In the penultimate collection of Fullmetal Alchemist: Brotherhood, the filmmakers begin drawing together the various plots, building to the final confrontation between good and evil. In a flashback sequence, viewers learn the origins of both Hohenheim and his doppelganger, the "Father" of the Homunculi. Hohenheim was once No. 23, a slave of an alchemist in Cselkcess, who created the first Homunculus. When the King of Cselkcess's attempt to achieve immortality backfired, Hohenheim became "a human Philosopher's Stone" and the Homunculus created a body for himself that was a duplicate of Hohenheim's. Decades later, the Promised Day is at hand: "Father" plans to activate the countrywide transmutation circle, killing untold thousands to create an enormous Philosopher's Stone--and activate the "Mannequin Army," a corps of deathless zombies animated by the Stone's power. But even supernatural plans can go awry. Lust was destroyed by Colonel Mustang; Pride, in the guise of Selim Bradley, devours Gluttony. Greed, who took over the body of Prince Ling Yao of Xing, has joined forces with the Elrics; Wrath, a.k.a. Fuhrer Bradley, is missing, leaving Pride, Sloth, and Envy. Pitted against them are an interlocking series of alliances that include the Elric Brothers and Hohenheim; Dr. Marcoh, Scar, and May Chang, with their knowledge of the Alkahestry of Xing; and Colonel Mustang, Alex and Olivier Armstrong, and their loyal soldiers.
