Blueflame (蒼そう炎えん, Sōen?) is the Quirk used by Dabi. Blueflame grants Dabi fire-based abilities, particularly creating and generating fire from his body at will. However, unlike Hellflame, Dabi's are blue in color as a result of burning much hotter. 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. His flames are powered by his hatred and rage, so the greater his anger, the hotter his flames are.
