Shinji Ikari is the protagonist of Neon Genesis Evangelion, and the pilot of Evangelion Unit 01. His father, Gendo Ikari is the leader of Nerv, the organization dedicated to the eradication of the Angels. His mother, Yui Ikari mysterously died during unit 01's activation experiment.
In contrast to having a strong, confident character as the protagonist, Shinji is a rather weak, unsteady character. In the beginning of the series, Shinji is friendless, simply does what people order him to do, and apologises for everything. However, he gradually becomes more confident, expressing himself more, and developing friendships.
