Baron Zemo () is the name of two <!--Do not add "fictional" as it is tautological; supervillains (and characters in general) are by definition implied to be fictionalized to some extent.-->supervillains appearing in American comic books published by Marvel Comics. Heinrich Zemo and his son Helmut Zemo have both been depicted as a major adversary of Captain America and the Avengers, as well as the leader of the Masters of Evil, a team comprising numerous villains in the Marvel Universe.
In the 2021 radio drama podcast series Marvel's Wastelanders, two original incarnations of King Zemo (voiced by James Saito) are introduced as Helmut Zemo's successors as Dictators of the Wastelands: Herman Zemo (voiced by Ki Hong Lee) and Ash Morse (voiced by Sasha Lane).
Publication history
The initial published version of Baron Zemo was created by Stan Lee and Jack Kirby and was first seen in a flashback in The Avengers #4 (March 1964). The character did not actually appear in person and was not identified as Heinrich Zemo until The Avengers #6 (July 1964) and Sgt. Fury and His Howling Commandos #8 in the same month. Zemo was retroactively added into the history of Captain America upon the hero's reintroduction to the Silver Age two issues prior. The character subsequently appears in The Avengers #7 (Aug. 1964), #9-10 (October–November 1964), Tales of Suspense #60 (December 1964), and The Avengers #15 (April 1965), in which he is killed.
Since then, Helmut Zemo has used the Baron Zemo title since Captain America #275.
Harbin Zemo, the progenitor of the Zemo line was first seen, via flashback, in the Avengers/Thunderbolts limited series. The backstory of the 11 barons before Heinrich and Helmut was later touched upon in the limited series Thunderbolts Presents: Zemo – Born Better. So far it seems that every baron is succeeded by his son. According to Wendell Volker's notes, Harbin had other children before Hademar who did not survive to adulthood; Herbert had two sons who died of illness prior to Helmuth.
Line of Barons in the Zemo family
; Marvel Universe
- Harbin Zemo – The first Baron Zemo, who was active in 1480.
- Hademar Zemo – The second Baron Zemo, son of Harbin Zemo and the greediest of the Zemos. He was killed by the guards (acting under Heller Zemo's orders) at his inauguration.
- Heller Zemo – The third Baron Zemo, son of Hademar Zemo and the most progressive of the Zemos.
- Helmuth Zemo – The fifth Baron Zemo, son of Herbert Zemo. He was assassinated by a time-displaced Helmut Zemo.
- Hobart Zemo – The tenth Baron Zemo, son of Hoffman Zemo. It was only after the war that the adhesive-using villain Paste-Pot Pete (later known as the Trapster) 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 face and permanently bound his mask to his face. 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, abandoning his long-suffering wife and toddler son, toward whom he had become physically and emotionally 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.
Heinrich then formed the original Masters of Evil to serve as an evil version of the Avengers; the other founding members included the villainous 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 the remover made by Paste-Pot Pete. Zemo used his sceptre's hypno-ray on the Teen Brigade, placing them under his control.
In his final battle with Captain America, 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.
The 13th Baron Zemo, Helmut J. Zemo, the son of Heinrich Zemo, then followed in his father's footsteps, battling Captain America many times to avenge the killing of his father. Helmut was then responsible for bringing back the Masters of Evil and then forming the Thunderbolts.
