Tereus is the clone of Briareos, who bears the exact likeness of him in his pre-cyborg state. A member of the new fourth generation of Bioroids, he still is marked by highly-regulated emotions, but has the ability and mental capacity to engage in combat and kill, but only in the interest of law enforcement and lifesaving ventures. Unlike humans, he can't be provoked into violence and would never let anger affect his judgement.
