Name: Jack Bright

One of the Foundation's three major troublemakers. He is effectively immortal due to SCP-963, "The Immortal Amulet" (though he seems to strongly desire release from immortality).

An authority on bioengineering and anomalous genetics. He is appointed as the Director of Personnel at Site-17. He often tries to make bets with Foundation members, and it is recommended not to take them.

Having an immortal body and too much time on his hands, he has caused numerous incidents at the Foundation. As a result, there is an official "List of Things Dr. Bright Is No Longer Allowed to Do at the Foundation."

Alias: Alto Clef

One of the Foundation's three major troublemakers. A mysterious employee about whom many rumors circulate, such as the impossibility of photographing his face by known means, combat skills that rival top agents, and the existence of a third eye.

He is always seen walking around with a ukulele, wearing a Cheshire Cat-like grin. Due to his caustic personality, penchant for lying, and the annoying habit of walking through low-security areas with a flattened cinnamon roll stuffed up his nose, he is disliked by many staff members. He has a long-standing connection with Dr. Kondraki.

One of the Foundation's three major troublemakers. He is the "King of Butterflies," favored by SCP-408, "Illusory Butterflies."

His specialties are photographing anomalous objects and fencing. He is somewhat indifferent to interpersonal relationships, to the point of not remembering colleagues' names after five years. Conversely, he will go to great lengths to harass anyone who annoys him. He has a long-standing connection with Dr. Clef.

Name: Charles Gears

An excessively logical and polite individual. To observers, he is loyal to his duties to the point of being cold-blooded. People around him call him the "Cogman" because he works like a machine. At the same time, he is an honest man who is poor at lying or deceiving others.

He lacks or has a paralyzed reflex for surprise and fear, making him unable to react emotionally to external stimuli. However, he claims this does not mean he lacks emotions. Dr. Iceberg is his subordinate.

A low-level researcher at the Foundation whose body temperature has been maintained at -7°C since a certain incident. A workaholic, his promotions are repeatedly denied by the O5 Council simply because he is "too useful."

He is foul-mouthed, self-centered, and has a negative personality. He is the type to confront superiors with explosives in hand, but he seems to trust Dr. Gears alone.

Name: Simon Glass

Head Psychologist who performs regular psychological evaluations on Foundation staff and humanoid SCPs. He is a rare voice of reason within the Foundation, but consequently, he is often pushed around by those around him.

While others describe him as being soft-hearted, he is trusted for his high empathy and kindness.
