## Fictional character biography

Heinrich Zemo, the 12th Baron Zemo, was one of the top scientists in the Nazi Party. Zemo fought both Captain America and his allies the Howling Commandos during World War II. A brilliant and sadistic scientific genius, Zemo created many weapons of mass destruction for Hitler's army, including a large-scale death ray cannon, a disintegration pistol that was a miniaturized version of his death ray, and primitive androids of considerable strength and durability. Heinrich's intelligence was only matched by his sadism, as he routinely tested his deadly weapons on innocent people, both prisoner and civilian, inside the Third Reich. This ultimately came to a head during an early encounter with the Howling Commandos, when Zemo decided to test an experimental death ray cannon on a nearby German town. The death ray killed hundreds of innocent German civilians as a result, making Zemo a mass murderer. Though he arrogantly believed that he could frame the Allied Forces for his act of mass murder, Nick Fury and the Howling Commandos exposed Zemo's role in the town's destruction, resulting in Zemo becoming a reviled figure throughout Europe, even amongst his fellow Germans.
In an attempt to regain a level of anonymity, Zemo began wearing a reddish-pink hood over his face as he continued to build weapons for the Nazis. His activities ultimately drew the attention of Captain America, resulting in a confrontation just as Heinrich was ready to unveil his newest scientific breakthrough: Adhesive X, an extremely strong adhesive that could not be dissolved or removed by any known process at the time; it was only after the war that Paste-Pot Pete found a way to neutralize it.
To ensure that the Nazis could not use Adhesive X against Allied troops, Captain America confronted Zemo in an attempt to destroy the limited supply. Captain America threw his shield at the vat to release the adhesive onto the ground. Zemo, however, was standing right next to the vat containing the chemical, which poured over his hooded face. The adhesive quickly seeped inside and permanently attached the hood to Zemo's flesh, preventing him from ever removing it.
Though Zemo could still see through the eye holes of the hood, as well as hear, breathe, and speak through the thin fabric of the cloth that made up the hood, Zemo could no longer eat normally and had to be fed intravenously. Heinrich quickly recovered, but having his hood permanently attached to his face drove him insane. Adopting a new costume, Zemo went from becoming a normal, if not infamous, Nazi scientist to become an active field agent for the Third Reich, leading German troops into combat and espionage missions.
At some point, Zemo battled and killed Citizen V (John Watkins), the leader of the V-Battalion freedom fighters.
When it became apparent that the Nazis would lose the war, Red Skull sent Zemo to London to steal an experimental airplane. At this point the plane would do them no good, but Red Skull made sure that this knowledge was leaked to Captain America and young sidekick Bucky so as to ensure that Zemo would be caught, thus ridding him of his rival once and for all. Captain America would not learn of Zemo's scheme for several weeks, by which time he would defeat Red Skull for the final time during World War II, burying Red Skull alive in a state of suspended animation. By the time that Captain America learned of Zemo's plot, it was too late and both Captain America and Bucky were taken prisoner by Zemo. Zemo tied the two heroes to the experimental plane, which was now booby-trapped to explode, and launched them to their deaths. Captain America fell from the plane as it exploded, and Bucky was apparently killed. Captain America landed in the Arctic Ocean and was frozen in ice for decades before being recovered by the Avengers.
Believing that he had killed his rival at long last, Zemo fled to South America as Hitler and the Nazis fell and World War II ended. After the mask was permanently bonded to his face, Zemo abandoned his long-suffering wife and his son Helmut, toward whom he had become emotionally and physically abusive. With an army of mercenaries loyal to him, Zemo enslaved a tribe of natives and lived as a king as he tried desperately to find a solvent that would remove his mask. After decades passed, Captain America was revived by the Avengers. This causes Zemo to renew his rivalry with the Captain. Among his attempts included sending agents to take the place of participants of a hand-to-hand combat demonstration with Captain America to capture him. As Captain America learned that Zemo was behind this attack, he sent a taunting message on Zemo's minions' communicator to provoke the villain into becoming more carelessly aggressive against him and thus provide an opportunity for the superhero to deal with the villain directly.
To that end, Heinrich formed the original Masters of Evil to serve as a villainous counterpart to the Avengers; the other founding members included the Black Knight, the Melter, and the Radioactive Man who were gathered by his pilot. He tried to have Adhesive X spread over New York, but the Teen Brigade seized Zemo's pilot, preventing him from speaking, then tied him up to stop him causing trouble. They switched the adhesive with remover made by Paste-Pot Pete. Zemo used his sceptre's hypno-ray on the Teen Brigade, placing them under his control. He then battled Captain America using combat skills he had gained, but Captain America began to beat him. The pilot freed himself from his bonds and shot at Captain America from behind. Captain America heard the sound and dodged the bullet, though his skull was grazed. Giant-Man was able to stop the pilot from killing Captain America, thus capturing him. Zemo was tricked into opening a container of tear gas while in his helicopter during his escape back to South America. He is later joined by the Enchantress and the Executioner, who Odin exiled to Earth. The Enchantress hypnotized Thor into attacking the Avengers, while the Executioner had disguised himself as a former ally of Zemo and lured Captain America to South America to fight Zemo. Iron Man broke Thor out of this trance and the Masters of Evil were sent to another dimension by Thor. Zemo later turned Simon Williams into the superstrong Wonder Man with his ionic ray, and said that Wonder Man would die within a week unless given an antidote which Zemo possessed. Wonder Man was able to capture the Wasp and led the group into a trap where they were defeated. Wonder Man, however, sacrificed himself to save the Avengers.
In his final battle with Captain America, Zemo lured the Captain to his jungle fortress by kidnapping Rick Jones using an attractor ray. His Masters of Evil were broken out of prison and attacked the Avengers, forcing Captain America to go on alone. Zemo raised a glass cage containing Rick out of the ground as Captain America fired at his men, hoping Captain America would kill Rick, but the gunfire only broke open the cage. Zemo tried attacking with his men, but Captain America was able to use a rockslide caused by his shield to block them. In the ensuing battle, Captain America used his shield to deflect the sun's rays and cause Zemo to shoot blindly. His ray gun's shot hit a rock, starting an avalanche that killed him, and Captain America felt that Bucky's death had finally been avenged.
Zemo has largely remained dead since. However, he has appeared as a spirit and was temporarily resurrected as a member of the Legion of the Unliving.
