Early Life

Heinrich Zemo (Earth-616) 0001

Baron Zemo

Baron Heinrich Zemo was born in 1900, the 12th Baron Zemo. He lived most of his life at Castle Zemo in Zeulniz, Germany. He received the very best education, excelling in science. Becoming one of the leading scientific minds in Europe.[1][2]


Heinrich was a soldier during World War I.[1][2]


Zemo joined the Nazi Party early in its existence. It was during this time that he met and married a woman named Hilda together they had a son Helmut. He was at first a loving husband and father, but this would change overtime.[1][2]

In 1933, Zemo travelled to the United States to meet Dr. Nikola Tesla. He used his research to help developed Teleforce his powerful laser weapon.[3]


On the outbreak of WWII, Zemo quickly became one of the Nazis' top scientists and the most wanted Axis agent.[1][2]


One of his first public activities occurred when Allied Sergeant Nick Fury and his Howling Commandos invaded Zemo's castle to destroy Zemo's "death ray" in 1942. Zemo was defeated, but managed to escape.[4] However, the defeat left him vilified throughout the world, and even in Germany, where Zemo took his wife and son, Helmut, into hiding. Zemo began wearing a cowl to disguise himself.[5]

Also in 1942 he acquired a sample of Vibranium that had accidentally been transported to the past from the Baxter Building. The Fantastic Four traveled back in time and teamed up with the Invaders who defeated him and returned the sample to its proper time.[6][7]

Zemo was working on his invention known as Adhesive X when the hero Captain America invaded his laboratories. In the course of destroying the only supply, the adhesive covered Zemo's cowled head, which became permanently affixed. As a result, Zemo became consumed with a violent, insane hatred for Captain America and mankind in general.[8]


Captain America and Bucky helps Baroness Hilda Zemo find Baron Zemo in 1943. He has built the Medusa Effect , which is a massive weapon capable of decimating the United States Air Force. [3]

In 1943 Zemo faced the hero Citizen V in Poland, and strangled him to death with his own hands in order to break the spirits of his followers, the V-Battalion.[9]

Zemo led many missions of sabotage and terror against the Allies, often clashing with Captain America.

Baron Zemo and Baron Strucker battled Canadian soldier Logan and Captain America.[10]


In 1945, Zemo was issued orders from the Red Skull to sabotage an experimental drone that was planned to be launched from an island on the English Channel. Captain America and his sidekick Bucky tried to stop such plan, but failed. Zemo launched the plane, and when the heroes chased after it, Bucky was killed when a bomb Zemo had placed aboard the plane exploded, and Captain America was thrown into the ocean which led him into a period of suspended animation.[11][12] [13][14]

Captain America and the Avengers travelled back in time using Doctor Doom's Time Machine. They witnessed Baron Zemo's battle with Cap and Bucky, but were unable to change anything.[15]

Post War

Heinrich Zemo (Earth-616)

Baron Zemo

Soon after, Zemo left Germany (and his family) in the final days of the war, hiding away in a base he had constructed in the South American jungle.[11]

Masters of Evil

Over the following decades, Zemo constructed a device to use his death ray against entire cities. About the same time, Captain America re-appeared, joining the super-team called the Avengers.[11] Zemo created his own team of super-villains, calling them the Masters of Evil, in order to destroy the Avengers, but they failed. He recruited Amora, the Enchantress, Skurge, the Executioner, Radioactive Man, Melter and Black Knight (Nathan Garrett).[16]Their scheme to turn Thor against the other Avengers failed.[17] as did their plan to use Wonder Man as a pawn to try and gain their trust.[18] The team also assisted by Immortus[19][20]. Finally, Zemo had his Asgardian allies free Black Knight and The Melter from jail (though Radioactive Man had been deported to his native China.) He joined them on various crimes. [21] [22] [23][24][25][26][27][28][29]


While his Masters battled the Avengers, Zemo had captured Rick Jones, then acting as Cap's partner. Cap and Zemo duelled in South America. Blinded by the glare from his opponent's shield, Zemo fired his death ray wildly and died in the ensuing rock slide.[30] Meanwhile, the remaining members were defeated by the Avengers after Thor transported them to another dimension so their battle would not destroy the city of New York.[31][32]

Power Man

Erik Josten, an agent for Baron Zemo before he died, returned to the machinery used to create Wonder Man. There he finds the Enchantress, who tells him she will use the machine to make him strong too. He agrees and is given the name "Power Man". [33]

Helmut Zemo

Baron Helmut Zemo, the son of Heinrich took over his father's mantle and tried to get revenge on Captain America.[34]


When Deadpool and Bullseye first crossed swords they battled in Baron Zemo's tomb. During the fight Bullseye attempted to strangle Deadpool with Zemo's large intestines. [35]

Legion of the Unliving

Baron Zemo is later recruited into the Legion of the Unliving.[36][37][38][39][40]

The Vision and Scarlet Witch see Baron Zemo and other villains in the Land of the Dead. [41]

Baron Zemo's corpse is later temporarily reanimated by his son and the Batroc's Brigade.[42]

The Red Skull used the Cosmic Cube to warp reality bringing back various deceased heroes and villains including Baron Zemo.[43]
