History: (Captain America: The Medusa Effect#1 (fb)) - Heinrich Zemo was born in 1900, and served in the Germany army during World War I. He felt betrayed when Berlin surrendered to the Allies, and was an early member of Hitler's National Socialist party afterwards, becoming a member of the Nazi Party's Brown Shirts.
(Captain America I#168 (fb)) - Heinrich married a woman named Hilda, and she bore him a son, Helmut. Heinrich loved his family, and became a leading scientist in the Third Reich.
(Captain America: The Medusa Effect#1 (fb)) - Zemo traveled to America in 1933 and met Dr. Nikola Tesla, learning from him of his invention "Teleforce," a powerful laser weapon. By 1939, Hitler had promoted Zemo to the rank of colonel.
(Thunderbolts Presents: Zemo - Born Better#3 (BTS), 4) - Hitler, his aide Johann Shmidt and scientist Abraham Erskine witnessed a test of Zemo's death-ray, used on a live human to see how quickly it would kill him. Erskine was outraged by the barbaric nature of the tests, but Hitler ignored him. After the demonstration, Heinrich found a stranger in the lab, unaware that it was his own son Helmut, time traveling his way through the history of the Zemo family. Heinrich began to launch into a speech of German superiority, but Helmut ultimately became enraged and attacked him, declaring himself to be superior to Heinrich. Heinrich had his guards attack Helmut, but Helmut was teleported back to the present before they could kill him.
(Sgt. Fury and his Howling Commandos#8) - Soon after completing his first version of the death-ray, Zemo's castle in Germany was invaded by the Howling Commandos, come to kidnap him. Zemo attempted to kill them with his castle's death-traps, but they avoided them, and when he confronted them with his death-ray, "Reb" Ralston snatched it from his hands with his lariat. Zemo fled his castle and destroyed it as he departed by self-destructing the death-ray, hoping to slay the Howlers. However, the Howlers survived, and discovered that the death-ray's energies had slaughtered a nearby town. They had leaflets distributed through Germany revealing what Zemo had done, and he was disgraced before his own nation.
(Avengers I#6 (fb)) - Because of the leaflets, Zemo became "the most hated man in Europe" (surely Hitler still held that dishonor?), and took to wearing a mask until his face was forgotten. As Zemo labored over Adhesive X, a powerful glue, he was confronted by Captain America. As they fought, the Captain's shield struck a container of Adhesive X, and the glue spilled over Zemo's face, welding the mask to his skin.
(Captain America I#168 (fb)) - With his mask fused to his head, Zemo began to lash out against his own family, striking Helmut. He finally left Hilda and Helmut to focus on his plans for the Third Reich, and for the defeat of Captain America.
(Captain America I#606 (fb) - BTS) - At some point Heinrich did something for Jurgen Hauptmann, who was from that moment on indebted to him.
(Captain America: The Medusa Effect#1) - In 1943, Using Tesla's "teleforce" theories, Zemo designed a new death-ray, called "the Medusa Cannon." Zemo sent Master Man to America to kill Tesla and destroy his notes, while he prepared the Medusa Cannon to shoot down Allied bombers as they flew over Berlin. Zemo's own wife Hilda turned against him, and brought Captain America to his laboratory in the hopes of stopping him. However, Master Man defeated Captain America. Bucky broke into the laboratory with the help of Helmut, but Helmut turned Bucky over to his father. Heinrich promised Helmut that he would be the first to fire the Medusa Cannon for his work. Zemo strapped Bucky to the Medusa Cannon, but Captain America had set himself free, and overpowered Master Man. Helmut foolishly activated the cannon when it wasn't aimed at the sky, and it wound up destroying Zemo's laboratory. Captain America and Bucky took Helmut to safety, but Hilda was killed by debris.
(Captain America/Citizen V 1998 Annual (fb)) - Zemo, aided by the She-Wolf, attempted to launch Particle X, a weapon that would nullify all radio and radar operations in Britain, granting the Nazis a major advantage. However, She-Wolf betrayed Zemo to Citizen V, Captain America and Bucky, who stormed Castle Zemo and destroyed Particle X before it could be launched.
(Thunderbolts: Distant Rumblings#-1 (fb)) - Later in 1943, Zemo again encountered the heroic Citizen V in Poznan, Poland, where he had led his V-Battalion against Nazi forces. Heinrich shot Citizen V, then strangled him to death.
(Official Handbook of the Marvel Universe Deluxe Edition - Baron Zemo (fb) - BTS) - Zemo assisted Arnim Zola in creating a pair of androids which could grow in size.
(Tales of Suspense I#80 (fb) - BTS) - Zemo was ordered to steal an experimental drone plane by the Red Skull from a facility in England.
(Spider-Man: Fear Itself) - On April 30th, 1945, Hitler met with Heinrich Zemo, informing him that he planned to commit suicide that night. As a reward for his faithful service, Hitler told him, "like your Führer, Zemo, you will become...a god..."
(Avengers I#56) <May 2, 1945> - Zemo used a pair of massive androids to aid him in his mission, and had them defeat Captain America and Bucky when they intervened. Zemo strapped them to the drone plane, intending to send them to Berlin as prisoners. However, time-traveling members of the Avengers (including Goliath, Hawkeye, the Black Panther and Captain America) appeared, and attempted to alter history. Although they vanished before they could change time, Cap managed to set his and Bucky's past selves free.
(Avengers I#4 (fb)/Avengers I#56) - Zemo launched the drone plane as Captain America and Bucky chased after it. When Bucky grabbed on to the plane, he realized it was booby-trapped, and Zemo destroyed it from the military base. Zemo believed that Captain America had been slain in the explosion as well, but he was actually cast into the ocean.
(Captain America I#257 (fb) - BTS) - One of Zemo's assistants during the war went on to lead Matrix Eight, a band of other Nazi fugitives who sold weapons.
(Avengers I#6 (fb) - BTS) - Heinrich moved his base of operations to a temple in the Amazon jungle, and conquered some of the native people, making them his slaves. He also brought his mercenary army along, including amongst their ranks Erik Josten.
(Thunderbolts Presents: Zemo - Born Better#4 (fb)) - Heinrich showed Helmut the construction of his temple, and declared that one day in the future they would strike back against their "Zionist" enemies.
(Thunderbolts: Distant Rumblings#-1) - Heinrich was reunited with Helmut, now a grown man, and had him subject himself to his Compound X to increase his life span. When Heinrich's slaves rose up in revolt, Heinrich placed Helmut into the care of Erik Josten, and led his mercenaries in assaulting the slaves. When the slaves were defeated, he had the leaders brought forth, and asked Helmut what should be done with them. Helmut suggested flogging them, but Heinrich was adamant that in order to bring down a resistance, you must destroy hope, and shot the leaders dead.
(Avengers I#6) - Zemo had his pilot Franz Gruber bring him news from America, but was disappointed that the latest science journals held no answers to the removal of his mask. Then he noticed an article revealing that Captain America was alive, and had joined the Avengers. Zemo decided to prepare an attack on the Avengers.
(Untold Tales of Spider-Man#13 - BTS) - As Zemo began to gather allies to confront the Avengers with, the Black Knight made a bold bid for "captaincy" in his group, kidnapping the princess of Ksavia. As the Black Knight contacted Zemo to boast of his success, Spider-Man invaded his hideout, and Zemo told the Black Knight to deal with him, and that he would be contacted later. The Black Knight was finally defeated by Spider-Man and the Human Torch, but someone -- possibly an agent of Zemo's -- collapsed a building on the two heroes so that the Black Knight could escape.
(Avengers I#6/Avengers: Earth's Mightiest Heroes#3) - Zemo recruited the Radioactive Man, Melter and Black Knight into his Masters of Evil, and equipped them with Adhesive X, spraying it throughout New York in order to draw out the Avengers. They succeeded in bringing them out, and managed to affix Captain America and Giant-Man to the pavement of a street, forcing the Avengers to find an antidote for the adhesive.
(Avengers I#6) - After the Avengers had found an antidote (thanks to Paste-Pot Pete), Rick Jones filled the Masters' containers of Adhesive X with the antidote so that they would set free all the people they had trapped earlier while on another run. The Avengers defeated the Masters, and Captain America himself faced Zemo in combat, forcing him to flee. Zemo departed with what he thought was a sample of the antidote, but it was actually a container of tear gas, and he crashed his ship while fleeing.
(Avengers I#7 (fb) - BTS) - Zemo slipped through the Avengers' fingers, and returned to South America.
(Avengers I#7) - Zemo had his slaves bring him treasure in order to cheer him up, and was visited by the Enchantress and Executioner, who joined the Masters of Evil in order to gain revenge on Thor. The Executioner lured Captain America to Zemo's temple, and Zemo sent his slaves to fight him, but the Captain overcame all of Zemo's defenses. Zemo fled to America for his allies, but the Captain followed. They fought again, but the Executioner knocked out Captain America from behind. Zemo's airship was then cast into a space-warp by Thor.
(Avengers I#9) - After returning to Earth thanks to the Enchantress, Zemo had his allies bring him Simon Williams, whom he transformed into Wonder Man, using his ion-ray machine. Zemo kept Wonder Man under his control because the process which powered him would also kill him without an antidote only he could provide. They then launched a false attack on the Avengers so that Wonder Man could come and save them, and the Enchantress helped trick the Avengers with her magic so that they would believe Wonder Man's story about wanting to become an Avenger. Wonder Man then led the Avengers into an ambush in the Amazon, but turned against Zemo when he learned they would kill the Avengers. Faced by the revived Avengers, Zemo fled with the Masters of Evil as Wonder Man passed away, deprived of Zemo's antidote.
(Avengers I#10) - Zemo was approached by Immortus, who offered to assist the Masters of Evil against the Avengers. He kidnapped Rick Jones in order to bring Captain America into the past, but the Captain returned in time to aid the Avengers against the Masters. The Enchantress sent herself, Zemo and the Executioner back in time, and they prevented Immortus from contacting them the second time over.
(Tales of Suspense I#60/2) - Zemo had some of his men train to battle Captain America by dressing one of them in Captain America's uniform. He sent his assassins to America to deal with the real Captain America and attacked him at a charity exhibition, using Formula X, only to be defeated by him and Rick Jones. Captain America then sent out a broadcast which Zemo received in which he called Zemo a coward, and vowed to face him soon.
(Avengers I#15/Avengers: Earth's Mightiest Heroes#5-6) - Zemo kidnapped Rick Jones with his airship's tractor beam, and had the Enchantress and Executioner release the Black Knight and Melter to face the Avengers. Captain America pursued Zemo to the Amazon and freed Rick, then faced Zemo in combat again. Zemo fired a shot at the Captain which was reflected off his shield, blinding him. Zemo fired a wild shot which started an avalanche.
(Avengers I#131) - Just moments before his death, Zemo was snatched away by Kang and made a member of his Legion of the Unliving, sending them to face the Avengers in a maze within Immortus' Limbo.
(Avengers I#132) - Zemo was disappointed that Captain America was not amongst the ranks of the Avengers he faced, but participated in skirmishes with the Vision, Hawkeye and Iron Man.
(Giant-Size Avengers#3) - Kang's control over Zemo began to fade as his own personality asserted itself, and he began to question Kang's authority to lead him. Kang reminded him that only he possessed the power to keep Zemo alive. Zemo then went off and fought Hawkeye in a chamber where Immortus and Rama-Tut were being held prisoner by Kang. After defeating Hawkeye, Zemo complained about the Adhesive X that fastened his mask to his face. Immortus offered to let Zemo go back in time and prevent his mask from being stuck. This allowed Hawkeye a chance to break Immortus out, and Immortus transformed Zemo into a blob of protoplasm. After Kang had been driven off, Immortus returned Zemo to normal and returned him to the moment of his death.
(Avengers I#15/Avengers: Earth's Mightiest Heroes#6) - Zemo was crushed to death by the avalanche he had started.

(Captain America I#362) - Hoping to revive his father with the Bloodstone, Helmut carried his father with him to Hong Kong in search of the Bloodstone fragments. However, when the fragments assembled themselves nearby Zemo's body, the spirit of the Hellfire Helix took possession of his form and attacked Helmut and Captain America. Zemo's body was destroyed when the mercenary Crossbones fired a crossbow bolt into the Bloodstone, shattering it.
(Incredible Hercules#129) - Residing in Hades Heinrich served in Pluto's Jury for Zeus' trial.
(Incredible Hercules#130) - Hercules attacked the Jury and some of Nessus' blood spilt in Zemo's face. Due to Nessus' blood being mixed with the Hydra's poison Zemo had to endure agonizing pain.
Comments: Created by Stan Lee, Jack Kirby and George Roussos.
Zemo was first referred to by the title of Baron in Daredevil Annual#1, after his death. He was referred to as "Dr. Zemo" in most of his early appearances.
In Spider-Man: Fear Itself, the Baroness claimed to be Heinrich Zemo, his mind transferred into the body of a woman by Arnim Zola. However, the Baroness herself later denied this in Captain America I#432.
Kenneth Sturdy was said in Avengers I#164 to have been present at the creation of Wonder Man, which is how he was able to replicate the process for Count Nefaria, but Zemo had no assistant visible in Avengers I#9.
As Helmut Zemo is the 13th Baron Zemo, this would make Heinrich Zemo the 12th.
A perfect example of why not to call him Baron Zemo I, ya HAMMERHEADS!!!--Snood
Fantastic Four Annual#11 depicted an alternate reality wherein Zemo obtained a canister of Vibranium that had accidentally been transported back in time and used it to develop weapons which would have won the war for the Nazis, but the Invaders and Fantastic Four of Earth-616 defeated him.
Thanks to Ronald Byrd for adding a missed flashback from Deadpool III#28.
A complete list of all 13 Baron Zemos was presented in Thunderbolts Presents: Zemo - Born Better#4, including the undepicted Hoffman Zemo.
Unless Timely Comics gave someone else credit for creating the Nazi Death Ray (Laser), the Death Ray used by the Black Ace (the Flying Flame) and the Disintegrator Gun that Asbestos Lady's brother "Killer" Murdock found could've been created by Baron Zemo.
by Prime Eternal
Heinrich Zemo should not be confused with:
Zemo once trained an army of assassins to defeat Captain America for him, and they faced him at a charity exhibition, fooling some of the onlookers into believing it was all a show. However, they failed in their mission, finally being defeated by Captain America and Rick Jones.
Each assassin was a specialist in unarmed combat, and carried weapons such as an iron fist glove, a powerful knock-out drug called Formula X, knock-out gas guns, clubs, and a miniature missile launcher that could be concealed within a belt buckle.
