Lydecker was the assistant operations manager at Weyland-Yutani's Hadley's Hope colony on LV-426. He was also a close friend to colony manager Simpson.
History[]
Lydecker informed Simpson about the vague orders given by Burke regarding the colony's duty to find the derelict ship, he also scolded a child riding a tricycle for going into the observation center.
Al later sends colony "wildcatters" Russ and Anne Jorden to the area beyond the colony to search for the derelict ship. Russ and Anne eventually discovered the derelict ship and went inside the derelict spacecraft to investigate, only to discover the ancient alien egg nest, where Russ was then implanted by a facehugger.
Lydecker was presumably impregnated or killed by the Xenomorphs when they infested the colony.
