Kodama was the boy chosen to pilot Zearth during the third battle with the robot, Cancer. He was a relatively quiet boy who liked to keep to himself. His father was a wary individual who ran a civilian contracting company. Kodama's two gifted older brothers hate their father and try to go towards a different path, however Kodama looked up to him and his status as a "chosen" man. He even wore Kokopelli's glasses to seem smarter like his father. Being raised by his father seems to have warped Kodama's sense of ethics and morality to the point where he enjoys to take shots at stray cats with a pellet gun.
