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.
J. R. R. Tolkien's influences
Similarly, the Valar also contain elements of Norse mythology. Several of the Valar have characteristics resembling various Æsir, the gods of Asgard. Thor, for example, physically the strongest of the gods, can be seen both in Oromë, who fights the monsters of Melkor, and in Tulkas, the physically strongest of the Valar. Manwë, the head of the Valar, exhibits some similarities to Odin, the "Allfather".
