Thor arrives inJourney into Mystery#83 (August 1962), created by Stan Lee, Larry Lieber and Jack Kirby in the guise of Dr. Donald Blake. The character then went through more than sixty years of major editorial changes: the renaming of the title toThe Mighty Thorwith number 126 in 1966, the arrival of Beta Ray Bill under the pen of Walt Simonson in 1983, the periods where the hero lost his hammer and his name, then the taking of the mantle by Jane Foster in 2014. Each editorial shift has redesigned the hierarchy of numbers sought by collectors.
Few Marvel characters have an editorial biography as eventful as that of Thor. Where other heroes maintain a stable identity over decades, the god of thunder has changed costume, status, hammer wielder and even gender over the course of successive writers on the title. This voluntary instability, orchestrated by authors like Walt Simonson, Jason Aaron or Donny Cates, is precisely what makes its history as rich to study as it is to collect.
This article focuses on the trajectory of the character himself: how Thor went from a New York doctor with a cane to a wandering Asgardian god without a hammer, and then to a woman bearing the hero's name.

From Norse Mythology to Journey into Mystery #83
At the beginning of 1962, Marvel sought to diversify its catalog of costumed heroes after the success of the Fantastic Four and Hulk. Stan Lee, too busy to write the introductory script himself, entrusted the writing to his brother Larry Lieber, while Jack Kirby took care of the pencils. The trio draws on Nordic mythology to build a character different from the others: a god, and not a mutant or an irradiated scientist.
Journey into Mystery#83, dated August 1962 (released on newsstands June 5, 1962), introduces Dr. Donald Blake, an American doctor on vacation in Norway. Pursued by alien invaders, the Stone Men from Saturn (the Kronans), Blake takes refuge in a cave where he discovers a cane which, struck against a rock, transforms him into Thor, god of thunder. This same box introduces Mjolnir, the enchanted hammer which will become the character's most recognizable attribute, as well as the first collective appearance of the Kronans. Inker Joe Sinnott, colorist Stan Goldberg and letterer Artie Simek complete a team that lays, from this issue, the visual foundations of the character.
The rest follows very quickly. From the following issue appears Loki, the adopted half-brother and eternal rival of Thor, inJourney into Mystery#85 (date September 1962), which also introduces Heimdall and a first allusion to Odin. In just three issues, Marvel has already established the founding triangle of modern Asgardian mythology: Thor, Loki and the pantheon of Asgard. This frantic editorial pace, typical of the early 1960s, explains why the very first issues of the series concentrate a density of first appearances rarely equaled elsewhere in the Marvel catalog.
The renaming to The Mighty Thor
For several years, the character remained a feature within a larger anthological title. It was only with number 126, dated March 1966, thatJourney into Mysteryis officially renamedThe Mighty Thoron the cover (the interior legal notice simply changes toThor). This change of title, decided when the character has become one of Marvel's standard-bearers alongside Spider-Man and the Fantastic Four, marks the transition from a secondary hero to a full-fledged headliner. For collectors, this shift creates a clear dividing line in the numbering: purists still distinguish the eraJourney into Mystery(#83 to #125) of the eraThorproper, which begins at #126.
From Donald Blake to Odinson: mutations of identity
What sets Thor apart from most Marvel heroes is the number of times his very identity has been called into play by the writers. These flip-flops are not simple cosmetic makeovers: they redefine the character and, with it, the hierarchy of numbers considered key by collectors.
The first big turning point came in 1983 with the arrival of Walt Simonson as script and drawing artist. InThor#337 (date October 1983, released on newsstands October 31, 1983), Simonson introduces Beta Ray Bill, an extraterrestrial cyborg in the service of his people who proves worthy of lifting Mjolnir, a first for a being outside the Nordic pantheon. This issue opens a run that has become cult, considered by a large part of the reading community as one of the creative peaks of the character. The rivalry between Thor and Bill is resolved by a duel in Skartheim: Odin, faced with an impasse, orders the manufacture of a second weapon, Stormbreaker, forged by the dwarves including Eitri, so that Bill can carry his own hammer without depriving Thor of his. Simonson's run continues until number 382, a duration which remains a benchmark in terms of author-designer coherence on the title.
Other arcs have temporarily removed the hammer or even the identity of Thor: periods where the hero wanders without Mjolnir, unable to prove himself worthy of it, to arcs where another character (like Eric Masterson in the 1990s) takes on the costume in his absence. These sequences, less commercially popular than the major first appearances, nevertheless remain important milestones for understanding the evolution of the character: they establish the idea, recurring since, that the title of Thor is not attached to a single person but to the capacity to prove himself worthy of the hammer.
The Jason Aaron era: Gorr, the God Butcher and Jane Foster
The most significant editorial turning point of the 21st century came in 2012, when screenwriter Jason Aaron took over the title withThor: God of Thunder#1, drawn by Esad Ribic. This run, which spans nearly seven years and a hundred issues untilKing Thor#4 in 2019, is today considered one of the most accomplished sagas in the history of the character, almost twice as long as that of Simonson. Aaron builds an ambitious structure by simultaneously exploring three eras of Thor's life: the impulsive young god, the adult Avenger, and the distant future King Thor.
It is in this run that Gorr the God Butcher appears, an antagonist who has become one of the great villains of the Thor mythology, whose influence has extended to the cinema. Aaron also introduces, in 2014, the arc in which Thor finds himself deemed unworthy to lift Mjolnir: the hammer remains inert on the lunar soil, and it is Jane Foster, the hero's former companion and then undergoing treatment for cancer, who proves capable of lifting it and becomes the new Thor. This shift, which sparked both lively debates and a renewed media interest in the title, has had a lasting impact on the editorial history of the character: it demonstrates that the name "Thor" designates, in Marvel continuity, a transferable title rather than a fixed identity.
After Aaron's departure, Donny Cates takes over withThor(2020), continuing the exploration of a character who became king of Asgard then, later, bearer of a whole new cosmic status. These recent developments illustrate the continuing editorial vitality of the title, even almost sixty years after its creation.
The impact of adaptations on the rating
The arrival of Chris Hemsworth in the role in the cinema in 2011 profoundly changed the perception of the character among the general public, and in turn the demand on the market for vintage comics. Two films in particular had a visible effect on interest in the character:Thor: Ragnarok(2017), directed by Taika Waititi, which grossed approximately $855 million at the worldwide box office ($316 million in the United States and Canada, $539 million internationally), andThor: Love and Thunder(2022), which totaled approximately $760.9 million worldwide ($343.3 million North America, $417.7 million internationally).
Thor: Ragnaroknotably popularized the buffoonish tone and the cosmic aesthetic which owe a lot to Simonson's run, reviving interest inThor#337 and the Beta Ray Bill saga to a new generation of readers.Thor: Love and Thunder, for its part, freely adapts the arc of Jane Foster in Mighty Thor created by Jason Aaron, which mechanically brought back to lightThor#1 (2014, Marvel NOW era) and the numbers associated with this transition. This phenomenon, common on characters with strong cinematographic exposure, does not guarantee a stable numerical value: it results above all in a one-off increase in demand and in the volume of searches, more than in a lasting revaluation of late prints, which are generally abundant on the market.
For founding Silver Age numbers likeJourney into Mystery#83 and #85, the effect of the adaptations remains marginal compared to the intrinsic weight of rarity: these comics are more than sixty years old, circulated widely before the era of organized collecting, and are today found in limited numbers in the high grades. It is this structural rarity, much more than cinematographic news, which explains their status as a sought-after collector's item.
Buying guide
- Distinguish clearly between the two eras of numbering.A seller who advertises "Thor #85" may be referring toJourney into Mystery#85 (1962, first appearance of Loki) or has a series numberThorrestarted later. Always check the exact title indicated on the cover and title page.
- Verify the authenticity of reprints.Major Silver Age numbers likeJourney into Mystery#83 have been the subject of multiple reissues and facsimiles over the decades; Compare the paper, printer's credit and original cover price before making any major purchases.
- Prioritize the condition of the binding and corners to the very first issues.At more than sixty years old, very high grade copies are rare: a complete but worn copy often remains a better reading investment than an incomplete copy at a low price.
- Identify precisely the run that interests you.A reader looking for the Beta Ray Bill arc should targetThor#337 to #340 by Walt Simonson; a reader looking for the Jane Foster flip must targetThor#1-8 (2014) by Jason Aaron, not the earlier or later runs sometimes bearing a similar number during editorial relaunches.
- Don't just rely on the title of the recently released film.A peak of interest around a cinema release often temporarily increases the prices displayed; compare several recent completed sales rather than a single current ad to judge the real market price.
- Use structured tracking of your collection.To precisely catalog your copies by title, number and editorial era (Journey into Mystery vs Thor), thecomic collection management applicationallows you to avoid the numbering confusions mentioned above.
