NXE is a crossover fanfiction by Eyrie Productions Unlimited. The central fanfiction is Neon Genesis Evanglion, but other crossovers include the X-COM and Tomb Raider video games and the In Nomine RPG (which plays a huge role in the cosmology of NXE) as well as numerous cameos. NXE was published in three 'seasons' of nine chapters each and the finale Apothesis Now.
The core concept of NXE relocates NERV from Tokyo to the fictional Worcester-3 and shuffles the main cast significantly. Most specifically, Shinji Ikari's participation is extremely belated, as witnessing Rei's disasterous first synchronisation test leads to him leaving Worcester before the beginning of the story. The role of protagonist is intially taken by Derek 'DJ' Croft, an original character who proved somewhat controversial with fans concerned that he was a Mary Sue. The piloting roster is filled out by Jonathon Ellison, an X-COM raised child soldier, Rei Ayanami and Asuka Soryu-Langley.
