- "Leviathan is coming."
- ―Leet Brannis
Leet Brannis was a former Leviathan operative tasked with obtaining some of Howard Stark's weapons. He double-crossed the organization to gain personal profit. However, he was soon found by his former ally, Sasha Demidov, and killed while assisting Peggy Carter in defeating Leviathan.
Leet Brannis served as a soldier in the Soviet 478th Rifle Division during World War II. Brannis was declared dead in 1944 when his entire battalion was killed on the battlefields of Germany. He, however, survived the war and became a member of Leviathan, getting his voice-box removed because of the adverse effects that Midnight Oil had on his larynx.
Robbing Howard Stark
Leviathan tasked Brannis with robbing Howard Stark's secret technology. To do so, he chose a night of a major thunderstorm as New York City used its sewers to run off storm water into the Atlantic Ocean in 1946. Brannis used this knowledge to have a raft carry Stark's valuables from a hole cut beneath his mansion out to sea where The Heartbreak boat was posted. He hired Jerome Zandow to guard the cargo as he found buyers.
- "I'm an independent businessman, just trying to make his mark."
"By murdering people?!"
"I don't murder people; I just sell to people who do."
- ―Leet Brannis and Peggy Carter
Brannis betrayed his employers and became an "independent businessman", trying to make money selling Howard Stark's inventions on the black market. Brannis met Spider Raymond in his club, La Martinique, who bought a formula for one of Stark's weapons, Nitramene. Raymond seemed a bit uncomfortable that Brannis did not say a single word, but the deal went on without problems. Brannis took his money from Raymond and left the office.
Later on, Brannis met with Miles Van Ert at the Roxxon Refinery where they continued to produce more weapons with Stark's Nitramene formula. They were interrupted when Peggy Carter attempted to arrest the pair, knocking out Van Ert. Brannis took one of the Nitramene bombs and tried to escape, but Carter cornered him and held him at gunpoint. It then became evident that he couldn't speak on his own. He had to use a Voice Synthesizer pointed to his throat to speak.
Brannis revealed that the milk truck he was standing by was filled with dozens of Nitramene bombs and explained to Carter that he was not a killer, but merely someone who sells weapons to those who kill. Before throwing a bomb on the ground in front of Carter, he warned her that Leviathan was coming in the near future, but did not explain what that meant. He gave Carter thirty seconds to leave before he escaped with a Daisy Clover milk truck filled with Nitramene bombs as the refinery exploded then imploded into a single mass.
Capture and Death
The man in the Green Suit started a search for Brannis and began killing fences and illegal traders after getting information from them. Eventually, he found the Cedar Grove, New Jersey address of Sheldon McFee and decided to look there for him. However, Brannis was intercepted by Peggy Carter. As she fought McFee, Brannis was trying to start the milk truck filled with the Nitramene bombs, but Edwin Jarvis had disabled it. Brannis asked Carter for protection; she wanted information about Leviathan. As the trio were taking the truck to Manhattan, the man in the Green Suit leapt atop the truck.
During the fight, Brannis was shot in the shoulder. Carter, on top of the truck struggling with Green Suit, instructed him to drive the truck to a body of water she saw. As the trio jumped out of truck as it went over the edge, Brannis broke the fall of Jarvis with his body. As Brannis was dying, he drew a picture in the dirt for Carter pertaining to the location of Howard Stark's items. Carter and Jarvis fled when they heard sirens approaching. A few moments later, Agents Roger Dooley and Jack Thompson found Brannis' body. They also found evidence that a woman was involved with his death.
Dooley and Thompson discovered that Brannis was a member of the Soviet Armed Forces and that he was listed as deceased after the Battle of Finow, though, in reality, he had just died. This information intrigued Dooley to the point that he went to Nuremberg Prison to speak to Ernst Mueller to try to learn what really happened at Finow.
