The character known as Crématorium, operating under the alias Dabi, emerges as a central antagonist wielding the volatile Quirk "Blueflame"—formerly labeled "Cremation." This ability conjures searing azure flames surpassing 5,000°F, exceeding the heat of Endeavor’s Hellflame. While incinerating adversaries to ash, prolonged use ravages Dabi’s body, his genetic incompatibility with the Quirk’s output manifesting in charred scar tissue, vocal cord deterioration, and regenerative grafts that eradicate pain sensitivity. Born Touya Todoroki, eldest son of Endeavor, his physiology—inheriting ice-aligned resilience over fire resistance—rendered him unfit to inherit his father’s Quirk. Defying this verdict, Touya clandestinely honed his flames until a disastrous eruption on Sekoto Peak left him presumed deceased. Salvaged by All For One and reconstructed by Dr. Garaki with experimental grafts, he survived with heightened regeneration at the cost of Quirk instability. Discovering his family’s memorialization of his "death" alongside Endeavor’s relentless training of Shoto fractured his identity. Shedding Touya, he embraced the moniker Dabi, vowing to dismantle Endeavor’s legacy. As a linchpin within the League of Villains and Paranormal Liberation Front, Dabi weaponizes Stain’s crusade against hypocrisy to cloak his vendetta. His calculated brutality and detached composure belie a fixation on self-immolation, sacrificing his own flesh to secure victory. In later arcs, he destabilizes hero society by exposing Endeavor’s domestic atrocities, culminating in a climactic duel with Shoto that mirrors their fractured lineages. Dabi spurns redemption, choosing annihilation over absolution. The Quirk’s nomenclature evolved in-universe as "Cremation" shifted to "Blueflame," reflecting both the flames’ chromatic change during puberty and localization adjustments in supplemental media. This revision sparks ongoing debate among enthusiasts, with some sources retaining the original title. Physically, Dabi’s lean silhouette bears jagged burns encircling his eyes, mouth, and neck, hinting at full-body scarring. His pragmatic attire often includes an unzipped black jacket, flaunting his disfigurement as both armor and indictment.
