Boom Spheres were powerful weapons created by Michael Holt that were capable of killing the New Gods. Reverse engineered from the Motherbox and adapted into his own spherical design, Holt made the weapon unstable on purpose. Once stabilized, the Spheres were incredibly powerful to the user. Using one sphere, a person could teleport something into the next one and when placed next to another sphere, it could disintegrate matter. When Terry Sloan attempted to stablize the spheres, Holt neutralized them instead.
