Fullmetal Alchemist, Vol. 14 - Hiromu Arakawa

Ed and Al come face to face with the father of the homunculi, who happens to be a dead ringer for their own father, Van Hohenheim--a resemblance too uncanny for coincidence. And later, when the allure of immortality proves to be too much for Prince Lin of Xin, he lets Greed take over. Young adult.
