Used by Ice Warrior physician Izlyr to analyze Jo Grant's claims about the Doctor's alleged attempt on Arcturus' life
3 appearances

Purpose

To induce temporary metabolic coma for non-lethal incapacitation or medical restraint in Ice Warrior protocols, likely repurposed in this scene as an instrument of political pressure rather than surgical sabotage

Significance

Serves as a flashpoint for ideological confrontation between Jo’s guilt-by-association tactics and Izlyr’s insistence on peaceful reform, exposing the fragility of the temporary alliance and forcing both parties to confront their underlying mistrust of one another’s motives

Izlyr accuses Jo of treachery

Jo presents the Metabolic Sensor Unit as purported evidence of Ice Warrior assassination intent, only for Izlyr to immediately clarify its function as non-lethal medical equipment designed to induce a coma without fatal consequences. The object’s technological design thus shifts from incriminating weapon to contested tool, undermining Jo’s accusation.

Before: Hidden in the Ice Warrior chamber, part of Izlyr’s medical or administrative kit

Izlyr reveals Ice Warriors' peaceful shift

The Metabolic Sensor Unit is central to the confrontation, as Izlyr identifies it as harmless sensor equipment rather than a weapon. Held aloft as physical evidence, its technical explanation invalidates Jo's sabotage accusations, defusing the tension. The object's myth of lethality is dismantled, revealing its true non-lethal function.

Before: Presumed to be a lethally intended sabotage device, seized from the room

S9E6 · The Curse of Peladon Part 2
Jo challenges factions on Peladon

The Metabolic Sensor Unit becomes the focal point of contention as Jo holds it aloft to accuse the Ice Warriors. Izlyr’s explanation that it only induces metabolic coma rather than fatal harm reframes its purpose, transforming it from damning evidence into a non-lethal instrument in political maneuvering.

Before: Hidden in the Ice Warrior’s room, presumably planted or mistakenly retrieved
After: Held by Jo as physical proof, its non-lethal function now central to the debate
