Aufhocker

No single mythic origin story is recorded in the provided sources. The name is etymological and behavior-defined: Aufhocker literally means 'leap upon', indicating an entity conceptualized around its action rather than a genealogical origin. Scholarly and interpretive accounts treat the figure variously as a punitive presence meting out lessons to thieves or transgressors, as a cultural embodiment of burdens and night terrors, or as a local uncanny inhabitant of liminal landscape features, but these readings are interpretative rather than recorded origin myths in the supplied materials.

Accounts emphasize shapeshifting and an indeterminate form rather than a single canonical appearance: sources list examples such as a goblin, a beautiful woman, a dead man, or various animals. Descriptions concentrate on the entity's behavior (perching/leaping onto victims) and describe its shape as "unidentifiable" in many summaries, with variants differing by teller and locality.

Defining behavior is physical: the Aufhocker leaps onto the backs or shoulders of victims and 'weighs them down with every step', producing progressive exhaustion that often causes death by exhaustion in some tellings. Variants exist in which the creature grips or attacks the throat, linking that form to vampiric motifs. It commonly targets solitary travelers, the elderly in some tales, and sometimes thieves or transgressors in didactic versions. It is associated with night or marginal travel contexts and liminal places where such attacks occur.
