Immense Speed and Reflexes: Atomic Samurai possesses incredible levels of speed and reflexes, being able to cut his opponents to pieces in the blink of an eye without them even managing to react. He was capable of countering many of Melzargard's attacks, which were extremely quick in their own right. His amazing speed was shown again when he defeated a transformed Haragiri, who claimed to be faster than the speed of sound whilst a human. Even though the proximity between his neck and Haragiri's blade was virtually zero, Atomic Samurai still managed to evade the blow, draw his own sword, and then slash him numerous times so quickly that Haragiri appeared to have not moved at all shortly before dying. His sword drawing speed is so fast that even Sonic could not see its execution. He was capable of slicing Rhino Wrestler, a Demon-level monster, so fast that it appeared like he did not even draw his sword out of his scabbard which the rhino-like creature assumed he had not attacked at all and was still talking for a few seconds before turning into smithereens. Additionally, Atomic Samurai has further showcased his tremendous speed in his fight against Black Sperm, a Dragon-level threat, where he was able to slash a large number of clones of the monster into dozens of pieces, in extremely rapid succession.
Immense Strength: Atomic Samurai appears to have an extreme deal of strength, as he is able to easily cut through solid matter with his sword, as well as create a powerful shock wave with a single slash. His strength is said to be "nuclear-powered." Additionally, he was able to slice a monster into several pieces using only his toothpick. During his fight with G5, he was strong enough to cut apart the tough machine but not its extremely durable core, which he did not anticipate.
Enhanced Durability: Atomic Samurai is quite resilient. He was able to survive an onslaught from Black Sperm, a Dragon-level Mysterious Being. Even after being put in a weakened state, he was still strong enough to destroy the roof of the hallway and bring it down on the Black Sperm copies.
Enhanced Stamina: Atomic Samurai has high stamina and endurance, as demonstrated during his battle against Black Sperm, a powerful Dragon-level Mysterious Being. Despite being severely beaten down by the monster, he managed to remain conscious long enough until Tatsumaki interrupted the battle and shielded him with a psychic barrier. Later, after resurfacing with the other heroes, Atomic Samurai was able to continue to fight the remaining high-ranked monsters of the Monster Association, even though he had just been beaten down by Black Sperm earlier.
Master Swordsman: Atomic Samurai is an extremely formidable swordsman, so much so that he is considered to be the Earth's strongest swordsman. Legend even says that he can cut down over 100 enemies with each strike. His sword attacks are so fast and strong that the enemies are slashed into many pieces in an instant without even being able to react. He was also able to cut a monster to bits using a mere toothpick. Additionally, Atomic Samurai was able to partially cut off Black Sperm's body without causing the monster to duplicate using the blunted edge of his sword, while also pummeling him to death. However, his swordsmanship does have a limit, since he cannot slice through the gap between cells, and he can only prevent his sword from cutting blood vessels or organs, not atoms.
Atomic Slash: Atomic Samurai's signature attack. He performs over 100 quick sword slashes within a second, leaving his opponents in pieces. He primarily uses this technique while dashing past the opponent, but has also shown a stationary version in which he slashes everything around himself. Atomic Samurai is the only swordsman in the world capable of performing this technique.
Air Blade: Atomic Samurai slashes with his sword and sends a blade of compressed air at his opponents. He can perform the attack upon drawing his sword, blocking an attack and finishing with the air blade in one motion. He taught this technique to Okamaitachi.
Atomic Beeline Slash: Atomic Samurai does many slashes akin to an Atomic Slash and converges them into a single point slash with his sword in an overhead strike, slicing his opponent. It was first used against the fusion of Psykos and Orochi.
Skilled Teacher: Atomic Samurai is shown to be very skilled at instructing and raising disciples in the art of the sword. This is demonstrated by his three disciples, who are all at the top of the A-Class rank of the Hero Association, right underneath Sweet Mask himself. According to Fubuki, all of Atomic Samurai's disciples would have already been in S-Class, if it weren't for Sweet Mask's gate-keeping.
Equipment[]
Swords: Atomic Samurai carries two swords: a katana and a wakizashi.
Katana: His primary blade has a black hilt with a cross-guard that resembles the Rutherford atom model. His primary sword is a custom-made sword, supposedly crafted by a famous blacksmith. The sword's blade was later destroyed by Fuhrer Ugly's acidic vomit.
Sun Blade: An ancient katana protected by the Council of Swordmasters for generations, and the twin of the symmetrically-named Moon Blade. Nichirin gave the sword to Atomic Samurai for safekeeping, imploring the swordsman to find the paired blade. According to legend, anyone who wields both the Sun and Moon blades simultaneously will obtain unparalleled power as "The Swordmaster." While wielding the Sun Blade, albeit for a very limited time, Atomic Samurai became powerful enough to slice off one of Homeless Emperor's largest energy spheres to pieces and even cut Golden Sperm's arm off, overpowering two of the strongest members of the Monster Association in quick succession.
Wakizashi: Atomic Samurai carries a wakizashi. The weapon signifies that he is a samurai.
Stick: Atomic can use the stick he normally chews on as a weapon.
