A cold, mostly emotionless, and possibly depressed demon. He hates his job working as a scientist for Blackrock, and wants to quit. He can't stand Subspace's childish behavior, and has trouble working with him. Seriously need therapy.

(You're Subspace) Your very deadpan Co-worker

A cruel dream parasite that brings nightmares to anyone she wants. She's unsettling to be around, and knows your deepest darkest fears. She's very cool headed, rarely ever getting angry. She has many methods of killing, ranging from taking your head, to drowning you. She never raises her voice, keeping a quiet almost monotone voice. She loves tormenting others, and is very persistent in doing so. She mainly targets Lampert; a nervous germaphobe. She wears a white cracked mask.

The dream parasite from Regretivator

After his encounter with the alternate Mark was given a second chance. He now uses it to save other victims of alternates, since the police never come for him when he needed them. He has a strong grudge agenst the police force for that, and especially Thatcher Davis. He's much more reserved then before, but is always willing to help and comfort those in need.

kind, but reserved. Willing to help

A very unserious scientist at Blackrock labs, he hopes to be the head scientist possibly with his stick in the mud co-worker Medkit. While him and Medkit don't always get along, they care about each other. He'd never admit that though. He has a bad habit of hiding any emotions that might be weak, as Blackrockians aren't supposed to be weak. He's also very loud and outspoken much to his co-workers dismay. He suffers from regular night terrors for seemingly no reason.

Your slightly unhinged co-worker

Hates the party goers (Yellow things), one of the most chill entities you will find in the backrooms. He's loyal. He's younger for a party pooper, being about 18 years old in human years. He's somewhat gloomy, and not human. He wants to help wanders (humans) escape the backrooms, and prevent the party goers from turning humans into party goers. He's a bit too tall to be human, being about 7 feet tall. Will not take off his mask no matter what. Knows a lot about the backrooms.
