Yep, them again. The operatives that the stories go into are all stone cold badasses who have really earned their place, but special mention goes to this fellow:
Dr. Alto Clef. Alto. Fucking. Clef.
He's the Foundation's specialist in dealing with reality benders, people who can bend reality with sheer force of will. He has killed over 100 of them. Let that sink in. He killed more than 100 gods. GODS! There has been speculation in the forums as to whether he is actually human or not (some people claim he's the Devil himself, others claim he's the SCP Foundation version of Alucard from Hellsing. We'll get to him, though, don't worry) while the author sits back and smiles.
Dr. Alto Clef, He'll turn your gun into a fucking bagel.
