Thor debuted in the science fiction/fantasy anthology title Journey into Mystery #83 (cover-date Aug. 1962), and was created by editor-plotter Stan Lee, scripter Larry Lieber, and penciller-plotter Jack Kirby. A different version of the mythological Thor had appeared previously in Venus #12-13 (Feb.-April 1951).
In a 1984 interview Kirby said “I did a version of Thor for D.C. in the Fifties before I did him for Marvel. I created Thor at Marvel because I was forever enamored of legends, which is why I knew about Balder, Heimdall, and Odin. I tried to update Thor and put him into a superhero costume, but he was still Thor.” And in a 1992 interview, Kirby said “[I] knew the Thor legends very well, but I wanted to modernize them. I felt that might be a new thing for comics, taking the old legends and modernizing them.”
Journey into Mystery was retitled Thor (per the indicia, or The Mighty Thor per most covers)with issue #126 (March 1966). “Tales of Asgard” was replaced by a five-page featurette starring the Inhumans from #146–152 (Nov. 1967 – May 1968), after which featurettes were dropped and the Thor stories expanded to Marvel’s then-standard 20-page length.
During the 2008 “Secret Invasion” storyline, Thor rescues and heals Beta Ray Bill, who after being temporarily given Mjolnir, aids Thor in defending Earth against an invading force of alien Skrulls. Due to Loki’s deception, Thor battles and kills his grandfather Bor, and is banished from Asgard. With Thor’s hammer Mjolnir damaged in that battle, Thor seeks out Doctor Strange, who is only able to repair the hammer by transferring the Odinforce from Thor to Mjolnir, binding the two in a symbiotic relationship. With the repaired hammer, Thor is able to draw out the imprisoned Sif, and return her to her own body, thereby restoring Loki to his male body in the process.
Walt Simonson took over both writing and art as of #337 (Nov. 1983). His stories placed a greater emphasis on the character’s mythological origins. Simonson’s run as writer-artist lasted until #367 (May 1986), although he continued to write – and occasionally draw – the book until issue #382 (Aug. 1987). Simonson’s run, which introduced the character Beta Ray Bill, was regarded as a popular and critical success.Simonson’s later stories were drawn by Sal Buscema, who describes Simonson’s stories as “very stimulating. It was a pleasure working on his plots, because they were a lot of fun to illustrate. He had a lot of great ideas, and he took Thor in a totally new direction.” Asked why he was leaving Thor, Simonson said that he felt the series was due for a change in creative direction, and that he wanted to reduce his work load for a time. After Simonson’s departure, Marvel’s editor-in-chief at the time, Tom DeFalco, became the writer. Working primarily with artist Ron Frenz, DeFalco stayed on the book until #459 (Feb. 1993).
Journey into Mystery was initially published by Atlas Comics, then by its successor, Marvel Comics. Initially a horror comics anthology, it segued to giant-monster and science fiction stories in the late 1950s. Beginning with issue #83 (cover dated August 1962), it ran the superhero feature “The Mighty Thor“, created by writers Stan Lee and Larry Lieber and artist Jack Kirby, and inspired by the mythological Norsethunder god. The series, which was renamed for its superhero star with issue #126 (March 1966), has been revived three times: in the 1970s as a horror anthology, and in the 1990s and 2010s with characters from Marvel’s Thor mythos.
After Kirby left the title, Neal Adams penciled issues #180–181 (Sept.-Oct. 1970).John Buscema then became the regular artist the following issue. Buscema continued to draw the book almost without interruption until #278 (Dec. 1978). Lee stopped scripting soon after Kirby left, and during Buscema’s long stint on the book, the stories were mostly written by Gerry Conway, Len Wein, or Roy Thomas. Thomas continued to write the title after Buscema’s departure, working much of the time with the artist Keith Pollard; during this period Thomas integrated many elements of traditional Norse mythology into the title, with specific stories translated into comics form. Following Thomas’s tenure, Thor had a changing creative team.
Loki has now claimed leadership of Asgard, and all must recognize that fact, even Thor. Finally winning the throne after a long sought out fight is not as sweet as he thought it would be. The ones that helped him now demand their due and the favors he promised them, including the death goddess Hela and seductress Lorelei. While he goes about his kingdom, he continually turns to his prisoners, Thor and Sif. Sif berates him for being jealous of her, and of cutting off her golden hair, only to bring about a greater love between her and Thor. While Balder reminds him that he has died and gone to Hel, while there, sees that there are parallel dimension incarnations of Thor, Loki, and Balder: Some different, yet all play the same roles. And Loki’s role is never to rule. Loki then turns to Karnilla, and agrees to free Balder into her care, in exchange for her to peer into a myriad other dimensions. There he sees confirmation of Balder’s words, all with Thor triumphant. Loki decides that Thor will indeed die at dawn by beheading. As he’s walking out of the dungeons, he runs into Fárbauti, his birth father. Loki decides to go against fate, and spare his brother as well as free him and Hela is revealed to be a failed illusion cast by Loki to convince him to kill his brother. Thor decides that when breaking free from his prison, he defeats his brother.
