Adeline Abendroth, or "Slender Doll Ally," is a human/doll/slender-being hybrid that serves Slenderman. She also has another form called "Nightmare" or "Nightmare Ally".


Ally was born on December 6th, 1895, in East Berlin, and raised by the youngest of her older brothers, Jonathan. She was born with Undifferentiated Schizophrenia, and she was shunned by her mother and two oldest brothers and abused by her father.

At 5, she was sent to the Black Wood Asylum outside of Berlin and kept there for the remaining five years of her life. Leading up to her death, she was hunted down as she fled the asylum through the woods. The result: she was murdered by being cut into pieces with a hatchet. Her limbs were cut off, her chest cavity was cut open, and her head and neck suffered some damage. Several months later, she was resurrected by Slenderman.

She was stitched together in preparation for resurrection, creating the haphazard stitching all across her body. Then gears and a key were inserted into her spine and back. Finally, Slenderman created a soul gem to bind her soul to her body. While creating the gem, some of his blood got mixed into the formation of the crystals, which caused some of his abilities to transfer into Ally. She only has weak copies of some of Slenderman's powers. These powers are too much for a human soul, though. It aggravated her schizophrenia, causing the two halves of her mind to divide into her Normal Form (which is her human side) and her Nightmare Form (Her monster/Slender-being side).


Normal Form: Ally is sweet to the ones she knows. She's very curious about her surroundings. She is dependent on her older protectors and friends. She's sometimes overprotective when it comes to her "family." She tends to be clingy to certain people. She's sensitive to certain emotional stimuli, and a little emotionally unstable if riled up.

Nightmare Form: Nightmare tends to be moody, sharp-tongued, sarcastic, mature, protective of her other side, predatory while fighting, and sly. Childish but in a more twisted sense- this is the personality trait that shows when Ally normally goes Nightmare. It resembles a psychotic adolescent. It involves her glee and pleasure to harm and kill everything that she could get her hands on- including the one who pissed her off.

Weapons/Special Items:

  • Surgical knives (Main weapon/Normal Form)
  • Chef/Butcher Knives (Nightmare Form) (Alternates between forms- It transforms to make the weapon more dangerous and heightens the danger factor).
  • Claws and teeth (Nightmare Form).
  • Her tendrils (Both forms).


  • She is very agile. When in Nightmare Form, she can contort her body due to her flexible spine. If she stretches too far, though, the wires connecting her gears might come taut. This will halt her movements and cause her great pain.
  • She has inhuman strength in her tendrils and her body. It shows most when she is pissed.
  • Sometimes, when she is in trouble, she will use her wit. She may think ahead to block an opponents attack or find an escape route to flee, despite her childish demeanor.
  • She is immune to poison and psychic attacks.
  • She is psychically in-tuned to surroundings, so she has a knack of picking up intruders within her area.
  • She is resourceful when cornered.


  • Electricity stops the key in her back, temporarily paralyzing her.
  • Sharp objects such as knives, glass, blades, etc. She has human organs and can be stabbed and slashed.
  • If burned, her skin can't heal itself.
  • Her tendrils can be ripped out or cut off, causing loss of blood over a long period of time.
  • Her key is her weakest spot in combat, as well as her most vital part). When Ally's key is pulled out, it causes the gears embedded on her spine to stop turning, making her fully paralyzed and unable to move. It can also cause a slow death from a lack of oxygen circulation from the blood through the heart. A side effect of this method is that each time you pull it out in her Nightmare Form, it gets harder and harder to pull out each time afterwards.
  • Exorcism and necromancy. She's undead.
  • Her Turquoise Soul Gem, which anchors her soul to her body. It's the main source of her powers, due to the Slender blood being trapped in the crystals.
  • During the winter months, she sleeps heavily in a hibernation phase for several weeks on end, so she is vulnerable and unable to fight back due to being in deep sleep.
  • She is afraid of doctors, nurses, the dark, fire, and electricity.


  • She is very emotionally unstable.
  • She has no pigment in her hair, so it's white. She also has little to no pigment left in her skin, so it has a grey tint to it, similar to a corpse.
  • She's 118 years old, but she looks 18 years old. Due to dying at the age of 10, she is stuck with the mentality of a ten year old despite her appearance.
  • Due to her mental illness, she can act violently, she exhibits argumentativeness, and she claims to hear voices and see things that aren't there. It also causes her to have a childish mentality, despite her age.
  • She's not technically considered a proxy, as the proxies protect her when they are idle, but still follows the rules and takes orders from Slenderman.
  • She gets overwhelmed if there is too much emotion or stress and might go nightmare without meaning too, and hides from her fears.
  • Her brass key is the only way she moves around and survives. It's connected to gears within her spinal cord. Those gears are connected to blood veins, nerves, and other connections, to keep her organs and other body functions working.
  • She carries a comfort toy: a black voodoo doll. She hates to part with it. Take it away from her and she will throw a fit!
  • Carries around black thread and a sewing needle just in case her seams in her skin come loose from age or damage.
  • During winter months, Ally, due her slender-being side, tends to hibernate with long bouts of slumber for a week or so and awaken for a few days of alertness before going back to sleep. It's odd, but it also makes the job for protecting her much easier for the idle proxies.
  • If in front of a mirror, Ally herself will see her normal reflection. However, bystanders might actually see a glimpse of Nightmare Ally instead in place of the doll's reflection.
  • She has memory "blanks" every time she recovers from her Nightmare Form. She will not remember anything that has happen during that time. She call these blanks "Blackouts".
  • Her birthday is on December 6th, 1895.
  • Her Nightmare Mode is a last resort attack- if Ally gets too worked up in anger, sadness, or any other strong negative emotion, if she gets extremely afraid, or if she is wounded enough that she can't fight back, it triggers her Nightmare Form transformation.
  • Her Nightmare Side can take more damage and pain than her normal self, causing the illusion of being indestructible. If she gets too overwhelmed, though, she will collapse, due to either blood loss or just an overload of pain reception.
  • Ally regards Slender Man as a father figure, since, in her mind, and the discovery of her similar powers, she just assume that she must be related to him. This isn't the case...she was just a product of a resurrection gone wrong.
  • She tends to shy away from strangers that she detects are slightly dangerous or a threat.
  • Her creator is Invaderlka
