Heinrich Zemo (Earth-616) 0003

Baron Zemo in the lab.

Baron Heinrich Zemo was born in 1900, the 12th Baron Zemo. He was one of the most brilliant scientists of Nazi Germany, and joined the Nazi Party early in its existence. Zemo quickly became one of the Nazis' top scientists and the most wanted Axis agent.

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.[1] 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 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[2].

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.[3] Hilda soon turned against him, and she died during one of his battles against Captain America. 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.

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 plane in England. 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.[4] 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.

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.[5] Zemo clashed with the Avengers several times after that[6][7], including an attempt to destroy them by transforming Simon Williams into Wonder Man so that he could infiltrate the Avengers' ranks.[8]

Ultimately, Zemo's plans were never successful. In his final attack against Captain America, he kidnapped the Captain's sidekick, Rick Jones, and brought him to his South American lair. Captain America rescued Jones, and when fleeing Zemo, the glare from Captain America's shield reflected into Zemo's eyes. Temporarily blinded, Zemo fired his death ray wildly, causing an avalanche that killed himself.[9]
