Loki
A regular at Valhalla, home of the Norse gods, Loki was not a god but a particularly mischievous Trickster (see above). Blood-brother to Odin, King of the Gods, Loki usually escaped serious retribution from his wildly cunning exploits. Often, however, the gods required he right his vicious pranks, including his theft of Idunn's Golden Apples of Immortality. Like his West African counterpart Anansi (see above), Loki possessed the ability to assume the form of various animals.
In 2.15 Tall Tales, Bobby says that there is a Trickster or demi-god in Scandinavia named Loki.
In 5.19 Hammer of the Gods, it is revealed that Gabriel, who has been hiding on Earth as a Trickster for millennia, is known to a group of pagan gods as Loki.
