Jason Aaron’s time writing Thor – from Thor: God of Thunder to Thor to The Mighty Thor to Thor (again) to War of the Realms to King Thor – produced the defining version of the character. No one, at least in my humble opinion, has ever done more with Thor nor understood the character, their world, and its theological fertility more than Jason Aaron. Jane Foster lifting Mjölnir to become Thor herself was the heart of Aaron’s run. But for that to happen, Thor Odinson had to find himself unable to lift the hammer. This idea – the idea of Thor being unworthy – ties together much of what Aaron did. Its seeds were sown in his very first arc, as Thor faced the brutality of Gorr the God Butcher. Its actualization would lead to Jane lifting Mjölnir and becoming the mightiest Thor and the greatest of all the gods. Its effects would culminate in Thor Odinson’s climactic battle with Malekith the Accursed during the War of the Realms and it would shape the sort of king Thor would become.
