Roy Mustang

Roy Mustang (ロイ・マスタング, Roi Masutangu), the Flame Alchemist, is a State Alchemist and officer in the Amestrian State Military. A hero of the Ishval Civil War and Edward Elric's superior officer, Colonel Mustang is a remarkably capable commander who plans to become the next Führer of Amestris.

Appearance
Roy Mustang is the very picture of an attractive, sophisticated man in the prime of life. With his dark, piercing eyes and clean-shaven, babyfaced visage, the infamous colonel attracts a great deal of attention from admirers. Roy's dark hair - perhaps in keeping with his persona - is worn casually unkempt, falling over his eyes; in more formal or somber situations, however, he is known to wear it neatly slicked back. A great fan of classy attire, Mustang is rarely seen out of uniform (and even while in uniform will often don other impressive accoutrements, such as a long, black overcoat and white formalwear gloves), but when dressed in civilian clothes, he appears rather partial to the three-piece suit and black tie (frequently coupled with classic scarves, polished dress shoe and the aforementioned overcoat and gloves). It may be interesting to note that Roy tends toward dark or neutral colors in his dress, such as dark blue, brown and black tempered with minimal white.

After the events of his fight with Lust in Chapter 39: Complications at Central/Episode 19: Death of the Undying (2009 series), Roy carries a faint scar on the back of his right hand in the shape of a Transmutation Circle. He also carries a large burn wound on his left side, lower back and abdomen from the same event.

Personality
On the surface, Roy seems to be a shallow and self-absorbed man, infamous among many of his colleagues and subordinates alike for the selfish and narcissistic aura he gives off. Easily as arrogant as his young protégé Edward, Colonel Mustang is wont to act in an ostentatious manner and appears to act mostly out of self-interest rather than any sort of philanthropy. He comes off to most as a sort of cocky layabout, shirking most of his duties and delegating his paperwork to subordinates while sitting idly at his desk with an amused smile on his face as he procrastinates, but quick to take action when it appears that there is glory and military notoriety to be gained. Roy is expertly manipulative and prone to think several steps ahead of those around him, giving him a remarkable talent for making subordinates act exactly as he wishes despite appearing not to have had a hand in their decisions - all traits which make the fact that he has managed to attain the lofty rank of colonel at such a young age a matter of public gossip.

Roy also has the reputation of being an incorrigible womanizer, and it's said he spends much of his time cavorting about town with various women and wooing several of the servicewomen with his abundant charm, good looks and charisma. This adds another facet to his unpopularity among the enlisted men, many of whom have had their sweethearts and crushes romanced away from them by his hand.

However, while these traits do have a place in his real personality, much of his outward persona can perhaps be considered an intentional façade perfectly designed to cause those unfamiliar with him to underestimate his remarkable intelligence and ability. Mustang is an exceptional tactician, well-versed in various strains of combat theory and particularly talented in the realms of surreptitious information-gathering, covert operations and enemy ensnarement.

At the core, he is a remarkably devoted commander whose primary focus and personal duty is to his friends and subordinates. Though he hides it well behind a veil of cynicism and self-importance, Roy Mustang is a man who cares deeply about the people who trust and support him and goes to great lengths to ensure their safety and well-being, even at the risk of his own. As a man with considerable power, Mustang considers himself a protector to those without and acts accordingly, earning the staunch loyalty of his most trusted compatriots.

Unfortunately, his self-imposed position as protector has caused him to display a penchant toward stubbornness in regards to his pride on the field and a fiery temper, both of which have been shown to cloud his judgment in certain situations.

Relationships
Riza Hawkeye - Easily the most significant of Roy's personal relationships, his connection with Lt. Hawkeye goes deeper and further back than any other. The daughter of Berthold Hawkeye, the man who taught Roy to use alchemy in his youth, Riza has known Roy throughout his entire military career and has a personal stake in how he chooses to live his life. In turn, Roy has entrusted Hawkeye with his life as his personal assistant and bodyguard and has deemed her as both his conscience and executioner by giving her the express authority to shoot him in the back should he ever step off the righteous path. Though many speculate that Roy and Riza are involved romantically (each of them has joked about the topic over the course of the series), their relationship - while not purely professional - has shown no real signs of crossing the line into the amatory as of yet. They have however shown a mutual trust and concern for each other, as well as a fear of losing one another.

Maes Hughes - A close friend from their shared days at the military academy, Maes Hughes is Roy's closest friend inside and outside of the military. Almost constantly calling Roy on the phone or dropping into his office to say hello, Maes' uplifting persona is an active deterrent to Colonel Mustang's often gloomy disposition. Maes is also the strongest secret supporter of Roy's bid for Führer, often giving him inside information from his position in the investigations office at Central Command as well as slipping him pointers on how to achieve his dream. Though Roy often receives Hughes with disdain and annoyance, when Maes is mysteriously murdered, Roy is overcome with grief and rage to the point that he becomes almost obsessed with finding his friend's killer.

Edward Elric - Officially, Mustang is Edward's superior officer, but their relationship is far from the typical professional connection. There exists between them a sort of amicable animosity, as Roy takes a great deal of personal pleasure in teasing Fullmetal and watching him squirm under his orders and, at the same time, Ed takes pleasure in getting around his orders and showing Mustang up whenever he manages to find an opportunity. Though their meetings are fraught with a great deal of apparent, mutual dislike, Flame and Fullmetal hold a great deal of respect for one another and are compatriots as well as co-conspirators in the secret battle against the Homunculi. Having originally scouted the young boy for the State Alchemist program and formed a bond with him, Roy genuinely wishes to see Edward fulfill his goal and Edward also subtly supports Mustang's secret bid to become the Führer and improve the country.

Lt. General Grumman - Roy's superior officer from his days at East Area Headquarters, General Grumman has played a sort of grandfatherly role in Roy's development as a soldier and officer. Having taught the young Flame Alchemist everything he knows about covert operations, subordinate coordination and womanizing, Grumman feels rather fondly for his protégé and is personally responsible for the young man's speedy rise through the ranks. Roy owes Grumman a great deal and trusts him enough to seek the old man's help and advice when he finds himself in a pinch.

Flame Alchemy
Even among the elite State Alchemists, Colonel Mustang is a particularly skilled alchemist adequately versed in standard physical transmutation, experimental theory and biological alchemy. However, the brilliant skill that has earned him his state license, national notoriety and the status of "hero" during the Ishval Civil War is his remarkably powerful fire-based combat style. Mustang's unique style of combat alchemy is made possible by his custom made gloves. Made of "pyrotex/ignition cloth" and embroidered with unique flame alchemy Transmutation Circles, these gloves create a spark when Roy rubs his fingers together and allow him to manipulate the concentration of oxygen in the surrounding air, raising its density to a level at which it becomes combustible and creating pathways of oxygen through which he can direct the ensuing flame birthed by the spark. The 'snap' sound is caused by the instantaneous speed at which the gases and sparks react together and pop (not his fingers actually 'snapping', to common belief.)

While Mustang's Flame Alchemy cannot be used on rainy days because the humidity makes it impossible for his gloves to produce sparks, it becomes clear that water itself does not make the Colonel entirely as "useless" as his subordinates assume. Using the transmutation circles on his gloves, Roy is able to separate oxygen atoms from the hydrogen atoms in water molecules, isolating the two combustible gases. Though this method can only be used when a large quantity of water is present in a relatively closed-off space (and not in the rain where the air is open and separating hydrogen and oxygen for the purpose of combustion would pose far too much danger to anyone in the vicinity), with an outside source of ignition such as a cigarette lighter or a match, Roy can produce extremely powerful, localized explosions.

It has also been revealed recently that Roy is able to delegate each hand to a different flame effect, possibly due to a difference in hand dexterity. The right hand appears to allow for large explosive attacks, while the left allows for smaller, but strong and very accurate pinpoint flame attacks, demonstrated when he used his left hand to evaporate the liquid in Envy's eyes causing excruciating pain, and the right to engulf Envy in a large explosion.

Flame Alchemy is the brainchild of the master alchemist Berthold Hawkeye, who had spent several years perfecting it before his death from illness in 1905. Believing it to be the greatest and most powerful form of alchemy possible, Hawkeye refused to pass on the knowledge to Roy, who was his apprentice at the time, and instead entrusted the secrets of his search for knowledge to his young daughter Riza - tattooing the perfected array onto her back as the only physical record of its existence. The full array appears to consist of a circle corralling an inverted hexagram made up of a large air triangle and a large earth triangle, both splitting into identical pairs as they intersect, with a fire triangle at the center, pointing upward toward a flame. Below the hexagram is an image of a salamander. Outside the circle is a pair of entwined basilisks and the text of the "Libera Me" responsory repeated multiple times. After Roy gains Riza's trust and takes the Flame Alchemy knowledge for himself, he modifies the symbol somewhat for his gloves (removing the text and the basilisks in favor of a simplified circle) and uses his new knowledge to burn parts of the image off of Riza's back, erasing the important aspects of it from existence.

When he is forced to perform human transmutation and see the Truth, Roy gains the ability to transmute without a circle, clapping his hands to compensate for the sigils on his gloves being shredded. While at first he is apprehensive of this mode of alchemy, he quickly realises that because of the absence of the need for transmutation circles he is no longer limited to flame-based alchemy on the battlefield, as seen when he transmutes a stone wall to protect himself and Riza from Father's attacks.

In the Book in Figure Red omake strip, Roy reveals that he sometimes uses alchemy for the purpose of scoring a date. In his "Oxygen de Gentleman Strategy", he uses his gloves to raise the oxygen density around a specific woman to the point that she becomes dizzy. He then, rushes to her side to prevent her from falling, asks her if she is all right and follows up with other sweet words and an invitation for tea.

History
Orphaned at a young age, Roy was adopted by Chris Mustang, his father's younger sister, who brought him up with the intention of making him into a fine gentleman. Presumably in his teens, young Roy discovered an affinity for alchemy and took basic instruction in the craft from master alchemist Berthold Hawkeye in the hopes of becoming a source of strength and knowledge for the people of Amestris. However, faced with the increasing frequency of border wars, Roy eventually left his teacher's charge and enrolled in the State Military Academy with the intent of becoming a State Alchemist and devoting himself to the protection of citizens caught in the crossfire of international struggles. While at the military academy, he became friends with fellow cadet Maes Hughes, with whom he often discussed his idealistic dreams for the future of the country.

In 1905, at the age of twenty, Roy returned to the decrepit Hawkeye estate hoping to both acquire the higher echelons of Master Hawkeye's unique alchemical expertise as well as persuade his revered teacher to join the State Alchemist program so as to share his brilliance with the world. Berthold, however, refused the offer and further expressed his doubts that someone so eager to become a military lapdog was worthy of attaining the pinnacle of his research. Unfortunately, Master Hawkeye died of an unknown illness in Roy's arms that very day, leaving as his dying wish that Roy inherit his secret research notes from his daughter Riza under the condition that he look after her and vow to never use the power hidden within for ill.

At Hawkeye's funeral, after Roy revealed to Riza his own dreams of strengthening the government and protecting the people with his own strength, she in turn revealed to him that her father's secret research had been encoded in a tattoo on her back. Impressed by Roy's intentions, she entrusted her back to him in the hopes that he would use its secret to create a happy future for the people. Deciphering the code, Roy mastered Hawkeye's innovative flame alchemy and went on to pass the State Alchemist certification exam, earning the symbolic moniker "Flame Alchemist" and the military officer rank of Major.

Three years later, the Ishval Civil War had reached a fevered pitch, prompting the Führer to order combat-oriented State Alchemists into front line combat as human weapons to begin a full-blown extermination campaign against the Ishvalans. The Flame Alchemist was ordered into the Daliha district where the columns of fire ignited by his flashily destructive style of combat alchemy earned him great notoriety and the nickname "The Hero of Ishval". Re-encountering Maes Hughes and Riza Hawkeye, who had enrolled into the military academy and become an infamous sniper in the civil war since he had seen her last, the three lamented the fact that their eyes of youthful idealism had been replaced with the eyes of murderers and pondered over the unknown reasoning behind the incredible military expenses being devoted to the inexplicable wholesale slaughter of the Ishvalans, who were technically fellow Amestrian citizens.

After an exorbitant death toll, Mustang himself brought an end to the struggle in Daliha, effectively bringing the civil war to a close. However, the long and bloody struggle had all but erased the idealism of his youth; after devoting himself to the military in order to support the people, he had built himself up into the "hero" of a massacre, and only managed to save the lives of a few men stationed under him with his flames. Still, the thanks of those men inspired a new dream in the Flame Alchemist's heart. Instead of becoming part of the foundation of the country in order to protect the people, he began planning to rise above people and protect those below him with his acquired power and authority. Even if all he could protect was a few people, he would make sure that those people protected those below them and so on until the entire nation ended up benefiting from his protection. It was at that point that Roy Mustang first set his sights on the position of Führer.

As Mustang prepared to move out from the battlefield, Riza - just as guilt-ridden for her deadly role in the genocide, both direct and indirect - asked Roy to burn the record of her father's research off of her back with his Flame Alchemy so as to prevent the creation of a second "Flame Alchemist".

After the war, Mustang was promoted to Lieutenant Colonel and stationed at the East Area Headquarters in East City under Lt. General Grumman. As a new commander, he scoured the new recruits for trustworthy subordinates who would fulfill his ideals of universal protection and amassed a handful of dependable underlings including Riza Hawkeye, whom he positioned as his personal aide and bodyguard, entrusting his back to her under the agreement that she would protect him from harm and shoot him from behind if his march to power caused him to stray off of the correct path and use the knowledge she had given him with ill intentions.

In the aftermath of the war, as several State Alchemists had thrown away their licenses as penance for the atrocities they had been ordered to commit, Lt. Col. Mustang was assigned to investigate and recruit possible candidates for the State Alchemist program. One such lead brought him, along with 2nd Lt. Hawkeye, to the town of Resembool in the east in pursuit of an alchemist named Edward Elric. Upon arriving in town, Mustang discovered not only that this Edward Elric was only eleven years old, but also that the boy's empty home held the horrific telltale signs of a Human Transmutation attempt. Rushing to next door neighbor's house to confront young Edward, he made yet another discovery - that the boy had miraculously survived the Rebound from a failed Human Transmutation and managed to bind the disembodied soul of his younger brother Alphonse to a suit of armor (two unheard-of alchemical feats) at the cost of his right arm and left leg. Faced with this information, Mustang offered Edward the chance to join the program under his command, mentioning that the boy might even find a way to restore his and his brother's bodies with the resources at his disposal as a State Alchemist.

One year later, after Mustang had been promoted to the rank of Colonel, Edward arrived at East Area HQ and requested that Roy escort him to Central City for his license examination. Displaying the unique ability to transmute without a circle as well as uncommon brazenness, Edward was accepted into the program, stationed under Col. Mustang's command and granted the title "Fullmetal Alchemist". In exchange for Edward's loyalty, Roy promised to keep Edward's illegal human Transmutation attempt as well as the secret of his brother's body under wraps and granted him the leeway to venture freely around the country in search of his goal.

Eastern Command
Colonel Mustang makes his first formal appearance in Chapter 4, when his office receives word that remnants of the eastern terrorist group Blue Squad has hijacked the train on which Lt. General Hakuro is traveling with his family. Before the Colonel can take action, however, the Blue Squad members are dispatched by Edward and Alphonse Elric, who had happened to be passengers on the train as well. Upon Edward's arrival in East City, Roy introduces him to state-certified bio-alchemist Shou Tucker, whom they hope can use his expertise on chimeric alchemy to give them some insight on a different means of restoring their bodies. Unfortunately, Edward discovers that Tucker's famous past success in creating a chimera capable of human speech was the result of a human experimentation in which he sacrificed the life of his "estranged" ex-wife and that his fresh triumph was willingly gained at the cost of his young daughter Nina, to whom the Elric boys had grown quite close. Roy orders that Tucker be placed under house arrest and begins proceedings for a court-martial, sending for Lt. Colonel Maes Hughes and Major Alex Louis Armstrong from Central to escort the ex-State Alchemist to his hearing; unfortunately, they arrive at the Tucker home to find that Shou, Nina and even the military policemen guarding the estate have been gruesomely murdered by a mysterious assailant. Hughes and Armstrong inform Mustang that the modus operandi of the killings matches that of a nameless serial killer they had been tracking from Central City - a scarred man who targets State Alchemists specifically and had already slain ten around the country. Though Hughes advises Roy to lay low until the killer is caught, Mustang worries for Edward's safety and orders the military police to find and escort the Fullmetal Alchemist to the safety of the command center. When reports come in that Ed and Al have engaged a mysterious scarred assailant on the main road of town, however, Roy moves with his own forces to back them up and arrives on the scene just before the Scarred Man is able to assassinate Fullmetal. With the help of Major Armstrong - who happens to be the "Strong Arm Alchemist" - the East City forces manage to prevent Edward's demise as well as ascertain a bit more about Scar before his flashy escape: namely that his strange method of execution is a brand of alchemy that stops at the deconstruction stage and, perhaps more importantly, that the man is an Ishvalan survivor of the Civil War bent on taking vengeance for his slaughtered people.

Roy vows to apprehend and execute Scar before he can do more damage, placing a gag order on the incident with Fullmetal and initiating a citywide search for the alchemist killer as Ed and Al leave town under escort to have their injuries tended to. Though Scar manages to elude capture and leave the city, Mustang receives word from Hughes that turmoil in Central City has caused the members of Central Command to seriously consider transferring Roy to the capital. Anticipating a possible invitation to Central Command, Hughes advises Roy to amass as many supporters as possible so as to ward off opposition. However, a short time later, news reaches Roy that Hughes has been murdered. He travels to Central City to attend his best friend's funeral and learn what he can about the murder, but even with the help of Major Armstrong is only able to uncover a few key facts - Hughes' death was orchestrated by one or more unknown members of a mysterious group already under investigation, the reason for his death had to do with an unspecified plot he had uncovered which threatened the military government and someone in Central Command had placed a gag order on all other information. After being informed officially that his transfer to Central City is indeed imminent, Roy vows to get to the bottom of the mystery and avenge Maes Hughes in one fell swoop.

When Roy's transfer orders officially arrive in Chapter 25, he bids farewell to Lt. General Grumman and, in addition to receiving Grumman's chess set, requests another parting gift in the form of five subordinates to be transferred with him - Lt. Riza Hawkeye, 2nd Lt. Jean Havoc, 2nd Lt. Heymans Breda, Warrant Officer Vato Falman and Sergeant Major Kain Fuery.

"Fishing" in Central
No sooner does Mustang arrive in Central with his squad than he is hit with a new and substantial lead regarding the goings-on in Central Command; he is contacted in the dead of night by Riza, who informs him that she has just apprehended Barry the Chopper, a supposedly executed serial killer who now exists as a disembodied soul bound to a suit of armor just like Alphonse. Securing a secluded warehouse, Roy, Riza and Vato Falman interrogate the suspicious character and uncover a wealth of new information. Barry explains that he was a guard at Central Alchemical Laboratory #5, a supposedly abandoned military facility which was in actuality being secretly used to manufacture imperfect Philosopher's Stones using military personnel as researchers and live prisoners as ingredients - and had met Alphonse Elric when he and Fullmetal snuck into the compound a short time earlier. With this information, Roy is able to piece together the cryptic snippets of information that Major Armstrong had given him after Hughes' funeral and deduces that Central Command is likely behind the experimentation there as well as the sudden destruction of the facility and the evidence hidden therein. Barry also describes two individuals named Lust and Envy who appear to have been in charge of Lab 5's personnel and explains how he himself was torn from his own body and bound to his current armor form as part of the gruesome experimentation being performed there. As a final note, Roy demands to know if Barry was involved in the murder of Maes Hughes a month earlier, not noticing Riza and Falman's. When Barry responds in the negative, Roy drops the subject and asks Falman to forget everything he had heard during the interrogation. But when Falman declares that his impeccable memory will not allow such a thing and promises to follow the Colonel's path to the end, Roy uses Falman's offer as an excuse to place him as Barry's unofficial guard, setting them up to stay hidden in a safehouse nearby.

Over the next ten days, Roy begins digging into the archives at the records department, tirelessly trying to find the information that Hughes was researching before his death. He encounters Major Armstrong, who offers moral support and mentions that he had met the Elric brothers down in the south. Roy asks Alex if he had told the boys about Hughes' death and when the Major responds that he could not bring himself to do so, the Colonel lectures him for being too soft on Edward, who will be exposed to much harsher truths once he turns sixteen and becomes subject to military missions as a "Human Weapon". But when Mustang encounters Edward and Alphonse - who have recently arrived in Central to see Hughes - Roy tells the boys that Maes has retired from the military and moved to the countryside with his family. Though he tries to rationalize this lie to Lt. Hawkeye after the Elrics go on their way, Mustang is forced to acknowledge that he himself is being just as "soft" as Armstrong was.

A new development arises when 2nd Lieutenant Maria Ross, one of Major Armstrong's subordinates, is publicly charged with and arrested for Hughes' murder. Suspecting foul play in the strangely promulgated proceedings, Roy begins a counterattack to draw out the hidden enemy and orders Hawkeye to gather as much information on Ross as possible. But when the news arrives that Ross has been convicted and marked for execution without so much as a trial, the next phase of Roy's plan goes into effect. He receives a call from Barry, who - having met Ross during the incident at Laboratory 5 - is certain of her innocence and offers to break her out of jail. After securing an outside phone line away from the prying ears of his superiors, Roy orders Barry to go in, rescue Ross and help him fake her death and then sends 2nd Lt. Heymans Breda to gather the materials necessary to transmute a rudimentary mock corpse. Once he has the materials, Roy uses his basic knowledge of human anatomy as well as the information gathered by Hawkeye to fashion the corpse's form to a woman of Ross' build and matching her dental records.

With the knowledge that his old war comrade, burn specialist Dr. Knox will be on duty conducting autopsies, Roy steps out to play his part and waits for Ross' arrival along an escape route that Barry the Chopper had suggested. When she appears, afraid and confused by the sudden and unexplained events of her abduction from jail, Roy produces the corpse doll from a nearby dumpster, informing her that she is a dead woman from this moment forward before incinerating it with Flame Alchemy right before her eyes. Roy forces her into the dumpster, which has been converted into a secret tunnel entrance where 2nd Lt. Jean Havoc is waiting to escort her from the scene. Unfortunately, no sooner has the real Ross been whisked away than Edward Elric appears on the scene, furious over both Mustang's earlier falsehood regarding Hughes' murder as well as Ross' apparent demise. Mustang apologizes for keeping Hughes' death from the boys, but not for "killing Ross" and after cementing his alibi with Col. Henry Douglas of the military police, heads with the Elrics and Major Armstrong to the hospital morgue, where Knox conducts an autopsy on the corpse doll, falsifying the reports despite having recognized the body as a fake. Armstrong is significantly distraught over Ross's false conviction and death. Mustang, wishing to invite Alex into his confidence, cryptically suggests that the Major take some time off in the East Area, where he claims the women are beautiful.

With the initial phase of the plan complete, Roy returns to his office, having orchestrated leave for all of his main subordinates in order to enact the next step of his plan. Receiving word from Barry regarding the Chopper's plans to secretly extradite Ross to the ruins of the ancient eastern country Xerxes through a channel supplied by his new friend Ling Yao, Roy sends Breda to the eastern town of Resembool to await Majors Armstrong and Elric, who have been surreptitiously ordered to meet him there so that the three can sneak across the border to exchange information away from the enemy's ever-present prying eyes. Meanwhile, Havoc, Hawkeye and Fuery are covertly placed at a stakeout point observing Falman's safehouse. As Roy had suspected, the violent release of their scapegoat Maria Ross from her holding cell by their former subordinate Barry the Chopper has drawn the mysterious enemy's attention, causing them to act. While Mustang feigns nonchalance in his office, he communicates via code with Hawkeye, who informs him that a strange figure has approached Barry's location, thereby kicking off the Colonel's secret operation to "fish out" the enemy using the Chopper as bait.

Though Havoc, Fuery and Hawkeye perform admirably, Roy perceives a problem and, fearing that Hawkeye may be in danger of going the same way as Hughes, rushes madly to the scene of the battle just in time to rescue Kain and Riza from the clutches of a mysterious figure called Gluttony with his Flame Alchemy. After Lt. Hawkeye berates the Colonel for entering the battlefield and showing himself to the enemy, the two (leaving Kain and Black Hayate to erase evidence of their presence) head to the ground to rendezvous with the others, only to find that several strange revelations have taken place. Havoc explains that the strange person who had attacked Falman and Barry was in fact Barry the Chopper's human body with a lab animal's soul inside. Alphonse, who has arrived on the scene with Ling and his retainer Lan Fan, demands to go with Mustang and crew as they chase after the fleeing human shell and explains to them all that he had just encountered a familiar being named "Envy", who had transformed from a dog into the form of a human right before his eyes. Mustang is skeptical when Alphonse claims this Envy person is a Homunculus, but Hawkeye backs up his claim, stating that the creature called Gluttony would not die no matter how many times she fired into its vital organs.

To Hunt Immortals
Taking advantage of Barry's ability to sense his body's presence through his spirit, Mustang, Alphonse, Havoc and Riza tail the errant creature to Central Alchemical Laboratory #3 while Ling and Lan Fan stay behind to deal with Envy and Gluttony. At first, due to the lab's close connections to Central Command, Roy opts to end the mission here and regroup, but when Barry - crazed by the idea of being able to chop up his own body - rushes inside against orders, the Colonel decides once again to play off of the confusion and storms in afterward, announcing to the staff inside that he is pursuing a dangerous fugitive and misinforming them that backup is already on its way. The group follows the Barrys' trail to a sealed off basement level of the facility and decides to split up in order to find their quarry, Mustang with Jean Havoc and Alphonse with Lt. Hawkeye.

Mustang and Havoc reach a set of underground laboratories which appear to have been abandoned. Havoc comments that the labs stink of violence while Roy notes that the strange bloodstains on the floor as well as operating tables fitted with leather straps suggest that the research that was being performed here could not have been legitimate. Before they can investigate further, they are interrupted by a mysterious woman marked with the Ouroboros. Roy demands to know if she had anything to do with Hughes' death and the woman reveals that, while she was an enemy, she was not the one who took Maes' life in the end. Mustang shoots the woman in the leg and orders her to get down on the ground for capture and interrogation, but when her wound heals before his eyes and she claims that it will take more than that to subdue her, Roy immediately fires shots into her head and chest. Unfortunately, this does little more than confirm for Mustang and Havoc that they are dealing with the seemingly immortal Homunculus Lust that Barry had described. She opens the shrinking wound in her breast to show that, as a Homunculus, she has a Philosopher's Stone as her core which will keep regenerating all her wounds but states that she is otherwise just like a human.

Mustang deduces that Lust feels secure enough to reveal this sensitive information to them because she does not intend to let them live and declares that he will discover what she attempts to hide by keeping them even this far from the Homunculi's base of operations, but Lust reveals another of her inhuman abilities by extending her fingernails into razor-sharp blade with which she disables the Colonel's sidearm and ruptures an overhead water pipe, dousing both soldiers and eliminating Roy's Flame Alchemy as a threat. With the tables overturned, Roy and Jean flee the room, but Roy reveals that he has yet another trick up his sleeve; with the Transmutation Circle on the back of his glove and a cigarette lighter borrowed from Havoc, he transmutes the water filling the room into combustible hydrogen and flammable oxygen which he then ignites, incinerating Lust in a makeshift furnace.

Mustang and Havoc cautiously reenter the devastated room to investigate and though the Colonel comments that the Homunculus was definitely incinerated, he warns Havoc to be on alert for Lust's regenerative abilities. Unfortunately, at that very moment, the Homunculus' bladed talons shoot out from the rubble, impaling the 2nd Lieutenant through the abdomen. As Havoc falls, Roy attacks the quickly regenerating Lust, reaching into her chest cavity to pull out the Philosopher's Stone. As the Homunculus' shell begins to disintegrate without its core, Mustang declares that he will use the stone's power to heal Havoc's wound, but before he can manage, Lust's body begins to reform around the stone in his hand and she stabs the Colonel in the side with her bladed hand. Lust destroys Roy's ignition cloth gloves and leaves him to die, all the while declaring the Homunculi to be the next stage of evolution and lamenting the loss of the Flame Alchemist as a potential Human Sacrifice. Mustang calls out to Havoc, who is bleeding out on the floor, but gets no response. Fearing that all the people close to him are beginning to die before he does, Mustang firms up his resolve and cuts a Flame Alchemy circle into the back of his hand. Using the flint from Havoc's lighter, he reactivates his Flame Alchemy and uses it to painfully cauterize his and Jean's wounds shut before heading out after Lust.

Following the sounds of combat, the Colonel arrives at a spacious hall just outside a gigantic stone doorway, where Lust has begun attacking Hawkeye and Alphonse Elric. Upon hearing Al refuse the defeated Hawkeye's request to leave her behind and save himself, the Flame Alchemist makes his presence known and, signaling the armor boy to transmute a defensive wall as he unleashes the full fury of his Flame Alchemy on Lust, finally bringing her to her knees. Colonel Mustang announces, as he fires off wave after wave of flames at her, that if it will take more than a normal kill-shot to subdue her - as she had claimed before - then he will continue killing her until she stays dead. Forcing her to keep regenerating rapidly to survive his attacks, Mustang pushes Lust's Philosopher's Stone to exhaustion, causing her body and core to disintegrate to nothing before his eyes. As she dies, Lust commends Roy's resolve, but warns that the day his clear, focused eyes will become clouded by suffering is nigh.

Roy and Havoc are whisked away to the hospital where, after being given emergency treatment for their wounds, the Colonel scolds Hawkeye for succumbing to enemy taunts and losing her will to fight on the battlefield. Riza apologizes and makes up for her actions by producing a map of the city and explaining that she had counted her steps while they party was traversing the underground facility the night before, but because the hallways were slightly curved, she was unable to calculate the exact location of that large white room, and could only confirm that they had ended up somewhere within a circle she had drawn on the map with Lab 3 at the center. Complimenting the lieutenant's exceptional work, Roy gets right to the task of examining the evidence they had gathered. He notices that both Central Command Headquarters and the Führer's executive residence lie within the circle and begins to wonder whether King Bradley is an enemy or an ally. Though the path ahead seems daunting, he vows to get to the bottom of the conspiracy that Hughes had uncovered and asks Riza and Jean to continue following him loyally. Hawkeye complies wholeheartedly, but both Roy and Riza are shocked when Havoc suddenly bows out, stating that he can no longer feel either of his legs and must retire from the service.

Realizing that Havoc's paralysis was caused when Lust's fingers severed his spinal cord, Roy looks into spinal anatomy to see if there is anything that can be done for him. Unfortunately, Dr. Knox - who has come to chastise Roy for the sloppy job he did transmuting Ross's dummy corpse - informs him that a spinal injury offers virtually no chance of recovery. Breda suggests that they consult the Dr. Marcoh whom Ed and Armstrong had mentioned, prompting Roy to manipulate the 2nd Lieutenant's available leave so that he can fetch the Philosopher's Stone-carrying physician, but Breda returns empty-handed, stating that Marcoh had been abducted by the enemy before he could reach him and that his leave for the year has been all used up, confining him to Central City. Visiting Havoc in the hospital room, they discover that Jean has officially begun his discharge proceedings. Roy protests, but Jean declares angrily that the Colonel has no use for a motionless pawn and scolds him for thinking that he can make it to the top of government while wasting time pitying a fallen soldier. Roy solemnly agrees to let Havoc leave his service, but adds that he is only cutting him off temporarily and will be waiting for him when he reaches the top. Though his wounds are not yet fully healed, Roy demands to be discharged from the hospital.

Gathering Force
After discovering that King Bradley is a Homunculus, he tries to expose him to the top echelons of the military. This move costs Mustang and deprives him of his subordinates - King Bradley places Riza Hawkeye under his command and authorizes the transfer of Mustang’s remaining personnel to the far reaches of Amestris.

In chapter 69, he is contacted by Major General Olivier Armstrong through an old flower-seller, who made Mustang buy all her flowers for the information. The old flower seller, said to have served the Armstrong family for generations, revealed that Olivier is intending for the "sword" of East Area troops under Mustang's command to join with the "shield" of the Briggs mountain range troops in order to protect Briggs, and wants Mustang's cooperation. He finally manages to meet Hawkeye in person, who manages to tell him that Selim Bradley is a Homunculus. He later passes that message to Olivier Armstrong, as she takes over the residence of the Armstrong family to herself. He then meets up with his subordinates and the four attack Central's military(wounding but not killing anyone) while Fuhrer Bradley is "gone."

The Promised Day
In chapter 93-4 Mustang's gang arrives at Central. While Mustang and Hawkeye meet up with Edward, the other subordinates send out a radio transmission of how the upper brass of the military is corrupted, although they say it in believable terms and do not mention the Homunculi or their real intentions. Mustang encounters Envy, who after being questioned, reveals he was Hughes' killer. Edward, Scar, May, and the chimera all move on to get to Father, leaving Hawkeye and Mustang to fight Envy. Both parties are reminded of Mustang's defeat of Lust (whose charred remains can still be seen on the floor) using the same methods of flame alchemy and Envy, realizing that Mustang could easily kill him, attempts to escape. Mustang orders Hawkeye not to come with and goes off after Envy, but she comes anyway. During the pursuit, Envy tries to throw Mustang off guard by transforming into Hughes, but this does not fool the Flame Alchemist, who sets Envy on flames again while pointing out the fact that Hughes is dead and gone from the world, and that Envy's action has only served to add fuel to the flames. Envy than charges towards Mustang, hoping that the Flame Alchemist wouldn't dare burn him at close range, but this act backfires as well. Envy makes another dash for it when Mustang mercilessly continues to burn him, and discovers Hawkeye searching for him. He shifts into Mustang and deceives her (most likely planning to do so for just long enough to kill her) momentarily. Hawkeye, however, understands that it could be Envy and tricks the homunculus by saying that Mustang never calls her "lieutenant" but Riza when the two of them are alone. Envy falls for the trap which confirms that it was indeed Envy. She is able to take him on with her guns for a little while even with injury, however, Envy eventually is able to get the upper hand and ensnares her in his elongated arm. Just as he is about to kill her, Mustang blasts him from a side entry, and warns Envy that Riza is one of his dearest subordinates. He burns Envy one final time which causes the homunculus to revert back to his ugly parasitic form from before. He is one spark away from killing him when Hawkeye, although injured to an unknown extent, gets up and puts her gun to his head. She refuses to put her gun down and tries to persuade Mustang to stop, and he explodes at her, going into a fit of rage and refusing to give up his vengeance. Ed and Scar arrive, and Ed uses his alchemy to grab Envy; Mustang then demands that Ed to give him back.

When Edward refuses, Roy threatens to burn his arm off. Edward accepts the challenge, but asks for him to look at himself first, claiming "You think you can lead a country looking like that?!". Edward then reminds him of his goal and Mustang's temper subsides a little. Scar partially agrees with Edward that Roy couldn't lead others the way he is now, but shows no opinion if Roy does exact his revenge on Envy. Riza then asks to let her kill Envy intead, but Roy rages about his revenge for Hughes, but Riza tells him that she knows full well that he has seeked to avenge Hughes but corrects him that he only wants to kill Envy to satisfy his revenge. Riza then sorrowfully pleads for Roy to not fall like this, and Roy remembers him and Hughes when he was still alive in a photo and tells Hawkeye that if she was going to shoot, she should shoot, and then asks her what she would do if he were to die. She replies that she had no intention of living a comfortable life alone and would erase her body, and the secrets to flame alchemy which drive men mad, from this world. Finally, as it seems his anger has mostly subsided, and takes it all out on a wall with his flames, he comments about how that is troubling as he cannot lose her. He laments on his recent behavior and actions and apologizes to her for how he forced her to act.

Envy then cuts in, mocking their apology. He antagonizes everyone, bringing up events that he hopes might bring themselves to fight amongst each other and taunting others with the things they have done. Edward looks at him, pointing out Envy's envy of humans. Ed goes on to explain that, even though humans are weak, and sometimes they fail, humans have their friends to help them up whilst Homunculi don't have such a comfort. Envy frees himself of Edward and falls to the ground. Riza is about to shoot, but Scar stops her, pointing out that Envy doesn't have much time left. Envy comments on how pathetic he seems, on their "mocking nature", and how Edward, the one that he despises the most, is the only one that understands how he truly feels. He pulls out his Philosopher's Stone and crushes it, then disintegrates into dust while bidding Edward a tearful farewell. Seeing that Envy has committed suicide, Roy calls him a "coward".

They continue their path through the subterrain but get lost, being separated from May, who was guiding them. Walking down a path, they find the Doctor who had created all the candidates for Führer and King Bradley himself. Activating a transmutation circle, he makes Ed disappear in front of their eyes, ensuing a fight between Mustang, Hawkeye and Scar against those failed attepts of creating the homunculus Wrath. The failed Führers subdue the three and the doctor tries to force Mustang into performing a Human Transmutation and becoming a qualified human sacrifice. Mustang refuses and one of the failed Führers slice Hawkeye's throat, leaving her to die. The doctor says he can cure her, but only if Mustang obliges to make a Human Transmutation. Mustang considers doing what he's told in order to save Hawkeye, but she sends him an eye signal in order to stop him, as May and the chimeras join them, resuming the fight. May staunches Hawkeye's bleeding with Xing alchemy, but Wrath and Pride arrive. Wrath then pushes Mustang into an alchemy circle by pinning his hands to the ground with swords. He is made the fifth sacrifice needed by Father.

In Chapter 102, Pride uses the Gold-Toothed Doctor to open the Gate of Truth forces Mustang into it. What happens while Mustang is at the gate is unclear, but as he leaves, he is transported to the room where Ed, Al and Izumi were taken before. Ed tries to talk to him, and Roy replies that he cannot see; the Truth has taken his sight as the price of looking inside the gate. Pride arrives at the scene and Father discusses the irony behind the works of the 'Truth', who took Ed's way to 'stand by himself' and his 'only family', Al's body so he 'cannot feel the mother's warmth as he craved', Izumi's 'capacity to bear a child' and, now, with Mustang, coming full circle, 'depriving the man who had a grand vision to save his country from his eyesight, denying him to see what his beloved nation will become'.

In Chapter 105, after the Alkhestric Reverse is activated, Edward, Alphonse and Izumi launch their final attack against Father. Roy expresses his frustration and shame that he's useless at such a key battle, later asking Hawkeye if she can still fight, to which she replies she can.

In Chapter 107, however, he joins the fight with Riza at his side. He is shown to be able to use his Flame Alchemy via clapping, but with the downside that he cannot really keep it safely under control without his sight. He also is relying on Riza to properly aim his attack and warn him of Father's counter attacks. Unfortunately, when their combined efforts contribute to Father's loss of composure, the blowback from the energy he released renders everyone but Edward incapacitated. As such, while Edward takes the initiative onto his own shoulders, Roy joins in by shouting out his support to his friend and ally.

After the battle with Father is over, Roy is shown in a medical center conversing with Dr. Knox. He informs the doctor of his disability, and states that he will have to retire. He decides to pass the title of Fuhrer over to Grumman. Knox then informs Roy that Dr. Marcoh was looking for him and brings the doctor over to Roy. Marcoh informs Roy that he has a Philosopher's Stone which Roy could use to regain his eyesight. Roy initially refuses, but Marcoh say that he has a plan in which they and the Ishvalans (referring to the souls in the Philosopher's Stone) can work together. Marcoh says he'll hand the stone over on the condition that Roy changes the Ishval policy, allows the Ishvalans to return to their homeland, and allow him(Marcoh) to live in Ishval as a doctor. Roy agrees to Marcoh's demands. Two years later, it is mentioned that Mustang has been promoted to Brigadier General and is working hard on rebuilding the Ishval region as well as turning it to a trading point between Amestris and the country of Xing. At the epilogue, it is shown that he is promoted to General and is still with Riza Hawkeye. He also appears to have regained his eyesight as well.

2003 Anime
Mustang makes his first appearance in the series in To Challenge the Sun (episode 1), when the Elric Brothers attempt to resurrect their mother. Subsequently, Mustang is formally introduced in Mother after Alphonse brought Edward to the Rockbells' home. As a lieutenant colonel in the State Military, he came to the Elrics' hometown of Resembool in search of their father, Hohenheim. It is also implied that Roy was seeking out Winry Rockbell, the girl he had orphaned during the Ishval Rebellion, in order to see how she was doing That Which is Lost. Recognizing Edward and Alphonse's talent for alchemy, he offered them a chance to become State Alchemists and to seek him out at Central City, where he was currently stationed.

Athough appearing in episode one, the first time he speaks is in episode three "Mother" albeit only one sentence.

The Elrics take up his offer and Edward reluctantly becomes his direct subordinate when he becomes a State Alchemist. Mustang is transferred to the Eastern Territories to clean up Lieutenant Yoki's mess (Episode 9) and is promoted to colonel. He remains at Eastern Headquarters for the early portions of the series until he is transferred back to Central after Hughes' death.

In episode 15 (Ishbal Massacre) it is revealed that Roy had executed Winry Rockbell's parents in place of Scar in the manga. He was devastated by his cold-blooded actions and tried to kill himself, but to Hughes, Edward, and his subordinates, Roy explains his failure to do so by saying that he "was too much of a coward" to pull the trigger. Instead, Roy decides that he is going to work to reach a position where he would not have to obey orders like that: becoming the Fuhrer.

When Hughes dies, Mustang is devastated. When pursuing the Elrics after the Stone's creation in Liore, Mustang learns that the Führer is a Homunculus, and tries to expose him to the top brass of the military by revealing the truth about the Führer's secretary, Juliet Douglas (Episode 45).

Although Bradley intends for him to die in combat during the Northern Campaign by sending him and Armstrong to the front lines, Mustang instead stays in Central, making his move to avenge Hughes' death. He explains his actions to Edward in the end of Goodbye, saying that he has given up his goal of becoming Fuhrer to avenge Hughes because Hughes' life is more important to him, much like Edward has given up restoring Al with the Stone, because to Ed the lives of the people who went into the Stone's creation are more important. He points out his and Ed's similarities in the scene, and Edward finally comes to respect and understand him. Roy then moves on to the Fuhrer's mansion and stages his fight. Mustang is only able to defeat King Bradley when Bradley's son, Selim, unwittingly brings the skull of the man from which the Führer was created and weakens Bradley, who then in a rage snaps Selim's neck killing him almost instantly.

As Mustang escapes the Führer's burning mansion, he is confronted by a maniacal Frank Archer, who shoots him leaving his face in a pile of blood. Hawkeye arrives in time to save him and kills Archer.

It is then revealed that Roy loses an eye from being shot by Archer but keeps an optimistic attitude. When Hawkeye despairs at him that she should have been there to stop Archer, Roy says that "the world's not perfect" and that's what makes it so beautiful." He seems to not be unhappy with what transpired in the Fuhrer's mansion, and that the loss of his eye only showed that "nothing is ever perfect."

He has a cameo in a later episode in which Envy shapeshifts into him in a failed attempt to guilt trip Ed into keeping him alive. When he does this, Ed laughs and shouts "You couldn't have picked an EASIER target!"

Fullmetal Alchemist: Conqueror of Shamballa
In Conqueror of Shamballa, Mustang resigns from both alchemy and his rank to become an ordinary enlisted man in a remote outpost. The events of the series are shown to have taken a heavy toll on Roy, since he says he has not used his alchemy since killing Fuhrer Bradley; Roy says that he can still see the people he had killed in Ishval with his blinded eye. However, when Central is under attack by armies and airships, Mustang steps up and takes command, using his alchemy to defend Central. Mustang and Armstrong are able to find a hot-air balloon to reach the airships, where he is reunited with the Elric brothers, and helps them gain entry into the airship. Roy is glad to see Edward alive and well, and it is implied that it is Roy seeing Edward again that galvanizes Roy into taking charge and giving orders and using his alchemy again. When Edward leaves, he is the one to hold Alphonse back but he lets Al go in order for the younger Elric to follow his older brother. At the end of the movie, Al says that Mustang and his team are now responsible for destroying the Amestris side of the Gate.

Trivia

 * A Salamander can be found in Flame Alchemy emblem and transmutation circle. In ancient Greek mythology the salamander was considered the living symbol of fire and as such was completely fireproof and able to live in fire itself.
 * In compliance with his womanizing fame (or perhaps in exploitation of it), Roy codes his research notes with the names of women, making them look like a mere record of his romantic adventures.
 * In the OVA "Kids", the young lookalikes of Edward, Alphonse, and Winry pass by a group of kids playing cards on a sidewalk. The kids resemble some of Mustang's men from the series, and one of them looks notably like a child version of Mustang.
 * While all original art for the manga and both anime series depicts Roy Mustang with black eyes, a few recent manga color pages show Roy with blue eyes, presumably to better portray him in moments of emotional and/or physical duress.
 * The eye Mustang lost after his battle with Pride - in the 2003 anime - was his left eye, coincidentally the one Pride wore an eyepatch over and the one that Archer had a cybernetic one inserted, both people having been people he confronted in that same episode.
 * Mustang's English voice actor, Travis Willingham, also plays Portgas D. Ace in the Funimation dub of One Piece, the user of the Flame Flame Fruit. As well as playing Johnny Blaze, the Human Torch in "Marvel Super Hero Squad" for Cartoon Network.
 * Colonel Roy Mustang's commitment to a coup d'état against the Führer, and the symbolic loss of his left eye are eerily similar to the exploits of a World War II German Resistance member, Colonel Claus von Stauffenberg, who attempted to kill Hitler in a Resistence operation called Valkyrie. Colonel Stauffenberg also lost his left eye.
 * The relationship between Riza and Roy is a heavily implied one, and fans refer to their relationship as "Royai", The first part of "Royai" Roy is his name, and the end "ai" means love.
 * Lt. General Grumman once asked Mustang if he would marry his granddaughter saying she would be the future Fuhrer's wife; Mustang told him not to think too far ahead (it was revealed in perfect guidebook 2 that Grumman's granddaughter is in fact Riza Hawkeye. Whether Mustang was aware of this when the General made the offer is unknown).
 * Like nearly all military personnel in the Fullmetal Alchemist series Mustang is named after a military vehicle, vessel or weapon, in his case, the P-51 Mustang, a American fighter aircraft used by the allies (specially the brittish RAF) in WWII. This aircraft is considered by many to be "the best fighter aircraft in WWII".
 * Mustang's record for playing chess with Grumman is 1 win, 97 losses and 15 draws.
 * Mustang names all of his subordinates after chess pieces, with connotation of battle ability and usefulness to him. Fuery is the "Pawn", Falman, the "Bishop", Havoc, the "Knight", Breda, the "Rook", and Hawkeye, the "Queen".
 * Roy Mustang bears a facial resemblance to Ryuukou from Hiromu Arakawa's other series, Hero Tales (Juushin Enbu).
 * Arakawa said in the Q&A section in Guidebook 3 (Character Guidebook) that the car Roy drives in the series is actually his (and not a military car) and that he lives in a narrow rent house in Central. She says he owns little more than a couch in his living room.
 * Though several fans have likened Roy's eyes to those common Xingese immigrants, there has been no indication that Roy is of full or partial Xingese ancestry.
 * Roy is the second most popular character in the series, as shown in the latest fan poll as well as the previous ones. However, this angers him to the point of wanting to burn Edward for being the most popular.
 * Roy is the only character in FMA to be forced to open the Gate.
 * Roy and Ed was referenced in the anime Lucky Star along with Apollo Justice and Klavier Galvin from the Phoenix Wright/Apollo Justice series.
 * Roy almost always snaps his starter gloves with his left hand. It is unknown if he is left handed, ambidextrous, or just simply prefers starting with that hand.
 * It is interesting to note that Mustang's 2009 seiyu, Shinichiro Maki, voiced Lockon Stratos (I) from Mobile Suit Gundam 00 who also lost his left eye and even wears an identical eyepatch.

Quotes

 * (To Edward after seeing the gate) "I... can't see..."
 * (to Dr. Knox after the final battle) "I can't see a thing. Its a punishment to those who dream... or so I'm told. I wish I could do so as Fullmetal did and use my own gate as a toll, but then there wouldn't be a way back. My eyes were taken. There's nothing I can do about it."
