The SCP Foundation's comprehensive internal inquiry into SCP-FAE-MTN-1733 (Heidis) has revealed alarming new insights, significantly elevating the threat level and complexity of these anomalies. The investigation, spearheaded by Dr. Abigail Potina, confirmed that "Heidis" variants, along with new Hybrids "Claras", "Peters" variants, and the more dangerous "Grandfathers" class, exhibit advanced intelligence, coordinated predation strategies, and powerful cognitohazardous abilities. The most notorious incident involved an Alpha variant, whose prolonged infiltration exposed severe internal security flaws, prompting the Foundation to initiate immediate biometric and cognitohazard detection upgrades.
The investigation also detailed significant unethical hybridization activities by the anti-Foundation Black Marlin Initiative (BMI), a rogue multinational entity operating out of their sub-oceanic facility. BMI, has conducted covert biological and memetic weaponization experiments, resulting in severe containment challenges and ethical violations. BMI classifies anomalies under its own distinct "PAX" system, with several high-risk entities which the Foundation is actively investigating and monitoring through the Special Investigative Service (SIS).
