Blue Bloods/YMMV


 * Complete Monster: Richard Reed, from season 1's "Re-Do", a vicious Serial Killer and rapist of women, is a misogynistic sadist who thinks all women are his to use and abuse. He later has his conviction overturned because a lab tech screwed up the protocols. With help from his fan club, he terrorized his surviving victim into silence and decided to let one of his fanboys have her. Even his own kin are not safe as Richard beats his sister and ties her up for saying something she "shouldn't have." Later he slits a janitor's throat and attempts to perform his usual MO on Erin Reagan, the ADA who convicted him, before she is saved by Frank. Void of any redeeming qualities or mitigating factors, he stands as one of the very worst the Reagan family went against.
 * The Phantom, real name Donald Washington, from season 2's "The Life We Chose", is a cold-blooded crack dealer and murderer. In the beginning of the episode he ruthlessly shoots detective Cruz and kills Detective Gates, who pleads that he has three kids and to which the Phantom replies "Too bad for them". This shocks even his own cohort who was only planning on robbing them. The Phantom would later kill his cohort when he didn't need him anymore. He later goes after other members of Task Force Apache, the police sting that sold him out planning on killing all of them to keep his drug dealing business running smoothly. Greedy and wishing to make his vile business run smoothly, he cares for no one but himself and is an utter psychopath.
 * Uri Denko, from season 2's "Working Girls", is a ruthless Arms Dealer who Erin is prosecuting. A cold-blooded sadist who has no problem executing a man's wife in front of him in their living room over a business dispute. He would later threaten the man's children in a courtroom outburst to scare him into not testifying but still has him killed anyway after the threats scare him into running. He then puts out a hit on the surviving witness and hounds her mercilessly even going so far as going after her grandmother back in Russia as well. A sociopath of the highest order, he would step on anyone who gets in his way.
 * Santana, from season 3's final two episodes The Bitter End and This Way Out, is a vicious gang leader of the Los Lordes gang. He and his gang are responsible for turning the Bitterman projects into a hellhole and hounding the residents, making them scared for their lives to the point that one young mother commits suicide with her son to get away from him. After her death and Detective Danny Reagan's attempts to take them down, he declares war on the police department and arranges for ambushes, one of which kills Jamie's partner and friend Vinny. He later takes advantage of a mentally-impaired man by having him shoot Mayor Poole by having him think it would be a harmless prank. The shooting would leave Poole paralyzed and in a wheelchair for the rest of his life. After his girlfriend is arrested with his drugs, he panics and puts out a failed hit on her in prison.
 * Crowning Moment of Funny: Jamie swallows the thumbdrive to hide it. Turns out Jamie swallowing things is a running gag in the family.
 * Like You Would Really Do It: Frank is shot at the beginning of "Dedication" in a drive by. He lives.
