Professor Amamori is the head scientist at the Tsukuba Observatory. He is Hajime's uncle, though Hajime's father is his younger brother in the TV series and his older brother in the film. He became Hajime's guardian after his parents were both killed in an explosion. Amamori discovered the 10th planet, La-Metal, and determined it would collide with the Earth. At first, he had plenty of hair, but the discovery caused him to begin losing hair (though in the TV series, he keeps all his hair).
