Goliath
From Memory Alpha, the free Star Trek reference.
Goliath was a Biblical figure who was slain by David, despite the latter's smaller stature and inferior weapons.
In 2376, The Doctor on the USS Voyager determined that a pathogen had killed all the adult Borg drones on a cube in the Delta Quadrant. In showing the pathogen to Captain Kathryn Janeway and Tuvok, The Doctor remarked, "Behold! The David that slew our Goliath." (VOY: "Collective")
