Thor (often called The Mighty Thor) is a Marvel Comics superhero, based on the thunder god of Norse mythology. The superhero was created by editor Stan Lee and penciller Jack Kirby, who co-plotted, and scripter Larry Lieber, and first appeared in Journey into Mystery #83 (Aug. 1962).
On a mission from his father, the omnipotent Lord of Asgard, Odin, Thor acted as a superhero while maintaining the secret identity of Dr. Donald Blake, an American physician with a partially disabled leg. Blake would transform by tapping his walking stick on the ground; the cane became the magical hammer Mjolnir and Blake transformed into Thor.
Thor often battled his evil adoptive brother Loki, a Marvel character adapted from the Norse god of mischief, and was a member of the superhero group the Avengers. Apart from this superhero Marvel featured a number of Thors (and similar characters) based on him.
