Dr. Kai Narasu

""Because of this, the inescapable conclusion one must inevitably come to is that this so called "hedgehog" is, in reality, a machine.""

- Dr. Narasu in his brief anime appearance.

Dr. Kai Narasu is a minor antagonist made major in the "Sonic X" comics. He was a scientist at Area 99 (and/or a biology-related expert in the anime) until he was fired for claiming that Sonic was a robot, which misled his faculty's information. His voice actor was not credited in the anime.
