A.I.M.'s origins began late in World War II with Baron Wolfgang von Strucker's creation of his subversive organization HYDRA. Under the code name of THEM, he created two HYDRA branches called Advanced Idea Mechanics and the Secret Empire. A.I.M.'s purpose was to develop advanced weaponry for HYDRA. They were close to developing and attaining nuclear weapons when HYDRA Island was invaded by American and Japanese troops. Although HYDRA suffered a major setback, it survived and grew in secret over the following decades.
