DJ

DJ, shortened form of Don't Join, was a male human slicer with a stutter who resided in the galaxy during the war between the Resistance and First Order. DJ was a "shady" individual who held "unclear allegiances." Despite this, he performed hired work for the First Order, betraying Finn and Rose Tico, who had taken him under their wing for a slicing mission.

Biography
When Finn and Rose Tico are sent by Maz Kanata to Cantonica, to find the Master Codebreaker, they are soon arrested by the Canto Bight police force because of a "parking violation." They eventually end up in the prison cells where DJ is currently serving time for a past crime (judging by his comments, it appears to be either for hacking or thievery). He eavesdrops on Finn and Rose's predicament and offers his assistance, although the two shut him down due to his eccentric demeanor. To prove his talents, he effortlessly opens the cell containing them (which due to the wealth of Canto Bight was very technologically advanced) and walks out only to run into BB-8. Upon seeing BB-8 fend off the guards with fast-firing casino chips and his taser, DJ becomes very impressed with the feisty robot, and lets him tag along unaware that it belongs to Finn and Rose.

Later, due to the commotion caused by the two on the streets of Cantonica, he appears in a stolen ship along with BB-8 and offers to rescue Finn and Rose. Still reluctant, they only accept due to the heavy pursuit of the Cantonica police, and they all manage to escape.

Finn and Rose explain the nature of their mission to DJ via a call through Poe Dameron and ask him if he's able to do what they need. He says he can and agrees to help them for a hefty price, which includes the necklace Rose is wearing. Despite Finn's angry outburst, Rose agrees to his terms. Afterwards, Finn personally confronts DJ and tells him that the necklace belonged to Paige Tico, Rose's sister who sacrificed herself for the Resistance. DJ coldly remarks that whether it's the Resistance or First Order it doesn't really matter to him, as both sides of the war serve to benefit the rich, and tells Finn to not join (hence the name DJ).

Disguising themselves as First Order personnel, they infiltrate the ship and manage to get past all the guards except for BB-9E who spots BB-8 under a flimsy droid disguise. Once they reach the location, DJ uses the necklace given to break into the wiring of the ship, disables a locked door leading to the tracking system, and promptly returns the necklace to Rose once he is done with it, proving that he isn't entirely without morals. But once reaching the room with the tracking system, a lot of imperial personnel appear to block the exit, presumably called by BB-9E and they are all led by Phasma herself, sarcastically greeting Finn. Upon being brought to the main hangar, DJ gives Armitage Hux and Phasma the information that the resistance are fleeing towards Crait and this allows the artillery to attack and destroy most of the transport pods deployed by the resistance. This earns DJ his freedom, as well as a larger sum of money than what the resistance could've offered him. DJ explains to Finn that they will hit you today, but you can get them back tomorrow, showing his selfish and vengeful nature. He soon departs the ship, presumably before Amilyn Holdo's hyperspace maneuver which sees the hangar go up in flames.

Personality and traits
DJ felt that larger causes were for fools, society being a machine looking to turn everyone into a cog. He felt this was true of any organization, be it the First Order, Resistance, or New Republic. He considered all such causes to be meat grinders that chewed up their followers with the same disinterest.

Behind the scenes
"Maybe you could find him in a Bob Dylan song or a Tom Waits song. Or maybe in a Dostoyevsky novel. You'll find DJ in one of those stories. You don't know what he is. But that's the idea... You don't know if he's good or bad."
