Mobile Suit Gundam GQuuuuuuX (Sieg Axis) — Complete Guide | Story, Mobile Suits & Ending Explained

“What If Char Had Stolen the Gundam?” — The Biggest “What If” in 45 Years of Gundam History

On January 17, 2025, the theatrical premiere of GQuuuuuuX -Beginning- began — and the first thing audiences saw on screen was a Gundam painted red.

The RX-78-2 Gundam, born 45 years ago as a white mobile suit — now red. That single visual was enough to tell everyone: this is not an ordinary Gundam show.

Mobile Suit Gundam GQuuuuuuX (Sieg Axis) is the newest entry in the Gundam franchise, born from a historic first collaboration between Sunrise (Bandai Namco Filmworks), the creator of the Gundam series, and Studio Khara, the studio behind Evangelion. It is directed by Kazuya Tsurumaki, who served as assistant director on Evangelion: 3.0+1.0 Thrice Upon a Time. The screenplay is co-written by Yoji Enokido (Diebuster) and Hideaki Anno.

“The Gundam studio” and “the Evangelion studio” joining forces — a combination that anime fans never even dared dream of. The resulting chemistry sparked intense debate among fans, while the theatrical film alone grossed 3.52 billion yen with 2.139 million admissions — a massive hit.

Whether you love it or hate it, one thing is undeniable: this is a show that demands to be talked about.

Whether you know Gundam inside and out or have never seen a single episode, this article will tell you everything about Sieg Axis. The first half is spoiler-free, giving you everything you need to decide whether to watch. The second half contains full spoilers, with a complete breakdown of the story.

The choice of Kenshi Yonezu for the OP theme and VTuber Hoshimachi Suisei for the ED theme also signals that this series was designed to reach far beyond the traditional Gundam fanbase. Music composer Shiro Sagisu is best known for scoring the Evangelion series — further cementing the strong Khara DNA in the creative lineup.

The World of GQuuuuuuX — What Is “A World Where Zeon Won”?

No Gundam Knowledge Required — A Quick Overview of the Setting

Before you dive into GQuuuuuuX, there is one piece of background you need to know — just a tiny bit about the original Mobile Suit Gundam (1979), which aired 45 years ago.

In the original Gundam, humanity has expanded into space. A conflict breaks out between the space-dwelling Principality of Zeon and the Earth Federation. The protagonist, Amuro Ray, pilots the white Gundam and fights for the Federation, which ultimately wins the war. That is the “canonical history.”

The world of Sieg Axis is a parallel world where history diverged from that canonical timeline.

What changed? Char Aznable (Zeon’s ace pilot) stole the Gundam and repainted it red. As a result, the Principality of Zeon won the One Year War, and the Earth Federation was driven into complete retreat.

“A single divergence” fundamentally changed the entire world of Gundam. This is the greatest premise — and the greatest trick — of GQuuuuuuX.

The Power Map — The World of Universal Century 0085

The balance of power in UC 0085, the year in which the story takes place, looks completely different from the canonical timeline.

Faction	Position	Overview
Principality of Zeon	Ruling power	Won the One Year War. Supreme Leader Gihren Zabi rules, but internal power struggles are intensifying
Earth Federation	Defeated side	Effectively in complete retreat. Resistance organizations operate underground
Side 6 (Izuma Colony)	Nominally neutral	The main setting of the story. Effectively under Zeon’s influence
Clan Battle Scene	Illegal	Underground mobile suit betting matches. Both youth entertainment and a funding source for the underworld

The world after Zeon’s victory appears peaceful on the surface, but is in reality filled with oppression and surveillance. The young people of Izuma Colony channeling their energy into illegal Clan Battles is portrayed as a form of rebellion against this suffocating society.

Clan Battle (Claba) — Life-or-Death Underground Combat

A major element driving the early and middle portions of the series is “Clan Battle” (abbreviated as “Claba”). In simple terms, it is an illegal 2-on-2 mobile suit fighting circuit.

• Format: 2v2 team battles using mobile suits (called “MAV battles”)
• Location: Space around Side 6
• Victory condition: Destroy the opponent’s mobile suit head to win
• Broadcast: Matches are guerrilla-streamed online, and are also subject to betting
• Popularity: A hugely popular form of entertainment, especially among Side 6’s youth

Although the “destroy the head to win” rule provides a nominal safety measure, the reality is quite rough. Attacks fly at torsos, limbs, and everything in between, and cockpits getting caught in the crossfire is not uncommon. Pilots can be injured or even killed. Ostensibly a “sport,” in practice it is a life-or-death fight.

Clan Battle also functions as a modern rearrangement of the original Gundam’s “Newtype battles.” The tension of one-on-one duels, the sensation of pilots “connecting” through their machines — combined with an e-sports-style viewing culture — proved to be an effective hook for younger audiences.

Main Character Introductions (Spoiler-Free)

This section introduces the basic appeal of each character without touching on the core mysteries (identities, fates, etc.).

Amate Yuzuriha (Machu) — The Girl Who Chooses to “Respond”

Name	Amate Yuzuriha
Voice Actor	Tomoyo Kurosawa
Age	High school student
Entry Name	Machu
Mobile Suit	GQuuuuuuX (Sieg Axis)

A high school girl living in Side 6’s Izuma Colony. Smart, with friends — seemingly an “ordinary girl.” But beneath the surface, a vague sense that there is something “phony” about this world has been smoldering inside her.

Through a twist of fate, she becomes the pilot of the GQuuuuuuX and rises through the ranks of Clan Battle. The typical Gundam protagonist is “a boy drawn into battle,” but Amate is a girl who chooses to “respond” to the world of her own free will.

Tomoyo Kurosawa’s performance — from the naturalism of everyday conversations to screams in battle to moving monologues — was highly praised for breathing life into the character of Amate.

Shuji Ito — The Enigmatic Second Pilot

Name	Shuji Ito
Voice Actor	Shimba Tsuchiya
Mobile Suit	Red Gundam
Trait	Paints “Kirakira” graffiti on the colony exterior walls

A mysterious boy who paints graffiti on the colony’s outer walls. Quiet and elusive, nobody can tell what he is thinking. He is the pilot of the Red Gundam and enters Clan Battle as Machu’s “MAV (partner).”

“Fight, the Gundam is telling me” (「戦え、とガンダムが言っている」) — this line, which defines Shuji, became the series’ most iconic quote and was even printed on t-shirts. Whether he is being “ridden” by the Gundam or riding it of his own will — that ambiguity creates a unique tension throughout the story.

Nyaan — A War Refugee Girl with a Harsh Past

Name	Nyaan
Voice Actor	Yui Ishikawa
Background	War refugee
Mobile Suit	GFreD

A girl who survived harsh conditions as a war refugee. She operates as an illegal courier in the underworld, and is the very person who pulled Amate into the world of Clan Battle. Cat-like in agility with razor-sharp instincts, her survival skills are second to none among the cast.

Though Nyaan has lived a life diametrically opposed to Amate’s, a mysterious bond forms between them. Yui Ishikawa’s performance masterfully captured the “fragility behind the bravado,” earning deep empathy from viewers.

Challia Bull — A Minor Character from the Original, Elevated to a Major Role

Name	Challia Bull
Voice Actor	Shinji Kawada
Rank	Zeon Colonel
Alias	The Man Who Returned from Jupiter

In the original Gundam, Challia Bull was a Newtype soldier who appeared in only a few episodes. In the GQ world, he is one of the most important characters driving the plot. Officially, he commands the mission to search for Char, but his true motives run far deeper.

Giving Challia Bull — a character who was “wasted” with an early exit in the original — a full role was a major surprise for longtime fans. Shinji Kawada’s calm, low-toned voice perfectly conveyed “the intelligence that seems to see through everything” alongside “the humanity that still hesitates.”

Annqi — Underworld Businesswoman and Team Mother

Name	Annqi
Voice Actor	Mariya Ise
Title	President, Kaneban Ltd.

A Zeon-born woman who runs “Kaneban Ltd.,” a junk shop on Izuma Colony. She is the sponsor of the Pomeranians (Machu’s team) and serves as a “team mother” figure. Tough but caring, strict about money but absolutely unwilling to sell out her comrades.

Haro — An Autonomous AI Brought to Life by Rie Kugimiya

Name	Haro
Voice Actor	Rie Kugimiya
Type	Autonomous AI Robot

Haro, the iconic spherical robot of the Gundam franchise, serves as Amate’s companion aboard the GQuuuuuuX in the GQ world. Every time Rie Kugimiya’s adorable voice shouts “Haro! Haro!”, it provides a brief moment of comfort amid the heavy developments.

But Haro in the GQ world is more than a mascot. It also serves as the interface connecting the GQuuuuuuX’s Omega Psycommu system to Amate, and its importance grows as the story progresses.

Additional Main Cast

Character	Voice Actor	Overview
Haro	Rie Kugimiya	Autonomous AI robot. Amate’s companion aboard the GQuuuuuuX
Char Aznable	Yuuki Shin	Zeon’s hero, “The Red Comet.” Missing since the Zeknova Incident
Gihren Zabi	Koichi Yamadera	Supreme Leader of the Principality of Zeon. Iron-fisted ruler
Kycilia Zabi	Kaori Nazuka	Commander of Zeon’s Assault Mobile Corps
Ramba Ral	Hiroo Sasaki	Survived in the GQ world. Promoted to Lieutenant
Xavier Olivette	Seiichiro Yamashita	Top graduate of the Flanagan Institute, an elite soldier
Komori Harcourt	Akane Fujita	Top graduate of the officer academy
Shiiko Sugai	Manami Hanawa	“The Witch” — shot down over 100 units during the One Year War
Sayla Mass	—	Char’s sister. Earth Federation MS pilot
Lalah Sune	Keiko Han / Hina Yomiya	A Newtype deeply connected to Char
Dr. Flanagan	Hiroshi Shirokuma	A leading authority on Newtype research
Jezzi	Yukitoshi Tokumoto	Pomeranians’ mechanic
Nabu	Shoya Chiba	Clan Battle play-by-play commentator
Kaine	Yusuke Nagano	Clan Battle color commentator

Mobile Suits & Mecha — Classic Machines Reborn in “What If” Designs

One of GQuuuuuuX‘s greatest appeals is that iconic mobile suits from the original Gundam appear redesigned under the premise “What if Zeon had won?” Mechanical designer Ikuto Yamashita preserved the familiar silhouettes while reimagining them with his own interpretation, creating a freshness that feels genuinely new.

Mobile Suit	Faction	Pilot	Features
GQuuuuuuX (Sieg Axis)	Zeon	Amate (Machu)	The protagonist’s unit. Equipped with the Omega Psycommu
Red Gundam	Zeon (originally Federation)	Shuji	The RX-78-2 captured by Char and repainted red
Gelgoog (GQ)	Zeon	Sugai / Bocata / Xavier	Zeon’s main mass-produced unit
Police Zaku	Side 6 Military Police	Araga, others	Zaku customized for law enforcement
Rick Dom (GQ)	Zeon	Gaia / Ortega / Challia	Features a transformation gimmick to high-mobility mode
Light Cannon	Civilian	Sugai, others	A civilian mobile suit used in Clan Battle
GFreD	—	Nyaan	Nyaan’s mobile suit. Active from the mid-series onward
Hambrabi (GQ)	—	—	The GQ world’s version of the Hambrabi
Zaku (GQ) / Char’s Zaku (GQ)	Zeon	— / Char	Zaku variants in the GQ world
White Gundam (RX-78-02)	Earth Federation	—	Appears close to the canonical tri-color scheme. A machine that “should not exist” in the GQ world
Sharon’s Rose	—	—	A mobile armor closely tied to the Zeknova Incident

Of particular note is the design of the protagonist’s unit, the GQuuuuuuX. Its distinctive leg shape, unlike any previous Gundam-type mobile suit, and the glowing Omega Psycommu embedded in its chest boldly depart from the “Gundam design language.” Designer Ikuto Yamashita has stated that he “aimed for a design somewhere between Evangelion Unit-01 and a Gundam,” making the visual fusion of both franchises’ DNA immediately apparent.

The Red Gundam, being canonically the RX-78-2 repainted red by Char, retains a silhouette faithful to the original while creating an entirely different impression through its color scheme alone. The visual impact of “a Gundam that should be white, but is red” is an elegant design choice that communicates the GQ world’s premise at a glance.

Production Background — How the Historic Sunrise × Studio Khara Partnership Came to Be

It Started with a Single Phone Call in 2018

The planning for Sieg Axis dates back to 2018. Naohiro Ogata, a producer at Sunrise (Bandai Namco Filmworks), called Yuki Sugitani, a producer at Studio Khara. “Once Evangelion is finished, would you consider making a Gundam at Khara?” — that was how it all began.

Sugitani brought the idea to director Kazuya Tsurumaki. Tsurumaki’s first impression was that it was “an enormously heavy responsibility.” However, driven partly by a desire to repay Sugitani — who had endured years of hard work as a production desk manager — he decided to submit a proposal.

The Bold Gamble of “A World Where Zeon Won”

What Sunrise hoped to get from Khara was “an adventurous concept that would be difficult to produce internally.” A bold vision that only an outside creator could bring — that was the starting point of Sieg Axis.

The concept Tsurumaki submitted was “depicting a world where Zeon won the One Year War.” Initially, Sunrise had envisioned an Alternate Universe Gundam (a standalone world), so the proposal of a Universal Century “what if” was a surprise. But the appeal of Tsurumaki’s vision won them over, and the project was approved.

Hideaki Anno’s “Unshackled” Involvement

The One Year War portion (the “Beginning” section) was originally conceived as a short pre-title sequence. However, the sheer volume of information made it too large for a TV timeslot, and it was spun off into a standalone theatrical film.

Hideaki Anno was entrusted with the screenplay for the Beginning section. When Anno delivered a script depicting Char Aznable piloting the Red Gundam into battle, director Tsurumaki was struck with admiration: “This is a script only Anno could have written.”

According to Tsurumaki, Anno had become “unshackled” after completing the Evangelion series. The otaku passion that had fueled works like Gunbuster and Nadia came roaring back, and Anno poured out a massive volume of plot material in a short span. Anno freely playing in the sandbox of Gundam — “someone else’s creation” — echoed his amateur days, when he made parodies of Gundam and Ultraman as a student filmmaker.

The Beginning Theatrical Film — The Shock of 3.52 Billion Yen at the Box Office

The theatrical premiere GQuuuuuuX -Beginning- opened on January 17, 2025. In its first three days, it grossed 598 million yen with 352,000 admissions, claiming the #1 spot in the weekend box office rankings.

The momentum only continued, with the second week posting an extraordinary 107.6% increase over the first. After 66 days in theaters, it had crossed 3.29 billion yen with 2 million admissions, ultimately reaching a total of 3.52 billion yen and 2.139 million admissions — the second-highest-grossing Gundam theatrical release of all time.

Period	Box Office Revenue	Admissions
First 3 days	598 million yen	352,000
First 10 days	1.43 billion yen	856,000
66 days	3.29 billion yen	2,000,000
73 days	3.34 billion yen	2,020,000
Final total	3.52 billion yen	2,139,000

These numbers mean that Sieg Axis captured an audience far beyond traditional Gundam fans — drawing in Evangelion fans, Kenshi Yonezu fans, Hoshimachi Suisei fans, and even people who do not normally watch anime. A re-release in late June 2025 also performed well, meeting the “I want to see it on the big screen again” demand that arose after the TV series concluded.

Reception & Response — Among the Most Divisive Works in Gundam History

What Fans Praised

• “A visual revolution”: The chemistry between Studio Khara and Sunrise produced visuals unlike anything in previous Gundam. The psychedelic “Kirakira” sequences were particularly breathtaking
• “The ultimate gateway to the original”: A phenomenon emerged where young viewers who watched Sieg Axis began watching the original Gundam — a “rediscovery of First Gundam by a new generation”
• “Pure celebration energy”: Homages to iconic scenes and lines from the original Gundam came in waves, creating a unique sensation of “I don’t fully get it, but I totally get it!”
• “The return of legendary voice actors”: The finale featured Shuichi Ikeda (the original Char), Toru Furuya (Amuro), and Keiko Han (Lalah)
• “The power of the music”: Kenshi Yonezu’s “Plazma” and Hoshimachi Suisei’s “Mou Dou Natte mo Ii ya” were highly acclaimed as standalone tracks

What Fans Criticized

• “Not enough respect for the original”: Some longtime fans strongly objected to the bold alterations to the original’s settings and characters
• “The story is hard to follow”: The emotion-first, logic-second approach did not work for all viewers. Some called it “carried entirely by vibes”
• “12 episodes is not enough”: The scope was too ambitious for 12 episodes. Many felt the second half in particular was rushed
• “Too happy an ending”: Viewers expecting the bittersweet conclusions typical of Gundam found the finale’s brightness unsatisfying

Director Tsurumaki’s Answer — “I Prioritized Emotion Over Logic”

Director Kazuya Tsurumaki has openly stated that he “prioritized emotion over logic.” With the intention of “reaching a generation that doesn’t know the appeal of the original Gundam,” he deliberately drove the story through accessible, clear emotion.

After the finale aired, Hideaki Anno praised the team: “It was twelve episodes of TV condensed with passion, obsession, and determination.” After Episode 11, he commented with undisguised excitement: “Those guys actually did it!!”

One thing is certain: this was a show that made everyone want to say something about it. Perhaps it is happier for a work to spark heated debate than to be met with silence.

Sieg Axis continued to generate discussion on social media even after the broadcast ended, with analysis videos, fan art, and fan works being actively produced. After the finale, the show dominated trending topics on X (formerly Twitter) for hours, with terms like “Gundam,” “Machu,” “Shuji,” and “Last Shooting” filling the rankings. For a Gundam series to maintain this level of conversation not just during its run but long after it ended is rare.

Viewing Guide — Should You Watch the TV Series or the Film First?

The Relationship Between the TV Series and the Film

Sieg Axis exists in two versions: the 12-episode TV series and the theatrical premiere film Beginning. The film presents the One Year War portion (the flashback arc) in full before moving to Machu’s story, with some structural and directorial differences from the TV series.

	TV Series (12 episodes)	Theatrical Film: Beginning
Runtime	Approx. 5 hours (24 min × 12 episodes)	Approx. 2 hours
One Year War Section	Inserted as fragments across episodes	Presented in full at the start
Advantage	Allows you to follow character emotions in detail	Lets you grasp the world-building all at once through visuals
Best for	Viewers unfamiliar with the original Gundam	Viewers who know the original Gundam

The verdict: If you have not seen the original Gundam, start with the TV series. If you know it, start with the film. Fans of the original will immediately realize “this world is different from canon!” during the film’s opening, making it easier to get immersed. Newcomers will find the TV series’ more gradual structure easier to follow.

Film-First Plan (approx. 7 hours): Start with the theatrical film Beginning (approx. 2 hours) to establish the setting, then watch all 12 TV episodes (approx. 5 hours). The luxury course for original Gundam fans.

Complete Conquest Plan (approx. 12 hours): Watch the original Gundam movie trilogy (approx. 7 hours) first, then tackle Sieg Axis. Knowing the “source material” multiplies the emotional impact many times over. It takes time, but provides the most fulfilling experience.

After You Finish Sieg Axis

If Sieg Axis makes you want to know more about the “source material,” your next step should be the original Mobile Suit Gundam. The movie trilogy lets you grasp the entire story in about 7 hours. When you discover who Char, Ramba Ral, Gaia and Ortega, and Lalah “really are” — your impression of Sieg Axis will shift to yet another level.

Gunpla Guide — Complete Kit List and How to Choose

The Sieg Axis Gunpla lineup launched alongside the theatrical premiere, centered on the HG series. Ikuto Yamashita’s mechanical designs, clearly distinct from previous Gundam aesthetics, offer a fresh building experience.

Hambrabi (GQ)	HG 1/144	2,860 yen	June 2026 (scheduled)

Your First Sieg Axis Gunpla — What Should You Buy?

If in doubt, start with the “HG GQuuuuuuX.” It is the protagonist’s unit, affordably priced at 2,200 yen, and lets you appreciate Ikuto Yamashita’s distinctive leg design. If you want a second kit, go for the “HG Red Gundam” — the visual impact of “a Gundam that should be white, but is red” makes it a display showpiece on its own.

For experienced modelers, the “HG Rick Dom — Gaia’s / Ortega’s Unit” is the most interesting from a gimmick standpoint, featuring a no-parts-swap transformation to high-mobility mode, plus an electromagnetic harpoon with a lead wire — a kit full of thoughtful details.

If you want to hold the heart of the story in your hands, choose the “HG GQuuuuuuX Endymion Unit Awakened.” This kit recreates the form from the final battle and is the definitive symbol of the series’ climax.

Music — The “Auditory Experience” Created by Kenshi Yonezu × Hoshimachi Suisei × Shiro Sagisu

OP Theme “Plazma” — Kenshi Yonezu

The OP theme “Plazma” made headlines as Kenshi Yonezu’s first contribution to the Gundam franchise. Set to a driving beat, the song’s theme of “resonance with the world” feels like a musical expression of the relationship between Amate and the GQuuuuuuX. The music video surpassed 20 million views within one week of release, making it a major hit as a standalone track.

ED Theme “Mou Dou Natte mo Ii ya” — Hoshimachi Suisei

The announcement that VTuber Hoshimachi Suisei would perform the ED theme for a Gundam series generated enormous buzz. “Mou Dou Natte mo Ii ya” is a ballad that gently embraces Amate’s “emotion-first” way of living. Playing at the end of each episode, it left viewers with a lingering sense of “the beauty of acting on emotion.”

Hoshimachi Suisei is an open Gundam fan, making this casting not merely a publicity stunt but a choice grounded in genuine understanding of the work.

Score — Shiro Sagisu

Composer Shiro Sagisu, renowned worldwide for the Evangelion series music, handled the score. For Sieg Axis, he fused the tense, angular sound of Evangelion with the heroic orchestration of Gundam, achieving a unique soundscape where both franchises’ DNA intersects.

Episode 7, “Machu’s Rebellion,” featured a motif reminiscent of the original Gundam’s BGM, sparking excited discussions among longtime fans — “That’s the music!”

Who Should Watch GQuuuuuuX?

• Fans of the original Gundam — You will be thrilled by the barrage of homages. One “That scene!” moment after another
• Newcomers who have never seen the original — Watching the original after this series doubles the enjoyment. An ideal Gundam entry point
• Evangelion fans — Tsurumaki’s direction and Khara’s visual beauty unmistakably carry Evangelion’s DNA
• New fans who came in through The Witch from Mercury — A female protagonist, the game-like Clan Battle system, and other approachable elements

The Zeknova Incident — The Greatest Mystery Driving the Story

Before diving into the second half’s analysis, let us lay out the “Zeknova Incident” — the event at the root of the entire story.

During the final stages of the One Year War, in the midst of battle at the space fortress Solomon, the Psycommu system (a system that controls the mobile suit via the pilot’s brainwaves) aboard Char’s Red Gundam went berserk. A burst of prismatic light spread outward, causing a supernatural phenomenon that altered Solomon’s orbit. And then Char vanished alongside the light — missing in action.

This event came to be known as the “Zeknova Incident,” and Char was subsequently mythologized as a hero of Zeon. The intersecting schemes of those seeking his whereabouts and those seeking to exploit his legacy set in motion the story of Sieg Axis.

The Zeknova phenomenon is a “door” connecting the canonical world and the GQ world, and it is deeply entwined with the heart of the narrative. The mystery surrounding the true nature of this supernatural event, gradually unraveled across all 12 episodes, served as a powerful hook that kept viewers engaged until the very end.

Detailed Story Synopsis — The Full 12-Episode Narrative

Early Arc: Clan Battle Entry and the GQuuuuuuX’s Awakening (Episodes 1–4)

Episode 1: “The Red Gundam” — The story opens with a flashback to the One Year War era. The “divergence from canon” — Char Aznable capturing the Gundam and White Base, repainting them red, and deploying them on the battlefield — is depicted in vivid, striking fashion. Then comes the Zeknova Incident — a shocking scene in which Char vanishes amid prismatic light. At this point, the viewer is confronted with the reality that this is a “what if” world.

The setting shifts to Side 6, Izuma Colony, in Universal Century 0085. High school student Amate Yuzuriha lives a peaceful but vaguely “phony”-feeling everyday life. One day, she collides with Nyaan, a war refugee girl fleeing from the police, and accidentally comes into possession of an illegal MS installer device. At that moment, the cutting-edge mobile suit “GQuuuuuuX,” deployed by Zeon Colonel Challia Bull, appears. In the ensuing chaos, Amate climbs into the GQuuuuuuX’s cockpit and successfully activates its Omega Psycommu.

Episode 2: “The White Gundam” — Another mystery appears before Amate in the GQuuuuuuX. An unidentified mobile suit being pursued by both the space military and the military police — a Gundam. But this Gundam is not red — it is white. A “White Gundam” close in appearance to the canonical tri-color scheme appears as “a machine that should not exist” in this world. Its pilot is Shuji Ito, a mysterious boy. He paints “Kirakira” graffiti on the colony’s outer walls and is wanted by the military police.

Episode 3: “Machu of Clan Battle” — Amate adopts the entry name “Machu” and, guided by Nyaan, enters the illegal world of Clan Battle. Shuji enters as Machu’s “MAV (partner)” to earn money. The combination of the GQuuuuuuX and the Red Gundam, with their overwhelming performance and the duo’s perfectly synchronized teamwork, defeats opponent after opponent. Their team name: the “Pomeranians.” Their exploits, streamed online, quickly become the talk of Side 6’s youth.

Episode 4: “The Witch’s War” — A fearsome opponent blocks the Pomeranians’ winning streak. Shiiko Sugai, called “The Witch,” who shot down over 100 units during the One Year War. The brutal fight against her Gelgoog forced Machu and Shuji to confront what Clan Battle means to someone with real wartime experience. For the first time, they genuinely feel the danger to their lives.

“When I’m riding the GQuuuuuuX, it feels like the world itself is trying to respond to me”
(「ジークアクスに乗っていると、世界の方が私に応えようとしてくれる」)
— Amate Yuzuriha (Machu)

This line, spoken by Amate early in the series, encapsulates her approach to the world. Not domination — but mutual response. This attitude becomes the key to unlocking the GQuuuuuuX’s true power.

Middle Arc: Contact with Challia Bull, and the Shadow of War (Episodes 5–8)

Episode 5: “Nyaan Doesn’t Know Kirakira” — The story expands beyond Clan Battle into a larger world. The “Kirakira” that Shuji paints on the colony’s outer walls — it is not mere graffiti, but a mysterious phenomenon related to Newtype resonance. Nyaan cannot “see” Kirakira. This becomes a crucial piece of foreshadowing related to her past and identity. As Clan Battle opponents, Gaia and Ortega, iconic characters from the original Gundam, appear piloting Rick Doms. The Black Tri-Stars — who should have died in the One Year War — are alive and well in the GQ world, and they bring overwhelming combat experience to bear against Machu’s team.

Episode 6: “The Kycilia Assassination Plot” — Zeon’s internal power struggle begins to seriously intertwine with the narrative. The conflict between the Gihren Zabi faction and the Kycilia Zabi faction has been intensifying beneath the surface, and its effects ripple into Side 6. Zeon Colonel Challia Bull is officially leading the search for Char, but his true purpose is rooted in a deeper struggle. Machu and her allies are drawn into this power struggle whether they like it or not. It is mercilessly driven home that Clan Battle, their “game,” is directly connected to real warfare and politics.

Episode 7: “Machu’s Rebellion” — Machu finally steps into “real war” of her own volition. The reality beyond Clan Battle — the existence of resistance fighters opposing Zeon’s rule, and the military tension surrounding Side 6. Machu, who had been fighting as a “competitor,” is forced to fundamentally reconsider what her battles mean. A combat scene accompanied by music reminiscent of the original Gundam’s BGM struck longtime fans right in the heart.

Episode 8: “Falling to the Moon” — The story returns to the One Year War-era Beginning portion (flashback arc), depicting another side of the war from Char’s perspective. In the present timeline, a shocking development befalls Nyaan. A portrayal of Kycilia Zabi’s unexpected side — glimpses of humanity beyond mere cold ambition — showcases the GQ world’s unique character reinterpretation. The story completely leaves the Clan Battle phase behind and accelerates into “the true crisis” wrought by the remnants of the One Year War.

Final Arc: The Truth of Zeknova and the Conclusion (Episodes 9–12)

Episode 9: “Sharon’s Rose” — A concept central to the story’s core is revealed. “Sharon’s Rose” — it is a mobile armor deeply connected to the Zeknova Incident, and within it sleeps the consciousness of Lalah Sune. Lalah, who met a tragic end in the canonical timeline, exists in a different form in the GQ world, sustained by the power of Zeknova. The suggestion begins to emerge that this world itself may have been born from Lalah’s wish for “a world where Char does not die.”

Episode 10: “Yomagn’tho Lockdown” — The crisis escalates to a cosmic scale. Yomagn’tho (a critical area of space in the GQ world) is locked down, trapping Zeon forces, Federation remnants, and Machu’s civilian group alike. Challia Bull’s true intentions are finally revealed — the real reason for his obsession with finding Char was that, as a Newtype, he could sense “the distortion of this world.”

Episode 11: “The Alpha Killers” — A shocking truth about Shuji’s identity is revealed. Shuji is an entity who came from another world (one close to the canonical timeline) through Zeknova, and he has come to “end” the GQ world. His purpose is to liberate the consciousness of Lalah, sleeping within Sharon’s Rose — in other words, to sever the “distorted root” of this world. Machu’s GQuuuuuuX and Nyaan’s GFreD clash, both girls forced to fight while harboring feelings for Shuji. A new transformation — a black sphere form — appears, linked to the concept of “Alpha Killing.”

“Fight, the Gundam is telling me”
(「戦え、とガンダムが言っている」)
— Shuji Ito

This line, defining Shuji, is the mirror image of Amuro’s awakening through battle in the original Gundam. But in Shuji’s case, the ambiguity of whether he is being “ridden” by the Gundam or riding it of his own will creates an unsettling tension unique to this story.

Episode 12: “That’s Why I…” — The finale. Shuji boards the Gundam (the white RX-78-2) and attempts to “kill” Sharon’s Rose — Lalah — to end the GQ world. Meanwhile, Char strikes down Kycilia and settles his score with Challia.

And Machu makes her choice. She rejects Shuji’s decision to “end this world” and stands against him with the GQuuuuuuX’s true power. The GQuuuuuuX generates a massive beam axe and severs the head of the white giant Gundam that appeared from the other world. The awakened Lalah triggers a Zeknova event, causing Yomagn’tho — the “door” between worlds — to vanish.

What saved everyone in the final battle was Machu’s pure emotion: “I love this world.” Not logic, but emotion. Not reason, but feeling. This redefined the original Gundam’s message — “Newtypes are not tools for killing” — in a 2025 form.

In the final scene, the GQuuuuuuX departs as an autonomous unit into the silver beyond. Machu returns to Earth and looks up at the sky. Countless GQ particles flow across it like a river of light. Machu, Nyaan, Char, Challia Bull — the survivors each begin walking their own path.

“I have a place to go home to. Nothing could make me happier!”
(「帰れる所があるんだ。こんな嬉しいことはない！」)
— Amate Yuzuriha (Machu), final episode

An homage to the scene in the original Gundam’s finale where Amuro returns to his comrades. Just as Amuro in the canonical timeline said, “I still have a place to go home to” (「僕にはまだ帰れる所があるんだ」), Machu too — having survived the end of the world — found her place to return to.

Some may find this ending “too happy.” For those expecting a bittersweet conclusion in the vein of the original Gundam or Zeta Gundam, the finale’s brightness may feel insufficient. But as director Tsurumaki said, “I prioritized emotion over logic” — Sieg Axis is a work that unashamedly, wholeheartedly depicts the message that “emotion can change the world.”

Perhaps that was the message needed in 2025. In an era without clear answers, the beauty of choosing through emotion rather than logic. Sieg Axis spent 12 episodes proving that “beauty.”

In-Depth Character Analysis (Spoilers)

From this point onward, we examine each character through the lens of the story’s conclusion.

Amate Yuzuriha (Machu) — The Girl Who Saved the World by “Responding”

As the story progresses, Amate grows from a mere Clan Battle participant into someone who holds the fate of the world in her hands. But what drives her is not a heroic sense of duty — it is simple emotions: “I want to see Shuji,” “I want to save Nyaan,” “I love this world.” Her “strength” lies not in combat ability, but in the purity of her emotions.

Where Amuro in the original Gundam was “thrown into a situation where he had no choice but to fight” and awakened through that process, Amate chooses to “respond” to the world of her own free will. The GQuuuuuuX’s Omega Psycommu is a device that allows the pilot to resonate with the world, and it perfectly aligned with Amate’s fundamental desire to “connect with others.”

When Machu rejected Shuji’s choice to “end this world” in the finale, it was not simply a “righteous decision.” It was a declaration of emotion — that she loves this world, even if it is a distorted parallel world. That decision unlocked the GQuuuuuuX’s true power and led to the awakening of the Endymion Unit.

Shuji Ito — The Shadow of “Amuro” Who Crossed Between Worlds

The revelation of Shuji’s true identity in the final arc — a visitor from another world — was the series’ greatest shock. He is an entity who came to correct the “distortion” of the GQ world, with a mission to liberate Lalah’s consciousness sleeping within Sharon’s Rose.

But in the finale, touched by Machu’s emotions, Shuji chose not to destroy the GQ world but to accept Machu’s love and return to his own world. Whether he is “Amuro himself” or “a substitute for Amuro” remains a point of ongoing debate, which the creators have deliberately left ambiguous. The voice of Amuro (Toru Furuya) heard from the Endymion Unit during the final battle deepened this mystery further.

Nyaan — The “Kirakira” That War Stole

Nyaan’s essence is distilled in the fact that she “cannot see Kirakira.” The Kirakira that Shuji paints — the prismatic light born from Newtype resonance — Nyaan alone cannot see it. It symbolizes what war took from her, and represents the pain of losing the ability to “connect” with others.

From the mid-series onward, Nyaan pilots the GFreD and wages her own fight. While Amate connects with the world through “responding,” Nyaan confronts the world through “dominating.” This contrast creates a poignant rift between the two girls. But in the end, Nyaan too finds a place to return to, alongside Machu.

Challia Bull — The Man Who Sensed “the World’s Distortion” as a Newtype

Challia’s true intentions are revealed in Episode 10. As a Newtype, he could sense the “distortion” of this world, and he was the person closest to the truth of the Zeknova Incident. It was Challia’s decision to “deploy” the GQuuuuuuX to Machu, and it can be interpreted that he intentionally entrusted the fate of this world to the younger generation.

Char Aznable — The Return of the Vanished Hero

In the GQ world, Char is depicted as a mythologized hero. After vanishing in the Zeknova Incident, he returns in the story’s final arc, strikes down Kycilia, and significantly drives the plot forward. The coexistence of the new-generation Char voiced by Yuuki Shin and the voice of Shuichi Ikeda (the original Char) heard in the finale symbolized the inheritance of a character across 45 years.

In the canonical timeline, Char was “a man of revenge” — harboring hatred for the Zabi family, scheming behind his mask. But the GQ world’s Char is “a figure elevated to heroic status” regardless of his own will, mythologized against his wishes. This portrayal of Char as an “unwilling hero” was a fresh reinterpretation for fans of the original Gundam.

Annqi — A Woman on the “Winner’s Side” of Zeon Who Questions the System

Despite being Zeon-born, Annqi’s critical stance toward Zeon’s ruling system symbolizes the social structure of the GQ world — “even within victorious Zeon, there is discontent.” Even after the story shifts into its wartime phase, Annqi’s pragmatic judgment and connections save Machu and the others multiple times.

Mariya Ise’s performance exquisitely balanced the dry pragmatism of a money-savvy businesswoman with deep affection for her comrades. Annqi’s expression as she watched the Pomeranians’ battles on her monitor was an emotional touchstone for viewers in every episode.

The Endymion Unit Awakening — The GQuuuuuuX’s True Form

In the final battle, when Amate’s emotions reach their peak, the GQuuuuuuX transforms into the Endymion Unit Awakened form. This radiant form, distinct from its normal appearance, is the result of the Omega Psycommu fully synchronizing with Machu’s emotions.

The massive beam axe generated during awakening operates on an entirely different level from standard armaments. It is less a “weapon” than a materialization of Machu’s will to “protect this world.” The scene in the finale where this axe severs the head of the Gundam from the other world was both visually and narratively worthy of serving as the climax.

Original Gundam Reference Table — Twice the Fun When You Know the Source

GQuuuuuuX is a grand remix of the original Mobile Suit Gundam. Characters, mobile suits, dialogue — references to the “source material” are scattered everywhere. Those who know the original will be thrilled by the “That scene!” moments, and those who do not will look at this table and feel the urge to watch the original too.

Director Tsurumaki has repeatedly stated, “I want to convey the appeal of the original Gundam to younger generations who don’t know it.” Sieg Axis magnificently fulfilled that role as a bridge between generations. Below is a list of the key correspondences.

Element	Original Gundam (Canon)	GQuuuuuuX (IF World)
Gundam’s Color	White (Federation MS)	Red (Stolen by Char and repainted red)
Gundam’s Pilot	Amuro Ray (Federation)	Char Aznable → Shuji
One Year War Outcome	Federation victory	Zeon victory (Federation in complete retreat)
Char’s Position	Rival (enemy)	Vanished hero (mythologized figure)
Challia Bull	A Newtype who briefly appeared in the TV series (quickly killed off)	A major character with a pivotal role. “The Man Who Returned from Jupiter”
Dr. Flanagan	An almost name-only existence	Actively involved in the story
Sayla Mass	White Base communications officer → pilot	Federation MS pilot, piloting a Guncannon
Ramba Ral	A great Zeon commander. Killed mid-series	Survived. Promoted to Lieutenant
Gaia & Ortega	Black Tri-Stars (Dom pilots)	Return in Rick Doms (GQ)
Kirakira	The psychedelic resonance scenes between Amuro and Lalah	Expanded into a recurring motif throughout the story as a prismatic space
“Hello, are you in a hurry?” (「こんにちわ お急ぎですか」)	The spy Miharu’s contact code	A passphrase used by Nyaan
Last Shooting	The iconic scene from the original finale	Recreated with the roles reversed
“I have a place to go home to” (「帰れる所がある」)	Amuro’s monologue in the finale	Machu’s monologue in the finale
“Now let me see…” (「見せてもらおうか」)	Char’s (Shuichi Ikeda) iconic line	Spoken anew by the new Char (Yuuki Shin)

Director Tsurumaki has repeatedly stated his desire to “convey the appeal of the original Gundam to younger generations who don’t know it.” Indeed, a phenomenon emerged where young viewers who watched Sieg Axis began watching the original Gundam — leading some to call it “a bridge between the Reiwa and Showa generations.”

Iconic Lines & Scenes

Sieg Axis contains both homages to the original Gundam and its own unforgettable moments. Here are the most memorable.

“Fight, the Gundam is telling me”
(「戦え、とガンダムが言っている」)
— Shuji Ito

The line that defines Shuji. The unsettling notion that the Gundam itself possesses a “will” shines light on the original Gundam’s theme of “Newtype-MS resonance” from an entirely different angle. The series’ most iconic quote — it was even put on t-shirts.

“You’d better run… the Gundam is telling me”
(「逃げた方がいい…とガンダムが言っている」)
— Shuji Ito

A variation of “Fight.” The fact that what “the Gundam says” changes depending on the situation suggests that Shuji perceives the world through the Gundam’s “voice.”

“When I’m riding the GQuuuuuuX, it feels like the world itself is trying to respond to me”
(「ジークアクスに乗っていると、世界の方が私に応えようとしてくれる」)
— Amate Yuzuriha (Machu)

A single line that perfectly captures the relationship between Amate and the GQuuuuuuX. Not “domination” but “resonance.” This attitude unlocked the GQuuuuuuX’s true power and led to victory in the final battle.

“Now then, let me see what this mobile suit can do”
(「では見せてもらおうか。このモビルスーツの性能とやらを」)
— Char Aznable (Yuuki Shin)

The iconic line originally spoken by Char (Shuichi Ikeda) in the original Gundam, reprised by the GQ world’s new Char (Yuuki Shin). Delivered with restraint, it gave new resonance to a 45-year-old line.

“I have a place to go home to. Nothing could make me happier!”
(「帰れる所があるんだ。こんな嬉しいことはない！」)
— Amate Yuzuriha (Machu), final episode

An homage to Amuro’s line from the original Gundam’s finale: “I still have a place to go home to” (「僕にはまだ帰れる所があるんだ」). The final scene, where Machu — having protected the GQ world — finds her place to return to, was a moment that moved even fans of the original to tears.

Iconic Scenes

The Recreation and Reversal of the Last Shooting — The “Last Shooting,” in which the Gundam fires its final shot in the original Gundam’s finale, is the franchise’s single most iconic image. Sieg Axis recreated this composition while reversing the roles. The canonical Gundam and the GQ world’s Gundam facing off — a meta “battle between worldviews” — left a powerful impression despite sparking fierce debate among fans.

The Legendary Voice Actors’ Appearance in the Finale — The finale featured Shuichi Ikeda (the original Char), Toru Furuya (Amuro), and Keiko Han (Lalah). The “voices” of characters from 45 years ago echoing through a 2025 story created an emotion that transcended generations. The moment Toru Furuya’s voice was heard from the Endymion Unit was received as a message: “Newtypes transcend time and worlds.”

Analysis — The Mysteries of the GQ World and the Possibility of Season 2

The Truth Behind Zeknova — Why Was the GQ World Created?

The most hotly debated question throughout the story is: “Why does the GQ world exist?” Episode 9 suggests the possibility that Lalah’s consciousness, sleeping within Sharon’s Rose, wished for “a world where Char does not die” — and that wish gave birth to the GQ world.

In the canonical timeline, Lalah perishes amid the battle between Amuro and Char. To escape that pain — or to protect Char — Lalah’s Newtype abilities triggered the Zeknova event and caused history to diverge. If this interpretation is correct, then the entire GQ world is a massive “what if” born from “Lalah’s wish.”

Examining the “Shuji = Amuro” Theory

Whether Shuji is “Amuro himself” or “a substitute for Amuro” is a question the creators have deliberately avoided answering directly. However, several pieces of evidence exist.

Evidence supporting the Amuro theory:
– The voice of Toru Furuya (Amuro’s voice actor) was heard from the Endymion Unit
– He piloted the White Gundam (the canonical tri-color version)
– Shuji’s stated origin as being “from a world close to the canonical timeline”

Evidence supporting the “different person” theory:
– Shuji has his own distinct name — “Shuji Ito”
– His personality and behavior patterns differ significantly from Amuro’s
– He is voiced by a different actor (Shuji = Shimba Tsuchiya; Amuro = Toru Furuya)

The most widely accepted interpretation is that Shuji is “an entity who inherited Amuro’s soul” or “a different body born from Newtype consciousness” — neither completely the same person nor completely separate.

The True Nature of the Endymion Unit

The GQuuuuuuX’s final awakened form, the “Endymion Unit,” harbors even deeper mysteries. The fact that Toru Furuya’s voice was heard from this device has fueled a persistent theory that “the Endymion Unit = the soul of the Psycoframe from the Nu Gundam that vanished alongside Axis in Char’s Counterattack.”

If this theory is correct, then the Endymion Unit is a crystallization of Amuro’s will that transcended time and worlds, and the GQuuuuuuX itself is “a vessel housing Amuro’s soul.”

What Was “Kirakira”?

The “Kirakira” that Shuji paints on the colony’s outer walls is a motif that runs through the entire work. In the original Gundam, prismatic light appeared when Amuro and Lalah resonated as Newtypes. In Sieg Axis, this “light of resonance” is called “Kirakira” and expanded into a theme for the entire story.

Being able to “see” Kirakira indicates Newtype potential, and Amate possesses this ability. Nyaan, on the other hand, cannot see Kirakira. This difference symbolizes the two girls’ fundamentally different ways of engaging with the world.

Amate discovers Kirakira through “responding,” while Nyaan loses sight of it through “dominating” — this structure is a variation on the original Gundam’s message: “Newtypes are not tools for killing.” The assertion that connecting with others requires not domination but resonance is conveyed through the beautiful visual of Kirakira.

The Possibility of Season 2

In the finale, Yomagn’tho vanished, closing the point of contact between the GQ world and “the other side.” However, the final scene — the GQuuuuuuX departing into the silver beyond as an autonomous unit — hints at a possible continuation.

Director Tsurumaki has avoided explicitly addressing a sequel, but in an interview with Diamond Online, he made a nuanced comment suggesting “there are still things I want to tell.” Given the commercial success of the theatrical film Beginning and the buzz generated by the TV series, it would not be surprising if a sequel were already in development.

Frequently Asked Questions (FAQ)

Q. Can I enjoy Sieg Axis without knowing the original Gundam?
A. Yes. The story is designed to be understandable without knowledge of the original Gundam. However, if you do know it, you will discover far more “that’s an homage to that scene!” moments, doubling your enjoyment. Watching the original after Sieg Axis is also a great approach.

Q. Should I watch both the TV series and the theatrical film Beginning?
A. Watching both is ideal, but if you are short on time, the 12-episode TV series alone tells the complete story. The theatrical film Beginning lets you watch the One Year War portion (flashback arc) in one sitting, which deepens your understanding of the world.

Q. How many episodes are there?
A. The TV series is complete at 12 episodes. Each episode is approximately 24 minutes, for a total of about 5 hours. The theatrical premiere Beginning is approximately 2 hours.

Q. Is it appropriate for children?
A. There are battle scenes, but overly graphic depictions are minimal. The story content is enjoyable for children in upper elementary school and above. However, some themes (parallel worlds, the meaning of existence, etc.) have elements aimed at adult viewers.

Q. Is there a Season 2 (sequel)?
A. As of March 2026, there has been no official announcement. The final scene of the last episode leaves room for a sequel, but no production has been confirmed. Please check the official website for the latest information.

Q. What should a Gunpla beginner buy first?
A. Start with the “HG 1/144 GQuuuuuuX” (2,200 yen). No glue is required, and it can be assembled without tools. If you buy the “HG Red Gundam” next, you will have the two mobile suits that symbolize the story.

Q. How do you pronounce “Sieg Axis” and “GQuuuuuuX”?
A. Both are pronounced “Jeek-ax” (Japanese: ジークアクス / Jīkuakusu). The official spelling is “GQuuuuuuX” — “Q” followed by six “u”s, ending with “X.” It is difficult to remember, but searching for “Sieg Axis” or “GQuuuuuuX” will both work.

Q. Where can I stream it?
A. Internationally, Amazon Prime Video is the exclusive platform (240+ countries, Japanese audio with English subtitles + English dub). In Japan, it is available on Amazon Prime Video, d Anime Store, U-NEXT, Netflix, Disney+, Hulu, ABEMA, DMM TV, and more. The series is complete, so you can binge-watch anytime.

Conclusion

Mobile Suit Gundam GQuuuuuuX (Sieg Axis) stands as one of the boldest experiments in 45 years of Gundam history. The chemistry between two legendary studios — Sunrise and Studio Khara — produced an experience unprecedented in both visuals and narrative.

A story born from a single question — “What if Char had stolen the Gundam?” — journeyed through a parallel world to arrive at a universal theme: “What does it mean to love the world?” Machu’s approach of “responding” carries a message that resonates for all of us in 2025.

Those who know the original Gundam will be moved by the coexistence of nostalgia and novelty. Those who do not will be inspired by Sieg Axis to embark on a journey through 45 years of history. This show magnificently served its role as “a bridge connecting generations.”
