To Aru Majutsu no Index/Characters/Sisters

The Radio Noise project was originally devised to mass produce Level 5 esper clones of Mikoto Misaka, but only managed to produce Level 2 or 3 espers. It was later retooled in the Level 6 shift project, which involved creating 20000 clones in order to force Accelerator to attain Level 6. After the project was stopped by, several clones are still around after the project. This page details the most prominent ones.

Mikoto Misaka

 * Shock and Awe
 * Third Person Person
 * Younger Than They Look: Comes with accelerated growth.

Misaka 9982: It's horrible.

[...]

"Researcher: The people [in the outside world] are packed like sardines, though.

 * Blush Sticker
 * Cheerful Child / Genki Girl: Unlike the other 20,000 Sister clones, she's quite capable of expressing emotions and is quite a cheerful girl.

 * Annoying Laugh
 * Anti-Hero: Started out as Type V-IV, but has now shifted towards Type III.
 * Ax Crazy: Justified. She was literally designed to be this by genetic manipulation; as she runs off the negative emotions in the MISAKA Network and had Accelerator's old thought patterns forced into her.
 * Bad Powers, Bad People:
 * Badass: From the short amount of time she's been in the story, she's shown to be one.
 * Worst has more in NT, in volume 2, she pulls off a One-Man Army by

 * Boobs of Steel
 * Byronic Hero

Misaka Mikoto: Now you’ve said it!!"


 * Break the Haughty: Administers this to Umidori so much that she makes her cry.

 * Dark Action Girl
 * Dark Magical Girl
 * The Dark Side: She often states that she lives for this.

 * Seems to be able to keep up with Shiage.
 * Heel Face Turn: Teams up with after
 * Has Two Mommies:
 * Hellish Pupils

 * Jerkass
 * Knife Nut: In NT, when Accelerator told her to use it against the FRESHMEN, she told him she already did. Knowing Worst, who knows what she could done to them?
 * Laser Guided Tykebomb:

Accelerator: Who are you trying to please by doing that? Yourself?

Misaka Worst: Well, there is that. If it would be devastating to your relationship with Last Order, Misaka will let you touch her tits and ass, but doing it now would seem rather pointless."

 * They Would Cut You Up: Poor WORST.
 * Troll: Oh so very, very much.
 * Tsundere: She has show slight signs of this towards Accelerator because of the aforementioned use of Enemy Without.
