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.
Ragnar Lodbrok
Ragnar Lodbrok or Lothbrok (, "Ragnar shaggy breeches", contemporary Norse: "Ragnar Loðbrók") is a legendary Norse Viking hero and ruler, known from Viking Age Old Norse poetry and sagas. According to that traditional literature, Ragnar distinguished himself by many raids against Francia and Anglo-Saxon England during the 9th century. There is no known evidence to substantiate that he actually existed under this name and outside of the mythology associated with him.
