VLThe Hero Killer's will... I plan to make it a reality.
Template:Character Infobox/Villain Dabi (荼毘?) is a villain affiliated with the League of Villains and a member of the organization's Vanguard Action Squad. He and the rest of his team serve as the main antagonists of the School Trip Arc.
Dabi is a slim, young man with dark, spiky hair. His most striking feature are the large patches of his skin that are purple and deeply wrinkled. The borders between those areas and the rest of his smooth and pale skin appear to be held together by crude surgical staples and stitches. Rows of stitches extend from the corners of his mouth to above his ears, giving him somewhat of a permanent grin. His eyes are also heavily lidded.
He has several silver helix piercings in both ears and a silver triple nostril piercing. He wears dark blue pants that reach above his ankles and a matching coat over a simple white shirt, along with dark shoes. He also sports a belt and what appears to be a small leather pouch around his waist.
Dabi appears to have poor manners, as the first thing he did when he met Tomura was insult him. He was reluctant to introduce himself to Tomura and rudely brushed off Tomura's question about his real name. Overall, Dabi seems stoic, aloof, confident and focused on his tasks, rarely expressing emotion, if ever.
He has great respect towards Stain and his philosophy, which resonated very well with him. He intends to be the one to fulfill Stain's vision of a better future.
Dabi first appears viewing a public broadcast about news of the Hero Killer's capture. Inspired by Stain's ideology, Dabi decides to move towards the organization that was widely believed to harbor Stain's cause: the League of Villains. 
Giran brings Dabi and Himiko Toga to the League of Villains hideout. Dabi comments that the group's leader, Tomura Shigaraki is gross looking. Tomura is displeased with the recruits and immediately asks Kurogiri to remove them. Kurogiri refuses and Giran introduces Dabi as a criminal who hasn't done any flashy crimes but follows Stain's ideology. Dabi says he's unsure about the league's motivations and asks if they would really let a crazy girl like Himiko join.
Tomura asks Dabi his name, but he says he will only reveal it at a later time. Dabi goes on to say he will make the Hero Killer's will a reality. Tomura becomes wildly irritated by Dabi and Himiko's comments about Stain, enough so to attack them. Dabi and Himiko prepare to defend themselves, but Kurogiri steps in and uses his Quirk to stop them from coming to blows. Tomura storms off and Dabi complains about his attitude. Kurogiri asks Giran and his recruits to wait for a proper answer at a later date. 
Days later with most of the Vanguard Action Squad, Dabi looks over the U.A. High camp site and proclaims that they will be a warning flare and that the gallant heroes will be dragged back down to earth, all for the sake of a better future. Being asked by his teammate to allow him to strike early, Dabi asks everyone to shut up and mentions they'll be carrying out the plan once all ten of them have assembled. Ten minutes later on the ground, burning the trunk of a tree with his Quirk, Dabi declares that it has begun.
While the other villains target the students and the Pussycats, Dabi aims for Shota Aizawa. Dabi surprises Shota at the facility and quickly takes him out with a fire attack from behind. Shota dodged the attack though and, after a quick battle, captures and ties up Dabi. As Shota starts interrogating him and threatens him with further torture, having already broken one arm, Dabi's body suddenly becomes liquid and Shota's Capturing Weapon slides through him, before he completely dissolves. Somewhere in the forest, Dabi questions how weak he is, since the clone failed and the fight ended quickly; Twice rebuffs Dabi's claim. Dabi orders Twice to make two clones of him so that he can resume his fight, and Twice complies.
Eventually, Compress manages to capture Katsuki Bakugo and informs Dabi along with the rest of the Vanguard Action Squad. At the rendezvous point Dabi notes that their only action now is to wait for their fellow villains. However, Dabi states that there is no gas or walls of fire to make the escape better. Dabi relents and accepts that plans don’t always go accordingly, Dabi spots the bush Yuga Aoyama is hiding behind, much to Yuga’s fear. Dabi prepares to go and check, however, he stops after Twice informs him that they must also call back Nomu since he only responds to Dabi. Dabi recalls the Nomu. Dabi and Twice wait for their fellow villains to reach the rendezvous point. Himiko has arrived with Dabi asking how her mission went, only for Himiko to reply that she could get the blood of one person. Twice is unimpressed and wonders why Himiko is excited, to which Himiko replies that she found a boy she is interested in. As Himiko and Twice converse, Dabi orders them to keep quiet.
Dabi sees something approaching them; Izuku Midoriya, Mezo Shoji and Shoto Todoroki smash Mr. Compress onto the ground and then apprehend him. Dabi is seemingly displeased while Twice contradicts his knowledge about the identity of the Heroes.
Dabi orders Mr. Compress to move, which he does. Dabi launches his flames at Izuku, Mezo and Shoto. Shoto dodges but Izuku and Mezo are hit and injured by Dabi's flames. As Himiko and Twice fight Izuku, Mezo and Shoto, Mr. Compress prepares to give Dabi the captured Fumikage and Katsuki, only to find that the marbles are not in his pocket. After Mezo reveals that he took the marbles from Mr. Compress, Dabi calls Mr. Compress a fool, but the magician calmly tells him to wait and see what happens.
Soon, Kurogiri arrives to retrieve the Vanguard Action Squad. After Himiko, Twice and Nomu teleport away, Dabi and Mr Compress also prepare to leave, although Dabi is distressed that they do not have Katsuki. However, Mr. Compress relieves Dabi's concern by revealing that the compressed Katsuki and Fumikage were in his mouth all the time and the marbles Mezo stole were Shoto's compressed ice. As Dabi and Mr Compress prepare to leave, Yuga fires his Navel Laser at Mr. Compress's face, breaking his mask and causing Mr Compress to spit out Katsuki and Fumikage.
Mezo is able to retrieve Fumikage; Shoto nearly succeeds in retrieving Katsuki, but Dabi snatches the compressed Katsuki from Shoto. With Katsuki in their grasp, Dabi orders Mr Compress to deactivate his Quirk, to which he does. Fumikage and Katsuki return to normal. Dabi grabs Katsuki as they nearly finish teleporting. Dabi, Mr Compress and Katsuki successfully teleport away from the training camp.
After completing the mission, Dabi is present when Tomura talks to the restrained Katsuki inside the League of Villains' hideout.
After Katsuki and the League of Villains watch a video clip of U.A.'s public apology, Tomura understands why society is criticizing U.A. for their failure and that is because the current Hero society is not just. Spinner agrees that the current Hero society isn’t just since the modern Heroes are only doing their job for compensation and not out of selflessness. Tomura explains that the League of Villains are fighting for a just society and intends to win this battle. Tomura orders Dabi to remove Katsuki’s restrains, although Dabi is unsure since Katsuki might attack; Tomura wants to treat Katsuki as an equal and is aware that Katsuki knows he has no possibility of winning. Dabi has Twice remove the restrains. As Twice removes the restrains, Mr Compress apologizes to Katsuki for forcibly kidnapping him and explains that the League of Villains are not just a group of hoodlums perpetuating crimes nor did they casually abduct him; he goes on by saying that everyone in the League of Villains is shackled by the current society and hopes that Katsuki understands their discrimination.
Katsuki’s restrains are removed. As Tomura approaches Katsuki, Katsuki attacks Tomura with his Explosions. Katsuki tells the League of Villains that it is pointless to try and make him change his mind as he has already been won over by the way All Might looks when he wins. Katsuki says that from the beginning he has dreamed of becoming a Hero and surpassing All Might and nothing they say will change that.
Katsuki tries intimidating his captors, but Dabi along with the rest of the Vanguard Action Squad are not intimidated; Dabi thinks Katsuki is a fool for trying to provoke them.
Suddenly, All Might breaks in with Kamui Wood swinging in and restraining Dabi and the other villains with his Lacquered Chains Prison. Dabi attempts to break free by using his flames, but Gran Torino stops Dabi with a kick.
All For One forcefully activates Kurogiri's Quirk which creates a portal for the League of Villains to escape through. Mr. Compress uses his Quirk on Dabi who has fallen unconscious and turns him into a marble.Dabi along with the Vanguard Action Squad, Tomura and Kurogiri teleport away from the battlefield after Sensei uses Kenji's Quirk to forcefully suck them into Kurogiri's Warp Gate.
After the battle between All Might and All for One, Dabi is seen acting on his own, finding new recruits to expand the League of Villains. He encounters four other villains in an alley who behaved hostilely toward him. Dabi considered the small group of villains as garbage and kills them with his Quirk.
Dabi is driving with Tomura and Mr. Compress to pick up Himiko and Twice, after Chisaki and the Eight Precepts of death are arrested.
Quirk and Abilities
- Shota Aizawa vs. Dabi: Undecided
Dabi is deeply inspired by Stain's ideology and wishes to finish what he started. It appears Dabi deciding to go by another name instead of his real name was inspired by Stain as well (who also did not go by his real name).
Although they have not interacted yet, both Dabi and Himiko were inspired by Stain's ideology. However, Dabi doesn't appear to have a high opinion of Himiko as he considers Himiko to be insane.
Twice is one of Dabi's teammates. It appears that Dabi has no problem working with Twice; Dabi appears to not be annoyed with Twice's antics and contradictory personality. Twice has confidence in Dabi's strength and rebuffs Dabi's doubt about his own strength.
- His alias, Dabi, means "cremation".
- (To Tomura Shigaraki) "The Hero Killer's will... I plan to make it a reality."
- (To the Vanguard Action Squad) "This will just be a signal fire. We'll fill those heroes full of holes... and put them in their place. All for a brighter future."
- (To Shota Aizawa) "Quite worthy of being an instructor at U.A. Ain't that right, hero? Is it cuz your students are so precious? Hope you got what it takes to protect them... See ya later."
- (To Blood King) "Why not get cocky? You're playing right into our hands. The second you lost the initiative signaled your defeat. You've got the top hero-training academy, U.A., and the Symbol of Peace, All Might... the two most trusted foundations of our hero-based society. But now one mess after another is shaking that trust... don't you think that loss of faith will spread like wildfire throughout society? Think about it... how your careless administration keeps allowing attack after attack... you're so weak... you couldn't even stop a criminal organization from abducting your students."
