Atomic Samurai cuts an imposing figure with his long black hair pulled back in a topknot, sunken cheeks, and sharp jawline accented by a small goatee. He dresses the part of a classical swordmaster—a hooded cloak emblazoned with an atom symbol drapes over an open coat, beneath which lies a traditional samurai gi. He wears waraji sandals and carries a pair of katanas (likely a daito, ōdachi, or both based on their length) sheathed at his left hip. The real standout is his atomic-shaped sword guard, which sets him apart from other samurai.
Personality-wise, Atomic Samurai comes across as proud to the point of arrogance. He famously refused to shake Saitama's hand, making it clear he only respects the genuinely strong and suggesting Saitama could earn his acknowledgment if he climbed higher in the S-Class ranks. He's also the type who doesn't take kindly to being called old, which fans often note adds a petty streak to his otherwise dignified demeanor.
