The father of Amuro Ray and former husband of Kamaria Ray. He was an engineer working with the Earth Federation on the V Project, a military armaments plan to create the Federation's first prototype Mobile Suits. Born on Earth Tem took Amuro to Side 7 with him, leaving Kamaria behind of her own free will.
After surviving the accident on Side 7 where he was sucked into outer space, presumably to his death, Tem was taken to the neutral colony of Side 6. The extended period of time he spent in space however left him with oxygen deprivation, leaving him delusional with mood swings, with his scientific mind ruined.
