M is a murder drone who is the strongest, smartest, and the leader of his own red squad. He has some similar personality of what Serial Designation J has. He's arrogant, and hardworking murder drone. However, he's sometimes edgy. He also sometimes shows affiliation towards his fellow murder drones. His job is to "dispose" the worker drones he encounters. He appears to be having a red color instead of yellow since disassembly drones are mostly yellow color traditionally.
