He may start as the same timid character from Evangelion, but the challenges in Berserk force him to become stronger and more confident. This transformation is what makes many of these fanfics appealing.

Also, a story where Shinji forms a secret club with some of the other Nerv members to have a bit of normalcy in their crazy lives could be really interesting.
