Gyan — Complete Guide Across All Gundam Series

The Most Beautiful Loser in the Universal Century

There is a mobile suit that lost the competition to become Zeon’s next mass-production unit — and was forgotten by history. Or rather, it should have been.

The winner, the Gelgoog, went on to be piloted by aces, manufactured by the hundreds, and deployed across every major battlefield of the One Year War. The loser was given to a single pilot — a colonel who loved antique vases more than military protocol — and sent into combat exactly once. It was destroyed alongside its pilot in the ruins of Texas Colony, and that should have been the end of its story.

Instead, it became one of the most beloved mobile suits in all of Gundam.

The Gyan. A knight in an age of gunners. A swordsman in a war of beam rifles.

For over 45 years, fans have asked the same question: “What if the Gyan had won?” What if Zeon’s next main mobile suit had been a fencing champion instead of an all-rounder? What if the knight had defeated the samurai?

And then, in 2025, Mobile Suit Gundam GQuuuuuuX answered that question. The Gyan returned as the Gyan Hakuji-Packs (MS-15/H) — a white-and-gold knight wielding a 27.3-meter lance called the “Hakuji,” piloted by a Newtype prodigy named Xavier Olivette.

This is the story of how a loser outlasted every winner.

Specifications — The Original Gyan (YMS-15)

Field	Detail
Model Number	YMS-15
Head Height	19.9m
Empty Weight	52.7t
Loaded Weight	68.6t
Generator Output	1,360kW
Total Thruster Thrust	56,200kg
Armor Material	Super-Hard Steel Alloy
Developer	Zimmad Company
Affiliation	Principality of Zeon
Pilot	Colonel M’Quve
First Appearance	Mobile Suit Gundam Episode 37 “The Battle of Texas” (1980)

The Gyan’s generator output of 1,360kW nearly matches the RX-78 Gundam’s 1,380kW — remarkable for a machine designed to pour all that energy into close-combat performance rather than ranged weapons. Its thruster output of 56,200kg was standard for Zeon suits of the era, but adequate for the burst acceleration needed in melee engagements. The critical absence was ranged weaponry — the very thing that sealed the Gyan’s fate in the adoption competition.

Development — The Zimmad vs Zeonic Rivalry

To understand the Gyan, you need to understand the corporate war behind it.

Zeonic Company — The Kings of Zaku

Zeonic developed the MS-05 Zaku I and MS-06 Zaku II — the mobile suits that conquered the Earth Sphere and gave Zeon its early-war dominance. They essentially invented the mobile suit as a weapon of war. Their influence within the Zeon military was immense, and any competitor faced an uphill battle against their entrenched position.

Zimmad Company — The Rebel Challenger

Zimmad’s design philosophy stood in sharp contrast to Zeonic’s balanced approach. Where Zeonic built versatile machines that any pilot could use, Zimmad favored high-output propulsion technology with emphasis on firepower and armor — specialist machines for specialist pilots.

Zimmad’s first bid for a main production contract was the EMS-04 Zudah, powered by the ferocious “Saturn Engine.” The engine delivered extraordinary output, but its control problems caused catastrophic accidents. The Zeon military chose Zeonic’s safer, more mass-producible Zaku I. Zimmad was a loser from the very beginning.

But they didn’t give up. They found their niche with the MS-09 Dom, whose hover propulsion system gave ground forces tactical mobility that no Zaku could match. The Dom proved that Zimmad’s engineering brilliance could translate into battlefield success — if given the right application.

The Second-Period MS Development Program — The Final Contest

Late in the One Year War, the Federation’s deployment of the RX-78 Gundam exposed the obsolescence of Zeon’s MS technology. A next-generation mass-production mobile suit with standard beam weaponry became urgent. Two companies answered the call:

• Zeonic proposed the MS-14 Gelgoog: beam rifle + beam naginata. A generalist.
• Zimmad proposed the YMS-15 Gyan: beam saber + missile shield. A specialist.

The Gelgoog won. Its ability to handle both ranged and close combat was deemed more valuable than the Gyan’s close-quarters brilliance.

From a military standpoint, it was the right call. Wars are won by armies, not duellists. Not every pilot has M’Quve’s swordsmanship. A machine that delivers consistent results regardless of who’s in the cockpit will always beat a machine that demands an artist.

But that’s precisely what makes the Gyan special. It exists outside the logic of military procurement — in the realm of “what if.” What if every pilot were an artist? What if war were a duel? The Gyan embodies a beautiful impossibility, and that impossibility has captivated fans for over four decades.

Weapons — The Knight’s Arsenal

Weapon	Type	Detail
Beam Saber	Melee	High-output prototype. The first standard beam saber on a Zeon MS
Shield-Mounted Hide Bombs	Deployable	25 space mines concealed within the shield
Shield-Mounted Needle Missiles	Ranged	60 micro-missiles launched from the shield surface

The Beam Saber — Zeon’s First

The Gyan carries the first beam saber ever equipped as standard armament on a Zeon mobile suit. While previous Zeon machines relied on heat hawks and heat sabers for melee combat, the Gyan brought a true beam blade to the battlefield — the same type of weapon that gave the Gundam its close-combat edge.

Its prototype-grade output allowed it to trade blows evenly with the Gundam’s own saber. M’Quve’s fencing-style thrusts at Texas Colony proved just how lethal this weapon could be — even Char expressed surprise at M’Quve’s combat performance, noting it exceeded his expectations.

The Shield — Defense and Deception in One

The Gyan’s large circular shield is far more than a defensive tool. It conceals 60 needle missiles on its surface and 25 hide bombs (space mines) on its reverse — transforming a seemingly passive piece of equipment into an active tactical weapon.

M’Quve’s use of this shield at Texas Colony was masterful. He deployed the hide bombs throughout the colony interior, creating a minefield that restricted the Gundam’s freedom of movement. With Amuro boxed in, M’Quve pressed the attack with his beam saber — turning the Gyan’s lack of ranged weapons from a weakness into a strategic choice. The shield allowed M’Quve to control the battlefield itself, compensating for the Gyan’s singular focus on melee combat.

This design philosophy suggests that the Gyan was never meant to be a “defective machine without a rifle.” It was designed for a different kind of war — one fought with cunning and steel.

Pilot: Colonel M’Quve — The Aesthete Who Went to War

Field	Detail
Name	M’Quve
Rank	Colonel (TV) / Lieutenant General (THE ORIGIN)
Affiliation	Zeon Assault Mobile Corps, under Kycilia Zabi
Position	Commander, Odessa Mining Base
Voice Actor	Kaneto Shiozawa (TV) / Takumi Yamazaki (THE ORIGIN)
Age	25 (official setting)

The Two Faces of M’Quve

M’Quve is one of the most paradoxical characters in the Gundam franchise — a man who is simultaneously a cold strategist and a passionate aesthete.

The Strategist. As commander of the Odessa mining operation, M’Quve ensured a steady flow of mineral resources to the Zeon homeland — a logistical achievement that arguably sustained the entire war effort. His own words made this clear:

“This battle is not the end of the war. Think about the quantity of mineral resources we’ve shipped back… Zeon can fight for another ten years.”

This wasn’t empty boasting. M’Quve understood something that frontline warriors like Dozle Zabi did not: wars are won by supply lines, not heroics. He was a strategist who thought in decades, not battles.

The Aesthete. In his occupied territories, M’Quve devoted himself to collecting antiques — particularly white porcelain vases believed to date from China’s Northern Song dynasty. Episode 16 shows him flicking a vase with his finger to enjoy its resonance, a gesture of genuine cultural appreciation in the middle of a war zone. His love of beauty wasn’t an affectation — it was fundamental to who he was.

The Unexpected Humanity. Often dismissed as a conniving schemer, M’Quve showed surprising moments of conscience. When ordered to detonate the Odessa base, he hesitated — “There are still soldiers inside.” He also took action to rescue troops who had escaped from Solomon. The picture of M’Quve is more complex than his reputation suggests.

Absolute Loyalty to Kycilia

M’Quve’s devotion to Kycilia Zabi went beyond military duty. His willingness to do anything for “Lady Kycilia” resembles the loyalty of a medieval knight to his liege — which makes his piloting of the knight-themed Gyan poetically perfect. No other pilot in the Universal Century was more suited to this machine.

Key Quotes

“This battle is not the end of the war. Think about the quantity of mineral resources we’ve shipped back… Zeon can fight for another ten years.”
— During the Odessa retreat

“We must defeat the Gundam — we can’t let Char get ahead of us!”
— Before sortieing in the Gyan

“Oh… Uragan, please deliver that vase to Lady Kycilia… It is… a good one.”
— His final words at Texas Colony

That last line is one of the most famous dying words in all of anime. In his final moment, M’Quve thought not of victory or defeat, not of the war or his career — but of a single vase and the person he wanted to receive it. The futility of war and the persistence of human connection, compressed into a single sentence.

The Duel at Texas Colony — Episode 37 “The Battle of Texas”

Why M’Quve Fought

After his defeat at Odessa, M’Quve returned to space seeking redemption. When he spotted White Base in the Side 5 sector ahead of the battle for Solomon, he made the fateful decision to sortie personally in the Gyan.

He didn’t have to. He could have directed subordinates, set traps from a command post, applied the strategic thinking that had made him successful at Odessa. Instead, he chose single combat. Whether this was warrior’s pride, a desire to prove himself before Kycilia, or the reckless impulse of a man with nothing left to lose — it was the most human decision M’Quve ever made.

The Battle

M’Quve’s tactics were characteristically cunning.

Phase One: The Lure. He drew the Gundam into the abandoned Texas Colony, where the enclosed space negated the Gundam’s advantage in ranged combat and favored the Gyan’s melee specialization.

Phase Two: The Minefield. He deployed hide bombs throughout the colony interior, creating a floating maze of mines that restricted the Gundam’s movement. One wrong move would trigger an explosion — Amuro had to navigate the minefield while simultaneously fencing with the Gyan.

Phase Three: The Duel. With the Gundam’s mobility limited, M’Quve attacked with his beam saber. His fencing-style thrusts were so precise that even Char, observing from afar, admitted M’Quve was fighting beyond expectations. The Gyan’s saber clashed against the Gundam’s in a display of swordsmanship rarely seen in the series.

Phase Four: The Barrage. M’Quve unleashed the shield’s needle missiles, mixing ranged harassment with close-quarters pressure to keep Amuro off-balance.

M’Quve’s End

But Amuro’s awakening Newtype abilities outpaced every stratagem. He navigated the minefield on instinct, read the Gyan’s blade patterns, and ultimately sliced the Gyan apart with a dual beam saber strike from both sides.

In the exploding cockpit, M’Quve spoke his final words:

“Oh… Uragan, please deliver that vase to Lady Kycilia… It is… a good one.”

Not a curse, not a battle cry — a request about a vase. In that moment, Mobile Suit Gundam proved it was never about the machines. It was always about the people inside them.

The GQuuuuuuX Gyan Hakuji-Packs (MS-15/H) — The White Knight Returns

Specifications

Field	Detail
Model Number	MS-15/H
Unit Name	Xavier’s Gyan (Hakuji Equipment)
Affiliation	Principality of Zeon — Kycilia’s Assault Mobile Corps
Pilot	Ensign Xavier Olivette
Colors	White with gold accents (standard units: dark navy blue)
First Appearance	GQuuuuuuX Episode 7 “Machu’s Rebellion” (2025)

In 2025, Mobile Suit Gundam GQuuuuuuX brought the Gyan back from the dead — and this time, it got to win.

Redesigned by Ikuto Yamashita (of Evangelion fame) and deployed as Kycilia’s elite guard unit, the GQuuuuuuX Gyan fulfills the dream that the original never could: mass production, battlefield deployment, and a pilot worthy of its knightly heritage.

The critical difference from the original timeline? In GQuuuuuuX’s version of the One Year War, the Gyan was formally adopted as a production mobile suit. The loser of the Zeonic-Zimmad competition became the sword arm of Kycilia’s faction — a 45-year-old “what if” made canon.

The Hakuji Lance — 27.3 Meters of Compound Armament

The Hakuji is a weapon that exceeds its wielder. At 27.3 meters, it is longer than the Gyan itself (19.9m) — a lance that dwarfs its knight.

Function	Detail
Melee Attack	Piercing tip effective against electromagnetic shields
Ranged Attack	3 railguns mounted at the tip
Propulsion Assist	Built-in thrusters and propellant tanks serve as an external booster
Grip Design	Jamadhar (Indian punch-dagger) style

The Hakuji’s design philosophy is seamless transition from charge to strike. The booster accelerates the Gyan into a lance charge, the piercing tip penetrates electromagnetic shields, and the railguns deliver follow-up fire — all in one fluid motion. It is the concept of a knight’s lance charge translated into mobile suit engineering.

In Episode 10, nine mass-production Gyans wielding Hakuji lances executed a coordinated assault against the Big Zam. The lances’ thrust carried them through explosions while their railguns suppressed the target’s visibility — demonstrating the Hakuji’s terrifying effectiveness as a formation weapon.

Additional Weapons

Weapon	Detail
Beam Sabers x2	Carrying forward the original Gyan’s melee heritage
Gyan Shield CE-1	Large circular shield with 6 missile tubes

The reduction from the original’s 60 needle missiles to 6 missile tubes reflects the Hakuji’s introduction as the primary weapon — the shield’s role shifted from “trick weapon” to “pure defense with auxiliary firepower.”

Pilot: Xavier Olivette — The Elite Who Lives a Contradiction

Field	Detail
Name	Xavier Olivette
Rank	Ensign
Background	Side 5 refugee, displaced by the Battle of Loum
Education	Flanagan School, graduated top of class
Affiliation	Kycilia’s forces, Assault Mobile Corps
Voice Actor	Seiichiro Yamashita

Fighting for the Army That Destroyed His Home

Xavier Olivette’s entire existence is built on contradiction.

A war refugee from Side 5, orphaned by the Battle of Loum, he joined the very military that destroyed his homeland. He graduated top of his class from the Flanagan School — Zeon’s premier Newtype research institution — only to fail at activating the GQuuuuuuX’s Omega Psycommu system, watching helplessly as the machine was taken from him by Machu.

He is handsome, composed, and intellectual — yet carries an unmistakable shadow. A model soldier who responds to death with unsettling detachment. A Kycilia loyalist who was secretly assigned to monitor Challia Bull for signs of being a Gihren spy. These layers of contradiction make Xavier one of GQuuuuuuX’s most compelling characters.

The Complex Bond with Challia Bull

Xavier was planted in Challia’s unit as a surveillance operative, tasked with reporting Challia’s activities back to Kycilia. But proximity bred genuine respect. Xavier came to sincerely admire Challia, and Challia recognized Xavier’s talent, saving him from danger multiple times.

The tragedy of their relationship lies in its trajectory: from watcher and watched, to mutual respect, to inevitable opposition. Their final confrontation carries the weight of every moment they shared.

Newtype Awakening

Xavier was recognized as a Newtype upon graduating from the Flanagan School. But the GQuuuuuuX’s Omega Psycommu refused to respond to him — its “lock” forced him into manual control. It was later revealed that this lock was actually a limiter device — his abilities weren’t lacking; they were being suppressed by the system itself.

The awakening came in Episode 11, “The Alpha Killers.” Challia Bull’s Kikeroga launched an all-range attack — countless bits converging from every direction. And Xavier dodged every single one.

“Don’t give me that! You said you’d create a world where Newtypes can live as Newtypes!”

With those words, Xavier achieved full Newtype awakening — proving that the Flanagan School’s top graduate had been held back not by lack of talent, but by the machines meant to measure it. Considering that the original Gyan’s pilot was defeated by a Newtype, a Newtype-awakened Gyan pilot feels like 45 years of cosmic justice.

Key Quotes

“This thing… it’s the real Gundam!”
— First encounter with the Red Gundam

“Does the Commander still think he’s fighting a war?”
— On Challia’s covert operations

“Don’t give me that! You said you’d create a world where Newtypes can live as Newtypes!”
— Final episode, confronting Challia Bull

GQuuuuuuX Episode Guide — The Gyan’s Finest Hours

Episode 7: “Machu’s Rebellion” — The White Knight Arrives

The Gyan Hakuji-Packs’ combat debut. When Deux Murasame’s Psycho Gundam launches an assassination attempt on Kycilia, Xavier sorties in the white Gyan to defend his commander.

Breaking through the Psycho Gundam’s reflector armor ring, the white knight charges to Kycilia’s side — a vassal racing to save his liege. The GQuuuuuuX “thruster doctrine” design philosophy is on full display here: the Hakuji’s integrated boosters merge lance and mobile suit into a single charging weapon, delivering a spectacle of speed and power that immediately established the Gyan as one of GQuuuuuuX’s signature machines.

Episode 10: “The Io Magnusso Blockade” — The Gyan Earns Its Place

Nine mass-production Gyans, each armed with a Hakuji lance, take on the Big Zam — one of the most formidable mobile armors in Universal Century history.

The formation attack is breathtaking: Hakuji boosters driving the Gyans through walls of explosive fire, railgun salvos suppressing the Big Zam’s visibility, coordinated lance charges piercing its defenses. The machine that was “rejected” in the original timeline is here the backbone of Kycilia’s elite forces — a moment of vindication for every fan who ever believed the Gyan deserved better.

Episode 11: “The Alpha Killers” — Awakening

Challia Bull’s Kikeroga unleashes its all-range attack. Bits swarm from every angle, closing in on Xavier’s Gyan from all directions.

Xavier dodges them all. Every single one. In that moment of full Newtype awakening, the White Knight becomes untouchable — an echo and inversion of M’Quve’s defeat at the hands of Amuro’s emerging Newtype powers 45 years earlier. Where the original Gyan fell to a Newtype, this Gyan rises as one.

Design Secrets — Giving the Knight a Form

The Original Gyan (1979) — Tomino’s Memo and Okawara’s Hand

The Gyan’s origin traces to a rough sketch by director Yoshiyuki Tomino, annotated: “#37 defeated mobile suit ‘Hakuji’ — for M’Quve.” The machine’s original name was not Gyan, but Hakuji — a name that would wait 45 years to find its destiny.

Even at the sketch stage, the fencing/medieval knight motif was already established. The beam saber and round shield combination was a deliberate importation of European chivalry into the Universal Century.

The distinctive frog-mouth helm head design — modeled on 14th-15th century European jousting helmets — is the visual key to the Gyan’s identity. These helmets traded visibility for maximum protection during lance charges, making them perfect for a mobile suit built for frontal assault. The narrow visor slit and heavy face guard communicate “charging knight” at a glance.

Kunio Okawara cleaned up Tomino’s rough into the final design. Among Zeon’s gallery of curved, mono-eyed faces, the Gyan’s Western-armored visage stands alone — an outsider even in appearance, befitting a machine that was rejected by its own military.

The Name Swap — “Gyan” Was Meant for Another Machine

A fascinating production-era swap occurred during development:

• “Gyan” was originally the planned name for the Gelgoog
• “Hakuji” was originally the planned name for this machine

The exact reason for the swap is lost to production history, but the sharp, dramatic sound of “Gyan” arguably fits the knightly mobile suit better than the measured “Gelgoog.” And the GQuuuuuuX staff, aware of this trivia, resurrected “Hakuji” as the name of the lance weapon — the original name returning after 45 years, not as a mobile suit designation, but as a weapon befitting a knight.

GQuuuuuuX Redesign (2025) — Ikuto Yamashita’s Vision

Ikuto Yamashita — best known for designing the Evangelion units — handled the mechanical design for GQuuuuuuX. Every mobile suit in the series was filtered through his aesthetic: “What if an Eva designer drew Gundam?”

The story of how the Gyan was chosen for GQuuuuuuX is itself a kind of redemption. When discussing which MS should serve as Kycilia’s elite guard, director Kazuya Tsurumaki initially proposed the Asshimar. But Yamashita submitted his Gyan redesign, and its knightly beauty won the role — a creative “adoption competition” that mirrored and reversed the original’s rejection.

Key design choices:

• Frog-mouth helm preserved and enhanced: The original head design was carried forward with increased “armored” presence
• Increased lower-body volume: A silhouette closer to the Gyan Eos variant, creating a more imposing knightly stance
• Thruster doctrine: Additional exhaust ports throughout, reflecting GQuuuuuuX’s design-wide emphasis on visible propulsion
• White porcelain coloring: White body with gold accents — M’Quve’s beloved vase rendered as a color scheme

In an interview with Hobby Japan, Yamashita stated: “I design to tell stories beyond performance specs.” The Gyan’s redesign tells a story of a loser’s pride and a knight’s enduring beauty — things no spec sheet could ever capture.

Variants — “What If the Gyan Had Won?”

Though rejected in the original timeline, the Gyan has appeared across dozens of “what if” scenarios.

Model	Name	Series	Distinctive Feature
YMS-15E	Gyan Eos	MSV	High-Mobility Gelgoog booster retrofit for actual combat deployment
MS-15B	High Mobility Gyan	Gihren’s Greed	Beam lance armament. The “IF adoption” development path
MS-15C	Gyan Cannon	Gihren’s Greed	180mm cannons x2 + grenade launchers. The Gyan’s weakness “fixed”
MS-15Kg	Gyan Krieger	Gihren’s Greed	The ultimate Gyan-line evolution. “Ten more years” made real
MS-15K	Gyan Kai	G Generation	Axis-rebuilt redesign. The ancestor of the R-Jarja
—	Gyan Marine	MSV-R	Amphibious variant
—	Gyan (Thunderbolt)	Thunderbolt Gaiden	Elite officer-use in an alternate timeline
—	Gyancelot	Build Fighters Try	Gunpla battle custom. The knight concept made explicit
MS-15/H	Gyan Hakuji-Packs	GQuuuuuuX	Yamashita redesign. Hakuji lance equipment for a new era

The Gyan Eos represents Kycilia’s refusal to accept the competition results: two prototype Gyans were transferred to her Assault Mobile Corps and refitted with Gelgoog high-mobility backpacks through Zimmad-Zeonic collaboration. “If the military won’t adopt it, we’ll use it anyway.”

The High Mobility Gyan imagines what would have happened if the Gyan had won the adoption competition. The beam saber evolves into a beam lance — deepening the knight motif.

The Gyan Cannon is a fascinating contradiction: a close-combat specialist fitted with 180mm cannons. It fixes the Gyan’s “no ranged weapons” weakness, but in doing so, abandons the very philosophy that made the Gyan unique.

The Gyan Kai was rebuilt at Axis during the Neo Zeon era, and its design data was passed down to the R-Jarja — proof that the Gyan’s knightly DNA survived across generations.

And the Gyancelot — from Build Fighters Try — is the fan dream made plastic: a Gyan that leans into the knight aesthetic without reservation, complete with cape and lance.

Cultural Impact — “It Is a Good One” and the Legend It Created

The Gyan as “The Beauty of Defeat”

The Gundam universe is full of powerful machines, iconic machines, machines that won wars. But there is only one machine that is loved because it lost.

Rejected in the competition, destroyed in its only sortie, remembered only through its pilot’s eccentric last words — the Gyan should be a footnote. Instead, it occupies a unique cultural position as Gundam’s ultimate “what if” machine. Every alternate timeline, every game scenario, every fan discussion that begins with “what if the Gyan had been adopted instead?” is a testament to the power of beautiful failure.

The Vase Meme

“Please deliver that vase to Lady Kycilia… It is a good one.” — M’Quve’s final words have become one of the most quoted phrases in the entire Gundam franchise.

The phrase “are wa ii mono da” (it is a good one) has entered everyday Japanese fan vocabulary — used whenever someone encounters anything of quality, from a good meal to a new Gunpla kit. Friends gift each other items with the tag line “deliver this to Lady Kycilia.” The meme’s endurance is proof that M’Quve, in death, achieved an immortality that no military victory could have provided.

In 2014, Bandai collaborated with the Noritake Company (a prestigious Japanese ceramics manufacturer) to produce an actual “M’Quve’s Vase” — a real white porcelain piece. It sold out within a single day of pre-orders. A fictional vase became a real product, and that real product became an instant collector’s item. Few anime props in history have achieved that level of cultural crossover.

Build Fighters and the Gyan Renaissance

The Gyan’s cultural status was cemented by the Gundam Build Fighters franchise.

In the original series, Susumu Sazaki’s obsessive love for the Gyan spawned what fans called the “Wonderful Gyan Festival” — a wave of appreciation for this underdog machine. In Build Fighters Try, his sister Kaoruko “Gyanko” Sazaki piloted the R-Gyagya and Gyancelot, driving Gyan-type Gunpla sales to heights the original designers never imagined.

On Pixiv, fans created countless “fake box art” images splicing the Gyan’s head onto other mecha — a meme that spread across Japanese social media. In the original Gundam lore, the Gyan was sometimes mocked as “the MS that only losers pilot.” Build Fighters gave it a worthy partner at last, and the fans responded with genuine love.

GQuuuuuuX: The Vindication

And then came GQuuuuuuX — the Gyan’s greatest redemption.

In this new timeline, the Gyan wasn’t rejected. It was mass-produced as Kycilia’s elite guard unit. It received a talented Newtype pilot in Xavier Olivette and a showcase moment — the all-range attack evasion — that ranks among GQuuuuuuX’s most celebrated scenes. It was given a name that honored both its production history and its pilot’s predecessor: Hakuji.

Fan communities erupted with joy: “The Gyan finally got what it deserved.” “M’Quve is crying happy tears in heaven.” Of all the fan service in GQuuuuuuX — a series built on reimagining the One Year War — the Gyan’s rehabilitation was widely considered the most emotionally resonant.

Forty-five years of being the beautiful loser, and then, finally, a win.

The premium collector’s piece. Die-cast joints provide heft and poseability, while the metallic paint finish achieves a “white porcelain glow” that no plastic kit can replicate. The Hakuji lance stretches to approximately 230mm — an imposing display piece.

Classic Gyan Kits

Kit	Scale	Price	Why It’s Great
HGUC Gyan (REVIVE)	1/144	1,320 yen (~$9)	2016 renewal. The definitive Gyan in plastic — outstanding proportions, articulation, and color separation
MG Gyan	1/100	P-Bandai exclusive	Light-up beam saber gimmick and M’Quve pilot figure. For collectors

The HGUC Gyan REVIVE is widely regarded as one of the best value-for-money HGUC kits ever released. At 1,320 yen, it delivers double-jointed articulation (enabling the Gyan’s signature fencing thrust pose), mono-eye movement, and excellent color separation through molded plastic — no paint required for a great-looking build.

Building Tips

• Hakuji needs its stand: The lance shifts the center of gravity so far forward that freestanding display is nearly impossible. Always use the included stand.
• Gold paint markers: Even a basic metallic gold paint marker on the accent areas elevates the kit’s “white porcelain” premium feel dramatically.
• Display alongside the REVIVE: Putting M’Quve’s classic Gyan next to Xavier’s Hakuji-Packs creates a striking 45-year design evolution comparison — the same knight, two eras.
• Seam line treatment on the Hakuji: The lance halves leave a visible seam. Cementing and sanding this seam line produces a significantly cleaner finished weapon.
