While employing a mortal guise, Thor will transform back into his mortal form should he be separated from Mjolnir for more than 60 seconds.
By spinning Mjolnir in a circle, Thor can open portals to other dimensions.
Formerly, it also allowed him to travel in time, but Immortus removed this power.
Mjolnir is virtually unbreakable, and allows Thor to command the powers of the storm, causing rain, thunder and lightning.Thor can channel the storm’s fury into devastating blasts of energy that can destroy even secondary Adamantium.He can also channel his godly energies through Mjolnir into blasts so powerful that they can slay even immortals.Mjolnir can absorb other energies into itself, which Thor can then release.Mjolnir obeys Thor’s commands as though it were alive, and if Thor’s will is strong enough, the hammer can pass through nearly any barrier to reach him should he so desire.
Using this command over Mjolnir’s flight path, Thor is able to use the hammer to fly, achieving escape velocities.Mjolnir can also transform Thor into his civilian guises.When Thor is a civilian, the hammer most often becomes an old wooden cane.Universe Marvel Universe Real Name Thor Odinson Aliases Donald M.Blake, God of Thunder, Son of Odin, the Thunderer, Lord of Asgard, Jake Olson, Sigurd Jarlson, Donar, Donner, Hloriddi, Unhappy Hrungnir’s Playmate, Veur, Hrodr’s Foe-Man, Longbeard’s Son, Vingthor the Hurler, Siegfried, Siegmund, "Woe-King"; impersonated Hercules, Harokin, Freya; formerly bound to Eric Masterson Identity(As Donald Blake) secret Citizenship Asgard; honorary US citizen Place of Birth A cave in Norway First Appearance Venus #12 (1951); (modern) Journey into Mystery #83 (1962) Origin Journey into Mystery #83 (1962), Thor #159 (1968), Thor Annual #11 (1983) As Blake, found Mjolnir in Norway, became Thor (Journey into Mystery #83, 1962); founded the Avengers (Avengers #1, 1963); learned origin of Donald Blake identity (Thor #159, 1968), origin an past adventures on Earth recounted (Thor Annual #11, 1983); adopted Sigurd Jarlson identity (Thor #341, 1984); merged with Eric Masterson (Thor #408, 1989); exiled for killing Loki (Thor #432, 1991); retrieved from exile by Eric Masterson (Thor #457, 1993); became insane, overcame with aid of Adam Warlock and Dr.Strange (Thor #460-471, 1993-1994); adopted form of Jake Olson (Thor #2, 2001); witnessed death of Odin, became Lord of Asgard (Thor #41-43, 2002) had falling out with Avengers (Avengers #63, 2003); Asgard bombed (Thor #68, 2003); conquered Earth (Thor #68, 2003); undid conquest of Earth (Thor #79, 2004); perished in battling Those Who Sit Above In Shadow (Thor #85, 2004)Odin Borson (father, deceased), Gaea (mother), Frigga (adoptive mother), Loki (adoptive brother, deceased), Balder, Hermod, Tyr, Vidar (half-brothers), Buri (Tiwaz, paternal great-grandfather), Bolthorn (maternal great grandfather), Bor Burison (grandfather, deceased), Bestia (paternal grandmother, presumed deceased), Vili, Ve (paternal uncles, deceased), Sigyn (sister-in-law), Solveig (sister-in-law, deceased), Jormungand (Midgard Serpent), Fenris Wolf (nephews), Hela (niece), large extended family via Gaea and others As the son of Odin and Gaea, Thor's strength, endurance and resistance to injury are greater than the vast majority of his superhuman race.
