Shuichi Iguchi, known as Spinner, possesses a striking reptilian appearance due to his Gecko Quirk, featuring green scaly skin, a snout-like face, and slicked-back purple hair. His costume serves as a tribute to the Hero Killer: Stain, notably incorporating a long, tattered red scarf and a massive bundle of blades. Originally a social outcast, Spinner joined the League of Villains seeking a sense of purpose and justice rather than pure chaos. Eventually evolved into a loyal warrior.
