.PERSONALITY.
Due to the potential of his ability, Accelerator has been targeted by assassins and researchers throughout his life. As a result, he believes only in power and trusts no one. While fighting, he invokes fear and has a sadistic tone. He willingly joins the SISTER experiment to gain a reputation as the most powerful and feared psychic so that no one would dare be foolish enough to challenge him and won't hesitate to kill any who get in his way. The Sisters' memories of his behavior during the experiment may suggest that he is, in a way, a pacifist; because his power won't disappear, the only way he sees an end to the fighting is to be so strong and sadistic that no one would dare to raise a finger against him. He even seems to attempt to frighten the Sisters out of fighting or otherwise encourage them to refuse their battles. After meeting Last Order, he strives to protect her (although he states he does not like her company, he tolerates her). He saved her from Amai Ao's plot and from being pursued from the Hound Dogs. He treats Index in a similar fashion, such as when he buys her lunch while searching for Last Order and by protecting her from the Hound Dogs. he has mellowed out to the point that he actually lectures a child in order to prevent him from getting himself killed after a hostage situation. His attitude towards Touma was hinted , when it is shown that he both idolizes and is slightly jealous of Touma's heroic personality, and is outright shown when he and Touma finally come to blows. By comparison according to Heaven Canceler, Touma and Accelerator are very similar, but their methods are like opposite sides of a coin; Touma is able to protect his loved ones without killing and is able to stand by their side, while Accelerator protects his loved ones through violent methods and even admits that he is unable to stand by Last Order and Yomikawa's side. Deep down, he is someone that aches for the light, as shown when Yomikawa was able to walk up to him and slowly take a gun from his hands before he tried to finish off Kakine after their fight, and later when he refused to hurt a Misaka WORST clone and tried to heal her wounds after she tried to kill herself. Aiwass has also commented on the differences between Touma and Accelerator – stating how Accelerator craves for the wholesomeness of being a 'hero' like Touma, even to the point that he declared himself evil because he believes he cannot reach that level. He is someone that tries hard to redeem himself. Accelerator was shown to often underestimate his enemies earlier in the series, which led to his loss against Touma. However, after nearly being killed by Kihara Amata and fighting Komaba Ritoku, he no longer underestimates his enemies. This fact is noted by one of the terrorists in Hula Hoop as possibly being the most terrifying thing about him: he always uses exactly how much force he needs to in order to defeat his enemy: no more and no less. If he ever underestimated his enemies, it would have given them an opening they could have exploited, but since he didn't, he simply wiped them out. After-word the author states that what Accelerator wants most is not a lover but a family, and states Last Order is like his child he has to take care of. Misaka Worst said half-jokingly she wants the same fatherly treatment he gives to the other Misaka clones. Accelerator's ability made him the subject of an experiment attempting to create the first Level 6 psychic; according to the city's best supercomputer, Tree Diagram, this feat could only be achieved by killing Misaka Mikoto, the 'Railgun', 128 times. However, because it was impossible to create 128 of these 'railguns', due to the 'Level 5 Mass Production Plan' only being capable of producing a sub-standard clone of Mikoto at a power of Level 2-3, a substitute plan was arranged where Accelerator would have to kill 20,000 Misaka clones in a variety of methods. He willingly joins the experiment to gain a reputation as the most powerful and feared psychic so that no one would be foolish enough to challenge him ever again. By the beginning of the Sisters Arc (index), Accelerator has already killed the first 10030 Misaka Clones and during the course of the arc, kills clone 10031 before the experiment is ultimately stopped. Later it is revealed he originally wanted this reputation simply so that no one would ever get hurt trying to attack him, resulting in their own destruction, though as he went deeper into Academy City's dark side his goals slowly became more and more twisted.
