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 attack Dabi.

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

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

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.

Dabi doubted the League of Villain's motives just because of Himiko's desire to join them. They eventually become close comrades.

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

Hawks
Dabi has shown to be distrustful towards Hawks, as he doesn't fully trust him despite the two had set up an attack using High End against a Pro Hero. Dabi even questions Hawks' alliance to the League of Villains or Hero society.

Enji Todoroki
Dabi met him 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 would try to attack the weakened hero but would retreat after more heroes appeared though told Endeavor they would meet again while calling him by his true name.
