Dr. Naoko Akagi was the chief scientist of Gehirn, NERV's predecessor organization, and designer of the Magi supercomputers, which she copied her own thought patterns onto. Naoko felt that the Magi represented the three aspects of her personality: herself as a scientist (Melchior-1), herself as a mother (Balthasar-2), and herself as a woman (Casper-3). She was also heavily involved in the creation of the Evangelion Project with Gendo Ikari. She is the mother of Ritsuko Akagi by an unknown father.
