Upheaval in Central
As Team Mustang and Mrs. Bradley gets cornered by Central soldiers, Team Charlie, Mustang's old Ishbal squadron, intervenes and saves them. Team Mustang continues their attack on Central without killing anyone. Meanwhile, the Briggs soldiers lead by Buccaneer join the battle. Soon Team Mustang begins to run low on ammo, and they are saved by an ice cream truck driven by Rebecca and Maria Ross. Mustang calls whoever ordered Ross to return from Xing, and he is surprised to hear Havoc at the other end. During all of the chaos, Ed's group manages to sneak in underground through the Third Lab, where they split up. Ed, Scar, Darius, Zanpano, and Jelso go in one direction while Hohenheim and Lan Fan go in the other direction. However, at that moment, one of the Generals awakens the Army of Immortals.

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.
