Shahin was shaped by many popular games. His backstory is that he was a test subject, and eventually when he became headless, he underwent surgery to provide him with a robotic head. He is programmed via the access panel that is on his neck, and this is what keeps him alive - if anyone should tamper with it, his personality can change, or it could cause his death (read: freezing, rather than actual death, as his robotic functions keep him in a perpetual state of life).

His personality can be summed up as anger, bloodthirst and aggression. He is not the sort of individual to take arguments well, and he is well equipped to fight - and in fact, has fought in several battles/wars in the past. There have been plans to try and mate him in order to try and enable the genome to continue, for after many years a successful attempt at forming a gene to represent his robotic features was enabled.
