Dolly


 * This article refers to the clone. For the Academy City project referenced in volume 3 visit Clone Dolly.

Dolly (ドリー), referred to as Prototype (0号（プロトタイプ）), is a character introduced in Toaru Kagaku no Railgun. She is a clone of Misaka Mikoto, a protoytpe for the Sisters for their mass production. She was a friend of both Shokuhou Misaki and Kouzaku Mitori when they were younger.

Originally deceased at the start of the story, all her memories and knowledge are later transferred to a clone of hers after her old body expired. In spite of this, she is essentially the same person and as such the same character.

Etymology
Her name most likely comes from the legendary sheep known as Dolly, the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer.

Her epithet of Prototype likely refers to her being experimental and to her being a clone that is a prototype for Exterior.

Appearance
Dolly, appears as though she has medium brown hair, with front bangs. When she was first introduced she was wearing a small black tank top. She apparently looks middle school aged. She has a life-support device embedded inside of her body that sticks out from it and has scars on her body. She looks like Misaka Mikoto, implying that she is a clone of hers (albeit a protoype).

Later, after getting all her memories and knowledge passed down to a clone, she no longer has the scars that were present in her previous body.

Background
Though her origins are shrouded in mystery, she is a clone of Misaka Mikoto, a benchmark for the Radio Noise Project clones, but is numbered differently as she is not part of it. Her exact purpose was to research more long lasting clones for mass production, and was given drugs by researchers to gain more data. Moreover, she was also created as an experiment into constructing an information sharing network between the clones, the Misaka Network.

At the same time as this, a sister of hers has been created at the same time, where her memories and experiences are later transfered into her. Dolly never met her little sister, but is told that if she takes her medication then she can help her, and that if they can heal her she can have many little Sisters.

Likely because of her status as a clone and the researchers' neglect of her, her body apparently begins deteriorating, needing machines embedded inside of her as a life-support system. These machines are apparently poorly embedded, easily displaced if she is jolted. There are scars on her body of unknown origin.

She is also part of the Clone Dolly Project, where the Exterior Project, a project to create Exterior, a DNA computer that creates esper powers, that involved replacing Shokuhou Misaki, was being held as well. Kouzaku Mitori was later tasked on becoming her friend, whom Dolly immediately takes a liking to, calling her Mi-chan. Mitori would later visit every day. However, one day she saw Dolly naked and the machines that are upon her while she was being checked up, and from that point on never came to visit her again. This is likely because Mitori later discovers the truth about Dolly and is later beaten up imprisoned afterwards. Regardless, Dolly became depressed, worrying the researchers as she is a valuable research subject. The researchers later request Misaki to brainwash Dolly to make her think that Misaki was Mi-chan in order for them to get valuable data from her. At first, Misaki hesitates and is even horrified at what she sees embedded inside/onto Dolly. However, after hearing Dolly's tragic story from her about the loss of her friend Mi-chan, Misaki eventually acquiesces. A week later, Dolly has come to believe that Misaki is her friend, Mi-chan who has come back to visit her again.

And thus, many days are spent on them becoming friends, and Dolly even shares with Misaki her dream of wanting to see the ocean and to get outside of the research institute. But alas, this dream was never realized. Dolly one day collapses. Misaki becomes worried and in the throngs of her pain, Dolly asks Misaki's name, and thanks her for being her friend, apparently revealing she knew of her ruse as soon as Misaki was unable to demonstrate the same powers as Mi-chan.

Her body apparently had limits which could not be extended even by Academy City's medicine, and was predicted by the researchers who had adjusted their plans accordingly to her lifespan. Dolly later passes away. Her death later has a profound effect on Misaki, who later forces the truth out of the researchers after taking over the entire facility.

Daihasei Festival Arc
A flashback to Misaki and Dolly's past occurs after Misaki is forced to use the Exterior in order for her to force the people in the streets of several kilometers in their car into moving away, enough for her car to move and speed up. Mitori would later have a flashback of Dolly herself after being defeated by Shirai Kuroko.

Trivia

 * Due to their similar serial numbers, fans speculate that Dolly is somehow related to the mysterious Misaka 00000, also known as Full Tuning.
