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.
Like all Asgardians, Thor is not truly immortal but relies upon periodic consumption of the Golden Apples of Idunn to sustain his lifespan, which to date has lasted many millennia. Being the son of Odin and the elder goddess Gaea, Thor is the physically strongest of the Norse gods, and has performed such feats as lifting a large percentage of the World Serpent, stated to be one third the size of the Earth, and hurling the Odinsword, an enormous mystical blade of incalculable weight, through a Celestial. If pressed in battle, Thor is also capable of entering into a state known as the "Warrior's Madness" ("bärsärkargång" in Norse), which is claimed to temporarily increase his strength tenfold. He also possesses virtually inexhaustible godly stamina, high resistance to physical injury (eg. rocket fire, falls from orbital heights), immunity to all Earthly diseases, and superhuman agility and reflexes. As the God of Thunder, Thor can summon the elements of the storm (lightning,rain,wind,etc.) but uses Mjolnir as a tool to focus this ability.With millenia of experience, Thor is a superb hand-to-hand combatant. He is also skilled in armed combat, excelling in the use of the war hammer, sword and mace. Thor possesses two items which assist him in combat: the enchanted Belt of Strength, and his mystical hammer Mjolnir. The first item doubles Thor's strength and endurance while the second is used to control his weather abilities; flight, energy projection and absorption; dimensional apertures; matter manipulation and the most powerful of his offensives, the God Blast and the Anti-Force
