Beverly Crusher's Containment Field
Beverly Crusher develops this field on the Enterprise bridge and deploys it in Cargo Bay Four, where it floods the space and erects an invisible barrier trapping Ux-Mal anionic energy rings alongside possessed hosts Troi, Data, and O’Brien. Riker orders its activation against the growing possession threat, Ro pairs it with a plasma shock for expulsion, and Picard leverages it in a bluff by threatening collapse, forcing entity surrender without host harm.
