Murder Drones
Here is some spoilers because i am a nerd but people who have watched it please read this stuff is important if any bit of the show confused you. If a drone is treated unfairly and poorly by their owner they have a 0.01% chance of turning into a a solver drone. This is what happened to cyn. Cyn did get saved by Tessa because Cyn got trapped in a junkyard with dead drones in there. Cyn just killed Tessa, She did need another host though. Uzi got it from her mother, Nori and Doll got it from her mom Yeva. Cyn was siblings with N, V and J and Cyn turned them into Disassembly drones and that's why their eyes are yellow. Cyn sent them to kill all humans because the humans made her a solver drone. Cyn hated them so much that she tried to kill all of the planets with the solver. Luckily she didn't because Uzi won in the scene with the banger music when they were fighting. Cyn is trapped in Uzi tail now.
