Status: ACTIVE
Threat Level: ████ (Severe)
Primary Habitats: Artificial containment paddock, controlled environments.
Recent Reports: Multiple vocal mimicry events, two confirmed fatal incidents.
Encounter Protocol: Do not respond to any voice originating from within or near containment without visual confirmation of source. Maintain minimum 15 m distance at all times.
Species Name: Mutanocturnus raptor (The Mock)
CRC Species Code: C-11
Presumed Origin: Genetic splicing program between CRC facilities. Base genome derived from raptor (Deinonychus sp.) with integrations from Snakling, jaguar (Panthera onca), gecko (Gekko gecko), and supplementary gene sources (unknown).
Discovery Date: ██/██/████
Classification: Genetically Engineered Apex Predator
Observed Activity Period: Primarily nocturnal; exhibits opportunistic diurnal activity during low-human-presence periods.
General appearance:
A muscular, charcoal-scaled predator standing 2.1 m tall and 5.2 m in length, with a long counterbalancing tail and a sail-like dorsal fin that aids in climbing stability and rapid directional shifts. Its head is raptor-like but elongated, with sensory pits along the jawline. Limbs are proportioned for explosive bursts of speed and vertical pouncing.
Juvenile Form:
Smoother sail development, reduced muscle mass. More erratic in behaviour, less controlled in mimicry.
Adolescent–Adult Form:
Fully developed sail, thickened tail base for balance, visible scarring from both experimental procedures and containment attempts. Lower vocal register and refined mimicry skills.
Distinctive Features:
• Charcoal-black, non-reflective scales for stealth.
• Sail structure aiding in balance and wall/ceiling climbing.
• Enlarged forelimbs with jaguar-like gripping strength.
Sensory Profile:
• Potentially blind or partially sighted; compensates with enhanced auditory mapping.
• Detects vibrations through limbs and tail for prey tracking.
Predatory Behavior:
• Utilises perfect vocal mimicry to lure targets into range.
• Capable of extended stalking without movement for hours.
Aggression Drivers:
• Proximity to humans, especially known researchers.
• Vocal responses to its own mimicry attempts.
• Sudden changes in environment (lighting, vibrations, unfamiliar smells).
Regeneration: Moderate; recovers from superficial injuries within hours, deeper wounds within days due to Snakling DNA.
Weaknesses: Susceptible to extreme cold; respiratory distress in prolonged sub-zero environments. Early genetic design errors cause occasional seizures under bright strobing light.
Vocalization: Can mimic any voice it has heard with perfect cadence, tone, and emotional inflection. Will often “test” mimicry before using it for luring.
Cognitive Capacity: Comparable to or exceeding human problem-solving ability; shows understanding of locks, cameras, and containment systems.
Incident [C-11-05] — “The Janitor’s Wife”
Summary: Late-night cleaning shift. Janitor reports hearing his wife’s voice from inside C-11 containment, claiming to be stuck and sedated. The wife had never been to the facility. Janitor opened secondary access door before main paddock gate; creature remained inside but inflicted severe injuries before retreating. Janitor found alive but incoherent, muttering, “It took its time.”
Incident [C-11-06] — “The Missing Researcher”
Summary: Researcher ████ failed to report to morning briefing. Security logs show them responding to a co-worker’s voice from containment corridor at 03:17. No further footage exists beyond them entering an unsecured service hatch. Only personal effects recovered. DNA traces matched to C-11 oral fluid samples.
• Install dual-layered auditory dampening between paddock and service corridors.
• Prohibit all non-essential personnel from solo night shifts near containment.
• Maintain environmental temperature below 5°C during any maintenance period.
• Equip all staff with non-voice, coded light-signal communication when in proximity to C-11.
