Brad Lydecker[1] was a Weyland-Yutani Corporation employee and assistant operations manager at the Hadley's Hope colony on Acheron. He was caught up in the Xenomorph infestation that overran the colony in 2179.

Lydecker later perished when the colony was overrun by the Xenomorphs.


On the colony

Lydecker worked as assistant to Hadley's Hope administrator Al Simpson in the main operations center at the colony.[4] He often had to chase children from the operations level, an area from which they were officially barred.

Investigating the coordinates

When prospectors Russ and Anne Jorden called in to clarify whether anything they found whilst investigating coordinates passed on to them from Weyland-Yutani would be theirs to salvage, Lydecker raised the issue with his boss Simpson. Simpson merely asserted that in his personal opinion the Jorden's could lay claim to anything they found.

Xenomorph infestation

Lydecker later perished during the Xenomorph infestation that overran the colony, although it is unknown if he was killed outright or captured by the Xenomorphs and taken to the Hive for impregnation.


  • Lydecker was cut from the theatrical release of Aliens when the studio complained that the film was too long. The scene featuring him was later reinstated for the extended Special Edition.
  • In James Cameron's original treatment for Aliens, the name Lydecker is actually assigned to one of the Colonial Marines, a female Corporal who acts as the unit's medical technician (a role filled by Corporal Dietrich in the final film).[5]
  • The scene featuring Simpson and Lydecker is almost identical to a scene in James Cameron's later film Terminator 2: Judgement Day: an employee flags down a supervisor in a busy office and they walk together, discussing the behavior of their employer — Weyland-Yutani in Aliens, CyberDyne Systems in Terminator 2 — before the more senior man ends their conversation with a line about their employer always responding to sensitive questions with the phrase "don't ask".
  • The headset Lydecker is briefly seen wearing appears to be an unmodified Beyerdynamic Headmicrophone HM 560 (with M560), which is better known as the base of the Head Mounted Sights used in the film.
