Su Yao awakens as a mutant trapped within an experimental facility in the Marvel universe—a situation demanding immediate answers. When his dormant power finally emerges, he discovers the rare ability to replicate any mutant ability he encounters. His capacity for duplication extends to formidable beings: Orochi, the divine entity known as the Will of the Earth; Wanda, wielder of chaotic magical forces; and the Sun God himself. This unprecedented power triggers urgent responses across the superhero community. Professor X prioritizes locating him to help control abilities that could cause catastrophic harm. Magneto questions a surprising familial connection. Thor considers a fraternal bond. Loki simply observes with intrigue. In a world of gifted individuals, Su Yao's gift stands alone—a threat or salvation nobody predicted.
