Thor's father Odin decided his son needed to be taught humility and consequently placed Thor (without memories of godhood) into the body and memories of an existing, partially disabled human medical student, Donald Blake. After becoming a doctor and on vacation in Norway, Blake witnessed the arrival of an alien scouting party. Blake fled into a cave after they heard him and began to pursue him. After discovering Thor's disguised hammer Mjolnir, and striking it against a rock, he transformed into the thunder god.

Defeating the aliens, Thor shared a double life with his alter ego: treating the ill in a private practice with nurse - and eventual love - Jane Foster and defending humanity from evil. Thor's presence on Earth almost immediately attracted the attention of his adoptive brother and arch-foe Loki, who returned repeatedly to Earth in a bid to destroy Thor. Loki was also responsible for the emergence of three of Thor's principal foes: the Absorbing Man, the Wrecker, and the Destroyer. On one occasion, Loki's tactics were accidentally beneficial - although successful in using an illusion of the Hulk to draw Thor into battle, it resulted in the formation of the superhero team the Avengers, of which Thor was a founding and longstanding member.

Thor's other early foes included the Red Army, Zarrko, the Tomorrow Man, the Radioactive Man, the Lava Man, the Cobra, Mister Hyde, the Enchantress, the Executioner, and the Grey Gargoyle.

Falling in love with Jane Foster, Thor disobeyed his father and refused to return to Asgard, an act for which he was punished on several occasions. Thor's natural affinity for Earth was eventually revealed to be due to the fact that he was the son of the Elder Goddess Gaea. Although Thor initially regarded himself as a "superhero" like his teammates in the Avengers, Loki's machinations drew Thor into increasingly epic adventures, such as teaming with father Odin and Asgardian ally Balder against fire demon Surtur and Skagg the Storm Giant, and defeating an increasingly powerful Absorbing Man and proving his innocence in the "Trial of the Gods". This necessitates an extended leave of absence from the Avengers.

Thor also encountered Greek God Hercules, who became a loyal friend. Thor also saved Hercules from fellow Olympian Pluto; stopped the advance of Ego the Living Planet; rescued Jane Foster from the High Evolutionary and defeated his flawed creation, the Man-Beast. Odin finally relented and allowed Thor to love Jane Foster, on the proviso she pass a trial. Foster, however, panicked and Thor intervened. Although Foster failed the test, Odin returned her to Earth where she was given another chance at love, while a heartbroken Thor was introduced to Asgardian warrior Sif. Thor battled the Asgardian troll Ulik for the first time when he attempted to steal Mjolnir; defeated Avengers foe Kang the Conqueror and the alien Super-Skrull and with Odin and his Asgardian allies engaged in a battle to the death with the Enchanters Three.

Despite repeated attempts by Loki to destroy Thor with a series of past and new foes, Thor was victorious, and even avoids being claimed by Asgardian death goddess Hela. The thunder god returned to Asgard to prevent Mangog from drawing the Odinsword and ending the universe learned the origin of the cosmic entity Galactus (and encountered Ego once again) and stopped the child-like Him (who would eventually become Adam Warlock) from kidnapping Sif.
