The Motor City Mangler, only appearing in a flashback in "Dark Justice", is a cocky, cannibalistic Serial Killer who kidnaps young women and grinds them into sausage and ribs, having done so to many. When Alex Murphy and John T. Cable investigate his house, the Mangler holds Cable at gunpoint and forces Murphy to drop his gun. Once Murphy complies, the Mangler tries to shoot both him and Cable.
Dr. David Kaydick is an ex-OCP scientist who, fired for his grotesque experiments on human subjects, went into hiding in the slums of Old Detroit. Possessed of a burning rage against OCP for hindering his research, Kaydick fostered a family with a woman named Ann, keeping her as an abused slave with years with an electric neurochip before she finally fled and keeping their daughter Jordan for his own purposes. Kaydick forces Murphy's old partner, Cable, into his service with the same electric chip to torture him into submission while revealing he's used Jordan as an incubator for his magnum opus, the Legion "bio-tech" virus, through which Kaydick intends to unleash to destroy all life on the planet with Delta City as its breakout point. Massacring and brutalizing all those who get in his way either with his own hands or through Cable, Kaydick finally uploads Legion into Delta City's SAINT network before opting to murder everyone else threatening his plans—including Jordan—while laughing and deriding Ann as "just a woman" when she finally confronts him. Seeing it as his right to kill millions of people simply for being spurned from his immoral research, Kaydick is one of the cruelest people to threaten even the polluted setting of Old Detroit.
Dork Age: It was intended by the creators to pull the franchise out of the one it's been in with RoboCop 3, The Series, and Alpha Commando, but many fans felt that despite the return to the dark tone of the first two movies, it didn't help.
Fridge Horror: In the climax, Cable sacrifices his life to save the entire human race from extinction at the hands of Legion by destroying SAINT with an EMP. This would be a touching Redemption Equals Death moment... except the EMP bomb also simultaneously knocks out all of Old Detroit's power, a city shown to run mostly on technology. We even hear the screams of the city from a distance in the ending, but any damage or casualties is reduced to a sardonic "they'll probably blame me for this" by SAINT's creator.
Narm: How both Page Fletcher and Maurice Dean Wint moved in the suits were seen as many fans as ridiculous.
Narm Charm: As earnestly bad as a lot of the things about the miniseries are, you can't help but enjoy how completely over-the-top and unrealistic it gets, even by RoboCop standards.
Special Effect Failure: Most of the effects are pretty lame, but special mention goes to a scene in "Crash and Burn" where RoboCable's butt-plate is barely attached (it must have come loose when they were wrestling in the zen pond).
WTH, Casting Agency?: Many fans reacted negatively to Page Fletcher as Murphy. Among the reasons were the fact that he was shorter than most of the other cast members or even the other actors to play the role (whereas both Peter Weller and Robert John Burke were tall and Richard Eden as of average height) and how Fletcher moved in the suit.
