The Maitre (French: "Master") are documented in the alleged Soviet/KGB intelligence handbook known as the Book of Alien Races as among the most dangerous non-human species catalogued. Their profile in the handbook — along with witness accounts from researchers studying the most traumatic categories of abduction and unexplained biological phenomena — positions the Maitre as an apex-predator NHI operating independently of the Grey hierarchy, engaged in systematic biological exploitation of Earth's biosphere.
The Maitre entry in the alleged Soviet KGB intelligence handbook — claimed to have been translated and published in English by Dante Santori and Petro Kichkaev — is one of the most detailed in the document. Key points from the entry:
From the Russian Alien Races Book entry and corroborating witness accounts:
The Maitre behavioral profile, as assembled from the handbook entry and researchers who have studied the most severe abduction and mutilation cases, is strikingly consistent:
In September 1988, a male body was discovered near the Guarapiranga Reservoir in São Paulo, Brazil. The official autopsy by Dr. Cuenca documented surgical removals of body parts with unusual characteristics: eyes, ears, lips, tongue, and genitalia removed with precision incisions showing no signs of struggle, hemorrhage, or standard surgical technique. Internal organs removed through small incisions — the abdomen apparently drained of organs through cuts far smaller than would be required by conventional surgical access. Crucially, the wounds showed characteristics that Dr. Cuenca described as inconsistent with any known surgical technique and suggesting an unknown cutting technology. The case was investigated by researcher A.J. Gevaerd and documented in the Brazilian UFO Magazine. The methodology is consistent with what Maitre operations are described as in the Russian handbook.
The pattern of surgical precision, organ-specific removal, bloodless incisions, and laser-cut precision documented in American cattle mutilations by investigator Linda Moulton Howe (beginning with her 1980 Emmy-winning documentary Strange Harvest) is consistent with the Maitre biological extraction methodology described in the handbook. Howe's investigations produced veterinary and laboratory analysis confirming the precision and anomalous nature of the incisions, and law enforcement documentation from multiple states confirming the phenomenon's reality.
Filiberto Cardenas disappeared from a roadside in Hialeah, Florida on January 3, 1979, in front of three witnesses including his family. He returned hours later reporting an abduction by beings described as distinctly taller and more intimidating than the classic Grey type — pale, elongated cranium, deeply unsettling presence. Investigated by researcher Virgilio Sanchez-Ocejo, the case includes multiple witness statements and physical sequelae from Cardenas' experience.
Researchers who have identified a possible Maitre presence in case files consistently note the following distinguishing characteristics from standard Grey encounters:
This profile documents the Maitre as described in the Russian Alien Races Book (provenance unverified) and in associated case research without endorsement. The Guarapiranga case autopsy documentation is factual; the NHI interpretation is one of several explanations proposed. Cattle mutilation as a documented phenomenon is presented factually; the Maitre connection is a researcher hypothesis. No conclusions about the literal reality of described entities are made herein.
