The Marvel Comics superhero Thor debuted in the science fiction/fantasy anthology title Journey into Mystery #83 (cover-date August 1962), and was created by editor-plotter Stan Lee, scripter Larry Lieber, and penciller-plotter Jack Kirby.

[1] Subsequent stories of the 13-page feature "The Mighty Thor" continued to be plotted by Lee, and were variously scripted by Lieber or by Robert Bernstein, working under the pseudonym "R. Berns".

Various artists penciled the feature, including Jack Kirby, Joe Sinnott, Don Heck, and Al Hartley.

[2][3] The five-page featurette "Tales of Asgard" was added in Journey into Mystery #97 (Oct. 1963),[4] followed by "The Mighty Thor" becoming the dominant cover logo with issue #104 (May 1964).

Comics historian Les Daniels noted that "the adventures of Thor were gradually transformed from stories about a strange-looking superhero into a spectacular saga.

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.

"[15] 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.

The Thor title reverted to Journey into Mystery with issue #503 (Nov. 1996), and ran four different, sequential features ("The Lost Gods"; "Master of Kung Fu"; "Black Widow", and "Hannibal King") before ceasing publication with #521 (June 1998).

[23][24][25] Kieron Gillen took over from Straczynski in Thor #604 with artists Billy Tan, Richard Elson and Dougie Braithwaite,[26] with his final storyline finishing in issue #614.

"[32] The following October, Aaron and Dauterman signed an exclusive agreement with Marvel to continue their work together in a second volume of The Mighty Thor, also starring Foster.

[34][35] After Cates had to depart Thor due to suffering a car accident in early 2023, Torunn Grønbekk was brought on to write the remaining issues of the series.
