Having lost Gene, Zero joined with Revolver Ocelot, Sigint, Para-Medic, EVA, and Big Boss to form the Patriots, using the Philosophers' Legacy as a source of funding and Big Boss's vision of unifying the world by controlling information. In 1972, they launched the Les Enfants Terribles Project, a plan to replicate the legendary soldier Big Boss. The project succeeded in producing three clones of Big Boss, but Big Boss himself condemned the project and parted ways with Zero. Having lost his charismatic icon, Zero went into hiding and began to rely on an AI to control the Patriots. By the 21st century, Zero had entrusted management of the Patriots' funds to the neuro-AI J.D. (John Doe).
