Thor (comics)
Thor, a founding member of the superhero group the Avengers, often battles his evil adoptive brother Loki, a Marvel character adapted from the Norse god of mischief. He is among Marvel's most powerful superheroes. Many recurring characters in his stories are based on Norse Mythology. Apart from this main superhero, Marvel features a number of characters based on him.
Nanna (Norse deity)
In Norse mythology, Nanna Nepsdóttir or simply Nanna is a goddess associated with the god Baldr. Accounts of Nanna vary greatly by source. In the "Prose Edda", written in the 13th century by Snorri Sturluson, Nanna is the wife of Baldr and the couple produced a son, the god Forseti. After Baldr's death, Nanna dies of grief. Nanna is placed on Baldr's ship with his corpse and the two are set aflame and pushed out to sea. In Hel, Baldr and Nanna are united again. In an attempt to bring back Baldr from the dead, the god Hermóðr rides to Hel and, upon receiving the hope of resurrection from the being Hel, Nanna gives Hermóðr gifts to give to the goddess Frigg (a robe of linen), the goddess Fulla (a finger-ring), and others (unspecified). Nanna is frequently mentioned in the poetry of skalds and a Nanna, who may or may not be the same figure, is mentioned once in the "Poetic Edda", compiled in the 13th century from earlier traditional sources.
