Minor spoilers for Star Wars: The Force Awakens follow. If you have seen Star Wars: The Force Awakens, chances are you remember the Stormtrooper that gave Finn quite the run for his money. Turns out this character that we will probably never see again has a name and his own complete back story and Disney has provided us with some information about our favorite side character on StarWars.com! Part of the reason he shouts the now over-quoted line, “TRAITOR!” is because Finn trained alongside TR-8R whose real name is FN-2199, also known as Nines to his friends.
The article goes on to talk about why Nines is so damn cool, “There’s a reason that Nines gets to use an awesome weapon (which is called a Z6 baton). He’s riot control, and part of an elite squad that enforces order or squashes uprisings. While their weapons are non-lethal in theory, the Z6 can definitely cause harm or kill an opponent when used with brute force.”
The character can be found in Greg Rucka’s novel, Before the Awakening. Who knew a character we had never seen on-screen before could have so much history?
