Thor is Donald Blake. He is a superhero.
He is a doctor, who on a trip to Scandinavia, found Mjolnir, the magical Norse hammer. When he picked it up, he transformed into Thor, the Norse God of Thunder. Now, whenever trouble arises, he taps his cane in the ground and becomes Thor.
He is a member of the superhero group the Avengers.
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, the character is physically the strongest of the Norse gods, and has performed such feats as almost lifting the entire World Serpent (stated to encircle 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” (“berserksgangr” in Norse), which will temporarily increase his strength tenfold. The character also possesses virtually inexhaustible godly stamina, high resistance to physical injury such as rocket fire and falls from orbital heights and superhuman speed, agility and reflexes. As the Norse god of Thunder, Thor can summon the elements of the storm (lightning; rain; wind; snow) and uses Mjolnir as a tool to focus this ability. As the son of the Earth goddess Gaea, Thor has some control over the Earth, allowing him to create country spanning chasms.[volume & issue needed]
The character is a superb hand-to-hand combatant, and 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.
After Odin’s death, Thor inherited his father’s power, the Odinforce. Thor becomes capable of feats such as reconstructing the Earth’s Moon, willing the Asgardian monster Mangog into nothingness and, by focusing his entire power into a hammer throw, decapitating a Desak-occupied Destroyer. Thor also acquires mastery of the Runes, and a level of enlightenment that allows him to free Asgard from the eternal cycle of Ragnarok.
As Donald Blake he is a highly trained and licensed physician and surgeon.
When Mjolnir was damaged, the Odinforce was transferred by Doctor Strange from Thor to the hammer, as the power was required to restore it.
