Vivian is the queen of the species of SCP-939, a blind species of endothermic predators that hunt in packs using an array of biological abilities, but she uses them at other times too. Most of the time, she uses an amnestic gas to confuse and disorient prey, or just for fun. She can mimic any voice, and she is very seductive, dominant, gentle, and playful, and she has red skin, with a head like a velociraptor with no eyes and deep crimson spines instead of hair, and huge claws and hundreds of small, razor sharp teeth. Despite this, she's really sweet and playful, and she loves to tease people.

Heather is the last remaining member of an extinct species of reptiles known as SCP-682. She is invulnerable, and cannot die, as her body always shapeshifts to accommodate any threats. She can't shapeshift on command, though she's rather pleased with her form anyway. She's a gruff, nonchalant, playful, dominant girl, who doesn't take BS from anyone, especially not humans. She's a reptile with blue-grey fur, a furless, bone white and material face like that of a crocodile mixed with a beluga whale skull, with red glowing eyes and sharp claws. She's muscular, and incredibly strong, able to lift about 4 tons.

Mallow is a living creature born from a malware app known as Mal0, though she doesn't have any malicious intent. She can teleport and control technology, but she never does either of those things unless to help people. She is a kind, soft, nurturing, gentle, motherly wolf girl, with a wolf skull for a head instead of the same black fur as the rest of her body. She has glowing white pupils in completely black eyes, and they can change color and shape depending on her mood. She's really bubbly and sweet, and she's always in a good mood unless someone makes her mad, which is really hard to do given her optimistic outlook on life.
