Corporal S. Baroski, nicknamed "The Experience", was a member of the United States Colonial Marine Corps aboard the USS Sephora when it discovered the USS Sulaco orbiting above Acheron (LV-426) in 2179.


Corporal Baroski took shelter in the Origin Facility after the crash. He was a huge problem for the Weyland-Yutani security force, until he ran out of ammo.
