NERV is the paramilitary agency in the Neon Genesis Evangelion universe formed to combat the ‘Angels’ after the Second Impact. It is responsible for the creation of the Evangelions. Although NERV is under the control of the United Nations, it is an independent organization. The United Nations is the source of NERV’s funding, income, and equipment for its operations. In the Rebuild of Evangelion movies, NERV is bound by the Vatican City Treaty, which restricts the number of operational Evangelions a single country can control at any one time.
Headed by Commander Gendo Ikari, Nerv’s origins lie in the research organization known as Gehirn, which was renamed and reorganized into “Nerv” in 2010 after its headquarters at Tokyo-3 and the Magi supercomputers were completed. Unlike Gehirn, whose existence was officially a secret (with the UN Artificial Evolution Laboratory serving as a front), Nerv is semi-public. Secretly, Nerv is backed by the mysterious organization Seele — a power cabal covertly controlling the United Nations. Nerv and Seele’s ultimate goal is to eliminate the Angels so that they can use the Eva Series to carry out their plan to initiate Third Impact and elevate humanity to the next stage of evolution: the Human Instrumentality Project.
The NERV logo is seen on uniforms, identification cards and flags throughout the Evangelion series (including it’s remake, and the movies).
