Unnamed Borg spheres

This article lists Borg spheres without any known designations.

By appearance

Cyberman alliance cubes

At least one Borg sphere was part of the Borg-Cyberman fleet, which consisted of dozens of Cyber-ships and Borg cubes, during the alliance between the two cybernetic races in 2368. (TNG - Assimilation² comic: "Issue 2")

T'Uerell

The following Borg spheres were part of a Borg Collective which was controlled by the rogue Vulcan scientist, T'Uerell.

Aurelius spheres

Numerous spheres participated in an assault on the Aurelius region. While the Borg cubes assimilated the planets in the region, the spheres were among the other ships which preyed on the impulse transports which were carrying the evacuated civilians. The Borg ships were engaged by a Starfleet task force led by the USS Enterprise-E, which allowed for fifteen transports, carrying the majority of the populations in the Aurelius region, to make it to Starbase 127, where the evacuees were safely transferred to warp-capable ships.

Against Vorel

Three spheres fought alongside a Borg obelisk against a trio of Harpy-class Romulan warbirds led by Subcommander Vorel in the Bajor system. They were destroyed with assistance from a Federation Alliance task force led by the Enterprise-E. (ST video game: Legacy)

Covering T'Uerell

Two spheres were among six Borg vessels which fought alongside T'Uerell's ship, the assimilated Suurok-class science vessel Seleya, against Deep Space 9 and a Federation Alliance task force led by the Enterprise-E above Bajor in the Bajor system. The six vessels were ultimately destroyed, while the Seleya escaped the system. (ST video game: Legacy)

Hayre Expanse

Multiple spheres were among the Borg vessels which were summoned via an unstable transwarp conduit by T'Uerell for her last stand in the Hayre Expanse. Ultimately, they were all destroyed along with T'Uerell aboard the Seleya by a Federation Alliance task force led by the Enterprise-E and the USS Voyager. (ST video game: Legacy)
