Borg
The Borg are a fictional race of organic cyborgs in the Star Trek universe which have formed over thousands of years. The Borg use nanoprobes to assimilate others, like humans or vulcans, into their group consciousness. The only execption to assimilation are races either too primitve to assimilate (who are ignored) or races too dangerous to assimilate (who are destroyed). The Borg's group consciousness is led by the Borg queen, who's role is similar to that of a queen bee in a bee hive.
