3 appearances

Purpose

To trigger an explosive device as a last-resort defense against the Dalek assault, providing a tactical distraction or disruption to their invasion.

Significance

Represents the Doctor's desperate gamble in a losing battle, highlighting his vulnerability and the inadequacy of direct confrontation against the Daleks. The detonator's failure forces an immediate tactical retreat and sets up the subsequent reliance on Spiridon's geothermal forces, underscoring the episode's theme of shifting power dynamics.

Before: A hastily constructed device with frayed connectors, insulating tape, and a single activation button glowing faintly in the Doctor's palm.

After: Rendered unusable by the failed attempt, its power too weak to alter the Dalek advance.
