During the 2008 “Secret Invasion” storyline, Thor rescues and heals Beta Ray Bill, who after being temporarily given Mjolnir, aids Thor in defending Earth against an invading force of alien Skrulls. Due to Loki’s deception, Thor battles and kills his grandfather Bor, and is banished from Asgard. With Thor’s hammer Mjolnir damaged in that battle, Thor seeks out Doctor Strange, who is only able to repair the hammer by transferring the Odinforce from Thor to Mjolnir, binding the two in a symbiotic relationship. With the repaired hammer, Thor is able to draw out the imprisoned Sif, and return her to her own body, thereby restoring Loki to his male body in the process.
In January, 2009, Thor V3 reverted to issue #600, reflecting the total number of published issues from all three volumes.

To coincide with the Thor film, Marvel launched a number of new series starring the character in mid-2010. These included Thor: The Mighty Avenger, Thor: First Thunder,Thor: For Asgard and Iron Man/Thor. In April 2011, Thor once again reverted to its original title of Journey into Mystery with issue #622, reuniting writer Gillen and artist Braithwaite in a series of stories starring Thor’s adopted brother, Loki. An ongoing series, titled The Mighty Thor, launched the same month with writer Fraction and artist Coipel. The series ended with issue #22 in October 2012.
In October 2014, a fourth volume of Thor by Jason Aaron and artist Russell Dauterman debuted that featured a female character (later revealed to be Jane Foster) in the role of Thor after the classic hero is no longer able to wield Mjolnir. Aaron stated that “this is not She-Thor. This is not Lady Thor. This is not Thorita. This is Thor. This is the Thor of the Marvel Universe. But it’s unlike any Thor we’ve ever seen before.” The following October, Aaron and Dauterman signed an exclusive agreement with Marvel to continue their work together in a second volume of The Mighty Thor, also starring Foster.
