Ranking the Most Horrific Major UnSubs on ‘Criminal Minds’

Criminal Minds UnSubs

The BAU doesn’t always get the job done (right away, at least).

Over 15 seasons of the original run of Criminal Minds, the same UnSub did occasionally appear more than once. And in some cases, those offenders left a lasting impression on at least one member of the team. When better to take a look back at those than on the 20th anniversary of the series premiere (September 22, 2005)?

Since then, the series has returned for a continuation, Criminal Minds: Evolution, on Paramount+, and some of those UnSubs have certainly been memorable. But there’s nothing like going back to where it all started. And so, TV Insider has ranked the major UnSubs — some are Big Bads, while others will always be remembered by fans for the heinous acts they committed in their episodes — of the CBS drama’s original run from least to most horrific and memorable.

Scroll down to see where killers like Mr. Scratch, Foyet, and Frank land.

9. Ian Doyle

If Doyle (Timothy V. Murphy) had actually killed Prentiss (Paget Brewster) — instead of almost succeeding in doing so — he might be higher up on this list. Still, the team thought she was dead for some time, and as soon as he first showed up, it was only a matter of time before he struck in his quest for revenge for what he thought was the death of his son.

8. Tobias Hankel

Most Criminal Minds fans know Tobias’ (James Van Der Beek) name because of what he did to Reid (Matthew Gray Gubler) and the brutal murder he used dogs to commit. He kidnapped and tortured the young agent, drugged him with Dilaudid, and even had him dig his own grave before Reid was able to get his hands on a gun.

Criminal Minds - Adam Nelson as Tommy Yates
CBS

7. Tommy Yates/The Womb Raider

Yates’ (Adam Nelson) body count exceeded 100, and he removed his victims’ reproductive organs after stabbing them. Yes, that was a horrific crime, but somehow what he put Rossi through was worse, at least from an audience point of view, because we know him: He made the profiler visit him every year on his birthday to receive the name and location of another one of his victims. (Rossi would eventually kill him after he escaped prison and added to his victim count.)

6. John Curtis/The Replicator

Curtis (Mark Hamil) copied previous serial killers and stalked and taunted the BAU throughout Season 8. Blaming Strauss (Jayne Atkinson) for the role she played in his stalled career, he killed the Section Chief and attempted to take out the team. (He failed.) However, he wasn’t as terrifying as some of the other threats they’ve faced over the years.

5. The Believers

It’s not the fact that they were a cult of serial killers, led by Benjamin David Merva (Michael Hogan), that made them particularly unnerving. It’s not even the fact that they abducted Reid and Garcia and were about to kill the former before the rest of the team found them. Instead, it’s the fact that an FBI agent (Karen David’s Mary Meadows) was a member and Garcia had to be willing to die when her life was threatened to make Reid surrender.

Criminal Minds - Keith Carradine as Frank Breitkopf

4. Frank Breitkopf

There was something so chilling about Frank’s (Keith Carradine) interactions with Gideon (Mandy Patinkin) and the fact that they had to let him go in “No Way Out” to save a bus of children he’d abducted.

Then in his return, he targeted and killed those important to Gideon, including a victim he’d rescued and his girlfriend. Will anyone forget Frank and his girlfriend Jane jumping in front of a train to their deaths? Or that it was Frank’s actions that ultimately led to Gideon’s resignation from the BAU?

3. Cat Adams

The fact that the network of hitmen existed was quite disturbing, but it was specifically a threat to Garcia (Kirsten Vangsness), because of her investigation, and later Reid, because one of them, Cat (Aubrey Plaza), blamed him for her imprisonment. Cat was responsible for framing Reid for murder and therefore the time he spent in prison himself.

C. Thomas Howell as George Foyet/The Reaper in Criminal Minds

2. George Foyet/The Reaper

Foyet (C. Thomas Howell) had quite the body count to his name even before first appearing in the Season 4 episode “Omnivore.” But it’s not the fact that he killed more than 30 people that puts him so high on this list.

Instead, it’s the horror and suffering he inflicted on Hotch (Thomas Gibson), from stabbing him nine times to making him listen as he killed his ex-wife and planned to do the same to his son.

Criminal Minds - Bodhi Elfman
CBS

1. Peter Lewis/Mr. Scratch

Lewis (Bodhi Elfman) began as just another UnSub the team was hunting, a man who used hallucinogens and hypnosis to force his victims to kill their loved ones. But he also targeted and psychologically tortured multiple members of the team, making him the worst one they’ve encountered (so far).

He got into Hotch’s head and made him see his team’s deaths, then he forced him and his son to enter witness protection for their safety. He brainwashed a man into believing he was Tara’s (Aisha Tyler) brother while holding the real Gabriel captive.

He lured the team into a trap that resulted in Walker’s (Damon Gupton) death and Prentiss’ abduction and torture.
