Tatsumaki is brash, moody, hot-headed, and impatient. She often displays a disrespectful attitude, especially toward those she considers incompetent. She has little tolerance for impertinence, demonstrated when she slammed Genos into rubble for defending Saitama from her verbal abuse. Despite her abrasive behavior, Tatsumaki does stop when corrected, as seen when Bang scolds her. She particularly dislikes being ignored or called belittling names like “brat” or “runt.”

Despite her arrogance, Tatsumaki takes her role as a hero seriously, viewing it as a duty to defeat monsters. She accepts missions from the Hero Association and even seeks out monsters to fight in her spare time when bored. Her one soft spot is for her younger sister, Fubuki, although this manifests as being overprotective and controlling.

Tatsumaki is extremely confident in her psychic powers, often claiming that no monster stands a chance against her. This confidence sometimes leads her to behave nonchalantly during critical situations. However, this arrogance stems from deep-seated trauma from her childhood, which causes her to despise criminals who involve children in dangerous situations.

Her confidence in her strength, shaped by her experiences and her mentor Blast, has led to her independent and stubborn tendencies. Tatsumaki believes she must handle everything herself without relying on others, even to the point of binding Bang, Bomb, and Fubuki to prevent them from assisting her in battle. Fubuki attributes this stubbornness to Blast’s influence, which Tatsumaki recognizes as a “curse” left by him. Despite her tough exterior, Tatsumaki secretly dislikes the fear others have of her and yearns for Blast to one day guide her on how to change her life.

Tatsumaki also exhibits a strong superiority complex, often believing herself to be the strongest hero in the Hero Association. This is particularly evident when she insists that she could defeat Garou in seconds if she were at full power. Even after her defeat against Saitama, she refuses to accept that anyone could be stronger than her. This complex likely developed because Tatsumaki rarely faces opponents stronger than herself.

Her superiority complex also hampers her empathy and humility. Tatsumaki tends to disregard the consequences of her actions, causing significant collateral damage when she loses her temper, as shown when her outbursts caused earthquakes during her argument with Saitama. Her behavior has alienated her from many of her fellow S-Class heroes, who see her as a spoiled brat, much to her frustration.

Due to her past trauma, Tatsumaki is fiercely self-reliant and dismissive of relationships. She believes friendships and connections are unnecessary, which is reflected in her attempts to remove Fubuki’s friends, calling them parasites who hinder her sister’s growth. Tatsumaki’s controlling nature, however, has done more harm than good to their sibling relationship, despite her good intentions.

In the end, Tatsumaki chose the path of a hero on her own, determined to help others despite the terrible things she experienced in her past. While her abrasive personality makes it difficult for her to socialize, she loves Fubuki deeply and is willing to do anything to protect her, though often without considering Fubuki’s feelings. Her pride and self-image as a protective sister have caused further strain between them.

Tatsumaki’s childhood was marked by hardship and isolation due to her extraordinary psychic abilities. At the age of seven, she was taken away from her adopted family by a group of scientists calledTsukuyomi, who were interested in experimenting on her powers. Her parents were compensated in exchange for giving her up. During her time with the scientists, Tatsumaki was tested on and rewarded with candy and toys for cooperating. However, they also confined her in a cell and restricted her from going outside, punishing her by locking her up whenever she refused to use her powers.

Eighteen years ago, when Tatsumaki was 10 years old, amonster outbreakoccurred while she was still imprisoned. Left alone and vulnerable in her cell, she found herself in a perilous situation as a monster approached.

Blast, the top-ranked hero of the Hero Association, appeared just in time to save her from the monster. During their encounter, Blast asked Tatsumaki why she didn’t use her psychic powers to defend herself. Tatsumaki lied, saying her powers weren’t working, but Blast quickly realized that she was holding back on purpose. She admitted that she had pretended to be powerless, hoping the scientists would deem her useless and let her go, reflecting her deep feelings of abandonment after being sold by her parents.

Understanding her feelings, Blast gave Tatsumaki valuable advice, telling her not to expect anyone to save her next time and to become strong enough to protect her only family, her younger sisterFubuki. This encounter with Blast had a profound impact on Tatsumaki, shaping her independent and powerful nature, as well as her protective attitude toward Fubuki.

As the second-ranked S-Class hero, Tatsumaki is one of the most powerful heroes in the series. She is regarded as the strongest esper, with abilities that make her a formidable force against monsters and threats. Her immense psychokinetic powers place her above most heroes, and even among S-Class heroes, few can challenge her. Characters like Gyoro Gyoro and Superalloy Darkshine have commented on her incredible strength, with Darkshine noting that Garou would lose instantly against her at the time. Tatsumaki’s full capabilities are demonstrated during her battles with Psykos and Orochi, where she not only defeats the fusion of these two Dragon-level beings but also distorts Z-City with her telekinetic powers.

Supernatural Abilities

Psychokinesis: Tatsumaki is the most powerful esper in the series. She can effortlessly manipulate and move objects with her mind, including massive constructs like buildings or even the entire Monster Association base. Her power is so immense that she can deflect a barrage of powerful attacks from Boros’s spaceship and return them with equal or greater force. She can also cause large-scale environmental changes like creating storms and twisters. Tatsumaki has demonstrated the ability to sense danger, such as detecting when her sister Fubuki is in trouble, and she can locate other espers, like finding Psykos underground. In combat, she can easily crush enemies or throw them around with her psychic abilities, as shown when she defeated the massive Hundred-Eyes Octopus and crushed it into a ball.

During her fight with the Psykos-Orochi fusion, Tatsumaki’s psychokinetic powers reach their peak. She pulls meteor-sized rocks from the ocean and hurls them at high speeds. She also halts a powerful energy beam attack that could sever the Earth’s surface and lift a landmass, then restrains the fusion entity before twisting its massive body, causing massive distortions across Z-City. Even while weakened, she still has enough power to manipulate the ruins of the Monster Association into a colossal spear.

Flight: Tatsumaki uses her psychokinesis to fly at high speeds. She can move through multiple cities quickly during her fight with Saitama.

Telepathy: Tatsumaki can communicate with her sister, Fubuki, using telepathy.

She can continue fighting even after being severely weakened, showcasing her incredible endurance during the Monster Association arc. After a massive fight with Psykos and Orochi, she manages to remain conscious long enough to assist other heroes in battle before finally fainting from exhaustion.

Fighting Style

Master Psychic Combatant: Tatsumaki is a master of using her psychic abilities in combat. She uses her powers for both offense and defense, and her tactical skills are as impressive as her raw power. She can create distractions, manipulate her psychic signals, and develop strategies to defeat her enemies, such as when she made a decoy to trick Psykos. She also created a technique that deflects psychic attacks, calledPsychic Whirlwind, which she developed during childhood and has continued to refine.

Psychic Binding (念動金縛り, Nen-dō Kanashibari): Tatsumaki can immobilize her targets using her psychokinetic powers.

Psychic Whirlwind (念流廻転嵐, Nen-ryū Kaiten Arashi): This is an anti-psychic technique that allows Tatsumaki to redirect or deflect psychic attacks. By making her psychic signals move in circles around her, she creates a protective whirlwind.

In sum, Tatsumaki’s abilities, both in psychokinesis and combat, make her one of the most dangerous and powerful characters in theOne-Punch Manuniverse. Her immense power, combined with her strategic mind and experience, ensures that she is a force to be reckoned with.
