Harry forces Broton to reveal Skarasen truth

Harry corners Broton aboard the Zygon spaceship and extracts the horrifying origin of the Skarasen—a creature whose embryonic form was transported to Earth as the sole source of Zygon survival. Broton boasts of how the Skarasen was transformed through cyborg integration into an unstoppable weapon, revealing both the Zygons' existential dependency on this monstrous resource and their ruthless engineering of its lethal capabilities. This confrontation binds the Doctor’s mission to an environmental and biological catastrophe in which Earth has become the battleground for two species’ survival, escalating the threat beyond a simple invasion into a shared doom if either side fails to prevail.

Human Weapons

Broton dismisses human weapons as 'puny' and 'mere pin pricks,' categorizing all of humanity's technological arsenal as irrelevant against the Skarasen's cyborg armor. This rhetorical dismissal underscores the futility Harry faces if forced to confront the creature directly.

Skarasen

The Skarasen is referenced in its embryonic form as the Zygons' sole survival resource, then described in its engineered cyborg state capable of absorbing all human weaponry. The creature's dual nature forms the core of Broton's threat — its destruction would doom the Zygons while its unchecked existence dooms humanity.

Before: Existed as an embryonic lifeform transported from the destroyed Zygon homeworld, now integrated into a cyborg weapon aboard the ship.
After: Still exists as an engineered cyborg weapon, with its destructive capacity emphasized as invulnerable to Earth's weapons.
Zygon Nuclear Missiles

Though not physically present, Zygon nuclear missiles are implicitly included in Broton's dismissal of human weaponry. He reduces all Earth-devised armaments—including these missiles—to insignificance against the Skarasen's cyborg transformation.
