This Xenomorph Soldier infiltrated the Bug Stomper while it was on the ground of LV-426. It was responsible for killing the dropship's crew consisting of pilot Ferro and weapons chief Spunkmeyer while in mid-air, which led to the dropship's destruction.
Shortly after the Colonial Marines had secured the areas of Hadley's Hope, Bug Stomper pulled out and set down some distance away from the colony to await fresh orders. This Xenomorph Soldier managed to locate the dropship and slipped aboard the dropship undetected by the crew, only leaving a trail of slime behind. Following a disastrous ambush in the colony's Atmosphere Processor, Bug Stomper was called upon by the surviving Marines for immediate evacuation. The Soldier attacked Spunkmeyer shortly after he entered the dropship. The Soldier then proceed to make its way to the dropship's cockpit where it ambushed Ferro from behind and killed her while Bug Stomper was in mid-air, causing the Cheyenne to crash and killing the Warrior as well. The Soldier's actions not only caused the surviving Marines to lose their APC and much of their equipment, but the Cheyenne's crashing also caused the Atmosphere Processor considerable damage that contributed to its later meltdown and destruction that doomed both the Marines and ironically, its own hive.
