M was a disassembly drone who was deemed weak and "Disunctional" by the rest of her squad and was abandoned. She later encountered Alice who Took some of her parts and caused her left eye to glitch. M just managed to escape and stole a bandana and a cloak from two human corpses which she used to hide her tail and glowy headband thing so she could blend in with the worker drones. She has now begun to come out of her shell and has befriended several worker drones.
