The Borg in Star Trek are terrific beings that function as a collective assimilating any humanoid life by adding nanites and creepy mechanical appendages. The Borg add a scary element to The Next Generation, Voyager, and First Contact. It is interesting that Capt. Picard can hear the Borg due to being implanted with their nanites.
Thank goodness the crew rescued Picard and 7 of 9 for that matter. I think her character is great in Star Trek Voyager, she brought a lot of interesting stories to the show.
