Shinji Ikari in the context of Rebuild of Evangelion

Neon Genesis Evangelion (Japanese: 新世紀エヴァンゲリオン, Hepburn: Shinseiki Evangerion; lit. 'New Century Evangelion' in Japanese and lit. 'New Beginning Gospel' in Greek), also known as simply Evangelion or Eva, is a Japanese anime television series produced by Gainax and Tatsunoko Production, and directed by Hideaki Anno. It was broadcast on TV Tokyo and its affiliates from October 1995 to March 1996. The story, set in 2015, fifteen years after a worldwide cataclysm in the futuristic fortified city of Tokyo-3, follows Shinji Ikari, a teenage boy who is recruited by his father Gendo Ikari to the mysterious organization Nerv. Shinji is tasked to pilot an Evangelion, a giant biomechanical mecha, to fight and destroy beings known as Angels.

The series has been described as a deconstruction of the mecha genre; it delves into the experiences, emotions, and mental health of the Evangelion pilots and Nerv members as they are called upon to understand the ultimate cause of events and the motives behind human action. The series features archetypal imagery derived from Shinto cosmology and mystical Judeo-Christian religions and traditions, including Midrashic tales and Kabbalah. The psychoanalytic accounts of human behavior put forward by Sigmund Freud and Carl Jung are also prominently featured.

Gendo Ikari (Japanese: 碇 ゲンドウ, Hepburn: Ikari Gendō) is a fictional character from the Neon Genesis Evangelion franchise, created by Gainax. In the original anime series with the same name, Gendo is the supreme commander of the special agency Nerv, which is dedicated to the study and annihilation of Angels, a series of mysterious enemies of humans. Gendo is grief-stricken by the sudden death of his wife Yui, and abandons his son Shinji Ikari to devote himself to a plan named Human Instrumentality Project. Years later, Gendo asks Shinji to pilot a giant mecha named Evangelion; his pragmatic, cold, and calculating attitude leads him to use any means to achieve his personal goals. He also appears in the franchise's animated feature films and related media, video games, the original net animation Petit Eva: Evangelion@School, the Rebuild of Evangelion films, and the manga adaptation by Yoshiyuki Sadamoto.

The character, who was originally conceived as a modern version of Victor Frankenstein, is inspired by the personal experiences of the series' production staff, reflecting the absent, emotionally detached Japanese father figure. Neon Genesis Evangelion director Hideaki Anno's abusive father particularly influenced Gendo; the director also took inspiration from psychoanalytic concepts, especially the Freudian Oedipus complex, for his development.
