The best Thor story arcs are The Surtur Saga by Walt Simonson (Thor #337-353, 1983-1985), God Butcher/Godbomb by Jason Aaron (God of Thunder #1-11, 2012-2013), and The Death of the Mighty Thor (Mighty Thor #700-706, 2018). These three character-defining arcs represent the pinnacle of Marvel superhero storytelling.

Thor benefits from a unique narrative advantage among Marvel superheroes: his mythological dimension allows the writers to explore epic themes – the mortality of the gods, destiny, sacrifice – with an amplitude impossible for characters more anchored in everyday life. This thematic richness has produced some of the most memorable arcs in American comic book history.

This ranking analyzes in depth Thor's essential arcs, their impact on the character and the medium, as well as their value for the collector. Each arc is evaluated on its narrative quality, historical significance, and the desirability of physical issues on the secondary market.

The Surtur Saga — Walt Simonson (Thor #337-353)

The Surtur Saga is unanimously considered to be the absolute pinnacle of Thor in comics. Walt Simonson, providing both the scenario and the drawings, builds over 17 issues a masterful narrative crescendo which culminates in the final battle of Asgard against the fiery demon Surtur.

The arc begins with the shattering introduction of Beta Ray Bill (Thor #337) and gradually weaves several narrative threads: the forging of the Twilight sword by Surtur, Thor's quest to protect the Earth, Loki's intrigues, and Balder's transformation. The climax in #353, where Odin and his brothers Vili and Ve face Surtur while all the forces of Asgard fight on the Bifrost, remains one of the most spectacular sequences ever drawn in a comic.

God Butcher / Godbomb — Jason Aaron and Esad Ribic (God of Thunder #1-11)

The first arc of the Jason Aaron run is a masterpiece of narrative construction. Gorr the Butcher of the Gods, a mortal broken by the silence of the gods in the face of his suffering, undertakes a millennia-old crusade to exterminate all the deities of the universe. The story interweaves three temporalities – the young Viking Thor, Thor Avenger of the present, and King Thor of the future – to create an epic fresco about faith, doubt and divine responsibility.

The strength of this arc lies in its construction: each temporality enriches the others, the revelations about Gorr gain power over the issues, and the conclusion "Godbomb" (#6-11) raises the stakes to a cosmic level without losing emotional intimacy. Esad Ribic delivers plates of rare pictorial beauty, with a sense of composition reminiscent of the great classical painters.

Market Impact: God of Thunder #2 (first complete Gorr) became one of the most sought-after modern issues after the adaptation in Thor: Love and Thunder. The rating continues to rise because Gorr's character has barely explored cinematic potential.

The Death of the Mighty Thor — Jason Aaron and Russell Dauterman (Mighty Thor #700-706)

The conclusion of the Jane Foster Thor arc is one of the most emotional stories in Marvel history. Jane Foster, suffering from cancer, knows that each transformation into Thor cancels out her chemotherapy and brings her closer to death. When the Mangog threatens to destroy Asgardia, Jane makes the ultimate choice to transform one last time, knowing it will be fatal.

Russell Dauterman and colorist Matthew Wilson produce exceptional visual work, with double-page spreads that alternate between the cosmic majesty and the heartbreaking intimacy of Jane's final moments. #705, "The Death of the Mighty Thor", is one of the most perfect singles of the 2010s.

Numbers to remember:

Thor's Ragnarok — Michael Avon Oeming (Thor vol.2 #80-85)

In 2004, Marvel decided to end Thor for the first time. Michael Avon Oeming and Andrea DiVito deliver a devastating final arc: the real Ragnarok, not a simulation. Thor discovers that Asgard's cycle of destruction and rebirth is being manipulated by higher entities (Those Who Sit Above in Shadow) and chooses to break the cycle once and for all—destroying Asgard and sacrificing himself.

This arc was underrated upon release but is gaining critical recognition. The issues remain very affordable (CGC 9.8: $30-50 each) making them an excellent prospective purchase for patient collectors.

Tales of Asgard — Stan Lee and Jack Kirby (Journey into Mystery #97-125)

The “Tales of Asgard” backup stories published in Journey into Mystery starting with #97 are the genesis of the entire Thor mythology at Marvel. In 5-8 pages per issue, Lee and Kirby build a universe of astonishing richness: the Nine Kingdoms, Ragnarok, Yggdrasil, the origins of Odin, the childhood of Thor and Loki.

Kirby produces some of his most beautiful pages there, freed from the constraints of the classic superheroic story. These stories have been compiled into a dedicated Omnibus, but the original issues are of particular value to collectors of Kirby's work.
