I’m Not Saying Netflix Should Nuke Buenos Aires, But The Eternaut Season 2 Might

Lose Weight

I wasn’t prepared for The Eternaut Season 2 to crawl into my brain like a mind-controlled clone with trust issues. But here I am, spiraling through Reddit threads, TikTok theories, and Buenos Aires conspiracies while Netflix plays coy about the release date. The finale left me wrecked, staring at Clara with a mix of fear and "what even is real?" Season 2 hasn’t been officially unleashed yet, but between leaks, comic callbacks, and Stagnaro’s cryptic vibes, I’m all in. When is The Eternaut Season 2 coming out? Honestly, I need answers—and maybe therapy.

Season 1 Wrecked Me. The Eternaut Season 2 Might Just Finish What the Snow Started

Netflix’s Argentine sci-fi hit “El Eternauta” (aka The Eternaut) only just unleashed its first season’s six episodes – and fans are already scouring every interview, finale frame, and Reddit thread for hints of a follow-up. Season 1 ends on a jaw-dropping cliffhanger involving mind-controlled loved ones and ominous alien forces, practically begging for a Season 2. So, will Netflix answer the call? Below we break down everything we know (and everything die-hards are speculating) about The Eternaut – Season 2: from official renewal news and rumored release dates to wild fan theories about clones, time travel, and the fate of Juan Salvo’s family. Buckle up, because the post-apocalyptic buzz is real.

Renewal Status – Netflix’s Plans & Official Word

Netflix has been playing it a bit coy with formal press releases, but the writing is on the wall (and in interviews): The Eternaut will return. In fact, Netflix’s VP of Latin American content, Francisco “Paco” Ramos, let slip on premiere day that Season 2 is a done deal – “Sí, hay segunda temporada. Porque la historia lo requiere, básicamente” (“Yes, there is a second season. Because the story basically requires it”). That’s as official as it gets. The first season only dropped on April 30, 2025, yet Ramos confirmed to Argentine newspaper La Capital that the story will continue, even if he wouldn’t divulge when filming starts or any premiere date. Lead actor Ricardo Darín (who plays everyman hero Juan Salvo) echoed that confidence, teasing “we still have the second part of The Eternaut ahead of us” and “I believe we’re going to aim higher!”. In other words, the cast and crew are already mentally gearing up for more cosmic mayhem. Initially, some outlets cautiously noted that Netflix was likely waiting to gauge viewership before greenlighting more​. But given the show’s quick climb into Netflix’s Top 10 and massive local buzz, it appears Netflix quietly gave a pre-release greenlight. According to Forbes and other sources, the renewal was approved even before Season 1 debuted, reflecting Netflix’s high confidence in this ambitious Argentine saga​. There’s been zero talk of cancellation – quite the opposite – and even Argentine production company K&S Films and director Bruno Stagnaro have hinted since day one that they envisioned a multi-part epic. Bottom line: Season 2 is officially happening, and Netflix is all-in on El Eternauta as a new flagship franchise.

Rumor Mill: Early Greenlights, Release Date Whispers & Episode Count

The early renewal news set off a flurry of speculation about when we’ll actually see Season 2. Don’t expect a quick turnaround – this isn’t a series you can bang out in a few months. Multiple industry sources (and even Netflix insiders) suggest that Season 2 won’t land until at least 2026 or 2027​. Why so long? For one, The Eternaut is one of the most expensive productions in Argentina’s history – roughly $15 million per season​ – with extensive post-production, VFX, and elaborate sets. Writing and pre-production for the next chapter will be “a long and careful process” with no filming start date announced yet​. In fact, Netflix’s Ramos hinted they’re committed to doing it right, not fast, emphasizing the “strong commitment” to Latin American sci-fi and an intent to make El Eternauta a benchmark franchise​. Many outlets concur that 2027 is a safe bet for Season 2’s premiere, factoring in script development, shooting, and all that CGI alien goodness​. This might test fans’ patience, but hey – the timeline literally involves time travel (more on that later), so a bit of a wait feels on-brand.

What about the episode count and format? Season 1 contained six episodes, each packed with tension. Rumors in fan communities speculate that the creators may have originally envisioned a 10–12 episode arc for the story, potentially splitting it into two seasons. In fact, some Reddit sleuths claim 12 episodes were shot, with Netflix slicing the narrative into two halves – meaning Season 2 could also have six episodes (the back six) if that theory holds. While unconfirmed, it’s notable that Season 1’s finale felt like a true midpoint rather than a conclusion. It could be coincidence, or it could mean the next season is already conceptually mapped out. There’s also talk of “fichajes de altura” – high-profile additions to the cast – in Season 2​, implying we might see some new characters (perhaps a big-name actor as the next villain or a key ally). Netflix hasn’t dropped any teaser or trailer yet (way too early), but given the buzz, don’t be surprised if by late 2026 we start seeing cryptic teasers snowing down on social media.

Season 1’s Cliffhanger Ending – How It Sets Up Season 2

If you’ve seen the Season 1 finale, you know The Eternaut left us with more questions than answers – very deliberately. The show’s creators clearly constructed the last episode to demand continuation. Let’s recap the essentials (spoilers ahead for Season 1’s ending): Juan Salvo and the survivor crew thought they’d found safety at a military base (Campo de Mayo) broadcasting rescue messages, only to realize it’s a trap orchestrated by the aliens. By the final scenes, we learn the invaders have a horrifying ability: they can clone and mentally control humans, using them as foot soldiers. Beloved characters start acting very strange. Juan’s best friend Lucas turns on the group under alien influence, even confessing a cryptic betrayal before dying​. A final attack forces our heroes to flee as a horde of human clones and controlled survivors swarm them​. The gut-punch reveal? Juan’s daughter, Clara, has been cloned and appears as a brainwashed shooter among the alien forces​. Seeing his little girl step out as a cold-eyed rifle-toting pawn of the enemy absolutely wrecks Juan – and viewers. It’s an emotional cliffhanger of epic proportions.

Season 1 doesn’t resolve much at all; it essentially stops at the moment Juan realizes the scope of the threat: the real enemy might be wearing familiar faces. The narrative is intentionally not conclusive – as one press review noted, it “da la sensación de que todavía queda mucho por pasar” (“it gives the sense that there’s still a lot left to happen”). Indeed! We’re left with Juan and a handful of allies on the run, vowing to regroup and fight back. The finale also slipped in a trippy sequence where Juan hallucinates a mural full of symbolic imagery – hints of an “eternal cycle” or time loop that he feels he’s lived through before​. Eagle-eyed fans caught references to a bucle temporal (time loop) and other surreal clues in that scene, strongly suggesting larger sci-fi shenanigans to come. In short, Season 1’s ending sets the table for Season 2 by:

  • Introducing the idea that the aliens are not just killing humans but controlling and replicating them. Now anyone could be an enemy in disguise. Trust issues will run high at the safe camp.
  • Putting Clara/Carla (Juan’s daughter) in peril as a mind-controlled clone, creating a deeply personal stake for Juan in Season 2 – can he save her or will he be forced to see her as an enemy?
  • Showing Juan and his comrade Franco (one of the survivors) planning to search for missing friends like Inga and “Grandote” (who were separated in the chaos)​. But ominously, the odds of those friends still being unturned humans are slim.
  • Revealing that the much-touted safe haven (Campo de Mayo base) is compromised – likely surrounded by alien infiltrators posing as survivors​. Season 2 might start with a dramatic reckoning at that camp (imagine an invasion from within).
  • Teasing the broader alien strategy at play: luring humanity’s survivors into false sanctuaries (via radio messages) only to trap or convert them. That radio call urging people to come to the camp? It needs to be shut down ASAP in Season 2, or humanity is toast​.

All these threads practically scream for resolution. Season 2 will have to address the elephant in the room: Is the real Clara dead or somehow retrievable from alien control? Can Juan bring himself to fight his own daughter’s clone? And who – or what – is ultimately behind this invasion?

Fan Theories Run Wild: Mind-Controlled Clones, Time Loops & Other Wild Speculation

With such an open-ended finale, fan theorists are having a field day. Social media and forums are rife with discussions dissecting every plot point for clues about Season 2’s direction. Here are the hottest theories and expectations fueling the fandom:

  • “Invasion of the Body Snatchers” in Buenos Aires: The introduction of mind-controlled clones has fans convinced Season 2 will be a paranoid thriller where any character could secretly be an alien pawn. Viewers point out the eerie behavior of several characters in late Season 1 – not just Clara, but also Lucas and even random survivors – suggesting a widespread infiltration. One Spanish commentary notes “el uso de clones controlados mentalmente” as a key element and metaphor (alien forces literally alienating people from themselves)​. In Season 2, expect Juan’s group to grapple with identifying who is real and who’s a clone. Trust will be in short supply. Some fans even speculate that the real Clara might still be out there and the one we saw is just a duplicate – setting up a possible rescue or heart-wrenching confrontation between Juan and two Claras!
  • The Time Travel Twist: A prevailing theory (especially among those familiar with the original 1950s comic) is that the series is heading toward a time-bending narrative. The “eternal” in The Eternaut isn’t just poetic; it hints that Juan Salvo becomes an “eternal traveler.” In the graphic novel’s later chapters, Juan winds up caught in a temporal loop – reliving the invasion over and over until he finds a way to break the cycle. Season 1 planted seeds for this: Juan’s hallucinations of strange symbols and his déjà vu sense of having done this all before​ are likely foreshadowing that time travel or timeline resets are coming. This aligns with the comic’s ending where Juan is thrown into a pocket universe and eventually travels back in time to before the invasion. Radio Times even pointed out that Juan’s “visions” in the show’s finale are actually memories of a future he’s already lived – trippy!. Fans are hyped at the prospect that Season 2 (or a potential Season 3) could delve into this full Looper-meets-Groundhog Day scenario, possibly showing Juan trying to alter fate to save his family. Will we see Juan literally become “el eternauta,” drifting through time to stop the invasion at its source? Many are crossing their fingers.
  • Bigger, Badder Aliens Ahead: In Season 1 we mostly saw two types of aliens – the deadly glowing snowflakes (which turned out to be a chemical/bio-weapon) and the insect-like creatures that enforce the ground invasion. But the finale briefly shows a silhouette of something (or someone) clearly calling the shots – an alien with an unsettling number of fingers, dubbed “The Hand” in the comics. Fans fully expect Season 2 to introduce the alien hierarchy: the Hands (high-level controllers) and their masters, known only as “Them” in the comic lore. Essentially, the bugs are foot soldiers too, controlled by the Hand, who in turn serve an even more powerful entity. The Eternaut could expand its sci-fi world-building by revealing these higher-tier aliens and their endgame. There’s also buzz about the “Gurbos” – monstrous beasts from the graphic novel that might make it on-screen. In the source material, the aliens eventually unleash giant monsters (Gurbos) to decimate the Argentine army. If Bruno Stagnaro stays somewhat faithful, we might witness an absolutely bonkers sequence in Season 2 where a military counterattack gets squashed (literally) by these creatures. Fans are simultaneously terrified and excited at the thought of Kaiju-sized threats stomping through Buenos Aires.
  • Nuclear Option and Worldwide Stakes: Another likely Season 2 plot point (again drawn from Oesterheld’s story) is the escalation of the war beyond Argentina. In the comic, things get so dire that international forces decide to nuke Buenos Aires to stop the aliens, forcing Juan’s team to make a narrow escape. Viewers are speculating whether the Netflix series will go that far. The groundwork is there: Season 1 already showed Buenos Aires in utter chaos and an alien occupation spreading. If the invaders keep luring survivors to camps, it stands to reason the rest of the world might intervene drastically. Imagine the drama of Juan racing against time (literally) to blow up the alien’s dome shield and evacuate before a nuke hits. It would be a bold, dark turn – exactly the kind of high-stakes spectacle a Season 2 could deliver on Netflix. Fan forums have even discussed the possibility of seeing a devastated post-nuclear landscape or Juan’s horror at watching his city destroyed as part of the story’s climax. It’s heavy stuff, but The Eternaut has never been afraid of mixing the intimate with the apocalyptic.
  • Juan vs. Clara – An Ethical Showdown: Perhaps the most emotional theory revolves around Juan’s impending choice: save his daughter or save humanity. Season 1’s final moment (Juan closing his eyes in pain as he understands Clara’s condition) sets up a tragic dilemma. If Season 2 forces Juan to confront clone-Clara in battle, what will he do? Some predict a storyline where Juan tries desperately to deprogram or free Clara from alien control – possibly at great cost. Others think the show might go even darker, with Juan having to kill the clone of his own child if she can’t be turned back. A Spanish fan commentary teased that the series promises an “conflicto ético de proporciones épicas” – an ethical conflict of epic proportions – if Juan must choose between Carla (Clara) or humanity​. Grab the tissues, because whichever way it goes, that confrontation will be gut-wrenching. Knowing Bruno Stagnaro’s grounded storytelling, we can expect Season 2 to really drill into the psychological toll on Juan as he fights not just aliens, but the very people he’s trying to protect.

The theory mill is churning at full tilt. Mind-controlled clones? Check. Time loops? Likely. Alien overlords and nukes? Very possible. The show’s fanbase – from Reddit to TikTok – is keeping the conversation alive with bold predictions. One thing everyone agrees on: The Eternaut Season 2 has all the ingredients to be bigger, bolder, and even more brain-bending than the first chapter.

Who’s Coming Back (and New Faces We Might See) in Season 2

It wouldn’t be The Eternaut without Ricardo Darín front and center, so you can bet your last empanada that he’ll reprise Juan Salvo in Season 2 – Netflix isn’t letting go of Argentina’s biggest star. Likewise, Carla Peterson (Elena, Juan’s ex-wife), César Troncoso (Favalli, the science-minded friend), and Andrea Pietra (Favalli’s wife Ana) should all return, assuming their characters survived the finale (Favalli did; another friend, Polsky, unfortunately bit it earlier). Mora Fisz, who plays young Clara Salvo, will obviously be crucial – though in what form (the real Clara, the clone Clara, or both) remains to be seen. We might see her stretching some creepy acting chops as an emotionless alien drone if clone-Clara gets more screen time. Ariel Staltari’s character Omar, an original addition in the show, made it through Season 1 and serves as a sort of audience surrogate, so he’s likely to be back providing commentary (if he survives the clone purge at Campo de Mayo!). Essentially, any character who wasn’t explicitly killed on screen in Season 1 has a decent chance of popping up again – and given the clone twist, even death might not be the end (the enemy could always whip up a copy).

As for new characters, this is where things get exciting. The mention of “fichajes de altura” (top-tier cast additions) by Spanish outlets​ has fans speculating on who could join the party. Two big roles from the comics could debut in Season 2: the Leader/Hand alien, which might involve a performer (or voice) to personify the intelligent alien boss, and possibly Professor Moscato, a character from the comic’s later part who helps Juan (though Favalli in the series kind of covers that brainy role already). There’s also chatter about whether the show will introduce Héctor Oesterheld himself as a meta-character – in the comic, the author Oesterheld wrote himself in as a character who meets Juan. If the time-travel arc comes in, Juan could encounter an author figure or someone in the past, which would be a mind-blowing homage. Fan casting fantasies range from notable Argentine actors to even international cameos (because if Netflix is going big, why not rope in a familiar face for a villain?). One fun fan theory imagines Peter Lanzani (from Argentina, 1985) or another Argentine star playing a heroic military leader in the resistance, only to be revealed as another clone – a short but juicy role.

For now, Netflix remains mum on casting. But given the success, don’t be surprised if Season 2 attracts even bigger names. The show’s high profile might lure Latin American or Spanish actors who want to be part of this cultural phenomenon. In any case, Season 2 will likely expand the cast of characters as the story’s scope widens beyond the original group huddled in Juan’s house. And yes, we expect plenty of creepy, nameless clone troopers and alien creatures – likely portrayed by stunt actors and enhanced with CGI – essentially a whole new “cast” of monsters to terrorize our heroes.

Buenos Aires as a Character: Filming Location & Argentine Soul in Season 2

One of the standout elements of The Eternaut is how authentically Argentine it feels. The producers turned Buenos Aires into a sci-fi battleground while keeping its cultural heartbeat strong, and Season 2 should continue that trend. The first season was filmed on location in Buenos Aires – over 35 real city locations were used, from quiet residential streets to recognizable landmarks, all covered in eerie volcanic ash-like snow. Additionally, the team built more than 25 virtual sets using cutting-edge LED Volume technology to recreate neighborhoods under alien siege. This blend of real and virtual will no doubt carry into Season 2, possibly at an even grander scale. If the story follows the characters beyond the city (say, to government bunkers or into the aliens’ base), we might see new settings. But Buenos Aires is still the core – even if a nuclear bomb is in its future on-screen, the city’s presence looms large. Fans have joked that “Buenos Aires itself deserves a casting credit” for how vividly it’s portrayed, from the cobblestone streets of its barrios to the hauntingly empty 9 de Julio Avenue in the blackout.

Moreover, The Eternaut has never shied away from Argentina’s political and historical echoes. Season 1 was loaded with allegory: the notion of neighbors betraying neighbors under alien mind-control has strong parallels to the country’s military dictatorship era (where citizens were disappeared and some collaborated with the regime)​. The show even made a point to update Juan Salvo’s backstory – making him an ex–Malvinas War veteran – to add a layer of Argentine history to his character​. Expect Season 2 to continue weaving these themes. The choice of Campo de Mayo as the refuge that turns into a trap is chillingly on-the-nose; Campo de Mayo was a notorious real-life military base used during the Dirty War. In the series, it becomes the site of a duplicitous promise of safety. This intersection of sci-fi with national trauma and memory gives The Eternaut a depth that fans deeply appreciate. There’s buzz that Season 2 might further explore the idea of a “collective hero” (a core theme of the comic and series) – how ordinary people band together in crises – while also warning about the dangers of authoritarian “saviors” (the military or authorities in the show are not to be blindly trusted). In an interview, Bruno Stagnaro emphasized the story’s humanist and anti-totalitarian spirit, noting it’s about “gente normal” (normal people) surviving and that the heroism is collective, not individual​. That ethos will persist.

Filming-wise, local reports hint that Netflix will keep production in Argentina for Season 2 to maintain authenticity (and because moving a $15M+ Argentine series elsewhere makes no sense). This means more work for local crews and perhaps even opportunities for Argentine fans to catch a glimpse of filming once it gears up – though probably under heavy secrecy given the spoilers at stake. The cultural atmosphere in Argentina around El Eternauta is intense: the original comic is a beloved classic, often read as a parable about resistance to oppression. Season 1’s release was met with nationwide excitement, and even some poignant street art – for instance, activists in Buenos Aires plastered images from the Dirty War over an Eternaut billboard to draw parallels between the fictional alien occupation and real historical oppression​. Season 2 will land into that same cultural conversation. It’s likely to further engage with the country’s psyche – perhaps commenting on unity vs. division, memory (time loop as metaphor for “never again” to past atrocities?), and Argentina’s place in a global fight (if world governments get involved in the plot). In short, the show’s sci-fi action always comes with substance, and the unique flavor of Buenos Aires – its slang, its skyline, its history – will continue to set The Eternaut apart from any other apocalyptic series.

The Road Ahead: Anticipation and What Fans Can Expect

With all these pieces on the board, The Eternaut Season 2 is shaping up to be an epic continuation that could blow the scope wide open. Think high-stakes survival war meets mind-bending time paradoxes, all grounded by the emotional core of a father trying to save his family. Netflix has a potential global phenomenon in the making – the show already resonated beyond Argentina, tapping into universal themes of solidarity and endurance. If Season 2 sticks the landing, The Eternaut could join the likes of Dark or Stranger Things as a binge-worthy sci-fi saga with a passionate worldwide following (and plenty of think-pieces dissecting its deeper meaning).

For now, fans will have to content themselves with theory-crafting and rewatching Season 1’s clues. Keep an eye on official Netflix channels and events like TUDUM in 2025 and 2026 for sneak peeks – any teaser will instantly become headline news in the entertainment world. In the meantime, the legacy of Oesterheld’s comic provides a rough roadmap, but Bruno Stagnaro and his writers have shown they’re not afraid to remix timelines and introduce new twists. One thing’s for sure: nobody is surviving Season 2 alone – as the tagline says, “nadie se salva solo.” Juan Salvo will need allies old and new to take on an enemy that literally wears human faces. The collective hero will be tested like never before.

So stock up on your waterproof coats and gas masks, porque la nevada mortal no ha terminado – the deadly snow isn’t done falling yet. Season 2 of The Eternaut promises to pick up right where the storm left off, delivering answers to longtime questions (hello, time travel?) and surely posing new ones. Until then, fans will be counting the days and keeping the Eternauta flame alive in forums and fan art. The eternal traveler’s journey is far from over – nos vemos en la próxima nevada (see you at the next snowfall)!
