Midgard Serpent (Marvel Comics)
Jormungand, also known as The Midgard Serpent or World Serpent, is a fictional character that appears in comic books published by Marvel Comics. The character, based on the serpent Jörmungandr from Norse mythology, first appears in "Marvel Tales" #105 (Feb. 1952), in the period between the Golden Age of Comic Books and the Silver Age of Comic Books.
Brunhild
In the Norse tradition, Brunhild is a shieldmaiden or valkyrie, who appears as a main character in the "Völsunga saga" and some Eddic poems treating the same events. In the continental Germanic tradition, where she is a central character in the "Nibelungenlied", she is a powerful Amazon-like queen. In both traditions, she is instrumental in bringing about the death of the hero Sigurd or Siegfried after he deceives her into marrying the Burgundian king Gunther or Gunnar. In both traditions, the immediate cause for her desire to have Sigurd murdered is a quarrel with the hero's wife, Gudrun/Kriemhild. In the Scandinavian tradition, but not in the continental tradition, Brunhild kills herself after Sigurd's death.
