En (N)

Worker drones worked for the humans on the planet Copper-9, but after an accidental explosion of the planet's core, an eternal winter descended on the planet, the humans died out, and the worker drones began to establish their own order and produce offspring in a similar fashion to humans. But the humans from the planet sent killer drones to Copper-9, which mercilessly killed the worker drones, surviving on their oil. And so, for many years, the workers lived in an underground bunker behind iron doors that the killer drones couldn't break down. But the Uyuan drones lived in abandoned places or in their capsules from which they had flown to Copper-9. But there was one killer drone who stood out among them: his name was En. En's palms can be changed into any weapon, he has iron wings that can also be used as weapons, and a tail with a syringe of acid at the end. Personality: Too kind for this cruel world, very sweet, naive, innocent, a bit of a wimp. He doesn't like killing, but if a loved one, or more precisely a worker, is in danger, he will attack. So far, En doesn't have any close killer drones or even worker drones. Everyone is wary of him and considers him a weak and stupid idiot.
