Thor Midgard Serpent Issue

What Is the Thor Midgard Serpent Issue?

The Thor Midgard Serpent issue refers to storylines where Thor faces off against Jormungandr, the world serpent from Norse mythology. These encounters have appeared across multiple comic runs, but certain issues stand out as essential reading.

Marvel has published several iconic Thor vs. Midgard Serpent battles. The most famous appears in Journey Into Mystery #85 from 1962, the first appearance of both characters. But the relationship between god and serpent runs deeper than a simple fight.

The mythology behind these stories is straightforward: Odin fathered Thor and Jormungandr with the giantess Angrboða. They were born as siblings. The serpent hates Thor. Thor hates the serpent. They'll kill each other at Ragnarok. Everything else is just backstory.

Key Storylines You Need to Read

Journey Into Mystery #85 (1962)

Stan Lee and Jack Kirby created the modern version of this clash here. Thor, disguised as Donald Blake, discovers the Midgard Serpent terrorizing a fishing village. The fight is brief and brutal—the serpent wins this round. Thor barely escapes.

This issue matters because it established the dynamic that Marvel would use for decades: Thor cannot defeat the world serpent. Every encounter ends the same way.

Thor #274-275 (1978)

Roy Thomas and Walt Simonson revisited the battle during the "The Serpent's Teeth" storyline. This is where Simonson started building his legendary Thor run. The fight is longer, more brutal, and sets up threads that would dominate his tenure.

Thor #337-341 (1984)

Walt Simonson's masterpiece. The World Serpent storyline sees Thor journey to the realm of the Midgard Serpent. This is where the mythology gets weird. Thor meets his future self. Time breaks. The serpent isn't just a monster—it's a force of entropy.

Simonson understood something most writers miss: the Midgard Serpent isn't a villain. It's an inevitability. Thor can't win because the fight isn't about victory. It's about delay.

Thor (2020) #20

Donny Cates and Nic Klein brought the serpent back in the current era. This storyline connects to the larger cosmic horror elements Cates was building. The serpent has grown. Thor has changed. The stakes are different now.

Comparing the Major Thor vs. Midgard Serpent Encounters

Why the Serpent Always Wins

Here's the bitter truth about these stories: Thor cannot kill the Midgard Serpent. Not because he's weak, but because the mythology won't allow it.

At Ragnarok, Thor and Jormungandr will kill each other. That's the prophecy. Writers who understand Norse mythology work within those constraints. The question isn't "will Thor win?" It's "how long can Thor hold out?"

Simonson used this brilliantly. His Thor isn't weak for losing. He's tragic. He knows the outcome. He fights anyway. That's the point.

How to Read These Issues

If you want the full experience, here's the reading order:

• Start with Journey Into Mystery #85 for context
• Jump to Thor #274-275 to see the setup
• Read Thor #337-341 for the definitive story
• Finish with Thor (2020) #20 for the modern take

You can find these in trade paperback collections. The Simonson run is collected in Thor: The World Serpent. The newer issues are readily available digitally on Marvel Unlimited.

What Makes These Issues Worth Reading

The best Thor/Midgard Serpent stories aren't about action. They're about inevitability. Thor knows he can't win. He fights anyway. The serpent knows they'll kill each other at Ragnarok. It waits anyway.

That's compelling tragedy. Not because someone fails, but because success is impossible and they continue regardless.

Skip the issues where the serpent is just a generic monster. The good ones treat it as a cosmic force. Find those stories.
