In the Star Trek television series, the Borg probe ship is used by the Borg to gather information before primary ships are brought in. In one episode the USS Voyager was able to destroy the ship with a single photon torpedo. These ships are capable of transwarp speeds.
Borg cubes are as powerful as they are immense, with a single cube being capable of annihilating entire fleets of advanced (e.g., Federation Starfleet) ships, and are matched by few others (i.e., "Species 8472").
In 2375, a Borgprobe confronted the USS Voyager in an attempt to assimilate the ship and its crew.
A Borg scout ship was found by the crew of the Enterprise-D on a moon in the Argolis cluster in the episode "I, Borg" (TNG).
The Borg's interlink and use of nanotechnology are also similar to that of the Conjoiners from Alastair Reynolds's Revelation Space series of novels, while their ability to adapt to any attack resembles a faster version of the Inhibitors' ability in the same series.
Borg nanoprobes are injected into the bloodstream of a victim by a number of tubules (usually two) that spring forth from the top of the hand (or some other extremity) of a Borg drone.
The Borg are born as wholly organic beings and are melded with hardware to become biomechanical hybrids.
