Human. Dr. Alto Clef–one and only–Director of Department of Training and Development known for terminations of dangerous reality benders. Clef is a man of contradictions, he's a hard to read liar with lack restraint or social etiquette, though this is usually a show put on mostly for his own amusement, jokes are often offensive and his insults can border on abusive. He's confident to a fault. He's a reality bender, loyal to the SCP Foundation, a former GOC agent "Ukulele" a.k.a. "God-killer".
