The Borg is a faction of Bobs that cosplays as the cyborg antagonists of Star Trek: The Next Generation.
They are described as isolationists who, like Starfleet and the Skippies, advocate for minimal contact with other species.
Locutus is the only Borg Bob mentioned by name in Heaven's River.
They volunteer to help with the search for Bender, by designing the Quinlan androids.
