Thor is a superhero appearing in American comic books published by Marvel Comics. The character, based on the Norse mythological god of the same name, was created by writer Stan Lee, scripter Larry Lieber, and artist Jack Kirby, and first appeared in the anthology title Journey into Mystery #83 in August 1962.
The comic follows Thor Odinson, the Asgardian god of thunder, who is cast down to Earth by his father Odin to learn humility. While trapped in the human form of the disabled physician Donald Blake, Thor learns compassion for humanity. When he strikes his walking stick upon the ground, he transforms back into the mighty Thor, wielding the enchanted hammer Mjolnir. The series blends cosmic fantasy with superhero action, pitting Thor against a vast rogues' gallery including his mischievous adopted brother Loki, the fire demon Surtur, and the world-devouring Galactus.
Over the decades, Thor has been a cornerstone of the Marvel Universe, serving as a founding member of the Avengers and starring in multiple ongoing series, limited series, and graphic novels. The comic's rich mythology, blending Shakespearean drama with Kirby's epic cosmic visuals, has made it one of Marvel's most enduring and influential properties, inspiring numerous adaptations across film, television, and animation.
