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, Odin, Thor acts as a superhero while maintaining the secret identity of Dr. Donald Blake, an American physician with a partially disabled leg. Blake can transform by tapping his walking stick on the ground; the cane becomes the magical hammer Mjolnir and Blake transforms into Thor.
Thor, a founding member of the superhero group the Avengers, often battles his evil adoptive brother Loki, a Marvel character adapted from the Norse god of mischief. He is among Marvel's most powerful superheroes. Many recurring characters in his stories are based on Norse Mythology. Apart from this main superhero, Marvel features a number of characters based on him.
Chris Hemsworth portrays Thor in films set within Marvel Studios' cinematic universe, first appearing in the 2011 film Thor. Hemsworth reprised his role for 2012's The Avengers and returned again in Thor: The Dark World (2013).
The mighty Thor is Asgard's finest and bravest warrior. With god-like strength, command over lighting, and the aid of the legendary hammer Mjolnir, Thor defends Earth alongside his battle-worthy companions, the Avengers.
