Biomechanical Dalek Chair & Control Helmet

A single biomechanical chair system consisting of a segmented metallic frame with armored ridges, featuring a raised helmet interface that serves as the neural control mechanism. The combined system rested against Ratcliffe's yard wall, controlled by Black Dalek to probe operational status. When the Girl interfaces with it by sealing herself inside via the helmet, she becomes the vulnerable conduit for the Daleks' battle computer. The Doctor later destroys the time controller embedded in the system to neutralize its control over her mind. The helmet serves as both the interface for organic controllers and the key to manipulating temporal hardware like the Hand of Omega.
