    Paul Bennett
"I'm Paul Bennett. Father on parole."
Played by: Mark Pellegrino

"Just making sure dear Dexter is dealing decently with his dead dad."

Rita's abusive, violent ex-husband and father of Astor and Cody.

  • Adaptational Heroism: Heroism is definitely too strong a word, but television Paul is at least a loving father while his book counterpart (who was The Ghost and thus received little characterization) was specifically stated to have violently abused Cody and Astor along with Rita.
  • Asshole Victim: To get him out of the picture without killing him, Dexter frames him for drug usage while on parole. Paul protests his innocence when he is sent back to prison, but no one buys it. He is eventually killed in a prison fight.
  • Attempted Rape: After Paul leaves prison, he arrives to his house and tries to rape Rita, but she is able to fight back.
  • Bitch in Sheep's Clothing: Tries to act nice and welcoming, but doesn't take long for him to get angry with Dexter and Rita.
  • Cassandra Truth: Tells Rita about Dexter being a bad guy. She doesn't believe him obviously.
  • Jerkass: He's a violent man and used to treat Rita very badly. The main reason why Rita idolizes Dexter as the perfect man is because she compares him to a Jerkass like Paul.
  • Mirror Character: With Dexter, occasionally. Both exhibit a harmless facade (which Dexter is better at maintaining) but have violent impulses. Both of them care for the children.
  • Mugging the Monster: Tries to intimidate Dexter. Doesn't work.
  • Would Hit a Girl: As to be expected from a violently abusive husband.

    Neil Perry
Played by: Sam Witwer

A computer analyst who is arrested as a likely suspect in the Ice Truck Killer case. He later turns out to be a fake, hungry for fame.

  • Big Bad Wannabe: In order to make a name for himself, he consciously obstructs a murder investigation by claiming to be the Ice Truck Killer.
  • Freudian Excuse: As a child, he was regularly abused by his mother but did not retaliate. Considering that he mutilated her corpse immediately following her death, it is apparent that his relationship with her was not beneficial to his psyche.

    Alfonso "Little Chino" Concepcion
Played by: Matt Willig

Alfonso "Little Chino" Concepcion was a very big member of a gang called the Twenty-Ninth Street Kings who uses a machete to kill any witness of his gang's crimes. For every kill he makes, he has a teardrop of blood tattooed on his arm. Because of his massive structure and build, Dexter Morgan views him as the perfect target following his depressive state after the killing of his brother, Brian Moser.

    Carlos Guerrero
Played by: Rudolf Martin

Carlos Guerrero is featured as a major antagonist for Sergeant James Doakes, one of the main characters for that season. Dexter Morgan originally investigates Guerrero but decides that his world is not one that he needs to participate in (he'd rather just stick to other killers). Regardless of that fact, Guerrero is still someone that deserves to be on Dexter's table.

  • Bad Boss: Unless something can actually be traced to him, he's calm as can be when one of his henchmen is arrested...but to keep them from talking, he's quick to have another assassin kill them. This shows that he's exactly what a drug kingpin on top of the world would be like...he's arrogant, thinks he's above the law and capture, and cares nothing for his subordinates.
  • The Don: He's this for his drug ring in Miami.
  • Even Evil Has Loved Ones: Like some drug lords, he does place his loyalty in family and especially his daughter who he cares for severely.

    Santos Jimenez
Played by: Tony Amendola

A violent drug dealer who also killed Dexter's mom. Dexter makes his end extra gruesome.

  • But for Me, It Was Tuesday: He has no idea who Dexter is when they meet. Justified, as Dexter was a young child when Santos killed his mother and he does remember Laura Moser when prompted.
  • Karmic Death: Killed in his drug cabin by the son of his victim with the weapon that killed said victim's mother.
  • Retired Monster: A violent drug dealer who still moves a little coke on the side.

  • Ate Her Gun: She commits suicide by sticking her gun into her mouth and blowing her brains out.
  • Broken Bird: She's consumed with guilt over killing Lundy and obsessed with earning her father's approval. By the time she dies, Christine has become a shuddering, teary-eyed wreck.
  • Daddy's Little Villain: Everything she does is for her father, Arthur. He would prefer is she didn't meddle, because she puts his cover in danger. He gets furious when she tells him she tries to protect him.
  • Driven to Suicide: With the police closing in and Arthur having abandoned her, she shoots herself.
  • Manipulative Bitch: She uses her sex appeal to seduce Quinn into divulging important details regarding police investigations in order to protect her father, Arthur Mitchell. She also gets a few hot news and exclusive articles.
  • Ms. Fanservice: She has plenty of nude moments and explicit sex scenes.
  • Nice Job Fixing It, Villain!: Her murder of Lundy and shooting of Debra put Dexter, and later Miami PD hot on Trinity's trail, leading to his death at Dexter's hands. Ironic that she killed Lundy to protect Arthur.
  • The Ugly Guy's Hot Daughter: Nobody guessed she could be the daughter of Arthur.
  • Smug Snake: She puts this on for her police interview, mocking Debra and staying impassive.
  • "Well Done, Daughter!" Girl: Towards Arthur, AKA The Trinity Killer. She protects because she wants his serial killer approval.
  • Yandere: For her father. She takes it very badly when he even slightly criticizes her.

    Johnny Rose & Nikki Wald AKA The Vacation Murderers
Played by: Alicia Lagano (Nikki Wald) / Unknown (Johnny Rose)

A pair of meth-addicts who began robbing and killing tourists.

  • Asshole Victim: Johnny Rose not only committed violent murders, he also cheated on his girlfriend who was helping him with them.
  • Ax-Crazy: When Nikki gets arrested, she's out of her mind on meth, hallucinating that Johnny is still alive and ranting about how they were going to go to Bermuda.

  • Bitch in Sheep's Clothing: She's friendly to Dexter during the house opening, but it's clear to both Dexter and the audience that this is just a façade.

  • Mirror Character: When researching her life, and speaking to her before he kills her, Dexter realizes that the main concern with her old life; being trapped by the demands of others, is the same problem he is facing. However, during the killing ritual, Dexter realizes despite this, he rather have his family than lose them.
  • Mugging the Monster: She finds out Dexter is investigating her and assumes he is a harmless lab geek in over his head, thinking she can kill him. Needless to say, she is very wrong.
  • Offing the Offspring: She murdered her young daughter.
  • The Sociopath: Manipulative and charming with no regard for anyone but herself. When Dexter asks her why she killed her husband and daughter in their own beds, she explains that it was so she could be free of care again.
  • Would Hurt a Child: She killed her own child who was still a very young girl.
  • Worthy Opponent: To Dexter. He really enjoys hunting her in a little cat-and-mouse game.

    Stan Liddy
"You fuck with the bull, you get the horn."
Played by: Peter Weller

  • The Alcoholic: Liddy drinks tequila heavily almost any time he appears onscreen, and at one point invites Quinn out for a beer... at 7:00 in the morning.
  • Asshole Victim: Dexter kills him partly out of self-defense, as Liddy is preparing to torture him to extract a confession.

Played by: Germaine De Leon

  • Death by Irony: Dexter drowns him at the same beach where Brother Sam had him baptized.

  • Tempting Fate: "I can't believe how well this worked out!"
  • Ungrateful Bastard: Brother Sam only tries to help him, and Nick shoots him for his trouble.

    Raymond "Ray" Speltzer
"You look strong. I like 'em when they're strong."
Played by: Matt Gerald

A groundskeeper at a cemetery who kills women and keeps their earrings as trophies. Likes to hunt his victims in some sort of a Saw-like maze using a bullhorned helmet before killing them.

  • Asshole Victim: Speltzer is a psychotic maniac who traps women in mazes and hunts and kills them. He's also an enormous Smug Snake who mocks Deb when she's unable to charge him and attends the funeral of his victim to mock her grieving relatives. Dexter killing him is what gets Deb to accept that what Dexter does is necessary.
  • Creepy Souvenir: He keeps the earrings of his victims.
  • Disposable Sex Worker: His usual victims are prostitutes, partly because they're easier to lure into his home but also because they disgust him as much as his mother did when she brought over customers.
  • Dumb Muscle: He's a steroid popping body builder strong enough and tough enough that it takes four cops to bring him down... but he's considerably lacking in the brains department compared to Dexter's previous adversaries (The Ice Truck Killer, Trinity, etc.).
    Dexter: Speltzer may have a lizard brain like me, but his shortcoming is he doesn't have much of a human brain.
  • Freudian Excuse: As a child, he was traumatized by the experience of having his mother bring "customers" home while she earned money as a prostitute. So, every time he invites a girl home and she complies, he is reminded of his mother.
  • Hunting the Most Dangerous Game: With a bullhorned helmet no less.
  • Smug Snake: He attends the funeral of his own victim.
  • Son of a Whore: His mother was a prostitute who brought men over while he was in another room. This fueled his rage to prostitutes in general.
  • Wicked Cultured: Has an affinity for certain aspects of Greek mythology.

    Clint McKay
"It's sink or swim, sonny-boy."
Played by: Jim Beaver

Hannah's cruel and abusive father.

  • Abusive Parents: He was quite abusive of Hannah. No wonder she ran away at an early age.
  • The Atoner: Subverted as he says he's trying to atone for his past mistakes, but really he's just after more money.
  • Bitch in Sheep's Clothing: Very polite and affable at the start until Hannah refuses to give him money.
  • Blackmail: What he tries against Hannah.
  • Dirty Coward: He shamelessly abuses his own daughter for purposes of extortion and/or for his own amusement. However, he pleads for his life when he realizes Dexter is about to kill him.
  • Dirty Old Man: He shamelessly leers over Jaime, making her uncomfortable.
  • The Gambling Addict: One of Hannah's earliest memories of him is how he left her in a hotel room for at least 3 days while going on a gambling binge. Additionally, the sole reason he tries to reconnect with Hannah in "The Dark....Whatever" is to obtain money to pay his gambling debts (presumably so he can repeat the cycle all over again).
  • The Sociopath: His "talents" as a con man are due in large part to his complete indifference to the well-being of those around him including his own daughter, Hannah, whom he routinely manipulates and abuses to get what he wants. Additionally, he has a pronounced lack of impulse control as evidenced when he almost immediately drops his kindly demeanor and explodes into a rage when Hannah expresses reluctance over giving him money. Furthermore, he shows a highly pronounced sadistic streak if his abusive treatment of Hannah as a child and undisguised ogling of Jaime is any indication.
  • We Hardly Knew Ye: He only appears in one episode before being dispatched by Dexter.

  • Even Evil Has Loved Ones: He's still in contact with his wife, who wears her wedding ring decades after he went to prison.
  • Greater-Scope Villain: If he hadn't had Laura Moser killed, Dexter wouldn't have grown up to be a serial killer and the entire show wouldn't have happened.
  • Small Role, Big Impact: Hector is debatably Dexter's most important kill in the series, following Santos Jimenez (who was directly responsible for Laura's death), though he killed her under coercion from Hector, making Hector the most urgent kill in the series, because of the trauma he inflicted on both Dexter and his brother Brian Moser's lives.
  • You Killed My Father: Dexter's life goes full circle when he finally avenged his mother.

    Miles Castner

However, he ultimately reveals himself to be a violently possessive egomaniac hellbent on dominating every aspect of her life.
