Borg Queen's sphere personnel
List of unnamed Borg drones attached to the Borg Queen's sphere. 

In 2373, a number of Borg drones escaped the destruction of their vessel at the Battle of Sector 001 with the Borg Queen aboard a Borg sphere. The sphere traveled to the year 2063 through a temporal vortex where it was destroyed in orbit of Earth by the pursuing starship .

The Queen and a number of these drones were able to transport aboard the Enterprise where they proceeded to assimilate the ship. The Queen, along with most of these drones, were killed when the ship's warp plasma coolant tanks were ruptured in engineering. 

In an alternate timeline, observed by the Enterprise as they were within the temporal vortex, these Borg were successful in assimilating Earth. ()

Drones encountered in the corridors

First drones sighted  
The security team led by Captain Jean-Luc Picard and Lieutenant Commander Data encountered this first batch of drones as they entered the corridor near main engineering on deck 16. These drones initially ignored the security team as they were not initially perceived as a threat. 

One of these drones was later found in the corridor on deck 16, regenerating in a Borg alcove constructed into the bulkhead. ()

Regenerating drone 

This drone, regenerating outside of engineering, reacted to Captain Picard's attempt to forceably enter the section. It was armed with a heavy, prosthetic arm distinguished by a small, clawed extension and a visible electric spark. ()

Guard drone 

In an effort to prevent entry to engineering, this drone attacked Captain Picard and attempted to assimilate him. Lieutenant Commander Data subdued the drone by breaking its neck and killing it. ()

In 2399, Picard mentally recalled the image of this drone while aboard the Artifact. ()

Herding drone 

This drone was encountered by crewmembers in the corridors aboard the Enterprise-E herding a recently assimilated Starfleet officer to the main assimilation area. ()

MIE Auxiliary Access drones 

In their attempt at suppressing the Borg advance on the upper decks of the Enterprise-E, a contingent of Starfleet security officers encountered a group of six drones in a darkened MIE Auxiliary Access room. The drones were visible, at first, only by the laser light of their eyepieces. ()

Drone in holodeck  

This drone joined the drone of the former Ensign Lynch in holodeck 4, where it was shot by a Tommy gun welding Captain Picard. ()

Drones encountered in engineering

Klingon drone 1 

This Klingon male was present in the Enterprises engine room and was killed when Lieutenant Commander Data punctured the ship's warp plasma coolant tanks. ()

Klingon drone 2 

This Klingon drone, observed in engineering, reacted to the attempted escape of Lieutenant Commander Data, but was called off by the Borg Queen. The drone was likely killed when the plasma coolant tanks were ruptured. ()

In 2399, Picard mentally recalled the image of this drone while aboard the Artifact. ()

Klingon drone 3 

This Klingon drone was stationed in an alcove at the entrance of engineering and observed captain Picard as he entered to face the Borg Queen. ()

Regenerating drones 
Three drones, including one Klingon drone, were observed near the warp core in the Enterprise-E engine room, attached by cables to the ceiling where they were regenerating. These drones were killed when the plasma coolant tanks were ruptured. ()

Skin transplant drone 

This drone was part of the group that transplanted skin onto Data's right arm while he was confined in main engineering. It was also one of the drones who chased Starfleet officers down a corridor. ()

Drones encountered on the deflector dish 
Six  drones were dispatched to the exterior hull of the Enterprise where they constructed an interplexing beacon on top of the navigational deflector. These drones were stopped by an EVA team consisting of Captain Picard, Worf and . ()

One the these drones tried to stop Worf launching the docking clamp and ended up in a hand-to-hand combat with him. Worf cut off his right arm and then killed him by embedding his mek'leth into the drone's neck. Worf later used a cable from the severed limb to seal a puncture in his suit. ()

The fifth drone responded to Hawk's attempt to release the maglock securing the deflector and beacon to the ship, but was shot by Hawk, before floating off into the dead of space. 

The sixth drone – of Klingon origins – also responded to Hawk's perceived, following the loss of the previous drone. However, unlike the previous drone, this drone was successful in attacking and assimilating Hawk. ()

Defrosted drones  

These two Borg drones were found inside a glacier in the arctic on Earth in 2153 by the three scientists of the Arctic Archaeology Team, , , and Moninger. They were buried by ice and snow inside debris from an alien ship.

The scientists moved them to their base camp and studied their physiology and the technological components noting that they were of two different species. Under the microscope they found nanotechnology at work repairing their cell membranes.

During nightshift, Moninger was alone with the two drones when one suddenly started to get a pulse and then started breathing. Drake and Rooney, who were outside for research, noticed screams and phase rifle fire from the module where the two drones were kept. When they arrived at the module only one drone was on the table, the other was gone and they found Moninger on the ground under several pieces of inventory, with pale skin and a moving infection.

When Rooney turned around to get a medical kit, the missing drone was standing behind her and a red light from his eyepiece was covering her. They assimilated the archaeology team and took the debris from their ship, assimilated the transport Arctic One and went away from Earth.

They attacked a Tarkalean freighter and assimilated two Tarkaleans which were brought aboard . The first drone tried to stop the away team from Enterprise later aboard the transport and the second drone was part of the boarding party. Like all the other drones they were killed when Enterprise destroyed the transport Arctic One. ()

Cardassian drone 

A Cardassian Borg appeared in publicity for  but was not seen in the film. (Star Trek: The Next Generation - The Continuing Mission, p. 245)

Corridor drone 

This Borg drone was part of the contingent that boarded the Enterprise-E in 2063, observed in one of the ship's corridors. ()

Three corridor drones 

These three Borg drones were part of the contingent that boarded the Enterprise-E in 2063, observed in one of the ship's corridors, one apparently a former Romulan. ()
