Animal Organism Preservation Samples for Cyber Plague Carriers

Biological samples preserved for use as infection carriers in Cybermen's genocidal plot against the Vogan golden core
2 appearances

Purpose

To serve as biological vectors carrying engineered Cyber Plague payloads intended to bypass gold's corrosive effect on Cybermen physiology when deployed as bomb carriers against Vogan targets

Significance

The preserved organisms represent the Cybermen's adaptation against gold's neutralizing properties, providing the mechanism for their vengeful plan to destroy Voga. Their exposure forces Kellman's complicity into the open and shifts the Doctor's fight from survival to dismantling an ecosystem of engineered devastation.
