Misaka's younger sister, known as Misaka Imouto or by numerical designation like Misaka 10032, is one of roughly 20,000 clones derived from Misaka Mikoto's DNA. Created under the Radio Noise Project, the initiative was falsely presented to Mikoto as muscular dystrophy research but secretly aimed to produce military espers. When simulations revealed the clones capped at Level 2-3 power instead of Mikoto's Level 5, the project pivoted to the Level 6 Shift experiment. This involved Accelerator systematically eliminating 20,000 clones to theoretically reach Level 6, a goal Tree Diagram calculated would require killing Mikoto herself 128 times. Physically identical to Mikoto, the clones possess minor distinguishing traits. They typically wear Tokiwadai uniforms without modesty shorts and rely on specialized goggles to visualize electron beams and magnetic fields, compensating for their weaker electromaster abilities. Artistic interpretations often depict them with lifeless eyes, a distinction not noted within the narrative. Accelerated growth via hormones and drugs brought them to physical adolescence rapidly, though their chronological age is younger. Post-experiment, clones like Misaka 10032 adopted personal identifiers such as a heart-shaped necklace for individual recognition. Personality evolved significantly after the experiment. Initially, emotions were suppressed as "unnecessary," leading to monotone speech, third-person self-reference, and a collective identity via the Misaka Network. They viewed themselves as expendable non-humans, unquestioningly accepting their role in the Level 6 Shift. Kamijou Touma's intervention during the climax catalyzed change; his rescue of Misaka 10032 and declaration of her irreplaceability fostered emerging individuality. Subsequently, clones developed distinct emotions, attachments, and preferences. Examples include caring for a black cat (despite animals typically avoiding their electromagnetic fields), protecting chick-shaped snacks perceived as alive, and expressing romantic interest in Touma. They began withholding memories from the network, dieting to appeal to Touma, and displaying territorial behavior toward Mikoto. The collective "Will of the Misaka Network" emerged as a distinct supervisory consciousness. Their abilities center on Radio Noise, a Level 2-3 variant of Mikoto's electromaster powers, enabling basic electrokinesis like controlling electronics or delivering shocks, though lacking Mikoto's precision or voltage. Shared brainwave patterns form the Misaka Network, facilitating real-time data exchange, collective processing, and quasi-telepathic communication. This network provides computational support, such as compensating for Accelerator's brain damage, and can manifest artificial entities like Kazakiri Hyouka. Standard equipment includes an F2000R assault rifle and Metal Eater MX sniper rifle, with weapons proficiency shared network-wide. Chronologically, clones like Misaka 10031 and 10032 fought scheduled battles with Accelerator during the Level 6 Shift, with 10032 surviving due to Touma's intervention. After the experiment ended, surviving clones underwent global treatments for accelerated aging defects, though some remained in Academy City. They reappeared during crises, thwarting Tree Diagram Remnant reactivation and aiding in the Academy City Invasion. Daily activities now include attending festivals, caring for cats, and light conflicts with Last Order over stolen goggles. Unique variants exist: Last Order (Misaka 20001), the network administrator, possesses a childlike physique and genki personality, serving as Accelerator's primary charge. Misaka WORST operates independently with Level 4 abilities, disconnected from network control. Dolly, an early prototype, required cybernetic implants for survival.
