The pair has been compared to similar figures found in Greek, Roman and Vedic mythology, and may also be connected to beliefs surrounding the Germanic "wolf-warrior bands", the Úlfhéðnar.
[4] Bruce Lincoln further traces Geri back to a Proto-Indo-European stem *gher-, which is the same as that found in Garmr, a name referring to the hound closely associated with the events of Ragnarök.
[15] If the rider on horseback on the image on the Böksta Runestone has been correctly identified as Odin, then Geri and Freki are shown taking part in hunting an elk.
[17] Historian Michael Spiedel connects Geri and Freki with archaeological finds depicting figures wearing wolf-pelts and frequently found wolf-related names among the Germanic peoples, including Wulfhroc ("Wolf-Frock"), Wolfhetan ("Wolf-Hide"), Isangrim ("Grey-Mask"), Scrutolf ("Garb-Wolf"), Wolfram ("Wolf (and) Raven"), Wolfgang ("Wolf-Gait"), Wolfdregil ("Wolf-Runner"), and Vulfolaic ("Wolf-Dancer") and myths regarding wolf warriors from Norse mythology (such as the Úlfhéðnar).
[19] Philologist Maurice Bloomfield further connected the pair with the two dogs of Yama in Vedic mythology, and saw them as a Germanic counterpart to a more general and widespread Indo-European "Cerberus"-theme.
