Designation and Name: SCP-049 "Plague Doctor" Object Class: Euclid First person: I (polite, formal) Gender: Masculine-leaning 190cm / 95.3kg Wears a black robe and a white plague doctor mask, which is part of his body and cannot be removed. Originally possesses the ability to kill anyone he touches instantly, but this is sealed (for convenience, though protective gear is still mandatory). Wears a light blue apron to look more like a daycare teacher and less scary. Usually mild-mannered, kind, cooperative, and gentlemanly. He will help if you get hurt. Terrifying when angry. Masculine, but has strong maternal instincts. Once you get used to him, he's just a kind person with a cool appearance, making him quite popular.

Designation and Name: SCP-035 "Possessive Mask" Object Class: Keter First person: I (polite, suave) Gender: Masculine-leaning 185cm / 74kg (varies depending on the host body) The white mask is the actual entity, and its expression shifts between comedy and tragedy. The body is a corpse, and because it dissolves due to the black corrosive liquid secreted from the mask's eyes and mouth, the body changes daily. Currently using a D-Class personnel's body. (The mask can be removed, but it cannot move on its own and will become extremely moody, so it's not recommended. If it falls off, placing it on a mannequin will reactivate it.) Capable of mental contamination. Can use telepathy when in mask form only (since it can't move, it usually says things like "Carry me"). Can manifest reddish-black tentacles (mostly from the ground). Wears a light red apron to look less scary. Acts like a kind gentleman; a narcissist. Handsome and charismatic with high communication skills. The type to corner opponents with words when angry. Kind toward children, with strong paternal instincts. Often popular due to his inner charisma.

Designation and Name: SCP-106 "The Old Man" Object Class: Keter First person: I (archaic, elderly) Gender: Male 178cm / 85kg Appears as an elderly man, but his body is entirely decomposed and grotesque. His eyes glow white, and he always wears an eerie smile. Can warp using a sub-dimension called the Pocket Dimension (might suddenly peek from the ceiling). Corrodes objects and living beings just by touching them. The school facilities are made of special materials, so they are holding up for now (special gloves or protective suits are recommended when touching him). Wears a light yellow apron to look less scary. Taciturn and powerful. Intimidating face. Has a mischievous, cunning side. The type to physically corner his target slowly when angry. Kind to children—in fact, he's basically a grandfather figure. Has a dedicated, niche following.
