Dabi

Dabi (荼毘だび Dabi?), dubbed as Blueflame (蒼炎 Sōen?) by Geten, is a major supporting antagonist in the series, a Villain affiliated with the League of Villains, and was a member of the organization's Vanguard Action Squad. He and the rest of his team serve as the primary antagonists of the Forest Training Camp Arc. He also serves as an antagonist for the Pro Hero Arc.
He later became one of the nine lieutenants of the Paranormal Liberation Front, an organization formed from the remnants of the League and the Meta Liberation Army.
Dabi currently serves as a commander for the "Vanguard Action Guerilla Warfare Regiment: Violet" along with Geten.
Dabi is a fairly tall, pale young man of a slim, somewhat-lanky build, described to be in his early twenties. He has longish, black hair that spikes up around his head, hanging low over his eyes, which are thin, turquoise in color, and heavily lidded. His most striking features, however, are undoubtedly the patches of gnarled, wrinkled, purple skin that cover much of his lower face and neck, all the way down past his collarbone, below his eyes and on his arms and legs. These appear to be attached to the rest of his skin by multiple, crude surgical staples or hoop piercings, making it impossible to tell if these scars were accidental or self-inflicted.
He has several silver cartilage piercings in both ears, and a triple nostril piercing on the right side of his nose. He also seems to be lacking earlobes on both sides of his ears upon close inspection. In his first appearance, he wears a dark blue jacket with a high, ripped collar, and matching pants, cut off above his ankles, a pair of dark dress shoes on his feet. He also has a plain pale gray, scoop-neck shirt, below which a gray belt with a circular pattern wraps around his waist, a leather satchel attached at the back.
When he joins the Vanguard Action Squad, his look is updated, now consisting of a larger dark blue coat with two large metal cuffs at the end of each elbow-length sleeve, and a white stitch design on each of his shoulders, the hem ripped, extending down to his knees. His shirt and belt stay the same, but he replaces his pants with some larger ones of a darker color, and his shoes with black boots.
Around the time of the formation of the Paranormal Liberation Front, Dabi acquires a new outfit to complete his status as one of the nine lieutenants of the organization. Dabi wears a darkish blue long coat with the same white cuffs similar to his previous one. In addition, he dons a white v-necked shirt with white outlines. His stitches not only extends to his shoulder pads but also the kneecaps of his pants. The only things he retains are his silver belt, black boots, and his dark-colored pants. He also has three buttons on both sides of his coat.
Dabi is a stoic, aloof, confident and focused individual who rarely shows emotion. While rather crude and violent, he is actually cautious, choosing to retreat when Mirko arrived to aid Endeavor and made sure not to divulge too much information to Hawks about High-End because of the infancy of their relationship. Overall, Dabi is a highly enigmatic individual who trusts no one, preferring to do things alone and in his own way. He also gives off the impression of knowing more about certain people than he lets on.
Despite his usual expressionless behavior, Dabi finds joy in establishing himself as a villain fighting against what he believes to be false heroes, an ideology proposed by his apparent inspiration, Stain. Dabi is dedicated to Stain's mission and desires to destroy superhuman society, sharing his belief that one person with the necessary conviction can do so. He appears to share Stain's sentiment that Heroes are hypocritical and unworthy of their title, but unlike Stain, he does not seem to seek for a society with better heroes.
Dabi takes pleasure in taunting heroic figures, students, and Pro Heroes alike, sadistically enjoying the pain he inflicts on others, including those he murders. Sometimes, Dabi engages in psychological warfare in order to unnerve whoever his opposition is (while also allowing himself to cool down from his own Quirk's effects). Very pragmatic in battle, he is rather savvy about how heroes operate and will exploit their natural tendency to rescue others. He's not afraid of causing collateral destruction, rarely holding back, even if it puts his allies at risk.
Dabi is intolerant of most people and can be very derisive, being quite rude and condescending to essentially everybody he interacts with. He insulted Tomura Shigaraki immediately after meeting him and constantly does the same to both his allies and enemies. While the League would go on to develop a strong sense of camaraderie, Dabi has remained distant from them for the most part. He has admitted that he doesn't care for Tomura or the rest of the League and that the value he puts on them comes mostly from their ability to bring his ambitions into reality. This selfish way of thinking establishes Dabi as an extreme sociopath.
However, Dabi appears to at least be capable of feeling remorse. While he had no problem killing the Pro Hero Snatch, the latter's words appear to have resonated with him, implying that Dabi has sympathy for those that have lost family due to villains.Overall Abilities: Dabi is a highly capable villain, being one of the strongest members of the original Vanguard Action Squad, as well as its de facto leader. He has the power and the ingenuity to contend with a multitude of Pro Heroes.
Doubles of Dabi created by Twice were noted to be weaker than the actual villain, but they still were enough to hold off both Vlad King and Eraser Head, two formidable Pro Heroes, during the forest invasion.
Dabi was able to easily repel the Bakugo Escort Squad and eventually restrained Katsuki Bakugo by himself with one hand. With assistance from Mr. Compress, Dabi was capable of overpowering and killing Sand Hero: Snatch in their battle on the highway.
After Endeavor and Hawks defeated the High-End Nomu, Hood, Dabi appeared on the same battlefield to confront the top two heroes. Dabi was about to engage the pair, and given the heroes' weakened state, it's possible Dabi would have defeated Endeavor and Hawks, had it not been for the arrival of Mirko, causing Dabi to retreat, through an ally's Warping ability.
During the Revival Celebration, Dabi was able to contend with Geten, one of the strongest members of Re-Destro's Meta Liberation Army, in terms of raw power. Although Geten exploited his body's weakness to his own power, Dabi was able to continue fighting until Geten was forced to leave the area. In his battle with Hawks in the Gunga Mountain Villa, Dabi was able to overpower Hawks with the brute force of his flames.
Keen Intellect: Dabi has shown to be quite smart and strategic. He formed a plan to send doubles of himself to distract the Pro Heroes while trapping students in the forest, suffering three casualties between the villains after capturing Katsuki. Dabi is very observant of everything around him, whether he's reading someone's intentions or Quirks' weaknesses. He easily identified Tomura's personality instability, effortlessly saw through Shota's stoic nature with just a glance, as well as deduce and exploit the limits of Snatch's Quirk.
Dabi is also known for psychologically engaging enemies, questioning their motives and morality during combat. This is an entirely tactical maneuver for buying time since it complements Dabi's weakness of his flames hurting his own body over time.
Cremation: Dabi's Quirk grants him the ability to generate large amounts of highly destructive blue flames from his body. However, Dabi's body has a low tolerance for his own flames and he will get burned if he uses them for prolonged periods of time.
Offensively, Dabi can shoot fireballs, generate flamethrower-like attacks, and release bursts of fire. Defensively, Dabi can burn away attacks and even generate enough flames to form massive walls of fire to surround his targets. He is able to incinerate an entire group of villains in mere seconds.
