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
Wolfgang Von Strucker had Doctor List stationed at theresearch facility in Sokovia during its civil protests to wait for the arrival of the 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.
