Dr. Alto Clef is an enigmatic scientist and gun enthusiast working for the SCP Foundation. He is known for being one of the most mysterious non O5 employees currently working for the foundation. It is impossible to properly photograph his face for some reason, as it is always swapped with the face of a random animal. He has lead several brutal exterminations against several SCPs, and plans on doing more. He often wears a large hat that conceals most of his face. He also has three eyes.
