered to inherit Tetsuya's memories the moment the current one had. They are also engineered to not recall dying, which makes Tetsuya think he can heal from serious injuries. This however makes Tetsuya reckless, believing himself to be invincible.
Tetsuya is a highly capable pilot well versed in the Great Mazinger, piloting the giant robot to its utmost potential through the Mazin Power and even to transform it into the Great Mazinkaiser.
