A review and a breakdown of the ending to ‘Monarch: Legacy of Monsters’ Season 2 Episode 7 Time travel twist, Titan X tracker, and Monsterverse impact. Visit!
The secrets of the Hollow Earth, its vast subterranean empire and the complex symbiotic relationships between human and giant monsters native to the planet itself are further explored in the series Monarch: Legacy of Monsters Episode 7 of Season 2. Tensions and relationships are shattered as the Monarchsquad is caught trying to cope with some shocking news.
The title “String Theory” refers to the idea that the past and the present are mysteriously intertwined at a fundamental level. That doesn’t stop this episode from building a strong sense of anticipation for a powerful finalé that will pack some punch visually, in action, and in emotional moments.
When Monarch: Legacy of Monsters season 2 aired in February 2026, we were all expecting some wild times. The bar? Higher, Godzilla was even being considered as a character option, and the shadows of Skull Island were bigger than ever. But I honestly don’t think any of us were ready for the MonsterVerse to do this kind of reality warping. Time dilation, okay, actual manipulation of the timeline in real time?
Let’s take a deep dive into the recap, review, and analysis of the final moments and this game-changing official ending and keep this your official spoiler alert. No need to go any further if you haven’t seen Legacy of Monsters episode 7!
To grasp the magnitude of String Theory, we have to talk about the chilling solitude of Axis Mundi. The episode begins by taking us back to 1962. Young Lee Shaw (Wyatt Russell, perfectly cast) and his Operation Hourglass team have come to this strange, unfriendly world.
The look of Axis Mundi is still as eerie and atmospheric as ever, but the meat and potatoes here is survival. Things go south fast. By day six, Lee is calling mission control in the blind, telling them he just buried Burke. Fast forward to day 15, and he’s realised what he’s got himself into. His rations are gone. His crew is dead. He is wholly, completely alone on a planet full of nightmare fuel — including a gigantic, hideous centipede that makes you want to look under your couch.
Wyatt Russell fully grounds these initial moments. You witness the moment the arrogant, assured military officer crumples into a person who knows he may never lay eyes on Hiroshi or Keiko again. It’s gritty, it’s emotional and it leads into absolute madness thereafter.
Then, the magic happens. At least that’s what Dr. Suzuki is doing with his experimental “Titan phone,” a phone that uses signals bounced off enormous Titans to track them. But rather than tuning in to a monster’s frequency, the radio picks up an old, ghostly signal from Operation Hourglass.
The radio crackles in the past. Young Lee wakes up, desperate, and answers. “Control, can you read me? “Over.”
On the other end of the line? Older Lee Shaw (portrayed by the legendary Kurt Russell). Let’s just stop and appreciate what the showrunners accomplished here. To have a real-life father and son portray the same character in different timelines was already a brilliant move in Legacy of Monsters Season 1.
But actually have them talk to each other — acting opposite themselves across decades? This is a monumental moment in television.
The exchange begins utterly tense. Young Lee gave his name and pleaded for an extraction, Older Lee stared at the radio in utter disbelief. For a moment, Old Lee makes a generic Monarch officer act, telling his younger self that they’re working on getting him home. But as the talk turns up, the mask falls.
It’s human, emotional, story telling and not just a gimmick. An older Lee has lived a life of regrets. He is well aware of the hell his younger self is going through, and Kurt Russell carries that heavy burden wonderfully. He’s hearing his own youth ful desperation, aware of the torturing decades of waiting that await him.

Now this is where Monarch: Legacy of Monsters goes full opposite on the MonsterVerse lore. We were aware time was altered in Axis Mundi, but in reality Legacy of Monsters episode 7 brings us a real time timeline, in which we can interact.
While young Lee is making his dangerous way through the lethal terrain of Axis Mundi, he is brutally slashed across the face. At that very moment in “the now,” Older Lee instantly gets an aged, weathered scar on his cheek—a scar that never existed in the series before that very moment.
This materialization of altered history proves the mind-boggling truth of their linked-ness: everything Young Lee does in 1962 ripples through timestreams, instantly rewriting the present. It’s the Butterfly Effect, but with Kaiju.
As the Older Lee reveals himself to Young Lee, the emotional floodgates open. Young Lee, understanding he is talking to his future self, immediately wants to know the unthinkable: Could he make things right? Could he save Keiko?
It’s probably the biggest tearjerker moment of the series yet. Wyatt Russell’s voice cracks with hope, as Kurt Russell’s eyes hold inescapable sadness. Older Lee tries vainly to talk him out of it. He understands that interference in the events around Keiko could cause a rip in their reality, that such a rip could erase the lives of the people they ultimately fought to protect. It’s a devastating awareness that even with the ability to alter the past some tragedies have to stay frozen in time for the good of the future.
So, if Keiko is beyond saving, what does that leave them to do with this miraculous connection? This leads us to the episode’s climax and ending, which serves as a teaser for the rest of Legacy of Monsters Season 2.
Older Lee shifts into tactical mode. He asks his younger self if he sights any MUTO activity. Young Lee mentions the horrifying centipede, and the creature that killed his crew. But Old Lee is hunting for one thing in particular. He asks if Godzilla is here. Young Lee hasn’t seen him.
Then, Old Lee recalls an important part of the puzzle: Godzilla wasn’t in that very quadrant of Axis Mundi in 1962, but Titan X was.
For the last few episodes of Legacy of Monsters Monarch has been badly hamstrung by not having a way to track this new, massive threat. But Old Lee realizes they have a literal time machine: a radio signal. If Young Lee can tag Titan X in the past, the tracker’s signal will reverberate through time, and that will lead Suzuki and Monarch to the beast’s location in the present.
Dr. Suzuki snatches the mic with lightning speed. In a beautifully tense, MacGyver-style sequence, he guides Young Lee as they strip the entry vehicle’s electronics for parts to fashion a basic, high-frequency tracking unit.
Legacy of Monsters episode 7 is a high-octane final sequence. Young Lee prowls the neon bathed, rainy landscape of Axis Mundi and at last comes eye to eye with the sheer, mind-boggling size of Titan X. In a bold move that exemplifies the character’s foolhardy courage, he gets the jury-rigged tracker onto the beast’s thick hide before disappearing.
Let’s break down why this matters so much for the overarching plot:
The Tactical Benefit: Legacy of Monsters Season 2 Titan X has been a ghost smashing things, but completely off the grid. By connecting the past with the present, Monarch can monitor the creature’s movements in real time. It’s the setup for a colossal showdown in the next episodes.
The Kong Connection: If you recall the teasers for Legacy of Monsters Season 2, we were treated to shots of a savage battle between Kong and Titan X. Now that Monarch can track the monster, they will likely try to bait it toward Skull Island or maybe Godzilla himself—and let the Titans duke it out.
The Rules of Time: The MonsterVerse has just unleashed Pandora’s Box. If a radio signal into the past can change appearances and monitor monsters, what else can it do? Could this technology fall into the wrong hands? Imagine APEX Cybernetics obtaining a “Titan phone” that can rewrite history. The possibility for future stories is endless.
The Tragedy of Lee Shaw: This is the Legacy of Monsters episode that really nailed Lee Shaw as one of the series’ most tragic leading men. He was required to consciously choose to not save the woman he loved for the sake of the timeline, even though he had saved the world (again). For the rest of the season, it’s Kurt Russell’s disbelieving character who is put through the most surreal ordeal by that choice.
“String Theory” is not only the best episode of Monarch: Legacy of Monsters Season 2, it might be among the best MonsterVerse media we’ve had to date. It was a perfect blend of high-concept, sci-fi, terrifying monster encounters and deep, character-driven emotional stakes.
Embracing the time-twisting conceits of Axis Mundi proved to be a sound creative choice, elevating the show beyond mere “monster of the week” procedural fare. The dynamic (and you can call it that) between Wyatt and Kurt Russell is the beating heart of the show and this episode makes full use of them both.
There are only three episodes left until the season ends, and all the pieces are on the board. We’ve got a tracker on Titan X, Godzilla is roaming the oceans, and Kong is standing by. The collision course is set; and if the rest of the episodes are as anywhere near as good as “String Theory,” then we’re going to have an unforgettable finale of Legacy of Monsters.

Monarch Season 2 reveals a shocking twist linking Monarch and Apex Cybernetics. Here’s how the Apple TV+ Monsterverse series changes the Godzilla timeline.
This isn’t simply another gigantic lizard tail crashing into a building. Monarch: Legacy of Monsters (if you’re keeping up withApple TV’s) has achieved the rarest of things: shifting the focus from “Big G” to the disastrous, trauma-ridden human beings left in his wake, all the while maintaining an 82% rating on Rotten Tomatoes.
But as we’ve been distracted by the trans-generational trauma of the Randa family and the effortless charisma of Kurt and Wyatt Russell as the same man, the showrunners have been orchestrating a much larger plan.
There’s a huge twist right under your nose, one that connects the “good guys” over at Monarch with the corporate bad actors we encounter later in the timeline. If you watch closely in the Monarch Season 2 opening, “Cause and Effect,” and the faint trail left all throughout the first season, it’s obvious: Monarch is not only tracking the Titans, they’re the creators of the very weapons designed to annihilate them.
Before we go down the rabbit hole, let’s discuss that 82% rating. In a season of franchise fatigue, Monarch triumphed by being human drama first and monster spectacle second. The show has been acclaimed by critics and fans for its dual-timeline story telling. We get the 1950s—the “Golden Age” of discovery with Bill Randa, Keiko, and Lee Shaw versus the 2015 post G-Day world. This apparatus does more than supply backstory, it facilitates a globe-trotting “Who Done It” mystery.
The high score is indicative of a series that treats its lore with respect. It doesn’t just throw a Kaiju at the screen to fix a boring scene, it creates tension based on the premise that the world we know isn’t the world that it really is.
The biggest surprise is not a new Titan (though “Titan X” is terrifying); it’s the discovery of just how deeply Apex Cybernetics has already infiltrated Monarch from within.
Apex Cybernetics needs no introduction to regular GoK fans as they are the corporate bad guys opposite Monarch in Godzilla vs. Kong—the ones who made Mechagodzilla out of a Ghidorah skull and a massive amount of hubris. In the films, they feel like a different, antagonistic group. But Monarch: Legacy of Monsters is completely changing that narrative.
Monarch Season 2 started off in the same way. Deputy Director Natalia Verdugo’s death by Titan X was not just a “shock death” for stakes. It created a power vacuum. When a leader in a secret organization dies, the one who comes into the light is usually a man with a secret intentions. And with Verdugo out of the way, that defines the line between Monarch’s “protect and study” mission and Apex’s “weaponize and destroy” mission blurring even more.
Remember Tim? The bottom-tier analyst who felt like the last “good guy” in the present-day Monarch? Season 1 ends with a bombshell: Tim is working with Apex.
This is the twist hiding in plain sight. We have been cheering on the “scrappy” Monarch team to reunite with their father and rescue the world, but the show has dropped whispers that the very organization we are following is bankrolling, staffing, — or maybe even being run by the future creators of Mechagodzilla.
The show takes us back to the Bikini Atoll nuclear ”test.” We see the horror of Bill and Keiko when they discover the military is not baiting Godzilla – they want to kill him.
The humanity factor within this is Lee Shaw’s complicity. He restrains Keiko and the bomb drops. This is the moment that plants the seed Monarch has always been a puppet for those with bigger guns and darker agendas. If Barris (the interim director) is in fact an Apex double agent, it recasts the past 60 years of Monsterverse history as a long-term R&D project for corporate warfare.
The show created Axis Mundi, a “sub-realm” that lies between this world and the Hollow Earth. It’s where time works differently, Keiko lived 50 years there but aged only a few weeks.
That the portal is a “leak” and not a door adds a fascinating wrinkle to the notion, suggesting an unregulated and possibly dangerous flow between planets.
Cate makes choices in Monarch Season 2 to resurrect a person who then inadvertently releases something tied into the series’ main message: humanity’s never-ending curiosity and greed usually comes with unintended consequences. The release of Titan X into the ocean is a reminder that we are out of our element, and that we are the real “monsters” in this tale.
The theory that Monarch and Apex could in fact be two branches of the same organization adds a far deeper layer to the entire Monsterverse. Monarch isn’t the “good science” and Apex isn’t the “evil corporation” — the twist implies that both organizations may be related in some way, if not from the start, then at least now by ideology. If that interpretation is true, it changes the story completely for the Monsterverse movies.
Cate and Kentaro, the Randa Kids, hunt for a father who deceived them, and get that their entire family fortune is based on a foundation of corporate espionage.
Lee Shaw: A lifelong “good guy” who turned out to be the enforcer for the bad guys all along.
The despair of Monarch: Legacy of Monsters is that the “Legacy” in the title isn’t focused on the monsters. It’s about the secrets we inherit, and how they grow up to crush us.
If Monarch: Legacy of Monsters was the origin of a secret in its first season, Monarch Season 2 is the industrialization of the Hollow Earth. Though the series is a “prequel” (set in 2017) to the neon-drenched chaos of Godzilla x Kong: The New Empire (set in 2027), it acts as the “secret history” that tells how a ragtag group of men with clipboards grew into a global powerhouse with gravity-defying jets and prosthetic Titan-gauntlets.
In The New Empire Monarch has beryllium carbide (B.E.A.S.T.) Glove-level tech (and more) gleaned from Apex Cybernetics research with which he now wraps Kong in the New Empire. Monarch Season 2 features the chaotic and unscrupulous beginning of the partnership.
The Brenda Connection: Brenda Holland (May’s former boss) is more than just a corporate bad guy — she is the connection. Monarch Season 2 reveals that her “animal testing” was in fact brain-based mapping at the onset for Titans.
The BEAST Precursor: Early Monarch/Apex models are shown, some designed to work with Titan biology. The exoskeleton tech Trapper wields in The New Empire wasn’t conjured from thin air; it was developed from the information Cate and Kentaro are now finding in 2017.
The New Empire submerges us in an underground Iwi village in a “hidden” layer of the Hollow Earth. Monarch Season 2 the physics of even making it.
The “Leak” Protocol: portals are stabilized in The New Empire. We get the “wild” form of these portals in Monarch Season 2. The Axis Mundi realm we learn about in the show is the hollow earth’s “waiting room.”
Time Dilation: The fact Keiko Miura (Cate’s grandmother) is still young is what allows the Monarch to eventually establish stable outposts. They go on to ‘tune’ the frequency of these rifts to not take the time-slip that caused the near erasure of Keiko and Lee Shaw from history.
One of the highlights of The New Empire is Trapper, the Titan vet. Monarch Season 2 teases this career path.
From “Fear” to “Upkeep”: the mid-century surges Bill and Keiko honored pedophile Titans as gods to fear and obey. In the 2017 timeline, the transformation takes place. We have Monarch (and Apex) realizing that if they can’t kill Godzilla, they have to “manage” him.
The Medical Shift : The sea creature Titan X and the “Sea Scarabs” in Monarch Season 2 necessitate that Monarch introduces the very biological containment and field-based medical work Dr. Ilene Andrews and Trapper depend on ten years hence.
The Monarch Season 2 premiere finds us on Skull Island, and Kong is now front and center. This is what links Kong: Skull Island (1973) and Godzilla vs. Kong (2024).
The Apex Base: We see Apex already firmly established on the island by 2017 in the series. This is how they came to construct the huge “dome” habitat that we see in later movies. They weren’t just hanging out and waiting for the next rental unit to be turned over; they were there, hiding in the jungle, pilfering Monarch’s observations for years.
