Jin Bubaigawara, alias Twice, navigated a life fractured by loss and abandonment. Orphaned in middle school when a villain attack claimed his parents, he spiraled into homelessness and solitude. A motorcycle accident at sixteen—culminating in the death of a jaywalking pedestrian—cost him his job and housing, plunging him into despair. To combat isolation, he weaponized his Quirk, Double, crafting clones as companions and partners in minor crimes. These duplicates soon revolted, igniting a nine-day bloodbath as they disputed their identities, shattering his psyche. The aftermath left him tormented by existential uncertainty and recurrent dissociative episodes. Double enabled Jin to replicate people or objects through meticulous measurement, granting clones full autonomy and mirrored skills. Trauma initially restrained him from self-duplication, but overcoming this fear unleashed Sad Man’s Parade—an exponential clone army capable of overwhelming foes. The Quirk’s psychological strain permeated his existence; he relied on a mask to anchor his splintered mind and mute warring personas. The League of Villains offered refuge, forging bonds that defined his fractured identity. His loyalty to Himiko Toga solidified into unwavering devotion—repairing her mask in crisis, shielding her in battle—while Tomura Shigaraki’s leadership provided newfound purpose. Yet this trust proved his vulnerability when Hawks, a hero spy, exploited their camaraderie. During the Paranormal Liberation War, Skeptic’s clones forced Jin to confront his status as the original, briefly unifying his fractured self. This clarity fueled a desperate stand to protect allies, revealing his resolve. Despite this resurgence, Hawks executed him to avert catastrophe, a death that reverberated through Toga and the League. His legacy echoes duality: a casualty of societal collapse who craved belonging through chaos. From solitary orphan to fervent villain, his arc mirrors struggles of identity and allegiance, while his demise underscores the blurred lines between heroism and villainy in a fractured world.
