- —Baron Zemo[src]
Baron Heinrich Zemo , Ph.D, was the 12th Baron Zemo, a title of German nobility. His family pledged his loyalty and service to the German Empire in return for Castle Zemo and land that they could pass to their heirs. He became a scientist working for the Nazi's during World War II. His hood was permanently affixed to his head due to immersion in Adhesive X. He escaped to South America following the war to continue his experiments. He survived to the modern age, forming the Masters of Evil, a team of villains created to take down the Avengers, but which ultimately failed, leading to his death.
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. He served as a soldier during World War I.
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. In 1933, Zemo travelled to the United States to meet Dr. Nikola Tesla. He used his research to help develop Teleforce, his powerful laser weapon.
On the outbreak of World War II, Zemo quickly became one of the Nazis' top scientists and the most wanted Axis agent. In November 1941, Zemo arrived in Tunisia to help his fellow Nazi operative Baron Wolfgang von Strucker against the U.S. Army. Here, Zemo first met Captain America and Bucky.
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. 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.
Also in 1942, Zemo 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.
Zemo was working on his invention known as Adhesive X when 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 was consumed with a violent, insane hatred for Captain America and mankind in general.
Captain America and Bucky helped 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. The same year, 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.
Later that year while in Austria Zemo captured and dissected the first Human Torch to learn the source of his powers. He used his artificial DNA to create his own army of Inhuman Torches. He sent a squad to attack the Invaders. The time travelling Thunderbolts helped defeat the creatures by trapping them under a snowfall and tearing them apart. They then went and rescued the Torch and destroyed Zemo's lab. Zemo led many missions of sabotage and terror against the Allies, often clashing with Captain America.
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 they were captured by Zemo. Zemo then launched the plane, and when the heroes chased after it, Bucky was apparently 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.
Resurgence and Death
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. 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). Their scheme to turn Thor against the other Avengers failed, as did their plan to use Wonder Man as a pawn to try and gain their trust. 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 in various crimes.
While his Masters battled the Avengers, Zemo captured Rick Jones, then acting as Cap's partner. Cap and Zemo dueled in South America. Blinded by the glare from his opponent's shield, Zemo fired his death ray wildly, causing a rock slide that resulted in his death. Heinrich was survived by his son Helmut, who would try to get revenge on Captain America, and eventually adopted the mantle of Baron Zemo.
Legion of the Unliving
Following a clash with the Avengers, the time-travelling villain Kang assembled the Legion of the Unliving, a group of presently-deceased people pulled from time a moment before their deaths, including Baron Zemo. After being tasked with guarding Kang's prisoners, Immortus and Rama-Tut, Zemo confronted Hawekye. After being freed by the Avenger, Immortus devolved Zemo into protoplasm. Immortus proceeded to reverse Kang's actions, erased the memories of the battle from the members of the Legion, and sent them back to their moments of their death. He originally intended to omit Zemo, until Hawkeye convinced him to have the Baron returned to normal.
During Hercules' journey to the underworld of Hades, Baron Zemo was seen gambling for his resurrection. He was later seen as a member of Pluto's jury alongside Nessus, Orka, Armless Tiger Man, Abomination, Jack O'Lantern, Scourge of the Underworld, Cobalt Man, Kyknos, Artume, and Veranke for Zeus' trial.

- In his original appearance in 1964, Zemo had been living in South America for less than 20 years, so no explanation was needed for his survival from World War II.
