Misaka Worst

Misaka Worst (番外個体, Bangai Kotai, lit. "extra individual") is the newest lineup of Misaka Clones introduced in Toaru Majutsu no Index.

Background
Little information is available for these new clones, but it is certain that they are created for a different purpose than their predecessors. This series of clones are made from the "Third Production Plan", which began after Last Order was taken by Accelerator. They are at Level 4, stronger than the normal Level 2 Sisters and the Level 3 Last Order. These clones can fire railguns, though their railgun can only just go past the speed of sound, unlike Mikoto who can make it go past three times the speed of sound. The colour of their lightning is purple, unlike Mikoto's which is blue; also, Misaka Worst uses metal stakes instead of coins as bullets.

One of them is to replace Last Order as the administrator of the Misaka Network, to bring it into a stage above what they are now in order to further Aleister's plan.

Appearance
Compared to the first 20,001 clones of Misaka Mikoto (all clones except Full-Tuning), Misaka Worst's physical form is a high school student version of the Level 5 Electromaster; it is also pointed out that they are 2-3 centimeters taller than the original.

Their physical features also differ to the first batch of Sisters; they have dark circles around their eyes and has orange pupils, compared to the gray pupils of the 20000 Misaka Clones and to the original's brown pupils. They no longer wear a similar hairpin as the first batch, and they do not wear Tokiwadai Middle School's uniform; instead, they wear a full-body suit. To prevent this series of clones being controlled by Last Order, all of the clones are cut up and have many metal parts embedded in them, which according to the Misaka Worst clone that fought Accelerator was painful beyond belief.

In New Testament, said Misaka Worst wears a pink and white aodai given to her by Yoshikawa Kikyou.

Personality
As for their personality, though they have the same appearance as Mikoto, their personality was programmed to be similar to Mugino's. In the case of Misaka Worst, the Accelerator slightly reprogrammed her personality to prevent her from commiting suicide after she failed to eliminate Accelerator.

Misaka Worst is supposed to be the outlet of the Misaka Network's negative feelings, she was designed as such in order to have an extra effect when faced in battle against the Accelerator; as such she can grasp most of the bad things that the other sister's are feeling and if the feeling is too strong it might even take over her own actions even though she can normally control interference from the Misaka network, for example in one opportunity Last Order experienced such strong jealousy towards the Accelerator's freedom of going out freely that Misaka Worst couldn't cope with the feeling and urged the Accelerator to let her tag along even though she had no personal desire to go with him. Due to the effect of those negative feelings Misaka Worst is also a little bit of a prankster and tends to either tease or cause discomfort to others much to the chargin of the Accelerator who is usually in the wrong end of Worst's outburst, he also noted that she lacks even more common sense then he does.

Fiamma of the Right and World War III Arc
October 30th.

As of Volume 20, when the Accelerator is in Russia, she has an encounter with him. At this point it is disclosed that Crowley's intends to make a new network with the new line of clones, and eliminate Last Order who has now become obsolete. Despite being far more powerful than the clone, the Accelerator is at a disadvantage since he cannot bring himself to hurt another clone after the Level 6 experiment, and sustains minor injuries. Misaka WORST then proceeds to taunt and mentally traumatize him, telling him about the Sisters' hatred of him, and how Last Order's emotions for him are false. She ultimately forces Accelerator to choose between protecting Last Order or upholding his vow to never hurt another Misaka clone.

This causes Accelerator to have a mental breakdown, losing all reason when he awakens, and goes berserk. He proceeds to beat Misaka WORST into the ground, and tear her flesh apart, becoming even more cruel and barbaric than his old personality from the days of the experiment. Despite having lost all faith in humanity, he still saves her when she attempts suicide as this was his way of showing the scientists who doubted him, that he does have the capacity to save people (alternatively, he only did it to annoy the ones who thought up this plan, telling them they've failed in their calculations). He then continues his rampage in front of an injured Misaka WORST, which she notes that being around him and seeing this state causes her to feel a lot of fear and regret for pushing him too far.

After Volume 20 the now injured Misaka Worst travel along the Accelerator, at which point the Accelerator will entrust her with Last Order safety whenever he is too busy fighting, Misaka Worst will eventually prove pivotal to Last Order's recovery, as she supplies the Accelerator with information about Index song from within the Misaka Network, which the former uses to heal Last Order for good.

After the events of volume 22, she lives a peaceful life next to the Accelerator, Last Order, Yoshikawa Kikyou and Yomikawa Aiho.
