During the "Secret Empire" storyline, Arnim Zola was present with Hydra's High Council as Hydra takes over the United States. It was later revealed that Arnim Zola was behind the A.I. Virus that is controlling Vision to be a part of Hydra's Avengers. As the Hydra Helicarriers attack the hideout of the Underground, Arnim Zola mentions that their attacks won't bring down their defenses. Captain America states that they will unleash their secret weapon. Arnim Zola tells Captain America that their subject in the vault is awake but disoriented and that the procedure they did on him is temporary as his condition will degrade quickly. After brushing off Arnim Zola's concerns, Captain America states that they only need their subject for a short time to bring the Underground down. When the vault opens, it is revealed that the person they are talking about that is a somehow-revived Bruce Banner.
