However, Mikoto is powerless against Accelerator due to his abilities. Later it is revealed that 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.Īccelerator first appears in Railgun, where during another session of brutally killing a Misaka clone, he meets an enraged Misaka Mikoto who tries to get revenge on him after she witnesses him killing Misaka 9982. By the beginning of the Sisters Arc, Accelerator has already killed the first 10,030 Misaka Clones and during the course of the arc, kills clone 10,031 before the experiment is ultimately stopped. He willingly joins the experiment to gain a reputation as the most powerful and feared esper so that no one would be foolish enough to challenge him ever again. 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. Accelerator’s ability made him the subject of an experiment attempting to create the first Level 6 esper according to the city’s best supercomputer, Tree Diagram, this feat could only be achieved by killing Misaka Mikoto, the ‘Railgun’, 128 times.
