貞本義行
Gendo's last names (Rokubungi and Ikari) mean "sextant" and "anchor" in Japanese, respectively; his first name was taken from another anime project prior to "Evangelion" that was aborted. Yoshiyuki Sadamoto has admitted inspiration from the British television show " UFO" for the design of Gendo's uniform, specifically that worn by Commander Edward Straker (with Fuyutsuki's based on Col. Alec E. Freeman).
