Played By: Mark L Young

A young man who was an intended victim of Dexter.

    Tony Tucci

An initial suspect and later almost-victim of the Ice Truck Killer.

  • Chuck Cunningham Syndrome: Disappears from the series without even a ripple, to the point where you could wonder whether the Ice Truck Killer finally finished him off after all and no one noticed.
  • Nice Guy: Despite being held for days and mutilated, he's friendly, upbeat, extremely affable and even apologizes to Deb and Doakes for not being able to remember more. Even then, he goes the extra length to recall a very traumatic memory just to help them.

    Anton Briggs
Played by: David Ramsey

A criminal informant who develops a romantic interest in Debra.

    Ellen Wolf
Played by: Anne Ramsey

A defense attorney and Miguel Prado's main rival.

  • Amoral Attorney: Subverted. She's not as straight-up charming as Miguel, but she has the integrity and morals that Miguel makes such a show of pretending to have. Then again, she's gotten off a number of scumbags who went off and killed again, so she has blood on her hands.
  • Asshole Victim: Whether she was principled or greedy is beside the point. She was thoroughly rude and unpleasant, and most viewers were not sad to see her go.

  • Jerk with a Heart of Gold: That said, she's a good person at heart and wants her clients to have fair trials.
  • Mrs. Robinson: She flirts heavily with a young bartender.
  • Sacrificial Lion: Miguel killing a principled character underscores that he means business.

  • Stepford Smiler: Like the rest of Arthur's family, he played the role of a happy family. He's the first to give up on it and rip his dad a new one. It would have likely ended in his death if Dexter wasn't there.
  • Two First Names: Either "Jonah" or "Mitchell" can be used as a first name.

  • Flat Character: He has absolutely no character whatsoever other than providing an obstacle for Rita and Dexter's relationship. And not even a big obstacle.

    • When she fatally stabs Jordan Chase, she exclaims "This is for everyone you've ever hurt, even Emily."

  • Broken Bird: She's traumatised after undergoing a horrific gang-rape and torture.
  • But Now I Must Go: Her departure. She says she's done with her revenge and cannot continue living with Dexter when her darkness is gone.
  • Combat Pragmatist: When you're a slight women with no combat training, you have to be pragmatic.

  • Hair of Gold, Heart of Gold: Before she was turn into an angel of revenge, she was just an angel.
  • Knife Nut: "Lookit those!" Dexter buys her one, and it's like a boyfriend buying his g-friend jewellery or a box of chocolate.
  • Meaningful Name: Lumen is connected with light. The word lumen is also associated with anatomy, in particular the space within the arteries and veins through which blood flows; it becomes especially meaningful with her last name.
  • Nervous Wreck: Her initial reaction after she's freed by Dexter. Then, she decides to take revenge.
  • Outlaw Couple: Lampshaded by Masuka in 5x11, who compares her and Dexter to Bonnie and Clyde. This does not sit well with Dexter.

  • Two First Names: Either "Wayne" or "Randall" can be used as a first name.

    Sal Price
Played by: Santiago Cabrera

"It's not in my nature to keep quiet about anything."

A True Crime fiction writer doing a follow-up to his earlier book about the killings by Wayne Randall.

  • Going for the Big Scoop: Played with, he is smart enough to avoid the usual methods of Hannah McKay, but he bites the dust anyway.
  • Good Is Not Nice: He isn't above engaging in bribery in order to expose those who have fallen through the cracks of the Miami justice system.

    Hannah McKay
"Sometimes a life has to be taken. There's no need to dress it up."

A woman who went on a killing spree with her boyfriend as a young girl, before gaining immunity after it was discovered he kept her in line with fear. This was later revealed to be a lie, with Dexter and Debra finding out she took an active role and tends to poison her problems away.

  • Abusive Parents: Her father almost drowned her as a child to make her 'sink or swim'. He's gotten no better, fully ready to send her to prison just to gain a slight benefit for himself.
  • All Girls Want Bad Boys: She has a thing for dangerous men. First Wayne Randall, and then Dexter.
  • Bitch in Sheep's Clothing: To the point that it's hard to tell how many of her sweet scenes are genuine or just manipulation.

  • Dating Catwoman: Hooks up with Dexter, much to Debra's chagrin.

  • I Did What I Had to Do: Her reason for killing a man who molested her.
  • It's All About Me: Isn't afraid to kill anyone who gets in her way, though she claims that she doesn't enjoy killing and she only does it when she thinks it's necessary (addressed below).
  • Karma Houdini: Played with. She dodged being punished for her actions, but as soon as she did she learned Dexter was dead. Of course, it turns out in the next scene he's just faking it, but she will probably never know.
  • Master Poisoner: She has killed at least 3 people with poison without leaving any traceable evidence.
  • Morality Pet: To the point that Dexter's love for her helps him let go of his homicidal urges in the last season.

Played By: Sam Underwood

The son of Ed Hamilton, a rich "friend" of the Miami Metro Police Department. A young budding Serial Killer, he killed a woman named Norma Rivera in an attempt to stop his father's affairs, which were ultimately hurting his own mother. Troubled by the continuing urges, Dexter Morgan takes Zach under his wing and begins teaching him the Code of Harry in hopes that he can provide the necessary lessons that can make Zach like he is, and prevent him from being caught.

  • Abusive Parents: A unique example in the form of his father, Ed Hamilton. While Ed spoils his son rotten with the best luxuries money can buy, he is also emotionally distant and implied to be abusive towards Zach's mother.
  • The Apprentice: Dexter teaches him the Code of Harry so he can be a "neat monster" too.
  • Anti-Hero: A nominal example given that he begins follows Dexter's lead by murdering serial killers in order to contain his sadistic urges. However, the Brain Surgeon kills him before he can fully internalize the Code of Harry.
  • Bitch in Sheep's Clothing: His image as a handsome, charming young man serves as a convenient disguise for his true nature as a bloodthirsty Serial Killer in the making. Partially subverted in later episodes when he is revealed to be little more than a less disciplined version of Dexter Morgan given that he genuinely loves his mother and looks up to Dexter much the same way that Dexter himself once looked up to Harry.
  • Creepy Souvenir: He takes photographs of his victims.
  • Cruel and Unusual Death: The Brain Surgeon uses a bonesaw to cut into his cranium while he is still alive.
  • Idle Rich: The fact that his father is filthy rich gives him a lot of free time to pursue his... "hobbies".
  • Lonely Rich Kid: Ultimately revealed to be this in "This Little Piggy". This is one of the primary reasons that Dexter decides to take him on as an apprentice instead of killing him.
  • Not So Different: From Dexter. He also has murderous impulses.

    Jacob Elway

A former Miami Metro detective who now owns his own private investigation company. Deb ends up working for him after quitting Miami Metro.

  • Fake Guest Star: Appears in every episode of the final season, and accomplishes quite a bit more than expected. He even manages to get his own story arc toward the end of the season.
  • Jerkass: By the end of the season, he's blows off Debra and basically smug about catching Hannah McKay.
  • Reasonable Authority Figure: Tolerates Deb's unprofessionalism partly out of concern for her and because she does get results.

  • Waking Up Elsewhere: In the series finale and fate in the show, after Hannah drugged him.
  • "Well Done, Son!" Guy: He had a very tense relationship with his father; he was expected to go into the family business, and he rebelled by going into law enforcement.

    Cassie Jollenston
Played By: Bethany Joy Lenz

A former finance executive who moves in next to Dexter Morgan looking for a quieter life.

  • All Girls Want Bad Boys: She was greatly fascinated in Dexter, finding the "unavailable, mysterious guys" the most appealing to her.
  • Girl Next Door: Literally, as in she moves in next door to Dexter. However it's subverted in the sense that "average normal wholesome girl" is not compatible with Dexter.
  • Sacrificial Lamb: A sweet girl who quickly falls victim of the Brain Surgeon.
  • We Hardly Knew Ye: Exits the story after just a few episodes.
