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.
Njörun
In Norse mythology, Njörun (Old Norse: "Njǫrun", sometimes modernly anglicized as "Niorun") is a goddess attested in the "Prose Edda", written in the 13th century by Snorri Sturluson, and various kennings (including once in the "Poetic Edda"). Scholarly theories concerning her name and function in the pantheon include etymological connections to the Norse god Njörðr and the Roman goddess Nerio, and suggestions that she may represent the earth or be the unnamed sister-wife of Njörðr.
