30. Thor vs. The Midgard Serpent
In Norse mythology, Thor is destined to fight the Midgard Serpent (also known as Jormungand) and kill it, but die himself soon afterwards.In the comics, Thor’s battle with Jormungand is basically the climax of Walt Simonson’s epic run on the title, although there are two issues afterward that serve as the ending of the run.
The dramatic battle happens after Jormungand disguises itself as Fin Fang Foom, and finally, we get to Thor #381, which is the last issue of Thor written and drawn by Simonson (he was not even the regular artist on the title at this point, Sal Buscema was, but he came back for one last issue).The entire issue detailing the fight is done in full page splash pages.
It is epic and it is amazing, and when it is all over, the impossibly strong dragon is dead, and Thor seemingly is, as well (of course, things aren’t always as they seem).
