**Misaka Mikoto** *(御坂 美琴 Misaka Mikoto?)* *(born May 2)* is one of the main heroines in Toaru Majutsu no Index and the main protagonist of Toaru Kagaku no Railgun. Introduced in the first volume of the light novels, her role in the story was later expanded in the third volume as well as the release of the Toaru Kagaku no Railgun manga, making her the main heroine of the science side and the second main heroine of the series.

She is the third ranked Level 5 esper in Academy City, and has been nicknamed Railgun due to her signature move. Kamijou Touma coined the nickname **Biri-Biri** *(ビリビリ?)* (a Japanese onomatopoeia imitating the sound of electricity), while in the English dub she is referred to as "Bug Zapper" (or more usually, simply "Zapper"), and whenever the two meet, he usually calls her that, even after his amnesia.

## Background

Mikoto is the daughter of Misaka Tabigake and Misaka Misuzu. She entered Academy City in elementary age, and distinguished herself as a child prodigy, initially starting out as a Level 1 and climbing her way up to a Level 5 esper. This made her a perfect candidate for the Sisters Project, which held the intent of cloning her for military use. Mikoto willingly gave a DNA sample to the researchers of the project after being told that it would help people who suffer from muscular dystrophy, a fatal disease.

She later enrolls in Tokiwadai Middle School at the age of 12, and soon becomes a Level 5. In her first year, she lost a 10,000 yen bill due to A Certain Vending Machine, probably explaining her propensity for kicking it. In one fateful event, she saved her future friend Shirai Kuroko from a robber by using her 'Railgun' ability. Kuroko eventually enrolled at Tokiwadai as well and gained great affection for Mikoto. Mikoto later became roommates with Kuroko in Room 208 - despite Kuroko being her junior - after Kuroko 'legally' removes Mikoto's previous roommate who was supposedly ill-natured towards Mikoto. Being a Level 5 esper as well as a student with consistently high grades, Mikoto is known as Tokiwadai's Ace.

## Personality & Character

To most people, she is considered a 'proper lady' (referred as ojou-sama or お嬢様). In reality, she's short-tempered, prideful, and has an improper attitude with some slight violent boyish tendencies (or masculine since she wears boxers and an undershirt) and insecurities, a fact few people know of. Despite this, she is friendly and easygoing, and Saten Ruiko and Uiharu Kazari comment on how they are shocked to find that, compared to other Level 5's, she doesn't look down on lower-level espers at all. This probably is because she was originally a level 1 esper, and became a Level 5 esper through hard work.

She often shows an incredibly immature and selfish side and displays heavy tsundere tendencies when her crush, Touma, insults her. To add to this childishness, she is inclined towards cute things, most specifically, Gekota and Kill Bear merchandise. She likes frog merchandise, but only if it features Gekota. When she realizes that a stuffed animal another person is carrying is just a regular frog, she immediately loses all of her interest in the stuffed animal. She has a very irrational and unexplained fear of bugs, as shown in episode 6 of Toaru Kagaku no Railgun. She can also be slightly hypocritical at times, getting angry at Touma for not calling her by her name despite never once calling him by his. While generally amicable and humble, Misaka is highly individualistic. She often prefers to be solitary and dislikes the idea of being restricted by rules and duties such as those of Judgement and Anti-Skill. She wishes to avoid endangering other people and relies on her powers to try to solve problems on her own, frequently despite her better judgment.

She has a keen sense of justice, demonstrated by her frequent involvement in the crime-fighting body, Judgment, and her resolve is unshakable. This is shown when she was willing to lose in a fight against Accelerator on the first move, just to prove the Sisters Project was wrong and save the remaining 9969 sisters (Tree Diagram predicted that she would die in the 185th move). She secretly likes cute things, especially Gekota (a popular frog mascot), and is easily embarrassed. She often goes to Green Mart to read manga for free in her spare time on Mondays and Wednesdays and goes to the bookstore on the 10th of each month[3]. She's also good at playing the violin and teaches Uiharu Kazari how to play in Volume 12 of the Light Novel. Furthermore, according to Shirai Kuroko, Mikoto naturally acts as a leader and becomes the center of attention by everyone, yet she cannot mingle with those people regardless of being the center. She states that Mikoto is at the top and defeats her enemies, but she cannot avoid making more enemies at the same time. Moreover, she states that the most important to Onee-sama is someone she can feel on the same level as her.

Mikoto is known for being very intelligent, only natural as she is in Tokiwadai Middle School, a school that is meant to create world-leading talents and thus deals with a very advanced curriculum. Furthermore, she has been shown to be capable of solving problems intended for Kamijou Touma who courses a school rank higher than her, though it should be noted that Kamijou's school doesn't pursue the same academic excellence that Tokiwadai does.

It was shown that Mikoto had intended to take the trial enrollment into Touma's school during the Ichihanaran Festival, which further showed her interest in Touma, though this came to naught as she was interrupted by Shokuhou Misaki.

As of December of the current year, following the encounter with the High Priest and a glimpse at what Touma had been facing, Mikoto's pride has been considerably damaged, seeing how far behind she was and feeling she was nothing but a burden to him. At the same time, she is desperate to catch up with Touma and be able to stand on the same stage as him so she could tell him her feelings.

## Powers & Abilities

### The Railgun

Mikoto's power is known as the Railgun (超電磁砲 Chō-Denjihō (Rērugan)?, lit. "Super Electromagnetic Cannon").[2] She chose the ability name herself, naming it after her famous finishing move.[3] Her ability belongs to a type of esper powers known as Electromaster (電撃使い Dengeki Tsukai (Erekutoro Masutā)?, lit. "Electricity User"): those who can generate and manipulate electricity.

Mikoto is the most powerful Electromaster in Academy City. Her maximum output is known to be 1 billion volts. She has also demonstrated enough skill and battle knowledge to fight head-on with powerful beings such as a Saint like Brunhild Eiktobel.

* Mikoto can fire metal objects at three times the speed of sound by forming parallel currents on both sides of her arm with her electricity. Her Railgun has a muzzle velocity of 1030 m/s (2307.2 mph), and can be fired at a rate of 8 shots per minute. She has hinted she can fire multiple coins at once creating a Rail-Shotgun, however this has never been seen. She primarily uses arcade coins as her projectiles for portability, limiting her normal range to 50 meters.
	+ With some help from Misaki's ability to manipulate liquids and the power of the Anti-Art Attachment, Mikoto was able to produce a version of her Railgun that no longer has a speed limit nor distance limit. In the novel, it was stated to have an "endlessly frightening destructive power" which later on mercilessly destroyed the Windowless Building.
* Mikoto has the ability to generate a "spear of lightning" originating from her forehead.
* **Powerful Electromagnetic Pulse**: Mikoto can create magnetic pulses that target the organs.
* **Lightning Strike**: Mikoto can call down real lightning using her ability regardless of the season. This attack was shown to be powerful enough to cause a city-wide blackout. She is also capable of calling down massive thunderclouds with multiple lightning strikes occurring from within.
* **Electromagnetism**: Mikoto can use electromagnetism to attract and repel metallic materials and use it to her advantage. Examples include creating a make-shift shield out of scrap metal, walking on walls and ceilings, as well as attracting iron particles in the ground around her. She can also use electromagnetism to interfere with radar, and radar-based weapons liked guided missiles. She can use it to manipulate metal tools or weapons held by the enemy, interfering or completely stopping their attacks. She can also magnetize them so that all sorts of iron objects will attach to them, increasing their weight. Her power and control over electromagnetism is enough to be able to temporarily support several uprooted and pilled up buildings while preventing the structures and their occupants from being crushed. She is also capable of manipulating electromagnetic waves, such as microwaves, and diverting them.
* **Iron Sand Manipulation:** Mikoto can use electromagnetism to manipulate iron sand which vibrates ten times stronger than a chainsaw. She can use it to create long hands or small "tornadoes" around an enemy to attack them, to create a large iron sand wave much like a tsunami, to create several hundred drills that have electricity running through them to pierce the enemy, she can spread it around the ground to follow an enemy that moves at supersonic speeds or use it to create a storm of killer needles that surround the opponent for a 360 degree attack.
	+ Using her magnetic powers, Mikoto can form a "whip sword" by gathering iron sand, manipulating it into a sword that she can lengthen into a whip at will. By making the sand particles of the blade vibrate, she can dramatically increase the weapon's cutting power into something resembling that of a chainsaw. She can create multiple iron sand whips to allow her to attack from several directions at the same time, described as being similar to an octopus' tentacles or a spider's legs.
	+ **Iron Sand Puppet**: During her battle with Kuriba Ryouko's doppelganger, Mikoto used her ability to create a gigantic puppet out of dust and iron sand to match the doppelganger's own gigantic puppet. This puppet is somewhat fragile due to the small parts making up its body, but it can regenerate and change forms. Additionally, the iron sand can infiltrate wounds inflicted to its enemy and cut it from within. The vibrating iron sand particles inside the puppet rub together and build up electricity, making the puppet dangerous to touch and can be used to fire an iron sand bullet, which penetrated the armor of the doppelganger's giant puppet and caused massive damage to it.
* **Plasma Creation:** Mikoto is able to create plasma to distract the enemy's eyes by ionizing empty cans.
* **Electric Cage:** Mikoto can combine her electricity and iron sand to create a large cage to trap an enemy. First, Mikoto creates several hundred iron sand balls around her, which spread around the area before dividing into smaller spinning balls. The balls then start emitting bluish sparks as Mikoto uses them to conduct electricity to cover the gaps between the iron sand balls, forming the cage. Mikoto can freely control the size and shape of this cage, and can repair it and reform it in case it's damaged by controlling iron sand.
* **Cracking/Hacking**: Using her electric powers she can hack any electronic device and bypass normal electronic security measures with ease. She can decode the electronic flow of information, like to steal the information from a credit card's magnetic strip, as well as directly process a computer's information in binary. This skill also enables her to perform acts such as erasing herself from security footage in real time or taking control of Academy City's roving security robots. Furthermore, it is revealed in Volume 7 of New Testament that she can even use her power to take control of cars.
* **Unique Sensory Perception of Electric-type Espers**: As an electromaster, Mikoto is of course able to sense electric, magnetic, and electromagnetic phenomena. She is, however, able to follow the electric and magnetic field lines using her eyes, something that normal electromasters are unable to do with their limited power.
* **Flight**: Using formulas similar to those she is using for her Iron Sand sword, Mikoto can fly if she is surrounded by a large amount of atomized water vapor. She manipulated the water vapor forming it into wings using the static electricity from interactions between particles. By using her electric power to induce electrolysis on a large body of water such as the ocean, she can obtain enough hydrogen and oxygen to use as fuel.
* **Telepathic Immunity**: Mikoto has been shown to be immune to the effects of telepathic manipulation due to the electromagnetic barrier created by her AIM Diffusion Field.
* **Radar Sense**: Mikoto can sense and release electromagnetic waves around her to enable her to see the image of the room three-dimensionally without the use of her sight, giving her no blind spots.
* **Control of nerves and muscles:** Perhaps a reference to her powers being applied to help those with muscular dystrophy. Mikoto is shown to be able to use her powers to take control of her muscles and nerves when they have been rendered ineffective through the use of drugs. The cost of this however is that she requires to constantly use her powers on her body, making her a walking stun gun.

### Anti-Art Attachment

Main article: Anti-Art Attachment
Following her initial encounter with the Anti-Art Attachment, Mikoto had a modified version of the powered suit created for her own use. This Anti-Art Attachment possesses most of the armaments and firepower used by the original version. Mikoto has attempted to reconstruct the original's 'black box,' but apparently hasn't been able to recreate it. She has been experiencing nose bleeds since she began to use the A.A.A.

### Exterior-forced Misaka Network connection

Main article: Level 6 Shift attempt on Misaka Mikoto
During the Daihaseisai, Kihara Gensei takes over Exterior, shatters the defenses Shokuhou Misaki had set-up for the Sisters against electrical viruses, and infects them with a virus that forcibly connects the Misaka Network with Mikoto. Here, Mikoto receives a tremendous amount of power, and her appearance changes as she continues to grow in power towards Level 6. Her consciousness is also suppressed due to the external influence. According to Gensei, at 53% of the way, her mind would be distorted into that of something from a different dimension. At 100% her mind and body would be destroyed as they exceed their limits, taking Academy City with her. According to Misaki, Touma’s presence (likely referring to his Imagine Breaker) restrains her growth, while Gensei says that Imagine Breaker acting as a stimulus and Sogiita Gunha with his non-standard power would cause something extraordinary to occur. It is likely the transformations Mikoto goes through is affected by Touma and Gunha’s presence.

During the course of Mikoto being forcibly used as a subject to become a Level 6, she transforms a few times, becoming more powerful each time:

* **Initial form:** Mikoto’s initial form upon engulfing the power of the Misaka Network, Mikoto’s appearance changes. Her hair becomes swept back, with a few fringes gathering together to form two horn-like appearances on her head. The sclera of her eyes also darken. The most obvious change, however, is the appearance of two ribbon-like objects with diamond shaped objects attached to them that hug around Mikoto’s arms. It is likely a mass of compressed energy, as Gunha would later be hit by similar things later.
	+ Described by Gensei as 2% up along the path of a Level 6, already it is powerful enough to create a large electric attack that completely engulfs the already tall Windowless Building and a large area that surrounds the building, though predictably the Windowless Building is unscathed. This attack is referenced as the largest scale lightning strike ever recorded. Other features of her power include creating smaller strikes that resemble beams of energy, manipulating several chunks of metal and iron sand, and seemingly traveling through the strike of her electricity - literally “riding the lightning.”
* **First transformation:** Mikoto transforms even further, and her appearance changes drastically. Her horns begin transforming and hardening, forming an onion-dome shaped structure on her head, at the widest part sits something that looks like an eye. Something revolves around the tapering structure, and at the top sits a sphere, like a miniature Saturn. As for the rest of Mikoto's body, the ribbons from before have begun connecting to her body itself. Her hands and feet have tapered as well and are connected with the ribbons.
	+ Under this form, Mikoto can use those ribbon-like things to attack, which Gunha describes as a compressed mass of energy after hit by it. It is apparently solid enough as Gunha is also pinned down by ribbon-like objects much later. Likely, all of the powers that Mikoto displayed in her previous form is retained here and in a stronger version.
* **Second transformation:** What Gensei describes as the **Opening Stage**, this is her final form just before she is turned back to normal. Her hair is swept back, and a complex halo appears over her head: a circle with four points on each direction, and floating at the center of it is something of rectangular shaped, tapering at both ends, with the bottom part being shorter. All of her clothes disappear. Her head down to the area of her collarbones are colored black and dotted by something resembling stars; it’s as if it was outer space or the night sky. Her hands and feet have disappeared. Her hand becoming claw-like with ribbon like protrusions, with her legs even more abstract-looking, connecting through the ribbons.
	+ After Kouzaku Mitori seemingly defeats Kuroko, she uses her Mental Out power from Exterior and orders Mikoto to destroy the Windowless Building again. Then the ground where Mikoto is floating on turns black. Mikoto holds out her hand where she forms a large black sphere of energy. Gunha would later describe this as something from another world that cannot be understood. Mikoto would later describe it as something that she called in by her desire to crush and eliminate the parts of Academy City she doesn’t like.

### Other Skills

Other than her esper powers, Mikoto is in top form physically and mentally. She has proven to be very knowledgeable when it comes to electronic devices, being able to guide others about them over a phone call.
