“Sigurd Jarlson” first appeared, as an updated alter-ego for Thor, in 1983’sThor#341, written and illustrated by Walt Simonson. The hero adopted this new human identity after abandoning hisoriginal persona of “Donald Blake.“This is echoed in the plot ofImmortal Thor#25, the crux of which involves Thor battling the embittered remnants of Blake in the afterlife.
Readers went intoImmortal 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 withImmortal Thorall along, the final issueremixes and reinterprets classicThormythologyfrom 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, theinclusion of Thor’s Jarlson alter-ego might hint at what comes next.
