LONG HORSE is an urban legend created by Canadian horror artist Trevor Henderson (A.K.A. @SlimySwampGhost)

Long Horse is an entity that isn't evil in any way, unlike all the other creations of Trevor Henderson. Long Horse's purpose seems to be to protect the human race from other entities that mean harm.


  • SCP: NO


Long Horse's appearance is a, well, long horse. But even though the name sounds self-explanatory, it isn't entirely. Long Horse isn't just a long horse, but actually a Horse's skull with no jaw bone connected to a seemingly infinite neck that goes out of our field of view. The neck has patches of dark mane, and the neck can twist and bend in every direction, and it appears the creature can add or subtract as many bones from its neck as it desires, and it's unknown if the entity even has an actual body and legs somewhere, but no sightings can tell, and any outdoors sightings report it to seem as if the neck extends into the heavens and beyond, out of sight.

Story/ Biography

Long Horse was established as a legend when a picture of the creature started spreading over the Internet since 24th August 2018, when a user named Trevor Henderson published a picture showing Long Horse, with the description that the user had a dream of the horse beforehand.

Future on, another picture has been released of the creature by Trevor, where it appears to be in the suburbs, and he named the creature Long Horse. An ancient cave painting has also been found of the Long Horse around three humans, and in the description it is revealed that Long Horse has been around since ancient times.  

Interestingly enough, the ancient drawing depicts that Long Horse is the humans' protector. It is purely harmless, and its goal is to warn humans of upcoming dangers. If a human hears a neck crack or sees the long neck of the creature, the message is that a disaster will occur, not because of Long Horse, but because of what will happen later on.

One more picture of Long Horse has been posted. It simply says, “a new sighting. it's on the move”, meaning Long Horse is most likely going somewhere to warn the people in that area of an upcoming disaster.

Powers/ Abilities

Long Horse is able to foretell disasters and teleport, and he uses these abilities to warn others. He is able to break physics due to the infinite nature of his neck, and he can defy gravity and seemingly levitate. He can contort his body and adjust the number of joints in his neck, and the neck doesn’t have to connect in linear space.

Long Horse can enter people’s dreams, and Trevor once mentioned that if someone were to stare at Long Horse’s neck for a while without looking away, it would eventually crumble into dust, which would most likely not affect Long Horse due to his paranormal nature. He can also give off the smell of cinnamon. It is speculated by some that Long Horse is an angel sent by God.

It can survive being fluctuated through existence and non-existence, as well as being described by Trevor as a "needle threading between the layers of reality"

It is also implied that Long Horse culminates above the 12 dimensional layers in the verse, judging from it's infinite size, it is likely able to cross itself between up to an infinity of dimensions, which makes it one of the strongest entities in the entire verse.

Maybe at the culminating point in the center of where many dimensional layers meet, like a nucleus with the neck and head projecting out”.
