Appearance
Atomic Samurai boasts a sleek ponytail of lengthy black hair, complemented by deep-set eyes and a well-defined jawline. His facial hair is a neat goatee, and he’s often observed gnawing on a slender piece of wood. His ensemble comprises a crimson hooded cloak adorned with an atom emblem, gracefully layered over an unbuttoned azure haori. Beneath this outer layer lies a classic loose-fitting white robe secured with a white sash and two haori himos. His swords are comfortably stacked on his left side.
Personality
Atomic Samurai possesses a demeanor characterized by arrogance, condescension, and humor. This is evident in his refusal to shake Saitama’s hand, citing his acknowledgment only for the “strong” and insisting on proper greeting only upon Saitama’s ascent to higher S-Class ranks. He is notably sensitive about his age, yet fiercely loyal to his disciples, as demonstrated by his determination to uphold Iaian’s swordsmanship despite the loss of his arm.
Despite his disdain for weakness, Atomic Samurai shows a degree of discomfort when his disciples are belittled. He reserves his respect for figures like Bang and his fellow Master Swordsmen, treating them with humility.
Atomic Samurai takes pleasure in his swordplay, often turning it into a game by taunting monsters and showcasing his skills. His straightforward and humorous nature is evident in his advice, which tends to favor action over intricate strategies.
However, his overconfidence proves to be his main weakness on several occasions. One such instance is his encounter with Black Sperm, where his cockiness leads to his defeat as he underestimates the threat’s multiplying ability. Similarly, his recklessness in facing Melzargard without considering alternative tactics also highlights his downfall.
