Most Mega-City citizens are generally too lazy to get off their backsides and do the menial work performed by these semi-sentient robots.
Robots have 'AZI-MOV protocols' forbidding them from harming a human. Yet, some break their programming. Mega-City One has been hit with two major robot-related conflicts. The first was initiated by the rogue 'Call-me-Kenneth' unit. A bloody campaign of extermination against the 'Fleshy Ones' ensued. The second was precipitated by the arch-criminal Nero Narcos, who unleashed hordes of Assassinator Droids in his bid to seize control of Mega-City One.
Despite these incidents, robots continue to be an indispensable part of Mega-City life. With Mega-City One's population decimated by recent events the presence of robots as a tireless workforce has become ever more important.
