Sabian

From RPGwiki

Sabian was a crazy, a warrior who had received implants in his brain to tap into his mind and body’s unused resources. The downside was the strain the implants caused on the mind, causing increasing mental problems for him. In Sabian’s case the implants caused the creation of several multiple personalities. During the fight with the demon ship he manifested the Ripper, perhaps a brutal personality combining all his worst traits. It wasn't enough as he was dragged down kicking and screaming by the demons.
