Ikari Gendou
Chief Commander at NERV
Analysis:
Gendou is a dark and cold character. As Chief Commander he is rational and efficient, but as father of Shinji he utterly failed. For him Shinji is nothing more than a tool which he uses when needed and throws away afterwards. Oddly enough he developed a father/daughter relationship to Rei, who is the only person he treats like a real human. He seems to be working for his own agenda which remains a mystery.
