Shuichi Iguchi, alias Spinner, is a reptilian heteromorph with emerald scales and a gecko-like visage, his long pink-purple hair swept sharply backward. Initially donning a costume mirroring the hero killer Stain—sleeveless shirt, bandaged arms, crimson scarf, and broadsword—he later adopts scaled armor and a massive weapon following Quirk enhancements. Born with a Gecko Quirk enabling wall-crawling, his appearance fueled societal ostracization, fostering alienation until Stain’s ideology gave him purpose. Spinner entered villainy through the League of Villains, driven by Stain’s crusade against corrupt heroes. Early convictions led him to spare Izuku Midoriya during the Forest Training Camp Arc, honoring Stain’s judgment of the boy’s integrity. Over time, his allegiance shifted to Tomura Shigaraki, resonating with Shigaraki’s defiance against a society that rejected them both. Though conflicted when the League targeted non-heroic entities like police convoys, Spinner forged bonds with members like Himiko Toga and Mr. Compress, finding camaraderie in shared marginalization. During the Meta Liberation Army conflict, Shigaraki’s decisive victory and vision for societal rebirth cemented Spinner’s loyalty, eclipsing his earlier Stain-inspired ideals. As co-founder of the Paranormal Liberation Front, he accepted All For One’s gifted Quirks—Body Bulk and Scalemail—which amplified his physical prowess at the cost of mental clarity, reducing him to a feral state. Tasked with leading heteromorphs in the Final War, his descent into mindless destruction alienated followers who once saw him as a symbol of their cause. Hospitalized and arrested post-war, scarred by Quirk strain, Spinner received a visit from Midoriya bearing Shigaraki’s final words. Confronting his grief, he acknowledged Shigaraki as both friend and flawed hero, vowing to preserve the League’s legacy through a written account. This resolution intertwined with urging figures like Mezo Shoji to champion heteromorph equality, even as Spinner himself wrestled with his role as an accidental icon. His journey traces a path from Stain-devoted zealot to Shigaraki’s unwavering lieutenant, navigating identity erosion, borrowed convictions, and the weight of becoming a reluctant symbol—a trajectory marked by fractured ideals, forged kinship, and a clawed grasp for meaning in a world that scorned his existence.
