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.
Eir
In Norse mythology, Eir (Old Norse "help, mercy") is a goddess or valkyrie associated with medical skill. Eir is attested in the "Poetic Edda", compiled in the 13th century from earlier traditional sources; the "Prose Edda", written in the 13th century by Snorri Sturluson; and in skaldic poetry, including a runic inscription from Bergen, Norway from around 1300. Scholars have theorized about whether these three sources refer to the same figure, and debate whether Eir may have been originally a healing goddess or a valkyrie. In addition, Eir has been theorized as a form of the goddess Frigg and has been compared to the Greek goddess Hygieia.
