Zaphra Gas
Lobos directs guards to pump Zaphra gas, a paralytic agent with lethal potential, into Building 6-2's ventilation. This targets Barbara and Vicki, the rebel women holding out there. The Commander recoils at the order's brutality, while the gas looms as an invisible threat later mentioned by the Commander at Morok HQ to flush escaped aliens like Ian. Lobos deploys it with cold precision, turning the building into a death trap.
