Re: What did/does the Borg say to the kazon whenever they cross paths?
The Kazon could have been effective villains once we got over their hairstyles. They were based on L.A. gangs, who had weapons equaling or better than those carried by LAPD. Instead, the Kazon were technologically inferior to nearly every other race seen in the Delta Quadrant (except for that planet where they stranded the crew).
