Karl Ernst Haushofer (カール・ハウスホーファー) is a villain of the Fullmetal Alchemist movie Conqueror of Shamballa. He was a German general, geographer, and geopolitician. Through his student Rudolf Hess, Haushofer's ideas may have influenced the development of Adolf Hitler's expansionist strategies.
After retiring from the German army, Haushofer became a professor at the University of Munich in 1921. There he meets Hohenheim for the first time, who recently had installed in the city. Confessing to having a great knowledge of alchemy, Hohenheim earns the respect of Karl and in the someway both are shown, in the last episode from the 2003 anime, to participate in a secret organization called Thule Society.
