Strucker attempted to complete Uranverein, a nuclear weapons project, before the United States, sending Hydra agents to obtain the materials. Learning of this plot, the Invaders ultimately scuttled the Dragon, again delaying Strucker's plans, and during the clash Strucker lost the books he had brought from the future. It is also likely that because of this scheme that Strucker inadvertently caused a bootstrap paradox that lead to the establishment of the United States' Manhattan Project which builds the atomic bombs and the eventual nuclear proliferation in the first place. In 1944, Strucker encountered the Gnobians, a benevolent race of empathic extraterrestrials who had crashed near Gruenstadt. Realizing what their technology could do for Hydra, Strucker befriended the naïve creatures and killed the population of Gruenstadt to cover his tracks. The Howlers arrived, too late to prevent the tragedy, but fatally wounded Strucker. The Gnobians healed Strucker with their powers, but they went insane from absorbing some of his hate-filled psyche in the process. Strucker fled their crashed ship, taking discs of their information to his scientists. As Germany fell in 1945, Strucker had the Nazis' two greatest superhumans Master Man and Warrior Woman placed into suspended animation in opposite sides of Berlin to await later revival. Strucker also gave the Red Skull the gas used to preserve them, and it also preserved the Skull when he was buried alive in his bunker during a battle with Captain America. Avoiding prosecution for war crimes, Baron Strucker had his scientists provide him with age-retarding serum so he could personally oversee Hydra's progress for decades to come. He and the Baroness Adelicia Von Krupp once captured the CIA's Agent Ten, who proved to be Strucker's old enemy Logan, but Logan was rescued by CIA agents Richard and Mary Parker. Needing more finances for Hydra, Strucker abducted Gabrielle Haller, who had a map leading to a fortune in lost Nazi gold hidden within her mind, but Haller was defended by her friends, the mutants Charles Xavier and Erik Magnus, and Magnus took the gold for his own purposes. Strucker married more than once in the years that followed resulting in a son named Werner, who resisted his father's influence, and twins Andrea and Andreas, who were genetically altered by Hydra scientists and so, developed super powers later in life. Strucker rebuilt Hydra Island, but concealed his role in the organization by using a front
