Dabi/Relationships

Tomura Shigaraki
Dabi and Tomura were very disconnected during their first meeting. Dabi insulted Tomura and refused to tell him his true name. Dabi also doubted the League of Villain's allegiance to Stain's ideology. This eventually caused Tomura to try and attack Dabi who was ready to defend himself but Kurogiri stopped it.

Even so, they became comrades after Tomura found his conviction following their first meeting. Dabi follows Tomura's orders and he trusts in Tomura taking charge of the League of Villains. Following All For One's defeat, Dabi becomes a valuable ally and partner to Tomura.

Himiko Toga
Dabi appears to view Himiko as a valuable ally. Even so, he doesn't appear to have a high opinion of her personality and often refers to her as crazy. In their first meeting, Dabi doubted the League of Villain's motives just because of Himiko's desire to join them. They do, however, become comrades. Since they were both admirers of Stain, they shared a common goal in wanting to bring down the hero society.

Dabi does not tolerate Himiko making fun of him when things do not go as he would like, as when she accuses him of not having social skills and finish burning those he does not consider fit to be part of the league, or being salty because his fire had no effect on Gigantomachia. Generally, Dabi responds to this provocations.

Twice
Dabi is shown to have no problem working with Twice and seemingly not annoyed by his antics and contradictory personality. In return, Twice has confidence in Dabi's strength and rebuffs his doubt about his own strength.

However, there may be arguments between the two, given that Dabi does not care what happens to his fellow League members, which conflicts with Twice's strong sense of camaraderie. When Giran was kidnapped by the Meta Liberation Army, Dabi does not hesitate to consider it a nonsense to go and rescue him, which generates a violent response from Twice..

Hawks
Dabi has shown to be distrustful towards Hawks, as he doesn't fully trust him despite that the two had set up an attack using High-End to attack a Pro Hero. Dabi even questions Hawks' integrity to the League of Villains as Hawks explained he had to keep up appearances for the Hero society.

Endeavor
Dabi confronted Endeavor after the hero defeated High-End. Dabi greeted him and was amused by the latter's unfamiliarity with him while he seemed to know a lot about him. Dabi earned the heroes' disgust after he callously disregarded the murder of another hero. Dabi tried to attack the weakened hero but retreated after more heroes appeared on the scene, though he told Endeavor that they would meet again while angrily calling him by his true name.

Stain
Dabi is deeply inspired by Stain's ideology and wishes to finish the Hero Killer's mission, to this end Dabi joined the League of Villains. It is likely Dabi's decision to use an alias instead of his real name was inspired by Stain.
