Role in the series[]
Baron Heinrich Zemo was seen in a flashback when he was fighting Captain America and Bucky Barnes. It is mentioned that he was imprisoned upon his defeat.
Baron Helmut Zemo was seen when he planned to finish his father's work into making an attempt at the super-soldier serum. In order to access it, he uses old-fashioned hypnosis to have Captain America re-enact his and Bucky's fight with his father Heinrich in order to find his lab. Using his attempt at a super-soldier serum, Helmut used it on two Hydra operatives, turning them into large brutes. He ended up injecting himself with one of his father's super-soldier serums, effectively euthanizing himself as well gaining as superhuman strength and speed. After this occurred, Helmut engaged Iron Man and Black Widow in battle. After the illusion of Bucky snapped him out of his hypnosis, Captain America joined the fight against Helmut. When the cliff the fight occurred on gave way, Helmut refused Captain America's offer to save him and fell into the ocean to retrieve the last of his father's super-soldier serum. Iron Man's computers could not detect Helmut under the surface of the ocean.
Zemo later resurfaces as the superhero Citizen V, helping the Avengers defeat Growing Man. Originally, his plan was teaming up with the Masters of Evil and disguising them as a new superhero team called the Thunderbolts. However, when their secret was exposed, the Avengers and Masters were left to die in a collapsing warehouse while Zemo as Citizen V gained public sympathy from their deaths. However, the Avengers and the Thunderbolts, now genuinely reformed, exposed his true identity to the city, foiling his plan. Initiating a backup plan, Zemo unleashed a supercharged Ulysses Klaw against them, while he escaped.
After obtaining leftover time travel technology from Kang the Conqueror, Zemo constructed a time portal to make contact his father, Heinrich Zemo, the original Baron Zemo. He eventually was able to bring his father from the 40s during World War II to the present day, just as Captain America, Falcon and Black Widow arrived. Heinrich resolves to strand the three Avengers in his own time period, forcing them into the portal. During the fight between the Avengers and the Zemos, Heinrich started to see Helmut as a disappointment enough to use the time machine to bring forward a Zemo from the year 2099. After Helmut got trapped under some debris, his own father declined to help him. After being freed from the debris from Captain America, Helmut worked with Captain America to send Heinrich back to 1943 which also erases Zemo 2099's existence. As Helmut had cooperated with Captain America, he won't be sent to the Vault. Baron Zemo next appears in Avengers: Secret Wars. Zemo has a confrontation with Black Panther and Ant-Man while obtaining a Wakandan relic hidden away by T'Chaka and Heinrich. Despite being empowered by the hidden relic (to the point of insanity), he is defeated by the two members of the New Avengers.
