Tatsumaki/Relationships

King
King is one of the few heroes that Tatsumaki respects. She is impressed with King's supposed power and dedication to his hero activities such as when King spent the night in Z-City wiping out monsters. Despite this, she is still willing to berate King when she is annoyed, such as when King suggested contacting Metal Knight to take down the Dark Matter Thieves' spaceship as he does not have any attacks that can reach the spaceship.

Tatsumaki believes that King is the only competent hero as he protected Tareo when he sensed Tatsumaki's Psychic Wave.

Fubuki
Tatsumaki's younger sister and fellow esper. Fubuki highly respects Tatsumaki but believes she would be on top if not for her and Sweet Mask. Tatsumaki highly criticizes Fubuki for having followers and losing to Demonic Fan and Do-S but still saved her from both monsters. Tatsumaki believes her actions make her a great sister and she is unaware of how strained her actions have made their relationship, all while Tatsumaki is also too proud to admit that she genuinely loves her younger sister.

Tatsumaki cares deeply about Fubuki, as she didn't wish for her little sister to participate in any battle believing that she could get hurt. After seeing Fubuki's injuries for healing Genos, Tatsumaki was furious and immediately wanted to know who hurt her sister before she was corrected. Though dismissive and believing that Fubuki can't possibly assist her in battle, Tatsumaki did show a moment of somber when Fubuki declared that she wanted to save Tatsumaki as a hero and was momentarily happy at how her little sister has grown.

Flashy Flash
Flashy Flash and Tatsumaki have an unpleasant relationship with one another just like how she treats other S-Class heroes. However, he appears to not be afraid of her and is willing to scold her back whenever she insults him.

Child Emperor
Despite his confidence in her power, Child Emperor greatly dislikes Tatsumaki's arrogant and selfish attitude and lack of strategical thinking since she thinks she can take on the entire Monster Association and the Human Monster Garou by herself to the point of berating the needs for a whole group S-Class heroes as a support in the operation.

While being polite from the outside, he is not above thinking of her as a brat rather than an adult. However, he seems to be very respectful to her as he offered her some orange juice in one of Yusuke Murata's art. Tatsumaki doesn't seem to like it, but she's not opposing it either.

Genos
Tatsumaki at first had a strained relationship with Genos due to their conflicting personalities. His devotion to Saitama irritated her, especially when he would ignore her in favor of listening to his master. She only ever referred to Genos by his hero name "Demon Cyborg" and smashed him into walls or sent him flying on several occasions. While Tatsumaki's opinion of him wasn't that high, she was still ready to offer him her drink when she was unable to finish it.

However, during Tatsumaki's battle with Psykos and Orochi, Genos intervened to assist her. Tatsumaki was initially annoyed by his interference, but it became apparent that Genos gave her the chance to rescue the rest of the heroes and regain her bearings. Because of this, she sincerely complimented Genos and began demonstrating a newfound sense of respect for him. The two would later cooperate with each other along with Drive Knight in the continued battle against the fusion, and after Tatsumaki was exhausted from over-exertion, Genos carried her out of danger multiple times. When he took damage saving her from Black Sperm, Tatsumaki expressed concern for him and even called him by name. She seemed relieved and amused when Genos explained he had his body's defenses upgraded since she last smashed him into a wall.

Bang
Tatsumaki seems to have some respect for Bang as she stood down when Bang told her to. Bang respects Tatsumaki, but is often irritated by her immaturity and her violent tendencies.

Sweet Mask
Tatsumaki has no respect for Sweet Mask, nonchalantly stating to him that she and the rest of the S-Class hate him and telling him he was too weak to join the strike team for the raid on the Monster Association and that he should stick to the support team.

During the raid when Sweet Mask was informing her of the brainwashed mercenaries he had killed in battle and the Monster Association executive he was currently hiding from, Tatsumaki reiterates his clear lack of ability for this kind of fight and his incompetence in properly dealing with said mercenaries and executive.

Saitama
In their first encounter, Tatsumaki didn't think much of Saitama due to his ranking and would insult him. She was even insulted by him ignoring her. Saitama mistook Tatsumaki for a child due to her small stature and found her to be annoying.

Later, when Tatsumaki was about to punish the Blizzard Group in order to make sure they cut ties with Fubuki, Saitama stopped her. She was frustrated by this and a "fight" between them ensued. After seeing Saitama talking to Fubuki, she began questioning their relationship and when Saitama responded by saying he was merely an acquaintance to Fubuki, Tatsumaki decided to test him in order to see if he is worthy of hanging over her younger sister. During their scuffle, Saitama's capabilities surprised Tatsumaki with her acknowledging his power and having fun fighting him. This surprised Fubuki, as up until Blast, Tatsumaki did not care about the opinion of others but accepted Saitama's words after their battle.

It is revealed in an audiobook that the two actually met in a haunted house at a festival Saitama worked at. Saitama thought Tatsumaki was a lost child and Tatsumaki called him a balding samurai and thought he was a ghost when her powers didn't work on him.

After their fight, Tatsumaki seems to have maintained the advice of Saitama, shown by her trying to act less arrogant and being more amiable, demonstrating that she cares about what he has to say.

Blast
Due to Blast saving Tatsumaki when she was younger, Tatsumaki highly respects Blast. Blast would console Tatsumaki after saving her, telling her that she still has a sister that needs her protection and to ultimately not expect someone to come save her when the time comes. Tatsumaki would unintentionally heed this advice a bit far, distancing herself from everyone but her sister Fubuki. The memory of Blast saving her and his advice for her would provide her with the will to continue fighting Psykos and Orochi despite momentarily fainting due to injuries. The two would later join the Hero Association (not together) and are the two highest-ranked heroes in the association.

She is also capable of recognizing Blast, as when the entity "God" used a perfect illusionary form to get her to work with it, she realized the words "God" said didn't match Blast's and simply asked who it really was before seemingly falling asleep. Blast would later appear and showcase pride in her for resisting its temptations.

Due to her past troubles, Tatsumaki has come to put excessive expectation on Blast due to him saving her. Desiring his respect if she became strong enough, and more advice on how to live her life, secretly acknowledging her current state isn't her ideal.

Psykos
Tatsumaki held a low opinion on Psykos. Upon first encountering each other with Psykos puppetting Gyoro Gyoro, Tatsumaki simply asked if she was the boss before battling one another, easily dealing with Psykos's puppet while also deducing her original body much to the villain's shock. Upon Tatsumaki dragging Psykos out, the two battled with Psykos believing she could win only for Tatsumaki to easily capture her for interrogation for the second hostage with Psykos forced to comply.

Though thanks to Orochi, Psykos escaped and gained immense power after her fusion with the latter, able to seriously harm Tatsumaki until an unknown intervention allowed her to uproot the entire lair. Even so, Psykos still believed she would win, arrogantly declaring she had been chosen as a superior entity due to having been granted additional power by the supposed "God". Tatsumaki instead mocks her by stating that she is helpless without Orochi, also telling her that her idea to devour everything just to be alone is moronic. Tatsumaki's words enraged Psykos and the two continued their battle.
