Erik Jan Hanussen is a villain of the Fullmetal Alchemist movie Conqueror of Shamballa. He was a clairvoyant who instructed Adolf Hitler in performance and the achievement of dramatic effect (despite being Jewish).
He only appears during a scene at the carnival where he meets Noah. The other female Gypsies give her to Erik so he can hand her over to the Thule Society. She is able to escape from the men and hid underneath a cloth covering Ed and Alfons' rocket on the truck they arrived in.
- Erik Jan Hanussen mirrors his Amestris counterpart Frank Archer, who is also a charismatic liar.
- Both Erik and Frank are both voiced by Troy Baker for the English dub, however, Erik's original voice is Toshio Furukawa and Frank is voiced by Show Hayami.
- In the real world events, Hitler used Erik to teach him how to captivate a crowd. While Erik began to predict events that would help the German people to listen to him. After the Reichstag fire (which was considered one of Erik's most famous feat of clairvoyance), Erik was shot to death by an unknown Nazi assassin on March 25th, 1933. The order must have come from Hitler after it was discovered that Erik had lied about his origins as a Moravian Jew.
