Once a zoologist studying bat species in Indonesia, he encountered the legendary Ahool during an expedition, barely surviving an attack that left distinctive scars across his back. His near-death experience led him to recognize similarities between the Ahool and other blood-drinking creatures worldwide, eventually bringing him to Latin America where Ixchel recruited him for his unparalleled expertise in tracking aerial predators and his firsthand knowledge of creatures similar to the Chupacabra.

The Ahool Stalker possesses exceptional night vision and hearing, having trained himself to detect subtle air movements and high-frequency sounds imperceptible to others. He utilizes custom-designed climbing equipment allowing rapid ascent of ancient temples and tall trees, providing vantage points from which he tracks prey using techniques inspired by bat echolocation principles. His specialized knowledge of flying predator hunting patterns enables him to anticipate the Chupacabra's movements before ground trackers can, making him an invaluable forward scout for the Shadowmane Hunters.

Within the Shadowmane Hunters, he serves as the primary aerial reconnaissance specialist and night operations expert, using elevated positions to map the Chupacabra's territory and movement patterns while advising the team on hunting strategies based on his unique understanding of nocturnal predator behavior. His unorthodox tracking methods complement Ixchel's more traditional hunting techniques, creating a comprehensive approach that leaves the Chupacabra no place to hide.
