Murder Drones, Season 2

Uzi, N, and V have barely settled into a shaky peace when a new Disassembly Drone, the enigmatic and charmingly sinister X, crashes into their lives. But X is more than just another murderbot; he's a relic of a terrifying human past, a living ghost with a direct line to the tragedy that created them all.

As a mysterious killer with a crimson tail stalks the colony's halls, the drones are forced to ally with their oldest enemy, J, to survive. Their investigation will plunge them deep into the planet's buried secrets, uncovering a forgotten bunker filled with Nazi war machines and a primordial evil older than the Absolute Solver itself.

Now, Uzi must grapple with a new voice in her head, V confronts a dangerous new attraction, and Lizzy makes a deal with a devil that could burn the world down. To save their future, they'll have to face the horrors of the past, before a forgotten protocol named A1 awakens and finishes what it started.
