Thor Has A New Identity In Marvel Lore, But There's A Catch

Warning! Major spoilers for the finale issue of Immortal Thor ahead!As Marvel’s Thor begins a major new era, the hero has gained a “new” secret identity: Sigurd Jarlson. However, like many aspects of Thor’s storyline over the past several years, this is actually the resurrection of a deep-cut alter ego that the Mighty Thor briefly adopted back in the 1980s.
Immortal Thor #25, written by Al Ewing, with art by Jan Bazaldua, Justin Greenwood, and Pasqual Ferry, is the final issue of Marvel’s most stellar ongoing series in recent memory.
The issue follows the long-heralded death of Thor, sending him on a brief but memorable journey into the afterlife, before he is reborn as a mortal, under the name Sigurd Jarlson.

“Sigurd Jarlson” first appeared, as an updated alter-ego for Thor, in 1983’s Thor #341, written and illustrated by Walt Simonson. The hero adopted this new human identity after abandoning his original persona of “Donald Blake.” This is echoed in the plot of Immortal Thor #25, the crux of which involves Thor battling the embittered remnants of Blake in the afterlife.

Marvel has teased Thor’s death for some time now, but it still managed to be a shock when it finally happened, pulling off the rare “obvious twist.”
Readers went into Immortal Thor #25 knowing that it would end with Thor’s return, but the issue still managed to pleasantly surprise readers, as author Al Ewing has become known for, by making Thor’s first human identity the “final boss” of the run, before transitioning to an entirely new paradigm in which he operates under his second identity, that of Jarlson.
As has been the case with Immortal Thor all along, the final issue remixes and reinterprets classic Thor mythology from throughout the character’s Marvel history, while setting the stage for the next “act” in the hero’s current journey to do more of the same. Notably, the inclusion of Thor’s Jarlson alter-ego might hint at what comes next.

More than just killing off Thor, the conclusion of Immortal Thor writes him out of Marvel continuity entirely, so his rebirth as a mortal, Sigurd Jarlson, brings him into a world where his heroic alter-ego never existed, setting up a strange, but highly engaging dynamic for the upcoming sequel series, aptly titled Mortal Thor.
The use of Sigurd Jarlson as Thor’s new human identity suggests that fans should go back to Marvel’s Thor comics from the 1980s.
While Immortal Thor drew inspiration from all of Thor lore, it paid particularly close attention to the hero’s 1970s stories; the use of Sigurd Jarlson as Thor’s new human identity suggests that fans should go back to Marvel’s Thor comics from the 1980s in order to get a glimpse of what Al Ewing has in store for readers.
Immortal Thor #25 is available now from Marvel Comics.
