“I am the god of Hellfire, and I bring you FIRE!!!!”
Arthur Brown 1975
The following contains spoilers from My Hero Academia. You have been warned.
Since we were introduced to Dabi, we learned that his quirk has an unusual side effect on his body. In the most recent chapter, it was revealed that even though his flames were far more powerful than Endeavor’s his body cannot withstand the intensity of his fire. The reason for this is because his body is similar to his mother’s in the sense that it is built to withstand extreme cold but it is ill-suited to withstanding extreme heat. This incompatible mixture constantly puts Dabi at high risk of burning himself and has resulted in his many burns and scars. Dabi was the kind of fighter who is better suited to ending battles as quickly as possible. If he is in danger of overheating, Dabi would wield psychological warfare against his opponent until his body cools down.
During the Paranormal Liberation War, we got to see some of the super moves such as Flashfire Fist and Prominence Burn he learned from Endeavor. In addition to these techniques, Dabi engaged in a brutal brawl with his kid brother Shoto. Due to fighting a lot harder than normal, the toll his fire had on his body was harsher than normal. Dabi admitted that he could not longer feel anything and his eyes were producing tears of blood. This is a sign that Dabi’s fresh burns not only caused serious nerve damage but are also making him bleed internally.
Because of his physical restrictions, Dabi is unable to wield his flames at full power without killing himself. Still, even though his blue flames are self-destructive in nature, Dabi is the kind of guy who clearly does not care if his own power can potentially kill him. Dabi seems determined to keep fighting until he turns himself to ash. Sadly, due to the damage his body sustained so far, I don’t think Dabi can keep this up for much longer. However, I think there is a way for Dabi to overcome the limitations of his quirk.
Now that Tomura Shigaraki has the All For One quirk and every quirk All For One accumulated, Dabi can potentially acquire additional quirks that will counter the limits of his blue flames. Not only will this allow him to use his fire at full power, but it will also make Dabi an even more formidable supervillain. I look forward to seeing if this is the case. I will only find out when All For One/Tomura Shigaraki wakes up and is 100% at last.
