Misaka 19900

Misaka 19900 (ミサカ19900号) is a Sister, a clone of Misaka Mikoto, that appears in Toaru Majutsu no Index. Originally supposed to be killed in the experiment against Accelerator as part of the Level 6 Shift Project, she was later transferred to an unknown organization outside Academy City.

Appearance
She looks the same as Mikoto, although for emphasis, her eyes are drawn in a different way. Like all Sisters, Misaka 19900 wears Tokiwadai Middle School's uniform (though residing in a different country she could now wear a typical attire like Misaka 10777), goggles, and blue-striped panties.

Personality
She has the same personality as most clones, with emotions that have been suppressed as they weren't beneficial to the experiment. Similar to most of the other clones, she likely has feelings for Kamijou Touma and would likely display envy towards the other clones advances towards him.

Background
Not much is known about her, though as a clone she was most likely produced a few months prior to her introduction in the story.

Toaru Majutsu no Index Light Novel Volume SS2
She was one of the Sisters sent to the Gemstone Mining research organizations to destroy the facilities and rescue the Gemstone there. On the Second Friday of October she was in Antarctica at the Extraterrestrial Chaos Observatory. During her periodic progresses report she had met with some type of resistance.

Abilities
Like all the Sisters, her ability is known as Radio Noise (欠陥電気 (レディオノイズ) ), a subset of the Electromaster (電撃使い（エレクトロマスター）) ability. As an esper around level 2-3, the ability allows her to generate 1/20000 of Misaka Mikoto's power, the Railgun, so her ability has a maximum output of only 50000 volts. However, unique to this ability is the Sisters having a form of telepathy that is formed from the similar brainwave patterns, forming a brainwave network. This collection of Sisters connected linked to each other is called the Misaka Network, this also allows her to share memories and experiences with the other clones.

Other abilities

 * Military training: Included in the information that was transferred with the Testament machines, like the other Sisters, she is proficient in combat methods such as the aforementioned use of specific weapons, can track targets, and shake off pursuers.
