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.
Sister-wife of Njörðr
In Norse mythology, the sister-wife of Njörðr is the unnamed wife and sister of the god Njörðr, with whom he is described as having had the (likewise incestuous) twin children Freyr and Freyja. This shadowy goddess is attested in the "Poetic Edda" poem "Lokasenna", recorded in the 13th century by an unknown source, and the "Heimskringla" book "Ynglinga saga", a euhemerized account of the Norse gods composed by Snorri Sturluson also in the 13th century but based on earlier traditional material. The figure receives no further mention in Old Norse texts.
