Re: Where in the World Was Nero/Narada? [spoilers]
Countdown comics (#3 I think?)...Narada was just a simple Romulan mining ship to start with but after the destruction of Romulus, Nero kills the remaining Romulan High Command and finds the location of a secret weapons facility where the Romulans have been re-engineering Borg technology (presumably from their war with them stretching back to before Season 1 TNG). They "assimilate" the Narada and it becomes the tentacled, V'ger-esque ship in the movie.
Where was it ever said that it was a borg ship?
