Long Horse (Trevor Henderson)

Long Horse originated in the modern mythos produced by Canadian horror artist Trevor Henderson and spread through online communities and fan wikis. Sources identify it as one of Henderson's creature designs and situate it in the same creative corpus as Siren Head and Cartoon Cat; fandom pages and summaries record images, captions, and community commentary that extended the concept into a brief fictional cosmology and claims of antiquity within that fictional setting (e.g., references to an 'ancient drawing'). The entity is therefore a product of contemporary participatory myth-making rather than historical folklore (Sources: fandom summaries and encyclopedia entries reporting Henderson's creations).

Fandom summaries consistently describe Long Horse as having a horse's skull for a head (notably described as lacking a lower jaw) attached to an extremely long neck that extends beyond the field of view and is described in some sources as 'seemingly' or 'officially' infinite; the neck is said to be able to twist and turn at any angle. Sources emphasize the skull-and-neck image rather than a full, detailed equine body; details such as coloration, presence of limbs, or other anatomical features are not documented in the provided sources (Sources: fandom pages and summaries).

In the documented fandom accounts, Long Horse is characterized primarily by its protective intent toward humans rather than by a catalogue of supernatural powers. Sources describe it as 'not evil' and as seeming to 'protect the human race from other entities that mean harm.' Physical attributes emphasized in sources are the extremely long, highly flexible neck and inferred antiquity from depictions described in fandom material (an 'ancient drawing' said to depict Long Horse with humans). The provided material does not ascribe additional powers such as speech, telepathy, teleportation, enforced bargains, or feeding behaviors (Sources: fandom summaries and wiki pages).
