Alfons Heiderich is a character exclusive to the Fullmetal Alchemist the Movie: Conqueror of Shamballa which concluded the story of the 2003 anime series. He is a young German rocket scientist whom Edward Elric meets after being sent over to 1921 Munich. The two studied rocketry under Dr. Herman Oberth in Rome and when they returned to Munich Heiderich let Ed board with him after Hohenheim's disappearance. Easygoing and kind-hearted, Alfons enjoys hearing Ed's stories about coming from another world, but doubts their truthfulness and is hurt by Ed's eagerness to leave and his assumption that this world and its people are just a waking dream.
Though Heiderich helps Ed shelter the Roma girl, Noah, from the Thule Society, he readily accepts Thule's offer to sponsor his research and projects despite his disagreement with the racist concept of an "Aryan Race". Heiderich has reason for wanting to complete his dream of proving his country's scientific worth as soon as possible as he is succumbing to a fatal lung disease.
Heiderich neither knows nor believes that Thule is planning to use his research projects to invade and plunder Ed's world - leading to an intense confrontation where he reveals his sickness- until he sees it for himself. After reminding Ed that he and this world are real and not just a dream, and asking that he not forget him, Heiderich then helps his reluctant friend return home by sending him back through the opened Gate in a two-seater rocket, but is shot to death by Rudolph Hess, who would later be caught in plotting the tragic genocide of The Holocaust.
When Ed decides to return back to this world, he is shocked and saddened to find Heiderich's body cradled in Noah's arms, having known that Heiderich was shot in his chest. During Heiderich's funeral, Edward, his brother Alphonse (having went through the gate to remain with his brother), Noah, Maes and Gracia Hughes's counterpart and others are seen celebrating their dead friend.
- By his name and appearance, it is obvious he is the counterpart of Alphonse Elric, Edward's brother.
- It is never said which illness Alfons was suffering from, however, given his symptoms, it is likely that he contracted a form of lung disease from breathing in rocket fumes and the air pollution the fumes caused, as well as the air pollution of the age.
- His English voice actor, Jason Liebrecht, also voices Karley in the 2009 anime series.
