List

"It's over. Fury has released everything to the public." "Everything he knows about." "Herr Strucker, if they get word of our work here, if they find out we serve HYDRA..."

- List and Wolfgang von Strucker

Doctor List was a scientist and one of the prime figureheads of HYDRA. He also served as the right-hand man of Wolfgang von Strucker.

S.H.I.E.L.D.
Doctor List was a member of S.H.I.E.L.D.

HYDRA
Doctor List joined HYDRA and became the lead scientist of Wolfgang von Strucker's division. Eventually, he became von Strucker's representative at the meetings of HYDRA's leadership.

Working in Sokovia
"How fast can you get to work, Doctor List?" "Immediately, Herr Strucker."

- Wolfgang von Strucker and List

Wolfgang von Strucker had Doctor List stationed at the research facility in Sokovia during its civil protests to wait for the arrival of the Chitauri Scepter. When it arrived, List used the scepter to activate Chitauri Guns for usage. Ultimately, he was asked to learn how that energy interacted with human beings whom he had convinced would receive power equal to Iron Man or the Avengers. He told the protesters that if they consented, he would make sure that the constant revolutions would end. Among those who volunteered were the twins Wanda and Pietro Maximoff; they were particularly fascinating to List because he wanted to document how their relationship affected the possibility of their gaining power.

Civil War Aftermath
"What about the volunteers?" "The dead will be buried so deep their ghosts won't be able to find them."

- List and Wolfgang von Strucker

Two years after obtaining the Chitauri Scepter, List was still performing experiments on it. Though almost all of his human lab rats died during the experiments, the Maximoff twins managed to survive, gaining extraordinary abilities. After the destruction of Project Insight and the subsequent exposure of HYDRA's infiltration of S.H.I.E.L.D., List became paranoid over the possibility of their work being discovered. However, Strucker assured him that their work would continue.

Round Table Discussion
"Thank you, Mr. Bloom, for hosting. I regret that our biannual gathering has turned into a vigil." "Daniel Whitehall has joined our founder in the afterlife." "How unfortunate. I admired the man's commitment."

- List, Octavian Bloom, and the Baroness

Representing Wolfgang von Strucker, List went to a meeting of the leadership of HYDRA to decide who would replace Daniel Whitehall as the American commander. Included in the discussion were the Baroness, the Sheikh, the Banker and Octavian Bloom. List told the others that the person who destroyed S.H.I.E.L.D. would replace Whitehall. In the meantime, he would take a look at Whitehall's research of arcane artifacts to see if there was anything useful in it for HYDRA. That evening, List received a phone call from Bloom, who had been contacted by Sunil Bakshi, who had almost been assassinated. List assured him that he nor Baron Wolfgang von Strucker placed a kill-order on him or Sunil Bakshi, making Bloom turn against the other three members of the council and have them executed.

However, as it turned out, the whole story about the power struggle within HYDRA's ranks was concocted by S.H.I.E.L.D. to trick HYDRA into destroying their own members.

Later, List became interested in powered people. List's soldiers started hunting them and managed to capture several of them, and List used the opportunity to experiment on them.

Quantum Entanglements
"Still no quantum signature?" "No, Dr. List." "That's a waste. Take the cadaver to the lab. Compare him to the other samples. Hail HYDRA!"

- Doctor List and Paula

HYDRA successfully captured a powered being called Ethan Johnston, who had been teleported by the eyeless man they were hunting. List took control of the experiments, leading the Johnston's death after hours of surgery and torture. When List was frustrated that they had been unsuccessful in finding Quantum Entanglements in Johnston's DNA.

When Sunil Bakshi called for a meeting with List, he arrived along with a bodyguard known as Deathlok. List asked Bakshi how he had escaped after Daniel Whitehall, Octavian Bloom and the other heads of HYDRA had been killed by S.H.I.E.L.D., Bakshi revealed he had been held captive by the US Army, but lied, saying that he was rescued by Deathlok. Bakshi offered to trade Deathlok for a chance to work at Baron Wolfgang von Strucker's base in Eastern Europe. When the teleporter was located, List sent Deathlok and Bakshi to find anyone connected with him. The team was able to capture both Deathlok and Lincoln Campbell.

List took the pair to the Arctic HYDRA Research Facility where he and Sunil Bakshi discussed the upcoming experiments; when Bakshi mentioned Daniel Whitehall's motto of discovery requires experimentation, List said that he missed Whitehall. List began the experiments on the pair, removing Deathlok's eyeball and cybernetic leg. Eventually they saw S.H.I.E.L.D. was approaching on the radar and List ordered them to be shot from the sky. The S.H.I.E.L.D. Agents survived the explosion and attacked the base; List managed to escape but S.H.I.E.L.D. was able to free Deathlok and Lincoln Campbell before destroying the base.

The Avengers Attack
"Let's show them what we have accomplished. Send out the twins."

- List to Wolfgang von Strucker

Not long after List returned to the HYDRA Research Base, the base was attacked by the Avengers who were searching for the Chitauri Scepter and Baron Wolfgang von Strucker. As the Avengers managed to easily overpower their HYDRA soldiers, List told Strucker to send in the Maximoff twins, Strucker however insisted they were not ready, but List noticed that the twins had attacked the Avengers anyway. When the base's shields were destroyed, Strucker ordered his men to continue fighting before telling List he would surrender. As Strucker attempted to escape, Iron Man flew into the base and subdued the HYDRA soldiers, including List whom he shot in the side of the head.
