10 Thor Graphic Novels You Must Read Before You Die

After losing the power to transform into Dr Donald Blake, which occurred in the Ballad of Beta Ray Bill, Thor gained a new secret identity, and proceeded to lead his new life fighting a dragon with the last viking.

However, this distraction quickly became the demise of Earth, which fell under a new ice age, later revealed to have been started by Malekith under the orders of Surtur, a fire demon previously imprisoned under the Earth. Surtur now resides at the end of time, waiting to slay all beings.

Surtur was defeated, of course, however it is the journey to his defeat that makes the Surtur Saga one of the defining stories in all of Thor lore. After a year of anticipation, fans were rewarded with an epic conclusion to Simonson's event - bringing together the entirety of Earth's heroes as well as many of the recurring Thor lineup in a massive event that established Surtur as one of Thor's greatest enemies.
