Toshiro is a young Japanese superhero-in-training and the son of the legendary Japanese superhero, The Seventh Samurai. His superhero identity is the Cyber Sumo, in which he dons a large robotic suit in the form of a sumo wrestler. He first appeared in the episode "Rising Son" and made a cameo appearance in "No Boots, No Belt, No Brero".


Toshiro has black hair and brown eyes (when they're open). He wears a blue Japanese school boy's uniform with a red tie, black shorts, white socks, and black shoes that have brown soles. He often carries a red backpack with him.


Toshiro was very humble and kind, so much so that he proved to be annoying to others and lacked the aggressiveness or assertiveness to be a proper superhero.

After "training" with Manny Rivera, Toshiro became far assertive and aggressive and proved that he had the potential to be a fierce and feared superhero.
