The group first appeared in South America in 1987, following Alan "Dutch" Schaefer's encounter with the Jungle Hunter in Val Verde. A team led by Peter Keyes tracked Dutch to a hospital where he was being treated for apparent radiation sickness, and from him learned what had happened in the jungle. A research squad was sent into Val Verde to investigate further, discovering the site where the Jungle Hunter had detonated its Self-Destruct Device, as well as evidence of a spaceship launch — unknown to the team, the Jungle Hunter's ship had automatically returned to Yautja Prime upon it's owner's death. Dutch later disappeared, and the Val Verde operation was closed down with frustratingly little hard evidence gathered.
