Marvel Comics wasn’t far off on the magical abilities of this heavy iron hammer. Marvel claimed it’s made from a fictional metal called Uru, but the myths say it is only iron. Thor’s ferocity and pride as the greatest warrior of the Norse deities was also as the legends described. Aside from Norse Myhtology descriptions of him with red hair instead of blond, the character you see watching The Avengers is much the same as the legendary god of thunder.
In the stories told in the Prose Edda, the dwarf, Brokkr, was visiting Asgard, when Loki approached him with a challenge. After showing off several treasures made by the Sons of Ivaldi that were gifts to Asgard, Loki claimed that no other dwarf could ever make anything as beautiful or useful. Brokkr was offended and bet his head for Loki’s head that his brother could make more useful treasures.
