On the way to Lior, Ed and Al reminisce about the events that lead to them being trapped in their current bodies by breaking the taboo of human transmutation. Meanwhile, Colonel Mustang looks back on the first time he met the Elric brothers.

Ed and Al arrive at the city of Lior, hoping to find the legendary Philosopher's Stone so they can return their bodies back to normal. There, they meet a priest named Cornello, who is able to perform "miracles." As Ed and Al investigate, they find out the truth about Cornello.

Ed and Al become interested in biological transmutation after witnessing a chimera in Lior, so Colonel Mustang introduces them to an expert in the field, Shou Tucker, the Life-binding Alchemist. Meanwhile, a serial killer whose targets are only State Alchemists is on the loose in Central.

After learning about what happened to Shou Tucker and his daughter Nina, the Elric brothers begin to question what alchemy really is. Meanwhile, Colonel Mustang and the other State Alchemists track down the serial killer Scar.

After their encounter with Scar, Ed's automail and Al's armor need to be repaired, so Major Armstrong escorts them to their hometown of Risembool. On their way there, they spot Dr. Marcoh, a scientist who helped create the Philosopher's Stone, and try to convince him to give them the location of the Stone's research data.

When Ed and Al arrive at the Central Library they discover that it has been burnt to the ground and instead are taken to see Sheska, a former employee who may have the information they seek. Meanwhile, in East City an unexplained explosion causes Colonel Mustang to restart his search for Scar.

Ed and Al sneak inside the Fifth Laboratory to search for more answers about the origins of the Philosopher's Stone. However, it is not long before they are each attacked by former death row murderers who now guard the complex.

Ed is now in a hospital recovering from his wounds and Al is unable to let go of what Number 66 told him back at the Fifth Laboratory. Meanwhile, Winry agrees to make a trip to Central in order to repair Ed's automail... again!

When the conspiracy surrounding the Philosopher's Stone closes in on the highest ranks of the military, one of Mustang's most trusted and cherished allies is murdered.

The Elrics, realizing alchemy has yet to unlock the mysteries of creating life, feel powerless when a new friend goes into labor. Winry, however, jumps into action with a young thief named Paninya.

While visiting Izumi, their childhood teacher, the Elrics recall the early difficulties of grasping equivalent exchange. They also discover she shares their intimate knowledge of alchemy's greatest taboo.

Al is abducted by chimeras led by the seemingly indestructible Homunculus known as Greed. When Ed's rescue attempt falls short, Izumi proves once more that she's got the brothers' best interests in mind.

The Elrics scuffle with Ling Yao and his attendants, Lan Fan and Fu, visitors from Xing seeking the Philosopher's Stone. Ed may not like him, but Ling Yao's not leaving until he gets what he wants.

After learning of Hughes's fate, Ed and Al are ravaged by sadness and guilt. Envy still hides in plain sight among the State Alchemists, and another Homunculus is on the verge of infiltrating their ranks as well.

Freed by an unlikely liberator, Ross's escape is interrupted by Mustang. Even those most loyal to the Flame Alchemist are shaken by the controversial action he takes against the accused killer of Maes Hughes.

Ed's journey to a distant land of legend offers surprising new details behind Mustang's alleyway encounter with Ross. After a fateful encounter of his own, Elric learns a stunning secret about Winry's parents.

Mustang, Alphonse, Havoc, and Hawkeye split up to search a military laboratory. If Lust has her way, none of them will ever see each other alive again.

Hohenheim's visit ends with a grave warning to Pinako, but Ed finds hope among the charred ruins of his childhood. Now more than ever, he has confidence that Al can be returned to his body.

Hoping to learn more about the Homunculi, Ed and Al devise a risky strategy to lure the creatures out of hiding. Step one of the brothers' plan: risk death at the hands of their most dangerous enemy - Scar.

Scar's mission to destroy those who slaughtered his people is fueled by justifiable rage. Upon learning the role Scar played in her parents' deaths, Winry claims those murderous feelings as her own.

Cooperation between Mustang's cabal and Ling Yao's band leads to the capture of a Homunculus. Unfortunately, their actions also capture the eye of the Homunculus hiding atop the military's ranks.

Gluttony's twisted powers overwhelm the Elrics - and the creature's appetite is satisfied by battle's end. Meanwhile, Mustang acts on his suspicions of Bradley and finds himself in the belly of the beast.

The Homunculi are winning. Ed and Ling face a horrific enemy within the hellish expanse of Gluttony's gut. In Central, Mustang can only watch as his loyal band of soldiers is divided by Bradley.

Visions of the past play out by a warming fire as Hohenheim reflects on the unavoidable follies of man: the pain that comes with a loving family; the hidden truths of alchemy; and the roots and results of war.

The Elrics are at Bradley's mercy; if the brothers make one wrong move, those dearest to them will pay. As Mustang quietly gathers allies at his side, Ed discovers there may be no need to find a Philosopher's Stone.

As Edward hears Hawkeye's tale of a time when idealistic young soldiers were tasked with genocide, the horrors of the Ishvalan battlefield are revealed.

Even as his subordinates are scattered, Mustang finds he still has allies - unfortunately, so do his enemies. The Homunculi unleash one of the Ishvalan War's most notorious killers to deal with Scar and Marcoh.

A secret encounter allows Mustang to spark new ambition in an old friend - an ally with loyal troops at his command. Meanwhile, Ed and Al share a chance meeting with their biggest fan - young Selim Bradley.

The frigid northern borderlands become a battlefield when Kimblee finally closes in on Scar. Deeper into the frozen wasteland, Ed and Al's fight is against the bitter elements as they struggle to reach Fort Briggs.

The soldiers at Fort Briggs remain ever vigilant against the threat of spies from Drachma. The massive compound may seem impenetrable - but a violent intruder offers destructive proof to the contrary.

Ed uncovers a conspiracy of staggering scope: a plot that has already claimed countless victims. Clues suggest that Fort Briggs will soon know bloodshed - and an entire nation will suffer.

As Raven tries to corrupt Armstrong, Ed and Al can only wait in their cell. Long ago, their father faced his own captivity, confined to an eternity of regret in an undying body. To escape the pain, he said goodbye.

Hawkeye is shocked when the first Homunculus reveals itself. Far away, Edward is surprised by an offer from Kimblee: Fullmetal can have all he has searched for - in exchange for becoming a mass murderer.

When Scar is cornered by a pair of gruesome chimeras, the Elrics enter the fray as his unlikely allies. Later, Winry's attempt to confront Scar over his role in her parent's death ends in disaster.

Bound by more than blood, the Elrics have long shared joy and pain. Now, with Al wandering the frigid void - and Ed losing blood by Kimblee's hand - the mystical connection of their souls could prove fatal.

In the snowy north, the soldiers of Fort Briggs engage an invading army, and Marcoh leads an attack against monstrous Envy. In Central, an ominous and shocking secret is revealed to Olivier Armstrong.

Hohenheim and Alphonse enjoy a chance to get reacquainted. Their bond is restored with ease, inspiring the father to share his secrets with his sons - but one of them is far away and on the run.

Quiet warnings spread near and far: the Promised Day is at hand. While most will face the coming chaos with their own kind, Edward forms a new cabal comprised of human, chimera - and Homunculus.

A sinister voice rings out from the shell of Al's armor, and Ed and Greed find themselves under attack. As the Homunculi use the darkness to their advantage, a face from the past arrives to join the battle.

With his father's help, Al takes incredible steps to contain the monstrous Pride. As the sun begins to rise on the Promised Day, the youngest Elric listens while the Homunculus ponders his very human mother.

Mustang leads a ragtag assault force of hardy northern troops - and welcome faces from the past - against Central's defenses. Victory seems certain until the military's most horrifying secret is revealed.

Ed's crew faces a horde of ravenous mannequins, abominations powered by human souls. The twisted creatures aren't the only unstoppable force on the battlefield -Pride, Sloth, and Envy are on the move.

With a Philosopher's Stone in his possession, Alphonse fearlessly engages Pride and Kimblee. Elsewhere, the Armstrongs find themselves trapped between Sloth's onslaught and the guns of Central's troops.

After a startling radio broadcast grants Mustang's forces the advantage over Central's troops, the Flame Alchemist unleashes the brutal power of burning hatred in the battle against the killer of Maes Hughes.

The battle for a nation's soul descends into chaos. Bradley unleashes death on those who dare engage him. Beneath Central, the one responsible for the Fuhrer's creation unleashes something far, far worse.
