Dolly is a clone—specifically, a prototype of Misaka Mikoto—who first appeared with medium brown hair styled with front bangs and a distinctly middle school appearance. She originally wore a small black tank top and had a visible life-support device embedded in her body, along with scars scattered across her skin that marked her origins as an experimental subject.
After her memories and knowledge were transferred to a new clone body, Dolly's physical appearance changed noticeably. The scars disappeared, and she developed longer hair, which she's kept even after escaping the facility. The resemblance to Misaka remains unmistakable, though her improved condition makes the differences between them more apparent than before.
