You're rowing through the Lake of Nine, the water is eerily still, and then the entire landscape starts to move. That massive, moss-covered mountain you were looking at? It’s not a mountain. It’s a scale. God of War Jormungandr is, without a doubt, one of the most visually arresting things Sony Santa Monica has ever put on a screen. But if you’ve played through the 2018 reboot and God of War Ragnarök, you know that Jormungandr isn't just there for scale or "cool factor." He’s a walking (or slithering) temporal paradox that breaks the rules of the game's universe.
Honestly, he's kind of the emotional anchor for the whole Norse saga, even if he mostly just grunts in a language that literally shakes the earth.
He’s massive. He’s ancient. And according to the lore Mimir spills while you're paddling around, he’s actually from the future. It’s weird to think about, right? Most players see a giant snake and think "boss fight," but Jormungandr ends up being your weirdest, most loyal ally. He recognizes Atreus. He hates the Aesir. And he has a grudge against Thor that spans across linear time itself.
Where did God of War Jormungandr actually come from?
The game drops a huge lore bomb early on: Jormungandr and Thor have already fought, but that fight hasn't happened yet for us. Confused? You should be. During the events of Ragnarök—the actual end-of-the-world event, not just the game title—Thor hits Jormungandr so hard that he splinters the Yggdrasil, the World Tree. This impact literally sends the snake back in time to a period long before his own birth.
That’s why, when you first meet him in the 2018 game, he’s already "The World Serpent." He’s been sitting in that lake for ages, just waiting for the timeline to catch up with him. He’s a transplant. A temporal refugee.
But the real kicker is the "Ironwood" sequence in God of War Ragnarök. We see Atreus—who we know is actually Loki—taking a giant, soulless snake and stuffing the soul of a Giant into it. That’s the "birth" of Jormungandr. So, the snake you see in the lake is the older, grizzled version of the soul Atreus saved in the past. It's a closed loop. It’s high-concept sci-fi hidden inside a gritty fantasy game about a dad with anger issues.
The Thor Grudge
If you look closely at the statue of Thor in the Lake of Nine, the one the Serpent eats? That’s not just a random act of vandalism. It’s personal.
In Norse mythology, and specifically in the version Santa Monica Studio crafted, Jormungandr and Thor are destined to kill each other. In the 2018 game, Jormungandr is basically a grumpy old man who’s already lost a fight to Thor and is just waiting for the rematch. When he sees Kratos and Atreus, he doesn't see "enemies." He sees the catalysts that will lead to Thor’s eventual downfall. He helps you because your goals align: making life miserable for Odin and his golden boy.
Why his size matters for the gameplay loop
Scale in video games is usually a trick. It's skyboxes and clever camera angles. But with God of War Jormungandr, the developers had to make him feel like a physical part of the world.
Think about the Lake of Nine. As the water level drops throughout the game, more of the Serpent's body is revealed. This isn't just a visual flex; it’s the primary mechanic for world-building. His body literally defines the boundaries of the map. When he moves, the world changes. You can’t go to certain areas until he shifts his coils. It’s a brilliant way to turn a character into a level design tool.
The "Inside the Belly" mission is probably the best example of this. You’re literally sailing into his throat to find a lost eye. It’s gross, it’s damp, and it emphasizes just how gargantuan this creature is. If Kratos is a god, Jormungandr is a force of nature. Even the "God of War" looks like an ant compared to a single tooth of the Serpent.
The Language of the Ancients
The sound design for the Serpent deserves a mention. It’s not just "monster noises." Bear McCreary and the audio team used low-frequency throat singing and actual tectonic-style rumbles to create his voice. When Mimir "speaks" to him, it feels like a diplomatic negotiation between a man and a hurricane.
There’s a specific detail most people miss: the Serpent tells Mimir that Atreus "looks familiar." Since we know Jormungandr is from the future, he’s actually recognizing his own "father" or creator. It’s a subtle bit of foreshadowing that pays off massively in the sequel. It also explains why a creature that could easily crush Kratos’s boat chooses to be so helpful. He’s helping his dad. Sorta.
Ragnarök and the Final Stand
When the final battle in God of War Ragnarök kicks off, you finally see the "past" version of Jormungandr—the one Atreus just created—take on Thor.
It’s chaotic.
The sky is literally tearing apart. You see the Serpent and Thor clashing in the background while you fight on the ground. This is the moment where the time-travel loop completes. Thor lands that legendary blow, the screen flashes with the white light of the World Tree splintering, and the Serpent vanishes. He’s gone. He’s been sent back to the start of the 2018 game.
It’s one of the few times a game has used "Time Travel" without making it feel like a cheap plot device. It feels earned because we spent two games living with the "result" of that fight before we ever saw the fight itself.
The "Two Snakes" Problem
Some fans get confused about whether there are two snakes.
Basically, yes. During the final battle, the "Big" Jormungandr (the one from the lake) isn't the one fighting Thor. It’s the "Young" Jormungandr that Atreus grew in Jotunheim. The older version, the one we’ve known since 2018, is presumably somewhere else or simply faded out as the cycle renewed. It’s a bit "wibbly-wobbly timey-wimey," as another famous franchise would say, but the internal logic holds up if you don't overthink the physics of soul-transference.
How to appreciate Jormungandr more on your next playthrough
If you’re going back through the series, pay attention to these specific things. They change how you view the World Serpent entirely.
- The Eye Reflecting: Look at the Serpent’s eyes when he talks to Atreus. There’s a strange, almost sad recognition there. He’s looking at a version of his creator that hasn’t even realized his power yet.
- The Mimir Conversations: Listen to the bits of dialogue Mimir translates. Jormungandr mentions the "loss of the Giants" frequently. He’s a lonely survivor of a genocide, waiting for the one person who can bring his race back—even if only in spirit.
- The Scale of the Body: Look at the mountains in the distance in Midgard. Many of those "peaks" are actually just the Serpent’s back. It’s easy to forget he’s wrapped around the entire world.
- The Call of the Horn: In the 2018 game, someone calls the Serpent while Kratos is carrying a sick Atreus to Freya. The game never explicitly confirms who did it. Most theories point to a time-traveling Kratos or Loki, but the mystery adds to the Serpent's mythological weight. He’s the keeper of secrets.
Actionable Insights for Lore Hunters
If you want to dive deeper into the Norse mythology that inspired the game, there are a few things you should do to see where Santa Monica Studio stayed true to the myths and where they took creative liberties.
Read the Poetic Edda. In the original myths, Jormungandr is the child of Loki and the giantess Angrboda. The game keeps this "lineage" but makes it metaphorical/spiritual rather than biological. In the myths, the Serpent is much more of a straightforward "monster," whereas the game makes him a tragic, wise figure.
Compare the Thor Fight. The "Völuspá" (an old Norse poem) describes the final battle where Thor kills the serpent but only takes nine steps before falling dead from the venom. In the game, the outcome is different to allow the Kratos/Thor narrative to play out, but the "nine steps" imagery is often referenced in the game's armor sets and item descriptions.
Visit the Shrines. Don't skip the Jotnar Shrines (the wooden triptychs). They give you the "prophecy" version of the Serpent's life. Comparing what the Giants predicted to what Kratos actually did shows how the game is all about breaking fate. Jormungandr is a living example of fate being rewritten through the lens of time travel.
The World Serpent isn't just a mascot. He represents the overarching theme of the Norse saga: the complicated, often messy relationship between parents and children. He is the son of a boy who hasn't grown up yet, protecting a grandfather who doesn't know him, in a world that fears him. That’s a lot of narrative weight for a giant snake to carry, but God of War Jormungandr does it with ease.
