Bjarki

Bödvar Bjarki (Old Norse: Bǫðvarr Bjarki [ˈbɔðˌvɑrː ˈbjɑrki]), meaning 'Warlike Little-Bear', is the hero appearing in tales of Hrólfr Kraki in the Hrólfs saga kraka, in the Latin epitome to the lost Skjöldunga saga, and as Biarco in Saxo Grammaticus' Gesta Danorum. He is often depicted with the ability to shapeshift into a bear – see Hamr (folklore).
