Nebuchadnezzar is sort of a mix between Sonic.EXE, Xenophanes, and Lord X. His personality I would like to describe is that of a very intelligent, very patient, yet a very insane mature adult. He can wait for years and years on end, subtly tormenting his victims no matter how fast or how slow he does it. So it is sort of like him playing house, or playing pretend with his victims until they find out that who they have been talking to is not who they seem at all.
