The massively popular anime and manga franchise One-Punch Man takes place in a world full of superheroes and monsters, with the heroes and villains each in their own organized associations to either save the world or destroy it. The second highest-ranked member of the Hero Association is Tatsumaki, the self-proclaimed Tornado of Terror,. While that might seem like a bold claim, Tatsumaki is still one of humanity's best hopes against the rise of the Monster Association, and we're taking a closer look at this psychic superhero and her role in the hit anime series. Tatsumaki is introduced as an S-class hero only tasked by the Hero Association to deal with threats worthy of her immense power. It is later revealed in the manga that Tatsumaki was taken from her family by the government at an early age so her incredible psychic abilities could be studied after her parents given a vast sum of money to comply.

She is recognized as one of the Hero Association's most powerful heroes. She and her sister are known as the Psychic Sisters. Tatsumaki is a petite woman, commonly mistaken for being much younger than she really is. She has an adolescent face with emerald green eyes, and green hair that naturally curls up on the ends.

The series follows a superhero named Saitama and his disciple Genos who join the Hero Association so they can be recognized as such when they fight various monsters and villains. The Hero Association ranks all of its members by a Class and a ranking within that class. Characters listed are ones noted by the author in the manga profiles, ones that were highlighted in the anime character list, and ones that recur over several story arcs.

One-Punch Man 's "Monster Association Arc" has proven just how powerful the manga's various heroes and villains actually are, with many unleashing powerful, never-before-seen abilities in combat. However, things took a nasty twist for Tornado when Psychos merged with Lord Orochi, which allowed the villain to enhance her significant abilities. At first, it seemed as if Tornado was going to lose to Psychos, as the villain trapped the hero in one of her own barriers and used the pressure to crush her.
