During the Guns of the Patriots Incident in 2014, the Beauty and the Beast Unit member Screaming Mantis used two dolls to manipulate a soldier's nanomachines. One, modeled after the FOXHOUND psychic Psycho Mantis, would manipulate living soldiers. The other, modeled after the Cobra Unit medium The Sorrow, would manipulate dead soldiers, although Otacon speculated that the latter's method was similar to using electric currents to "reanimate" a dead frog. The creators of these dolls were unknown, as were their exact age. They released whisping orbs comparable to ghosts to allow for the control mechanism to activate, and also had a line they uttered matching that of their namesake.
