Urbankan Conversion Cubicle

A sterile, transparent-walled chamber designed for forced robotic conversion, its cold metal frame gleaming under sterile white lighting. Nyssa is wrestled inside by armored hoplites, her limbs strapped down by technicians as a robotic helmet descends to seal her head. The cubicle’s clinical enclosure amplifies the ritual’s horror—the transparent walls frame her struggle but contain her completely, while the whispered countdown of Lin Futu’s five-minute timer marks the irreversible erasure of her human mind.

Nyssa forced into robotic transformation

Nyssa is wrestled into the metal-framed cubicle, her limbs forcibly strapped down by technicians as the helmet clamps into place. The chamber’s transparent walls frame her captivity, transforming it into a public spectacle of mechanical subjugation.

Before: Empty and ready in the Mobilitary’s conversion bay

After: Occupied by Nyssa in restraints, bathed in sterile white light and poised for robotic conversion

S22E2 · Attack of the Cybermen Part 2

Cyber Controller arms for final strike

The Partial Conversion Chamber alcove becomes a cage for Lytton, its cold blue light pulsing with unstable conversion energy. The restraints clamp tighter as he struggles, their mechanical servos amplifying his distress. The alcove’s mechanism hums ominously, sensing deviation from protocol and struggling to complete his transformation.

Before: Empty and silent, prepped for new subjects, its conversion tracery dormant

After: Active and glowing, binding Lytton midway, his presence creating a dangerous feedback loop in the conversion ritual

S22E2 · Attack of the Cybermen Part 2

Cybermen secure temporal escape preparations

The Partial Conversion Chamber Alcove holds Lytton under restraints as the cybernetic augmentation process accelerates despite emergency cooling protocols. The alcove’s glowing walls pulse with unstable neural energy, marking both his degradation and the device’s malfunctioning state.

Before: Active chamber with restrained subject, unstable energy bleeding out

After: Same state, transformation still incomplete and volatile
