As a child, Dabi's body was heavily burned in a fire, and yet he survived, however, he is unable to feel pain due to the heavy damage done to his nervous system.
Dabi is on some very heavy painkillers, like heroine or something. This explains his somewhat erratic speech pattern. Nerve tissue around burns is also dead from thermal damage, hence no pain. That's some body horror material though.
Aside from being unable to feel emotions, Dabi literally cannot express sadness even if he wanted to.
Weaknesses. Despite his Quirk's power, Dabi's flames begin to eat away at him and burn his body should he use them for too long, which prevents him from fighting prolonged battles. To counter this, Dabi tends to rattle his opponents and engage in psychological warfare in order to buy himself time to cool down.
During one of his manga fights, he reveals that his burns have actually destroyed his tear ducts, rendering him permanently unable to cry.
Enji Todoroki. The Flame Hero: Endeavor is Dabi's father. Dabi holds a huge grudge against Enji for rejecting him in the past and feeling like he was being used as a tool.
Dabi's mother, Rei, possesses the power to manipulate ice. This ability was latent within him and finally decided to show itself in the Final War arc. Dabi now possesses the power to manipulate both fire as well as ice, just like Shoto.
Cold Resistance: Dabi is resistant to extreme cold or ice-based attacks, a trait he inherited from his mother. This impermeability gave Dabi an advantage during his fights with Geten and Shoto.
As a child, Dabi's body was heavily burned in a fire, and yet he survived, however, he is unable to feel pain due to the heavy damage done to his nervous system. This is what enables him to use his quirk regardless of the burns that affect his body.
Dabi has a small crush on the leader, Shigaraki.
The flames of this Quirk are extremely hot, burning at a temperature of at least 2,000°C (3,632°F), which is higher than that of lava and normal fire, signified by its blue coloration. Dabi's flames were hot enough to burn an entire group of villains into ash in mere seconds.
"With Twice around, my dream had a way better chance of coming true! So of course I'm sad he's gone!" As you can see, Dabi would not be able to cry if he wanted to, but the word is out on whether he would if he could. Dabi made it clear that Twice was more of a tool for him than anything else.
Dabi doesn't hate his family or Shoto. He doesn't blame the family for the abuse but instead assigns blame to Endeavor. He views the rest of the family as victims of Endeavor's abuse.
He enjoys cuddling with him on your back and you almost on top of him, your hand playing with the staples on his hips while he gently plays with your hair/brushing his fingers against your skin. He can be very affectionate when he needs that comfort only another person he trusts with his life can give.
Going berserk, Dabi unleashes the full power of his Quirk, and mainstays of blazes rise up out of the ground, heading right towards Shoto. The heat from the flames is so intense that they even manage to burn Shoto, but Burnin, Kido, and Onima jump forward and use their Quirks to protect Shoto.
1 Shigaraki
All For One is arguably the rarest and most powerful Quirk possessed by any villain in My Hero Academia. This Quirk so thoroughly defines its bearer that he's taken it as his name.
Dabi is afraid of his feelings because of their connection to his flames, but he also uses his feelings to his advantage.
Although he fell into a three-year coma, this was the least of his troubles.
Dabi may have desired affection from his parents, which he did not receive because of (in his mind) Shōto's existence. Following this idea of jealousy, Dabi may blame Shōto for his feelings of rejection and unwantedness.
Dabi usually smells like his body wash and deodorant, which probably has a hint of spice to it. He reeks like a crematorium after he uses his quirk though, and the burnt flesh smell tends to linger on his clothes no matter how hard he tries to get rid of it. Toga usually smells pretty clean, very floral or fruity.
Dabi has blue flames without overheating, and in an area capable of almost covering a city block. Todoroki=1410ºC-1540ºC He probably has blue flames. Dabi=+1400ºC It has blue flames without overheating, and probably at a higher temperature than Endeavor and Todoroki.
My Hero Academia Shows Dabi Cares For His Mother
In episode 17 of season 6, entitled "The Wrong Way to Put Out a Fire," Dabi is seen by himself, thinking of his reveal and his family. It's not what he's thinking that's important, however; it's how he's thinking.
