The phrase appears as a relational kenning in the Poetic Edda's Völuspá, embedded in the eschatological sequence of Ragnarök. It is not presented as an independent origin-bearing entity in the surviving texts; instead it names the act/role of the slayer of Beli within prophetic mythic narration. Scholarly tradition associates such kenning-phrases with the narrative world of gods, jötnar, and end-time combat rather than with separate cultic biographies.
No independent, detailed physical description is preserved in the sources. One manuscript transmission of the Völuspá line includes the adjective bjart ('bright') qualifying the bane (rendered in glosses as 'Beli's bright bane'); beyond this single adjectival epithet the poetic fragment is lacunary and supplies no fixed iconography.
The only attested action in the source material is the slaying of Beli (the phrase names the slayer). The line situates that deed within the wider combative frame of Ragnarök (adjacent to lines about Óðinn fighting the wolf and references to Surtr). No other powers, habitual behaviors, or interactions with humans are described in the provided texts. Where the kenning is taken to refer to a known deity (see sources), broader attributes derive from that deity's independent attestations, not from the kenning itself.

Odin
Odin (Old Norse: Óðinn) is the chief god of the Norse (Æsir) pantheon, a multifaceted deity associated with wisdom obtained by sacrifice, poetic inspiration, death and warfare, and rulership over the hall Valhöll where chosen slain warriors (einherjar) dwell. He appears throughout Germanic tradition from Roman-era accounts through the Viking Age and in later folklore as leader of the Wild Hunt.

Surtr
Surtr is a foremost fire-associated jötunn in Old Norse myth who stands at the frontier of Múspell (Muspelheim). In eschatological sources he leads the sons of Múspell from the south at Ragnarök, bears a bright flaming sword from which light shines more brightly than the sun, and flings fire that burns the world.
