Mustakozene Eighty Reagent

A colorless chemical agent stored in Borad’s laboratory, Mustakozene Eighty appears as a clear liquid in sealed glass vials. The Doctor handles it cautiously after sampling its role in Borad’s experimental Morlox amalgamation process. When introduced to Morlox gas, it triggers violent tissue transformation in both the creature and Borad himself, creating grotesque biological hybrids. Its potency demands careful storage—vials bear handwritten hazard warnings and are kept locked within Borad’s experimental array.

Doctor faces Borad's true form

The Doctor directly references Mustakozene Eighty after recognizing the gas canister’s chemical signature, revealing its role in Borad’s grotesque transformation and Morlox hybridization experiments. This acknowledgment shifts the object from mere reagent to the engine of Borad’s power and personal vengeance, binding science to tyranny.

Before: Stored securely within Borad’s experimental array in the vault, likely on display or under lock.
After: Identified and linked to Borad’s rituals of transformation; its danger becomes part of the ideological battleground between Doctor and tyrant.

S22E11 · Timelash Part 2
Doctor and Borad clash in vault showdown

Mustakozene Eighty is the chemical agent Borad claims transforms Morlox and himself, but the Doctor exposes its role as a catalyst for uncontrolled, grotesque tissue amalgamation. Borad intends to use it on Peri to create a mutant mate, though the Doctor dismantles this plan as pseudoscience.

Before: Contained in a vial within Borad’s laboratory; its hazardous nature was evident from warning labels.
After: No direct interaction; remains implied as a key plot device even after Borad’s defeat.

S22E11 · Timelash Part 2
Borad exposes his mutant breeding plan

The vial of Mustakozene Eighty is referenced as the chemical reagent that excited the Morlox and drove Borad’s mutation experiment. Though not physically present, it is central to the Doctor’s interrogation, Borad’s delusions, and the creature’s predatory behavior in the cavern.

Before: Stored in Borad’s laboratory, part of his experimental array
After: Implied used in the planned Morlox attack on Peri to trigger forced mutation
