Keller Machine

Not applicable (as an object/artifact), but its absence radiates a sense of impending danger and urgency, amplifying the tension in the scene.

The Keller Machine does not possess emotions, but its actions convey a sense of relentless, single-minded purpose—hunting down sources of evil to feed on. Its 'state' is one of uncontrolled aggression, driven by its programming to seek out and destroy malevolence, regardless of the collateral damage.

Coldly ravenous; its actions are driven by an insatiable hunger for evil impulses, devoid of remorse or hesitation. The Machine operates with mechanical precision, treating the officers’ minds as mere sustenance.

N/A (Antagonist entity, but its 'behavior' can be described as menacing yet vulnerable in Barnham’s presence.)

None (as a machine), but its behavior suggests a 'hunger' for evil that is frustrated by Barnham’s presence. The silence when Barnham is near is eerie, almost like a predator sensing prey it cannot consume.

None (as a machine), but its behavior suggests a ravenous, territorial response to the removal of its neutralizer—like a beast deprived of its prey.

The Keller Machine doesn’t have emotions, but its throbbing suggests a predatory, almost hungry state. It’s as if it’s absorbing the negative energy of the confrontation—the Master’s frustration, the Doctor’s distrust, the urgency of the moment. Its passivity is deceptive; it’s a ticking time bomb, waiting for the right moment to unleash its full power.
