Tatsumaki, publicly known as Terrible Tornado, holds the rank of S-Class 2 professional hero in the Hero Association. Her youthful look, featuring a petite 150 cm frame, emerald green eyes, and distinctive curly green hair, frequently leads to mistaken assumptions about her age despite being 28. She typically wears a form-fitting black dress with long sleeves and four high-cut leg slits, paired with low-heeled black shoes. Born with extraordinary psychic powers, Tatsumaki was separated from her family at age seven by researchers who paid her parents. Confined within a laboratory, she endured extensive testing, receiving toys or candy for cooperation but was denied outdoor access and locked in a cell when not actively using her abilities. At ten, a monster outbreak caused researchers to abandon her; the hero Blast rescued her during the incident, advising her not to rely on others. This rescue profoundly shaped her decision to become a hero. Tatsumaki exhibits a complex personality marked by arrogance, impatience, and dismissiveness toward most people. She reacts strongly to belittlement, particularly concerning her height or perceived age, and displays limited social skills outside interactions with her younger sister, Fubuki. Despite her abrasive demeanor, she maintains a strong sense of justice and proactively engages in hero activities during personal time. Her reputation coexists with public complaints about collateral damage and Hero Association concerns regarding the destabilizing potential of her power. Her relationship with Fubuki manifests as intensely protective, often interfering in her sister's affairs despite objections. Tatsumaki holds deep respect for Blast due to her rescue. Her dynamic with Genos is contentious but gradually improved; after initially dismissing and attacking him, she developed respect following their collaboration against Psykos and Orochi, eventually addressing him by name and expressing concern for his safety. Interactions with other heroes range from begrudging tolerance to open hostility, especially toward Sweet Mask, whom she openly criticizes for perceived weakness. As the series' most powerful esper, Tatsumaki wields immense telekinesis. Her capabilities include lifting and manipulating massive objects like meteorites from orbit, city sections, and entire landscapes. She generates potent psychic barriers, employs gravitational compression against opponents, and achieves high-speed flight via self-telekinesis. Notable feats encompass halting a bombardment from Boros's spaceship, defeating multiple Dragon-level threats simultaneously, effortlessly dispatching monsters like the Ancient King and Giant Octopus, and elevating the Monster Association headquarters 1,500 meters while protecting captured heroes in psychic bubbles during that arc. Her powers reached near-limitless thresholds when unrestrained, enabling her to twist cityscapes and overpower fused entities like Psykos-Orochi. Limitations include reduced defensive capability during intense offensive actions, vulnerability to head injuries destabilizing psychic control, and ineffective life-force manipulation against strong-willed opponents. Her powers fail against ghosts, which she fears. The psychological impact of her childhood trauma contributes to her distrustful nature and social isolation. Her motivations remain rooted in Blast's teachings about self-reliance and protecting Fubuki, though this often translates to controlling behavior toward her sister. Tatsumaki's story arcs consistently highlight her role as a pivotal defense against existential threats, her gradual if reluctant cooperation with other heroes during crises, and the tension between her overwhelming power and its consequences. Her encounter with Saitama resulted in mutual annoyance initially; subsequent interactions revealed his immunity to her abilities and indifference to her status, contrasting sharply with her typical treatment by others.
