Thor Fact — November 1, 2026

Today's Fact

Every god needs a tax identity. Thor's came with a Brooklyn address, a construction job, and the least convincing eyewear in comics.

THOR'S SECOND SECRET IDENTITY WAS A BROOKLYN CONSTRUCTION WORKER NAMED SIGURD JARLSON — DISGUISED BY A PONYTAIL AND A PAIR OF GLASSES!

The Featured Fact

When the Donald Blake identity ceased to exist, Thor still needed somewhere to live on Earth that was not a throne room. In Thor #341 (1984), written and drawn by Walt Simonson, he walks into S.H.I.E.L.D. headquarters and asks Nick Fury to build him a new civilian life from scratch.

Half an hour of spy-agency tailoring later, the God of Thunder emerges in jeans and a T-shirt, hair pulled back in a ponytail, answering to Sigurd Jarlson. Fury, worried the physique still gives him away, adds the finishing touch — an ordinary pair of glasses — then tests the disguise at a press conference, where Thor bumps into a mild-mannered reporter named Clark who almost recognises him, then thinks better of it.

Jarlson reports for work on a Manhattan construction site under foreman Jerry Sapristi, and the identity's first shift lasts minutes: a scream, a falling girl, a toppling crane, and then the dragon Fafnir arriving to prove that no disguise survives contact with Asgard's enemies. The name endured anyway — four decades later, The Mortal Thor #1 (2025) revived Sigurd Jarlson as Thor's mortal identity once more.

Why It's Obscure

Donald Blake gets the documentaries. Sigurd Jarlson gets a lunch pail, a foreman, and a forty-year wait for his comeback.

Why a new name

Blake was gone for good — With the physician identity revealed as a construct and erased, Thor needs papers, a job, and an address like any other immigrant to New York.

The disguise

Glasses. That is the disguise. — Simonson plays the oldest joke in superheroics completely straight: ponytail, denim, spectacles — and a certain reporter from another publisher nearly falls for it.

First shift

Crane rescue, then a dragon — Jarlson's debut ends with Thor striking Mjolnir to the ground mid-rescue, trading the work shirt for the raiment of the Thunderer in front of his new crew.

The revival

2025 brings him back — Al Ewing's Mortal Thor reborn the god as amnesiac construction worker Sigurd Jarlson, hard hat and work hammer, with the 1984 identity as its direct foundation.
