He Who Would Swallow God
Everyone closest to the center of Father's nationwide transmutation circle, including Ed's group, survives to discover that Father has used the souls of over fifty million Amestrians to suppress God within a new, youthful body. Father neutralizes everyone's alchemy, but, before he can annihilate them, Hohenheim reveals his countermeasure: he had spent years traveling the country, placing fragments of his own Philosopher's Stone into the earth to use as foundation for returning the Amestrian souls to their bodies. The stone fragments are activated by the eclipse's umbra, and the souls are ripped from Father's body back into their original bodies, which weakens Father to the point of barely being able to suppress God anymore. The eclipse then lifts, blinding Bradley with sunlight and allowing Scar to kill him. Scar activates the nationwide alkahestry circle his brother and fellow Ishbalans had been preparing, which restores everyone else's alchemy at their greatest potential. Facing the full strength of his opponents' attacks in his unstable body, Father retreats aboveground to find more souls and replenish his stone supply. Ed remains behind to fight Pride while everyone else chases Father. Pride tries to steal Ed's body to replace his own unstable one, but Kimblee's soul reappears within him and taunts him while Ed enters his body and destroys it, reverting him to the form of a small fetus-like creature. Ed spares Pride's life and leaves to join his friends.

Fullmetal Alchemist: Brotherhood
"In order for something to be obtained, something of equal value must be lost."
Alchemy is bound by this Law of Equivalent Exchange—something the young brothers Edward and Alphonse Elric only realize after attempting human transmutation: the one forbidden act of alchemy. They pay a terrible price for their transgression—Edward loses his left leg, Alphonse his physical body. It is only by the desperate sacrifice of Edward's right arm that he is able to affix Alphonse's soul to a suit of armor. Devastated and alone, it is the hope that they would both eventually return to their original bodies that gives Edward the inspiration to obtain metal limbs called "automail" and become a state alchemist, the Fullmetal Alchemist.
Three years of searching later, the brothers seek the Philosopher's Stone, a mythical relic that allows an alchemist to overcome the Law of Equivalent Exchange. Even with military allies Colonel Roy Mustang, Lieutenant Riza Hawkeye, and Lieutenant Colonel Maes Hughes on their side, the brothers find themselves caught up in a nationwide conspiracy that leads them not only to the true nature of the elusive Philosopher's Stone, but their country's murky history as well. In between finding a serial killer and racing against time, Edward and Alphonse must ask themselves if what they are doing will make them human again... or take away their humanity.
