Cybermen seize moonbase control room

The Cybermen violently reassert dominance over the moonbase by storming the Control Room with human captives—Ralph, Evans, and Jules—who have already been partially converted into Cybermen. Hobson and Benoit, the remaining human authorities, are forced to surrender their positions as the Cybermen demand control of the Gravitron power unit. Benoit protests the Cybermen’s plan to send the converted men into the Gravitron’s lethal sonic fields without protective helmets, revealing their willingness to sacrifice human lives for their mission. The Doctor, observing quietly, subtly manipulates the R/T unit, hinting at his strategic planning. The Cybermen’s cold indifference to human suffering underscores their inhumanity and the escalating existential threat to Earth, marking the beginning of their hostile takeover of the moonbase’s critical systems.
