10 Star Trek Villains Who MUST Get Their Revenge

10. Maj Cullah

Star Trek: Voyager featured the Kazon, various groups of thuggish aliens, based on LA gangs. They were divided into different sects, all of whom traditionally went to war with each other on a dime. When the USS Voyager arrived in the Delta Quadrant, they quickly found something they could agree on: they really, really didn't like that Starfleet ship or crew.

Maj Cullah of the Kazon Nistrim came the closest to destroying the dreams of this stranded ship. With a lot of help from the turncoat Seska, he managed to commandeer the ship, stranded its crew on a nearby planet, and set about becoming the dominant force in his corner of the galaxy. Thankfully, he was thwarted by Tom Paris, Lon Suder, and some helpful Talaxians. 

Still, despite Seska's death as the ship was being retaken, Cullah survived. The Kazon are not traditionally known for letting things go. The Kazon are still out there, evidenced as recently as the pilot episode of Star Trek: Prodigy. With that show bringing the action back to Cullah's part of the galaxy, he is presented with the opportunity to right his perceived wrongs. After all, in a culture dominated by 'Alpha Male' nonsense, losing his prize, via the aforementioned, back to Janeway must still smart, years after the fact. 

He may not be the greatest tactical leader in the galaxy, but he also seems like someone who would do whatever it took to save face. We may not have seen the last of him.
