Misaka 10777

Misaka 10777 (ミサカ10777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 organization in Russia.

Appearance
She looks the same as Mikoto, although for emphasis, her eyes are drawn in a different way. Like all Sisters, Misaka 10777 wears goggles and blue-striped panties. However, instead of Tokiwadai Middle School's uniform, she is seen wearing a Russian military uniform equipped with a Kalashnikov rifle.

Personality
She has the same personality as most clones, with emotions that have been suppressed as they weren't beneficial to the experiment. After interactions with Mikoto and their experiences in World War III, she openly expresses her sadness at the level of difference after witnessing the original disable nukes and defeating 2000 armed units.

Similar to most of the other clones, she seems to have feelings for Kamijou Touma as shown when she displays envy towards how much closer Misaka 10032 and her original, Misaka Mikoto, are to Touma than her.

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.

Woarld War III Arc
She meets Mikoto for the first time when she drops into Russia after the supersonic plane she was in, was destroyed. 10777 stated that after the evacuation of the organization supported by Academy City was complete she stated that she was spending the rest of the time to spend on her private business.

Later, she and Mikoto work to disable all the nukes from being detonated and defeating forces from either Russia or Academy city to prevent any casualities. After that the two take a VTOL to the Star of Bethlehem in an attempt to rescue Kamijou Touma.

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 previously mentioned use of specific weapons, being able to trace targets and being able to shake off pursuers.

Equipment

 * Weapons & Gear: She wears a special set of goggles that enables her to see electron beams and magnetic field lines, because like all the Sisters she can't perceive without aid. Being transferred to Russia for body adjustments, she uses an AK-47 rifle, and is capable using any weapon the other Sisters have used.

Design evolution
Misaka 10777 retains her looks like much of her fellow cloned sisters in order to differentiate her from Misaka Mikoto. Currently appearing in a single arc, Misaka 10777's design remains static throughout the series. According to Haimura, he wanted to put a Russian hat on Misaka 10777's design.
