Auton
primary

None (as a machine), but its collapse symbolizes the fragility of the Nestene’s control when faced with the Doctor’s ingenuity.

The Auton strides forward on its patrol, its plastic limbs moving with eerie precision as it scans the factory floor. Its hollow eyes reflect the dim light, and its hands twitch slightly, ready to transform into weapons at a moment’s notice. As the Doctor activates the sonic screwdriver, the Auton’s body locks up, its movements jerky and uncoordinated before it collapses into a heap of inert plastic. There’s no sound, no cry—just the sudden, silent defeat of a machine designed for destruction. The Auton’s collapse is a stark reminder of its vulnerability, a chink in the Nestene Consciousness’s armor.

Goals in this moment
  • Patrol the factory and eliminate any threats to the Nestene Consciousness’s invasion.
  • Maintain the illusion of invincibility to instill fear in human targets.
Active beliefs
  • Its mission is absolute, and it operates without question under the Nestene’s command.
  • It is invulnerable to conventional weapons, a belief that is shattered by the sonic screwdriver’s frequency.
Character traits
Mechanical and relentless Vulnerable to targeted frequencies (a flaw in its design) Silent and expressionless (yet menacing) A pawn in the Nestene Consciousness’s invasion
Follow Auton's journey

Tense but increasingly trusting—her initial skepticism is giving way to relief and admiration as the Doctor’s plan succeeds, though she remains physically alert to the dangers around them.

Liz remains pressed against the factory wall, her breath shallow and her muscles taut as she watches the Auton’s advance. When the Doctor gives the signal—‘Now!’—she tenses further, her eyes locked on the collapsing Auton. The Doctor’s triumphant remark draws her gaze to him, and though her expression is still tense, there’s a flicker of relief in her eyes. She doesn’t speak, but her posture softens slightly, signaling her growing trust in the Doctor’s methods. Liz is the grounded counterpart to the Doctor’s flair, her skepticism giving way to cautious optimism as she witnesses his brilliance firsthand.

Goals in this moment
  • Stay safe and avoid detection by the Auton patrol, relying on the Doctor’s lead.
  • Witness and internalize the Doctor’s tactical success to solidify her belief in his unorthodox methods.
Active beliefs
  • The Doctor’s scientific intuition and improvisational skills are assets, even if they challenge conventional military or scientific protocols.
  • Trusting the Doctor’s approach is essential for their survival and the mission’s success, though she remains vigilant.
Character traits
Observant and attentive Cautiously optimistic Grounded and skeptical (but yielding to evidence) Physically tense but emotionally resilient Trusting in the Doctor’s abilities under pressure

Exhilarated triumph masking underlying urgency—his playful tone belies the high stakes, but his body language radiates the thrill of outsmarting the enemy.

The Doctor crouches in the factory shadows, his body coiled with tension as he tracks the Auton’s approach. His fingers move with precision over the sonic screwdriver, adjusting its frequency until the device emits a high-pitched hum. As the Auton seizes and collapses, he springs into action, his voice sharp with command—‘Now!’—before shifting to a triumphant, almost teasing tone as he addresses Liz. His posture is confident, his movements fluid, betraying none of the urgency that must have gripped him moments before. This is the Doctor at his best: improvisational, inventive, and unshakably sure of his own genius.

Goals in this moment
  • Neutralize the Auton patrol to secure their position in the factory.
  • Demonstrate the effectiveness of the sonic screwdriver as a weapon against the Nestene threat, validating his approach to Liz and UNIT.
Active beliefs
  • The sonic screwdriver’s frequency can disrupt the Autons’ plastic composition, a belief rooted in his scientific intuition and past experiences with alien technology.
  • Liz’s trust in his methods is crucial for their partnership and the broader mission, so he seizes this moment to reinforce her confidence in him.

Doctor's Sonic Screwdriver (Auton Deactivation Mode)

The sonic screwdriver is the linchpin of this event, wielded by the Doctor with surgical precision. Initially, it hums softly in his grip as he adjusts its frequency, its blue glow casting eerie shadows on the factory walls. When activated, it emits a high-pitched, almost ultrasonic whine that disrupts the Auton’s plastic molecular structure. The device’s success is immediate and decisive—the Auton seizes, its limbs locking before it collapses into a lifeless pile. The sonic screwdriver isn’t just a tool here; it’s a symbol of the Doctor’s ingenuity and a game-changer in the fight against the Nestene. Its effectiveness validates the Doctor’s approach and offers a tangible strategy for dismantling the Auton threat.

Before: Clutched in the Doctor’s hand, its frequency dialed to an initial setting as he tracks the Auton’s movements. The device is active but not yet at the critical frequency needed to neutralize the threat.
After: Still in the Doctor’s possession, now confirmed to emit the correct frequency for disrupting Auton plastic. Its glow is steady, and the Doctor’s grip is confident, signaling its readiness for further use in the broader conflict.

Places and their significance in this event

Factory Floor

The factory floor serves as a battleground of shadows and tension, its vast, empty space stripped of machinery and life, leaving only the echoes of footsteps and the hum of distant machinery. The Doctor and Liz press themselves against the cold metal walls, their breaths shallow as they evade the Auton patrol. The dim lighting casts long, shifting shadows, turning crates and discarded equipment into potential hiding spots or obstacles. When the Doctor activates the sonic screwdriver, the factory’s acoustics amplify the high-pitched frequency, making the Auton’s collapse feel almost anticlimactic in the vast, hollow space. The factory is more than a setting—it’s a character in its own right, amplifying the stakes and the Doctor’s triumph.
