    Dexter Morgan 

Dexter Morgan

"I'm Dexter, and... I'm not sure what I am. I just know there's something dark in me."
Played by: Michael C. Hall

"I'm not the monster he wants me to be. So I'm neither man nor beast. I'm something new entirely, with my own set of rules. I'm Dexter."

The show's protagonist. Dexter was adopted into his foster-family as a three-year old after his mother was murdered in front of him. Growing up with bloodthirsty tendencies, Dexter was trained by his father to direct his urges to kill at those who "deserve it", and to never get caught. Works as a blood spatter analyst for Miami Metro PD.

  • Affably Evil: He actively cultivates a friendly persona. Bordering sometimes on Faux Affably Evil.
  • Adaptational Heroism: In the books, Dexter views Rita as more like a pet and he doesn't really care about anyone except for maybe Debra and children in general. In the TV series, he grows to love Rita and cares a great deal for the people around him.
  • Adorkable : When Hannah drops by and Dexter tries to fix his hair while looking at his reflection in a photo frame. Also a few examples when he's trying to fit in and getting it wrong, the bemused look on his face is charming.
  • Ambiguous Disorder: He's said to be sociopathic, but he is far too restrained and can calculate too well into the future to be one. He was never diagnosed as such, as he deliberately messed with the diagnosis under Harry's request which leaves us with yet inexplicable violent urges and lack of ability to socialise and feel empathy. Overall, the safest diagnosis for him is a psychopath. Not in the common Hollywood definition of the term, but in the actual clinical definition; antisocial behavior, diminished empathy and remorse, high self confidence, social assertiveness, fearlessness, poor impulse control, and disinhibited or bold behavior. Still, even that doesn't fit him entirely.
  • Ambiguously Evil: Zigzagged; he considers himself Necessarily Evil while in-universe opinions (and even out of universe) regarding his work as the BHB range from 'Byronic Hero' to 'Ax-Crazy and in it For the Evulz'. It should be noted that for him necessary evil doesn't mean "small evil in order to do great good." It means 'small evil in order to control myself so I don't do even greater evil.' Which is just according to what he says.
  • Animals Hate Him: Rita's neighbour has a dog that hates him utterly.
  • Anti-Hero (Nominal Hero): While Dexter may be the protagonist of the series, and his actions are mostly directed at those who could be considered morally worse than himself, he only does it because of his own urges to kill.
  • Anti-Villain (Type I or Type II): Despite being a serial killer, Dexter does have redeeming qualities and virtues that make him a character who can be rooted for and sympathized with. The Code of Harry and Dexter's personal inhibitions, such as being incapable of harming children or his family, are one of many things that ultimately assist in demonstrating that Dexter is not as monstrous as he thinks he is. And his traumatic experience as a child, which provoked his compulsion to kill, is an event that is shown to have deeply affected Dexter and continues to do so even years later.
  • Asexuality: Subverted. In the pilot, Dexter says, 'I don't understand sex. Not that I have anything against women, and I certainly have an appropriate sensibility about men, but when it comes to the actual act of sex, it's always just seemed so undignified.' Later on, it turns out he is pretty sexual, but he's aversive towards sex because somehow his partners get a glimpse of what he's really like. He sticks with Rita because somehow she doesn't.
  • Awesomeness by Analysis: He's a blood spatter analyst who can reconstruct a crime scene in seconds.
  • Badass: If there's a dirty cop, ex-special forces soldier, gigantic gangster, Nicaraguan death squad leader or fucking Jock Dexter can't kill, he hasn't met them and killed them yet.
  • Badass Baritone: Bordering on Evil Sounds Deep while he's enjoying his rituals.
  • Badass Bookworm: To the point he's almost a Genius Bruiser, capable of going toe to toe in a fight with the bulky Doakes.
    Doakes: Lab geek my ass!
  • Batman Gambit: He tells Oliver Saxon he will kill him with the pen on his desk when he comes to perform a GSR test on him. Oliver grabs the pen and stabs him with it, but misses and lodges it in his shoulder; Dexter seizes the opportunity to overpower him, grab the pen, and lodge it in his neck, thereby allowing Dexter to argue for self defence.
  • Battle Trophy: Dexter takes a blood sample from every killer he's killed. Until season 7, when he stops after Deb confronts him for it, and destroys them all.
  • Becoming the Mask: The fake life co-created with Harry as a cover to kill gradually becomes real.
  • Break Their Heart to Save Them: Dexter fakes his own death to leave Hannah's and Harrison's life for good, as he believes he will destroy their lives too if he stays with them.
  • But Not Too Gay: In the series premier, Dexter says, 'I don't have anything against women, and I certainly have an appropriate sensibility about men [...]' However, he never so much as checks another man out throughout the whole series. Then again, this could be chalked up to Early Installment Weirdness. Though this view relies on what one thinks an "appropriate sensibility about men" is.
  • Can't Stand Them, Can't Live Without Them: Dexter jokingly remarks "Can't live with her, can't kill her" about his sister Debra. He doesn't actually dislike her though, just hates the fact she inhibits his possibility of killing. He makes huge efforts to defend her.
  • Combat Pragmatist: When in doubt, if Dexter isn't able to murder his victim in his Kill Room, he will find ways to kill them. Best seen when he takes out Oliver Saxon, the Brain Surgeon with a fucking pen.
  • Consummate Liar: A given when one has to master a dual life.
  • Control Freak: He keeps everything tightly organized, and rarely trusts others to do things right. He does not react well when people interfere with his stuff, be it his computer or his shed or...anything, really.
  • Creature of Habit: He's obsessed with daily rituals and routines of his and other peoples.
  • Creepy Monotone: His inner monologue is smooth and constantly calm.
  • Creepy Souvenir: He collects blood samples from his victims. Deb made him stop doing so once she found out that he was the Bay Harbor Butcher.
  • Dark and Troubled Past: When he was three, his mother was murdered right in front of him.
  • Dating Catwoman: First with Lila (a pyromaniac Yandere), then with Hannah McKay (a Master Poisoner). He doesn't end up with either of them.
  • Deadpan Snarker: Mostly in his inner monologue, but in the present as well, quietly snarking to others.
    Doakes: "You trying to be smart?"
    Dexter: "Not 'trying', no."
  • Detective Mole: He uses his position within Miami Metro to manipulate the police.
  • Did I Just Say That Out Loud?: He blurts out that LaGuerta died because she 'wouldn't leave things alone' Angel.
  • Disposing of a Body: Wraps the bodies in plastics, hacks'em good and then drops'em to the bottom of the sea.
  • Does Not Like Guns: He prefers to kill with knives, since they leave less evidence behind.
  • Doom Magnet: By the end of the series, Dexter has killed over a hundred people and caused the deaths of many people around him, including relatively innocent people such as Doakes, Rita, Laguerta, and ultimately is forced to mercy kill Debra.
  • Even Evil Has Standards: Dexter kills only killers and pedophiles.
    • He brags of being a "very neat monster" and doesn't look too well on those who don't tidy their playground, whatever it may be.
    • He despises anyone who hurts kids in any shape or form.
    • When a copycat killer of the Bay Harbor Butcher shows up, he's very unhappy about it. He doesn't exactly consider himself a role model to be emulated, but someone who has to harness his dark urges into something productive.
    • He also doesn't like to tamper with evidence unless it's his own hide on the rope, and even then he half-heartedly does it. Makes you wonder why he went into forensics if he wasn't prepared to someday use the position to tamper with some incriminating evidence against himself.
  • Expy: Dexter is similar to Tim Dorsey's Serge A. Storms: both are south Florida-based serial killers who only target bad guys, with the first Serge novel Florida Roadkill published in 1999 and the first Dexter novel Darkly Dreaming Dexter published in 2001. Per Tim during his 2013 book tour for The Riptide Ultra-Glide, Showtime was even offered a Serge TV show two years before they were offered Dexter.
  • The Fettered: He has a "Code of Harry" that guides who he kills, how he kills and why he kills. It's purpose is to keep him on the "man" side of "man-monster".
  • Flanderization In the beginning of the series his social facade is actually believable, as intended with Harry's lessons in blending in. He smiles, cracks jokes, flirts and offers insightful comments, is only entirely clueless about some of the deeper emotional issues pertaining to relationships and makes up for his lack of empathy by being incredibly observant, an expert liar and thinking on his feet, and his inner monologue is mostly cynical comments, snarkery and exposition. By the third season he seems to have no idea how to act in any situation whatsoever, comes off as incredibly slow-witted in general conversation, and his inner monologue is 90% self-centered poetic imagery.
  • Foil: Dexter gets a few in the series.
    • Perhaps the most notable is Debra, his sister. Dexter is very much in control of his life and is also a serial killer. Debra's personal life is a constant mess, but she's a brilliant detective and believes in the strength of the legal process. Both of them also have amazing natural intuition, which helps them both track down serial killers.
    • The Ice Truck Killer, a.k.a. Rudy Cooper, a.k.a. Brian, his brother. Both have an instinctual need to kill and enjoy their respective rituals. However, Dexter is bound by his code and has loved ones he doesn't want to hurt, whilst Brian is Ax-Crazy and only cares about fulfilling his need.
    • Arthur Mitchell, the Trinity Killer. Like Brian, both Dexter and Trinity have a ritualistic need to kill that stems from a Freudian Excuse. They're also both family men with a wife and children to look after. The difference is Dexter actually cares about his family and treats them with respect, while Trinity is an Abusive Parent with control issues.
    • The Brain Surgeon, a.k.a. Oliver Saxon, a.k.a. Daniel Vogel. He is even viewed as mirroring the Ice Truck Killer in almost all of his tendencies, but his desire is to harm Dexter while Brian's was to be in Dexter's life and free him from the Code. In addition, as opposed to Brian, the Brain Surgeon shared Dexter's ultimate goal of living a normal life.
  • Freudian Excuse: Witnessing the murder of his mother and be left in the ensuing blood pool.
  • Happily Adopted: Finds a new and caring family, but his darkness can't be erased.
  • Heterosexual Life-Partners: With Batista. He's one of the few people Dexter genuinely likes.
  • Hired to Hunt Yourself: His hobby often collides with his work for the Miami PD, leading to a lot of evidence tampering and misdirection.
  • Hunting the Most Dangerous Game: His modus operandi is killing other killers.
  • I Just Want to Be Normal: Dexter often monologues that he wishes he could feel like everyone else, stripped of his own drives to slaughter. He even uses this to get closer to Rita after asking a couple about the secret of a successful relationship right before he kills them.
  • It's All My Fault: Dexter frequently believes he's the cause of all the horrible things people around him go through and struggles to stop it from happening. Debra defies it in the series finale, saying she's an adult who's responsible for her own choices, but she develops a blood clot during her operation that would not let her reason or even eat on her own. When the doctor says it would take a miracle for her to really recover, Dexter says he's never seen a miracle, implying that being saved in the ocean by a boat named 'Miracle'note  was not a miracle―it was a disaster.
  • Knife Nut: Has an aversion for guns so his evidence-free routine involves a knife, but he sometimes chooses a more exotic weapon - axe, chainsaw, hammer...
  • Lackof Empathy: He thinks he is this, and for the first two seasons, he's mostly right. However, come season three and beyond, Dexter begins to realize he truly does care about others around him, especially Debra and his family. And ultimately, his progress was all for nothing, as his sense of empathy and emotional development hinders his abilities to kill his targets, causing the death of Rita, the dissolution of his family, nearly kills him when he's facing Travis Marshall, and leads to Vogel being killed and Debra being shot. He is ultimately forced to abandon his son and girlfriend and ends the series a devastated shell, capable of feeling emotions and all the pain that comes with it.
  • Manipulative Bastard: He successfully plays the Miami Metro staff several times, such as leading them to believe Brian Moser killed himself or that Hector Estrada and Maria LaGuerta killed each other.
  • Mr. Fanservice: Particularly in season 2, Dexter is frequently shown half-naked and Michael C. Hall sure isn't bad looking...
  • Murder Is the Best Solution: His first thought when someone gets in his way is "can I kill them?"
  • Nice Job Breaking It, Hero: Several times, especially in later seasons when he begins to start breaking the code with some regularity by going after people who the police were about to catch, instead of people who were slipping through the cracks like he's supposed to. As a result of his bloodlust, his wife is killed by Trinity.
  • No One Could Survive That:
    • Travis Marshall makes that fatal mistake near the end of season 6.
    • Dexter somehow survives sailing into a violent storm in the series finale.
  • Not So Different: From Hector Estrada, the man who ordered the murder of his mother, of all people.
  • Papa Wolf: People who even mildly threaten his kids meet a very bad end. A paedophile that targets Astor, Lila West, Travis Marshall...all dead.
    • He's also this to others, as well. When Arthur Mitchell tried to strangle his son to death, Dexter responds by garrotting him and nearly stabbing him to death on the spot.
  • Pay Evil unto Evil: The whole premise behind the code isn't justice, it's to focus his own evil urges in a way that is 'productive', targeting only criminals that have escaped punishment.
  • Poetic Serial Killer: When particularly disgusted or angered by a killer, or when it's necessary, he kills them with a method that's relevant to their crime, such as bludgeoning Arthur Mitchell with a hammer, or drowning Nick at the same beach he had been baptized at by the man he killed, Brother Sam.
  • Principles Zealot: He knows without the Code he'd slip into the darkness completely and become like his brother.
  • Psychotic Smirk: Fantastic things are done with lighting to make Michael C. Hall look as much like Light Yagami as possible when he turns on the evil grin.
  • Serial-Killer Killer: His whole schtick is that he kills other killers. He isn't limited to serial killers, but he's certainly taken them out. Brian Moser, Miguel Prado, Arthur Mitchell, Walter Kenney, Travis Marshall, Raymond Speltzer...
  • The Sociopath: Zig-Zagged throughout the series. During the first two seasons, this trope is played straight with Dexter given his general portrayal as a completely self-absorbed individual who is only capable of feeling alive when killing. However, in Seasons 3-6, Dexter steadily becomes more conscious of the needs and feelings of those in his life and begins to take a personal interest in their well-being. However, throughout Season 7 and the first half of Season 8, the legitimacy of Dexter's newfound humanity is brought into doubt after he realizes that he kills others merely because he enjoys it and begins to suspect that his attachment towards others may be nothing more than a self-serving front for possessive feelings characteristic of all sociopaths. Nevertheless, by the end of the series, Dexter ultimately subverts this trope when he learns at a terrible cost that he has grown to value those in his life far more than his own bloodlust and happiness.
  • Sociopathic Hero: Particularly in the first two seasons, where Dexter is doing relatively 'heroic' things, but has yet to develop the burgeoning sense of empathy and emotions that would later define his Character Development.
  • Sympathetic Murderer: He only kills abominable people who deserve to die because they got away. His justice system is extremely solid. Plus he's a charming guy.
  • They Look Just Like Everyone Else: Polite, charming, good-looking, and he even works for the police. You'd never know he was a calculating serial killer-killer.
  • Trademark Favorite Food: Seems to have a fondness for steak. Pork sandwiches and bananas are his favourite "driving" food.
  • Übermensch: Dexter becomes this when he starts ignoring his "Dark Passenger" and the Code of Harry to start picking his own targets.
  • Underestimating Badassery: Many underestimate the lab geek.
  • Unreliable Narrator: Dexter often talks about how he doesn't have any emotions. While his emotions are definitely subdued, it's made pretty clear that he cares for the people close to him and have a conscience, that although quiet most of the time, still occasionally haunts him. He's pretty reliable regarding everything but himself.
  • Vigilante Man: Part of his trademark is that he only goes after other bad guys (with a few exceptions). He's explicitly referred to as this, when a comic book writer bases his work on him and makes him into a Batman/Punisher/Spawn hybrid called 'The Dark Defender'.
  • Villain Protagonist: At least during the final episodes of seasons 2 and 7. Season 2 has him going on to try and frame Doakes, while the end of season 7 has him trying to kill Laguerta.
  • Well-Intentioned Extremist: Double subverted. His methods certainly are extreme and his target selection ensures that he's probably a net positive force in the universe, but he doesn't do it to make the world a better place, he does it because he needs to. However, as time passes by, he begins to kill people for their moral reprehensibility, as his urges seem to lessen somewhat.
  • Woobie, Destroyer of Worlds: After witnessing his mother being murdered, he grew up with sociopathic tendencies.
  • Wouldn't Hurt a Child: Dexter is fond of children, finding them to be more interesting and easier to understand than adults, and he tends to drop his normally calm attitude around those of his victims that preys on them. He even broke his code of only killing murderers to get rid of a paedophile who was stalking Astor.
  • Wrong Genre Savvy: Dexter often projects his own experiences and motivations onto other killers and thus misinterprets their motivations and reactions. He expects the killer to play out one of the usual stereotypes and is blindsided when the killer actually does something completely different. This gets him in a lot of trouble and gets a lot of people killed.
  • Xanatos Speed Chess: He often has to work on his own crime scenes, and has to play merry hell with the chain of evidence.
  • Your Cheating Heart: He cheated on Rita with Lila in season two. However, they had a big fight and Dexter interpreted it as a break-up.

    Main Characters 

Debra Morgan

"You say anything more about my brother and I will kick your fucking nuts down your throat."
"Me in a dress. I feel like a transvestite."

Dexter's foul-mouthed, tomboyish foster-sister. Deb is a detective in Miami Metro's Homicide division. Debra believes she truly knew her father, but is in reality completely unaware of the secrets he kept'especially concerning Dexter (who she sees as a true brother). Inspired by their fathers' legendary police career, Debra joined the police and desperately yearned to become a Homicide Detective, which she achieves during the series.

  • 10-Minute Retirement: Season 8. She's not really cut out for the private sector.
  • Asskicking Equals Authority: After she's promoted to Maria's position as lieutenant.
  • Badass: Perfectly capable of kicking major amounts of ass, such as the most psychotic of the Fuentes brothers.
  • Badass in Distress: She was kidnapped by the Ice Truck Killer in the season 1 finale.
  • Born Detective: The only one in the department apart from Doakes. Dexter makes it very clear that he is mainly free because his sister has a "blind spot" on him.
  • Broken Bird: She's broken in-series at the hands of the Ice Truck Killer, and by getting shot and seeing her lover killed in series 4. This is lampshaded heavily in her therapy sessions in series 6. Being ignored by her father in favor of her adopted brother probably didn't help things. In series 7, she finds out Dexter's secret. She doesn't take it well.
  • Broken Pedestal: In season 7, Dexter's anchorage and high-concept gets broken for her after the reveal.
  • Cartwright Curse: Her love interests tend to either leave, die or turn out to be dicks.
  • The Chains of Commanding: Soons learns that with greater power comes greater and unpleasant responsability.
  • Cluster F-Bomb: Hoo boy. Deb really likes swearing, legendarily so. Most characters have at one point or another referred to her as a "potty-mouth" or in some way referred to her impressive swearing skills.
  • Cool Aunt: To Rita's kids after Dexter and Rita got married, and she absolutely adores little Harrison.
  • Cool Big Sis: She loves Dexter a lot. They are really close and she gets pissed whenever she feels he shuts her out, which is fairly often.
  • Defective Detective: A competent detective whose personal life is a wreck, when it exists.
  • Deuteragonist: She tends to have the second important plot after Dexter, usually solving the crime that connects to one of Dexter's victims
  • Dirty Cop: Though a more sympathetic example. In season 7 after finding out Dexter is the Bay Harbor Butcher. She does dirty things like hiding/manipulating evidence and then killing LaGuerta to protect Dexter.
  • Dirty Harriet: Made pretty fun in the book, noted at least twice that victims' relatives expect a Dirty Harry, not Legally Blonde.
  • Dropped A Bridge On Her: A particularly infuriating example; after she's shot by the Brain Surgeon, it's almost a given she'll bounce back, especially since this isn't the first time she's been shot. And then, random blood clot, and she's brain dead.
  • Fair Cop: She's absolutely hot and lots of her colleagues fancy her. Especially Masuka keeps mentioning she's hot and keeps hitting on her.
  • Foil:
    • To Dexter. Dexter is cool, calm, collected, and very much in control of his life. He's also secretly a serial killer. Deb is insecure and constantly losing control of her personal life. She's also a brilliant detective and has a strong faith in the legal system.
    • Takes a whole new slant in season 7 when she finds out Dexter's secret. An entire episode is spent discussing the pros and cons of Dexter's vigilantism to Debra's following the law to the letter.
      • She and La Guerta , as the only women in a predominantly-male workplace, act as foils to each other as well as to the men in the group. La Guerta was a good cop but is better at playing the politics she needs to climb the ranks. Deb is too honest and emotionally driven to politic very well, and ends up being La Guerta's Butt Monkey after the Fuentes case.
    • Deb is also a comedic version of a foil to Masuka's pervy jokes. Every time he hits on her, she one-ups him but neither takes the razzing seriously.
  • Genre Blind: In the novels, but even moreso in the television series. To the point where some viewers would block their ear-holes. Lampshaded in series 7 when she finds out Dexter is a serial killer.
    Debra: I am the worst fucking detective in the world.
  • Hope Spot: Gets one from Brian, her fiancee and future killer if it were up to him and hangs on to it in desperation, while he's not even trying that hard to pretend anymore. It bombs, of course.
  • "I Know You're in There Somewhere" Fight:
    • She loses this with Brian.
    • In series 7, this is her reason for not turning Dexter in after finding out his secret.
      Debra: I still believe that there is good in you.
  • Lady Swears A Lot: She hardly ever avoids swearing and filthy language. She justifies it by saying it's a cop mouth. Sometimes it's even adorable.
  • Love Makes You Evil: At the end of Season 7 she kills LaGuerta in order to protect Dexter. In Season 8 Vogel even comments that it was an act of selfless love.
  • Married to the Job: Increasingly so, as times goes by she finds herself with a bigger commitment to the job and without a stable relationship outside the one with Dexter.
  • Mercy Kill: In the series finale, Dexter unplugs her from her life support, as the doctor says she will never be able to reason or eat on her own, and probably not even breathe without life support, due to the blood clot she suffered.
  • Not Blood Siblings: In season 6, she realizes she's in love with Dexter. In season 7, she tells him during a fight. Later on Dexter gets her to check how she feels again and realise her close connection him was only natural and not that kind of love.
  • Not So Different: She chooses to let the "vigilantes" go in Season 5, and previously made very clear what her thoughts about the case were.
  • Office Romance: She starts sleeping with and falls in love with Agent Lundy, their task force leader in season 2. In season 5, she starts a casual relationship with her colleague Quinn. There is also the implication that she has dated coworkers in the past, and even as far back as season 1 there's subtext indicating she and Sgt Doakes might have romantic interest in each other.
  • Rank Up: Gradually promoted from Officer to Detective and Lieutenant.
  • Really Gets Around: She's quite the serial monogamist.
  • Real Women Don't Wear Dresses: As illustrated by her presiding quote up there. She's the tomboy girl to Rita's girly.
  • Secret Keeper: In Season 7 she finally learns the truth about her brother and helps him keep it a secret.
  • Sex for Solace: How her "relationship" with Quinn starts after Rita's death.
  • Shipper on Deck: For Dexter/Rita. She's the one that introduces them in the first place! In season 2, when Dexter was having an affair with Lila and Deb finds out, she calls him out on it and states that Rita was perfect for him, not that - as defined by Deb - "English titty vampire".
  • That Woman Is Dead: Says so after the events of season 7; she goes to the private sector and doesn't want anything to do with Dexter.
  • Thicker Than Water: Sticks her neck out for her brother time and again, despite not being blood related in the traditional sense.
  • Tomboyish Ponytail: Her usual hair style when she's not working in Vice Squad.
  • Took a Level in Jerkass: In Season 8, she outright hates Dexter and has become addicted to drugs and alcohol as a way to cope with killing LaGuerta, which she considers her Moral Event Horizon. Then, there is her killing El Sapo in a fit of rage.
  • The Unfavorite: Craved Harry's attention and envied Dexter for all the time that her father spent with him. She assumed the special relationship was due to favoritism, as the real reason was well hidden.

Harry Morgan

"Killing must serve a purpose. Otherwise, it's just plain murder."
Played by: James Remar

"Never underestimate the capacity of other people to let you down."

Adoptive father of Dexter and father of Deb, Harry Morgan is ten years deceased when the series begins. A renowned detective in his day, Morgan became frustrated at the perceived lack of justice in the system. Attempting to channel Dexter's sociopathy into a useful outlet - and to avoid him getting caught - he trains Dexter to become the perfect killer. Initially portrayed in flashbacks, he later manifests in Dexter's imagination, reminding Dexter what Harry taught him.

  • The Ace: He was a legend on the force from the seventies to the nineties. People still talk about him.
  • Broken Ace: He had issues with the injustice of the legal system, especially how some criminals manage to get away. It troubled him deeply and made him traumatize his kids. It ultimately drove him to decide that the best way to deal with his adoptive son's dark urges is to train him and turn him in serial killer who would hunt criminals.
  • Broken Pedestal: He's got a lot of darkness in him. Debra and Dexter saw him as a great father and the best cop there ever was, but both came to realize he was far from it.
  • Commander Contrarian: The Imaginary Friend version of Harry always seems to be against whatever Dexter's currently up to.
  • Dead Person Conversation: He frequently shows up to Dexter.
  • Dirty Cop: Like Deb does in season 7, he keeps Dexter's secret from the police. Also, there's the fact that he slept with his informant.
  • Do Wrong, Right: He teached Dexter how to be "a very neat monster" living by the code.
  • Driven to Suicide: Upon walking in on Dexter sawing up the body of a pimp he had been hunting and seeing that his training had Gone Horribly Right.
  • Really Gets Around: He liked to sleep with his female informants.
  • Scare 'Em Straight: He brings Dexter to a live execution to instill in him the danger of getting caught.
  • Your Cheating Heart: He cheated on his wife with Laura Moser and possibly with other attractive informants.

Ángel Batista

"Don't go down that emotion road, just go down on her. She'll be distracted."
Played by: David Zayas

Angelo "Ángel" Batista is a Detective in Miami Metro Police Department's Homicide Division. Batista works closely with Dexter during cases, often teaming up with him for his expert advice on serial killers, and considers himself Dexter's best friend. Batista is basically good-natured, with a dry sense of humor. He is also totally honest, at the request of his beloved father on his deathbed. Angel is also shown wearing a Trilby Hat almost all the time.

  • 10-Minute Retirement: Well on his way out in Season 7, the demise of LaGuerta makes him come back to the force.
  • Amicably Divorced: With Maria, following their Off-Screen Breakup between seasons 5 and 6.
  • Badass: Everytime he gets in a fight, he always has the upperhand. Can often knock people out in one punch, like he did with Quinn when he drunkenly kept harrassing Batista's sister.
  • A Father to His Men: A protective and fair lieutenant
  • Heterosexual Life-Partners: Seems to view Dexter as his and has a much greater claim to it than probably anyone else on the series. He's one of the few people Dexter really likes and wishes he could be like him.
  • Knight in Sour Armor: Gradually becomes this, especially in season 7 when he considers retiring.
  • Life of the Party: According to LaGuerta, at least. He never saves his money and likes to have a drink with friends all the time.
  • Made of Iron: He recovers very well from getting knifed by Brian Moser.
  • Married to the Job: In his own words, he's so focused on the work that he forgot to have a life.
  • My Sister Is Off-Limits!: Regarding his younger sister Jamie.
  • Nice Guy: Probably the nicest person in the show. He even supports Deb after she gets promoted above him.
  • Nice Hat: His trademark Trilby hat which he is almost never seen without.
  • No Good Deed Goes Unpunished: He is honest with his wife about cheating which leads to his divorce.
  • Overly Long Name: Ángel Juan Marcos Batista.
  • Passed Over Promotion: Several cops openly think he should have been the next lieutenant on account of his seniority, but Batista is content with the choice of Debra.
  • Stepford Smiler: In the first season. He and his wife were separated while he pretended that they are as happy and passionate as ever.

Vince Masuka

"Now you're dealing with science and science is one cold-hearted bitch with a fourteen inch strap-on."
Played by: CS Lee

"I got a reputation to live up to. I mean, if my show does not make people vomit and have an erection at the same time, then I've let my audience down."

Vince is the Miami Metro Police lead forensic investigator and works alongside Dexter in the lab and in crime scenes. He often cracks innuendo to the rest of the team, and harbors decidedly unrequited feelings for Debra. He is portrayed as obsessed with sex'the kinkier the better'and is not shy about propositioning every woman he meets.

  • Asian and Nerdy: Frequently referred to as lab-geek.
  • Bald of Awesome: He complete dismantles Ramon Prado with his memorable little lecture about the state of a crime scene. And of course, he's bald.
  • Bromantic Foil: In many ways he's the opposite of Dexter, romantically and otherwise; an extroverted, sleazy guy contrasted with the quieter, more polite lab geek with the stable relationship.
  • Bunny-Ears Lawyer: He might be an unbelievable sleaze, but Vince is also an extremely talented investigator, which might help explain why he hasn't been fired for conduct.
  • Chivalrous Pervert: Despite his dirty jokes and weird fetishes, Vince is a loyal friend who does adore women (he seems to actually go for tough women) and has even consoled Debra successfully.
  • Jerk with a Heart of Gold: He's a genuinely caring and loyal friend despite his attitude and wants their respect.
  • Kavorka Man: He actually does get women, and often they're quite gorgeous, despite how pathetic his game seems in the workplace.
  • Life of the Party: Proclaims to be this. Whether it's true or not is relatively unknown.
  • Lovable Sex Maniac: Probably why he hasn't been hit with sexual harassment complaints.
  • Vitriolic Best Buds: With just about everyone, but mostly Debra. They enjoy trading insults as she pretends to be overly offended by his flirting.

María LaGuerta

"The operative word is "boss". Show some respect."
Played by: Lauren Velez

Captain María LaGuerta is a tough, ambitious woman in command of the Homicide division who is not above bullying her subordinates and manipulating those around her in order to climb the law enforcement hierarchy. She and Isaak Sirko serve as the main antagonists in Season 7.

  • Adaptation Expansion: In comparison to her book counterpart, Maria's character gets a lot more expanded, specially since her book counterpart was killed by Brian and Dexter quite early.
  • Bad Boss: At first, she's tough but fair. As she sees her ambitions begin to fall apart, however, she resorts to increasingly desperate measures to keep her power. This includes throwing her employees under the bus and taking credit for cases.
  • Blackmail: She reaches the top by blackmailing Matthews with a prostitute's client book.
  • Big Bad: Of Season 7 along with Isaak Sirko. While initially beginning the story arc as a Hero Antagonist trying to clear Doakes's name, she ultimately becomes a Knight Templar willing to endanger others and bend the rule of law to the breaking point for the sake of incriminating Dexter. After Sirko's death,she eclipses him entirely as the story arc's preeminent Big Bad.
  • Never My Fault: One of her defining characteristics. She genuinely believes her misdeeds, failed plans, or cruel actions are not her fault.
  • Office Romance: It's revealed that Doakes and she were lovers when they were partners. She also dated Batista while being his direct superior.
  • Overly Long Name: María Esperanza del Alma LaGuerta.
  • Rabid Cop: After she Took a Level in Jerkass.
  • Rank Up: Starts the series as lieutenant, gets promoted to Captain in season 6 after blackmailing Matthews.
  • Spared by the Adaptation: In the original books, she is killed by Dexter and Brian, but in the series, she doesn't even get into the situation her book counterpart did. However, this is subverted in Season 7, when Debra kills her in the finale.

Joseph "Joey" Quinn

"This Dexter guy. First of all who the fuck is named Dexter? Did his parents know he was going to be a fucking egghead?"

Joseph "Joey" Quinn is a detective who transferred to the Homicide division after being in narcotics before Season 3. He has a bad habit of leaping to conclusions from first impressions of the crime scene, as well as becoming hostile towards anyone who tries to correct him. Quinn takes a liking to Debra Morgan but, like Doakes before him, mistrusts Dexter.

  • Badass: He's kicked a fair amount of ass, such as the very-deserving George Novikov.
  • Chick Magnet: Two hours undercover in a latino night club, six girls. One can understand why.
  • Cowboy Cop: And a Dirty Cop. He isn't massively corrupt, but does bend the rules when he thinks he can get away with it.
  • Despair Event Horizon: When Debra dumps him he falls into an escapable pit of despair.
  • Dirty Cop:
    • In season 4, he steals some money from a crime scene.
    • Also, when he was in narcotics, he took money from the Koshkas to look the other way. In season 7, he steals the proof against Isaak from the precint in exchange for Nadia's passport, but George double-crosses him and uses a recording of the deal to get him to keep helping the brotherhood. Then he kills George after he pushes him too far.
  • Good Is Not Nice: He's insensitive and takes offense easily, but at the end of the day he'll at least try to do the right thing.
  • Hero Antagonist: In Season 5, when he works to uncover who Dexter really is and unleashes Stan Liddy.
  • Love Makes You Dumb: Could be 'lust makes you dumb', since he has a habit of sleeping with people he shouldn't. For example, a reporter pumping him for information, a key witness in the Doomsday Murders, his boss, and a stripper working for the Russian mafia.
  • Rabid Cop: He really starts to lose his sense of morality after Debra break up with him.
  • Sex Equals Love: Quinn falls in love and proposes to Deb, while their relationship pretty much consisted of nothing more than sex. Deb even chews him out about the sudden proposal. In season 7, he falls quite quickly into a relationship with Nadia, too.
  • Suspiciously Similar Substitute: He's brought in to replace Doakes, and as of mid-season 5, is following the exact same path.
  • Took a Level in Jerkass: He went from Jerk with a Heart of Gold to just simply jerk in Season 6. List including bringing a stripper to his Ex's party, sleeping during work, sleeping with a potential witness, blaming others for his screw ups, drunkenly proposing to strippers, and telling Batista that he wants to have sex with his younger sister. How he isn't fired yet is a complete mystery. In season 7 he got better.

Rita Bennett

"I can't believe I found the one good, truly decent man left on the planet."
Played by: Julie Benz

"Deb must be a mess. I mean, falling for a serial killer?"

Dexter's girlfriend and later wife, who meets him through Deb. Rita is introduced as a damaged woman who received abuse from her ex-husband Paul, and is grateful for Dexter to give her support. Dexter also helps to look after her children, Astor and Cody. She is kind-hearted and nice to just about anyone, and Dexter ends up truly falling for her. She is horribly murdered by Arthur Mitchell in the season four finale.

  • Aborted Arc: Dexter discovers on the third season that she was married once, before marrying Paul. However, he decides to respect her privacy and the issue is never mentioned again.
  • Abusive Parents: Her mother was overly judgmental, as well as verbally and emotionally abusive.
  • Attempted Rape: After Paul leaves prison, he arrives to his house and tries to rape her, but she is able to fight back.
  • Batter Up: Uses a bat to defend herself from Paul.
  • The Beard: Unknowingly started off as this for Dexter so that he could blend into society, although he was asexual rather than gay. It no longer applies after he grows to genuinely care for her and the kids.
  • Betty and Veronica: For Dexter, she's a Betty to Lila's Veronica. She's the good and wholesome one.
  • Break the Cutie: Breaking of this particular Cutie happened mainly off-screen before the beginning. When her ex Paul appears, she starts breaking again. In season 2, she suffers mostly when her mother tries to control her life and causes her break-up with Dexter.
  • Broken Bird: She's a woman who was badly abused — severely beaten and repeatedly raped by her asshole of a husband. She was very fragile especially in season 1, and then kept getting better and stronger.
  • Calling the Old Man Out: She calls out her emotionally abusive mother.
  • Cosplay: Does one of Lara Croft in season 1.
  • Death by Adaptation: She's still alive in the book series.
  • Dramatic Irony: Just look at both her quotes! There's quite a bit like those in the first season.
  • Erotic Eating : With chocolate pudding, but apparently only when she's pregnant.
  • Hard-Drinking Party Girl : In her youth, Rita was a self-described "dress over the head party girl."
  • Hair of Gold, Heart of Gold: She's a sweet, wholesome and very feminine blond woman. She takes a very good care of her children and she's also a sweet and caring girlfriend.
  • Horrible Judge of Character: She first marries Paul, an abusive drug addict, and later Dexter, the Serial Killer. However, very few people see Dexter for who he really is, so she can't be faulted for that.
  • I Can Change My Beloved: Naively expresses this to Dexter during marriage counseling, indicating that she's failed to learn that this doesn't work even after multiple husbands.
  • Ignorance Is Bliss: She's at her happiest when she believes Dexter is the perfect man. She never finds out he's a killer, thankfully. (That is, unless Trinity said something to her.)
  • The Ingenue: She's a fairly naive woman, for a mother of three.
  • Kill the Cutie: In the TV-series only. She wasn't killed in the novels.
  • Morality Pet: To Dexter. He behaved wonderful to her for most of the time.
  • Nice Girl: She is very nice and very sweet to everybody to the point of being a pushover.
  • The Pollyanna: With all the crap that has happened in her life, she stays relatively upbeat.
  • Rape as Backstory: Her ex-husband was a crack addict who repeatedly beat and raped her.
  • Single Woman Seeks Good Man: Rita fell for Dexter because he was a kind man who loved kids, and was nothing like her ex.
  • Too Good for This Sinful Earth: She was sweet, kind, a little broken and a little naive but with nothing but good intentions...and she died needlessly.
  • Took A Level In Bad Ass:
    • Beating up Paul with a baseball bat after he tries to rape her following his release from prison.
    • Finally standing up to her overly judgmental, bordering on abusive, mother and kicking her out of Rita's house.

Tom Matthews

" haven't seen my true colors, Maria. But you're about to."
Played by: Geoff Pierson

"The great creature arose from the depths. Tokyo's that way, Maria."

A high-ranking Miami Metro PD police official and LaGuerta's immediate superior. He was an old friend of Harry Morgan, and therefore has a soft spot for Debra. He's also a political animal not unlike LaGuerta; however, he frequently clashes with her.

  • Da Chief: Mostly in season 1, but still remains this until LaGuerta topples him with a choice piece of blackmail. He returns in season 8.
  • Dirty Old Man: In secret, he uses prostitutes.
  • A Father to His Men: In contrast to Maria, he often appears friendly, professional and fatherly to the Miami Metro cops...except it's merely an act and he's more than willing to throw them under the bus to advance his own interests.
  • I Will Punish Your Friend for Your Failure: Batista pays the price when he needs to put pressure on LaGuerta.
  • Not So Different: From LaGuerta. He claims she's a Manipulative Bitch who'd do anything to hold on to her power, but he's not above using the same tactics as her to get what he wants.
  • The Bus Came Back: In season 7, he came back to the series to help a way.
  • What the Hell, Hero?: Hands them out frequently to LaGuerta, and sometimes to Debra, Batista or whoever else messes up.

Jamie Batista

Played by: Aimee Garcia

Angel's younger sister, who becomes Harrison's new nanny in the sixth season.

  • Ascended Extra: She was promoted to main character status on the eighth season.
  • The Cutie: She's downright adorable with a positive, bright smile.
  • Horrible Judge of Character: She states that Dexter "wouldn't kill a fly" and begins a relationship with Louis.
  • Ignorance Is Bliss: She's one of the happiest characters on the show, mostly because she isn't on the Police Force.
  • Long-Lost Relative: It's mentioned on one of their dinners together that Angel and Jamie did not grow up together, implying they didn't know about each other until they were older.
  • Magical Nanny: To Harrison, taking the role left by Sonya on the fifth season after she was Put on a Bus.
  • Ms. Fanservice: One episode has her take Harrison to the beach. While Hannah and Dexter are talking, the camara focuses on Jamie for a moment as she takes off her shirt, revealing a bikini top. Then Dexter quickly explains to Hannah that Jamie was Harrison's nanny. By season 8, she is seen fully nude in explicit sex scenes.
  • Nice Girl: She is a genuinely nice, cute girl who cares deeply about Harrison and even works late at night watching over him when Dexter has to leave, without hesitation.
  • Promoted to Opening Titles: For season 8.
  • Puppy-Dog Eyes: She has huge, expressive eyes that contribute to her role as The Cutie.
  • Shipper on Deck: Plays matchmaker for Dexter and Cassie.
  • Ship Tease: With Quinn in the season 7 finale. They share a drink at the restaurant opening and Quinn apologizes for his actions last season (he hits on her drunk and starts a g=fight with Angel and Louis at Deb's house inauguration). It's implied by this conversation Quinn might be interested in her. Six months later, they're dating in secret.
  • Your Cheating Heart: Louis cheated on her with a hooker while they were still going out. With the shirt she got him for his birthday still on.

James Doakes

"Surprise, motherfucker!"
Played by: Erik King

"Stop grinning like a fucking psycho and get back to work!"

James Doakes is a police detective with the rank of Sergeant serving as lead case investigator to Miami Metro PD's Homicide. Doakes had a killer's impulses which drove him to divorce his wife, confessing that if he had stayed with her he would have killed her. Holds a permanent grudge against Dexter, believing him to be suspicious and "creepy", which eventually leads to his downfall.

  • Badass: The second most badass character, after Dexter.
  • Cluster F-Bomb: Got to be about once a sentence.
  • Dark and Troubled Past: He worked for special ops before coming to Miami Metro, and he claims that he's pretty messed up because of this.
    • Evident in his obsession with exposing Dexter for what he really is.
  • Death by Adaptation: Killed by Lila in order to protect Dexter.
  • Disc One Final Boss: In Season 2. While quickly establishing himself as a major threat at the beginning of the story arc, Doakes' efforts to single-handedly incriminate Dexter end prematurely after the latter imprisons him within Jiminez's Cabin in " Resistance is Futile."
  • Elites Are More Glamorous: He was a member of the U.S. Army's special ops.
  • Foil: Ostensibly, he's the complete opposite of Dexter. Doakes is the abrasive Jerkass who is driven to anything to do good, while Dexter is the unassuming, kind lab geek who does everything to keep himself from doing greater evil.
  • Hair-Trigger Temper: Literally at times. It ends up harming him as his high level of on-the-job kills make it easier to see him as a killer.
  • Hero Antagonist: Until his death near the end of Season 2, he was Dexter's main foe on the good side.
  • Jerkass Has a Point: Dexter makes sure the point is buried under the obnoxiousness of a public antagonism.
  • Kill It with Fire: How he meets his demise.
  • The Lost Lenore: His relation with LaGuerta was brief, but she hasn't forgotten him and in season 7 she resumes his aborted Clear My Name quest.
  • Not So Different: Dexter notes that the only way Doakes could be so astute regarding him was that he had some of his own killing urges. In the book series, he even has his own Dark Passenger.
  • Only Sane Man: A rare example. He's the only one to notice something strange about Dexter, yet this only makes him looks as the total opposite of this trope in the eyes of everyone else.
  • Posthumous Character: A remarkable one time flashback reapparition in the season 7 finale, incidentally named after his Signature Line "Surprise, motherfucker"
  • Properly Paranoid: He's the only person who thinks Dexter is suspicious. He's oh-so right.
  • Sir Swears-a-Lot" Constantly throwing profanity at characters, especially Dexter
  • Sympathetic Inspector Antagonist: The sympathetic angle is usually cancelled by his abrasiveness, he would be an Inspector Javert if only Dexter were not actually guilty.

Played by: Keith Carradine

"I track killers. That's what I do. They tend to move around."

A high-ranking and illustrious FBI Special Agent recruited by Captain Thomas Matthews to lead the task force dedicated to identifying and arresting the Bay Harbor Butcher. He and Lila West serve as the main antagonists in Season 2.

  • Awesomeness by Analysis: He is not fooled by Dexter's letter full of fake hints and false leads, and quickly deduces it was fabricated by a person knowledgeable of police prodedures.

  • Famed In-Story: He's considered a 'Rock Star' among law enforcement.
  • FBI Agent: A well-regarded and famous one.
  • Hero Antagonist: Unlike the violently unstable Lila West who is a major antagonist AND villain in Season 2, Lundy is a thoroughly professional and ethical man. Nevertheless, he, like Lila, poses a preeminent threat to Dexter Morgan right up until the end of the second season.
  • May-December Romance: With the much younger Deb. He even points this out to her.
  • Married to the Job: His place is wherever there is a major crime to be solved. After a case is concluded he moves on.
  • Nice Guy: He's quite tactful, smiling and friendly. He also avoids confrontation when he doesn't see a benefit to it.
  • The Profiler: His job at the FBI. And he rocks at this game, breaking several extremely hard cases.
  • Put on a Bus: He leaves after the Bay Harbour Butcher case is solved at the end of season 2. The Bus Came Back: He returns in the fourth season as the cast investigates the Trinity Killer, who Lundy has been searching for his entire career.

Dr. Evelyn Vogel

Played by: Charlotte Rampling

"I believe that psychopaths are not a mistake of Nature, they're a gift. They're alpha wolves, who helped the human race survive long enough to become civilized. An indispensable demographic. Psychopathic traits can be found in the most successful CEOs, in the most effective politicians. Without psychopaths, Mankind wouldn't exist today."

An intelligent neuro-psychiatrist specializing in profiling psychopaths who acts as a consultant for various law enforcement agencies assisting in their investigations.

Vogel arrives in Miami to aide in the investigation of a serial killer known as The Brain Surgeon, helping profile and instruct Miami Metro Homicide as a consultant. She meets with Dexter Morgan here and in time reveals that she knows about the Code of Harry, as well as that Dexter is a psychopath and serial killer.

  • Admiring the Abomination: She's more than fascinated by psychopaths and praises them as a force of Nature.
  • Ambiguously Evil: She has some rather creepy mannerisms and believes that psychopaths are needed for humanity to develop, but she hasn't been anything but helpful. Even with the revelation of her new book about Dexter, she doesn't have any truly evil intentions.
  • The Man Behind the Man: She was the one who created Harry's code.
  • Parental Substitute: Treated as Dexter's mother in more than a symbolic sense.
    When Harry and I came up with the Code, he insisted that you only kill bad people, and I insisted that the first rule of the Code be, "Don't get caught."
  • The Profiler: She acts as a consultant for various law enforcement agencies, assisting in their investigations profiling serial killers.
  • Red Baron: She is referred and called the Psychopath Whisper.

  • The Social Darwinist: Views psychopaths as a necessary evil to cull mankind's weaknesses, as illustrated by her presiding quote up there.
  • Unscrupulous Hero: Despite being amoral and calculating, the Code she developed proved pivotal in helping Dexter control his bloodlust and eliminate far more dangerous and sinister serial murderers like the Ice Truck Killer, Trinity and Jordan Chase. Additionally, in order to protect Dexter from "unnecessary distractions", she does more than anyone else to rescue Debra from her suicidal downward spiral.
  • Well-Intentioned Extremist: She developed Dexter's Code primarily as a means to guide psychopaths like her son to advance the interests of society and humanity itself.

A transfer from Chicago who has an astounding solve rate and according to Deb, "had recommendations coming out the ass".

Louis Greene

Played by: Josh Cooke

A newly-hired tech-savvy intern.

  • Aborted Arc: In a case of Real Life Writes the Plot. Josh Cooke got a role in a major Broadway production, and therefore Louis' arc had to be cut short. See Dropped a Bridge On Him for the in-universe details.
  • Big Bad Wannabe: He wants to ruin Dexter's life, but he's pretty pathetic and is quickly ousted by more serious villains.
  • Broken Pedestal: He gets quite shaken when Dexter calls his serial killer simulation "tasteless".
  • Disproportionate Retribution:
    • After Dexter shuts down the premise of his game, Louis dedicates an unreasonable amount of effort to get back at Dexter, including mailing him the Ice Truck Killer hand, and cancelling all his credit cards.
    • He also did this to a former co-worker for equally petty reasons by putting a bunch of child pornography on his computer and getting him arrested for it.
  • Dropped a Bridge on Him: Season 6 hinted strongly that he knew Dexter was a serial killer and would become the next big threat to him. In Season 7, he's a nuisance to Dexter at best, he doesn't actually know about Dexter being a serial killer, and he is killed in the third episode by The Mafiya.
  • Evil Is Petty: His masterplan involves sinking Dexter's boat very gradually.
  • Fanboy: He's in total awe every time he watches Dexter decipher a crime scene.
  • Humiliation Conga: Fired, dumped and then murdered for being in the wrong place at the wrong time. Thats a humiliation parade.

  • Smug Snake: After Dexter threatens him, he still walks right into Miami Metro with a shit-eating smirk as if he's a king.
  • Techno Wizard: He basically does magic with computers whenever Masuka needs him to.
  • Your Cheating Heart: Paid for sex with a hooker while going out with Jamie. When Dexter sends Jamie a copy of the video, she breaks off the relationship.

  • Good Is Not Nice: He may be an asshole, but he's far from an evil character. He just wants his brother's killer to face justice.

Lt. Esme Pascal

  • Replacement Goldfish: Matthews replaces LaGuerta with her, mostly just to get the support of the Latino and African-American community.
  • Sanity Slippage: She steadily unravels as she begins to suspect her fiancee of cheating on her.
  • Tyrant Takes the Helm: She replaces LaGuerta, who's hardly a nice boss, but Pascal's lack of professionalism and incompetence make her brief reign a major inconvenience for Miami Metro.

  • Distracted by the Sexy: Everyone's reaction to her.
  • Hello, Nurse!: Everybody (Masuka, Quinn, Angel) has this reaction upon seeing her.
  • Hot Scientist: She was second in Masuka's interns, so she certainly has smarts. She's also ridiculously attractive, as is noted.
  • Ms. Fanservice: There are many loving shots of her ass, and she wears tight revealing clothes.
  • Nightmare Fetishist: Although it's possible this was only just an act in order to get pieces of evidence from famous cases to sell online.
  • Only in It for the Money: She gets herself fired after stealing from the evidence locker, selling an item from the Ice Truck Killer case online.
  • Put on a Bus: After Masuka finds out what she did (she broke the chain of custody and screwed him over), he fires her.

  • Out of Focus: In season 6 especially, continuing into season 7. It's a little odd considering Dexter is still the legal guardian.
  • Put on a Bus: After the Season 5 finale. She decides she wants to live with her paternal grandparents. The Bus Came Back in the seventh season when they visit Dexter for one episode.
  • The Stoner: In Season 7, Cody reveals that she's been doing drugs, although Astor claims she only does it to relieve her of the stress. She does admit that she knows they are bad.

  • Put on a Bus: Early in Season 7, Dexter is afraid for his life (specially after what happened with Travis last season), and with Isaak chasing after him, he decides to send Harrison to Orlando for some time with Astor and Cody. He returns soon, though.

  • 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.

Played By:

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.

Jeremy Downs

Played By: Mark L. Young

A young man who was an intended victim of Dexter.

Cassie Jollenston

Played By: Bethany Joy Lenz

  • 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.

Zach Hamilton

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.

  • 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.
  • Morality Pet: His mother for whom he genuinely seems to care about despite his bloodlust.

The daughter of Vince Masuka, who donated sperm in college, resulting in her conception. After the death of her mother, Niki tracks Vince down and the two meet for the first time.


Rudy Cooper/ Brian Moser AKA The Ice Truck Killer

"You can't be a killer and a hero. It doesn't work that way!"
Played by: Christian Camargo

The Big Bad and Dexter's main nemesis of the first season. The Ice Truck Killer murders prostitutes before placing them in a freezer (starting with an ice truck, hence the name), draining their blood and chopping them into pieces before displaying them for all to see. Through the entirety of the first season he leaves clues and hidden messages that he knows only Dexter will find at his crime scenes. He's eventually revealed to be Dexter's older brother, Brian Moser, who seeks to coerce Dexter into discarding all semblance of morality to embrace a life of bloodshed and depravity.

  • Ax-Crazy: The scarier part is that he represents what Dexter would be without the Code of Harry.
  • Badass: He kicks his brother's ass and evades the police seconds before they're able to catch him. All in the same scene.
  • Black and White Insanity: See the quote under his picture.
  • Big Bad: He's the main antagonist of season one, which revolves around the hunt for the Ice Truck Killer.
  • Bitch in Sheep's Clothing: He poses as Rudy Cooper, compassionate doctor and ardent boyfriend. In reality, he's a homicidal psychopath who doesn't give a shit about anyone but himself and Dexter, manipulating everyone—including Dexter—in order to bring his plan into fruition.
  • The Bus Came Back: For one episode, as Dexter's temporary Dark Passenger.
  • Cain and Abel: It isn't difficult to figure out which brother is which.
  • Chekhov's Gunman: For a while there, it seemed like he was just Debra's innocent prosthetist boyfriend.
  • Chekhov's Skill: By day, he makes prosthetic limbs. By night, he severs real limbs. His implicit basic medical training must help him cut so cleanly.
  • Consummate Liar: How else could he convince Debra that he was in love with her?
  • Criminal Mind Games: Plays these with Dexter for the entire season.
  • Dark and Troubled Past: From the murder of his mother, the separation from his brother, and his eventual institutionalization, Brian Moser had it rough. This is mostly revealed in Dexter's Troubled Backstory Flashback triggered by Brian in "Born Free," and the events proceeding.
  • Deadpan Snarker: Somewhat when he was alive, but he takes it Up to Eleven as Dexter's Dark Passenger.
  • Dead Person Impersonation: Stole the identity of Rudy Cooper, a plumber he killed in the late '90s.
  • Death by Adaptation: He survives in the books, but is killed by Dexter in the season one finale.
  • Even Evil Has Loved Ones: His impetus the entire season is to win over his long lost little brother.
  • Evil Counterpart: To Dexter Morgan more so than most characters. It comes with being brothers.
  • Fan Disservice: When he knocks out and later kills a hooker clad in nothing but his underwear.
  • Faux Affably Evil: The fact that he was so convincingly kind to even the most perceptive and naturally suspicious of individuals (i.e. Dexter, a Serial-Killer Killer) is a testament to his villainy.
    • He even sarcastically pretends to care about Debra's comfort while he has her duct-taped to a boat.
  • Fetish: He has an amputee fetish as a result of watching his mother get dismembered by drug lords.
  • Freudian Excuse: Witnessing the dismemberment of his mother in a shipping container and being left in the ensuing blood pool for two days.
    • And then being forcibly separated from his brother by Harry Morgan.
    • And THEN being committed to a mental institution until he was twenty-one.
  • Hidden Villain: The first of the series. In fact, the entire plot of the first season revolves around learning who he is, and the audience learns (before any character in the show) over halfway through the season.
  • Hoist by His Own Petard: Dexter slashes Brian's throat on the same inversion table Brian uses to drain his victims' blood.
    • Additionally, Dexter fools Brian into believing that a set of prosthetic limbs Brian made himself are really a sleeping Debra when he tries to kill her a second time. This allows Dexter to choke him from behind, leading to his death as described above.
  • Hope Spot: To Debra. Worst thing is, he's not even trying to pretend anymore. He's just fucking with her.
  • I Have You Now, My Pretty: His M.O. in general, but especially when he reveals his true nature to Debra and subsequently strangles her.
  • Killed Mid-Sentence: Dexter slices his throat while he's halfway through a small speech.
  • Kill the Ones You Love: Or pseudo-love. As far as the viewer knows, this is the first and only kill Dexter has ever cried over, as he killed the only person who fully embraced who he is.
  • Lack of Empathy: Dexter notes that he's "a killer without reason or regret."
  • Lean and Mean: He's the skinniest male adversary Dexter has ever faced, but he still beat him in a fight.
  • Luke, I Am Your Father: "Rudy Cooper" reveals himself as Brian Moser, Dexter's biological older brother.
  • Mad Artist: In Dexter's words, "The killer is an artist." Right before Brian strangles a hooker named Monique in bed, he also refers to his kills as his artwork.
  • Manipulative Bastard: He plays everyone, even Dexter, to fit into his plans. This includes being the doctor for one of his own victims and successfully getting Debra to fall in love with him.
  • Mean Character, Nice Actor: Christian Camargo is typically regarded as gracious and kind by those who have met him. A far cry from the Ice Truck Killer.
  • Mr. Fanservice: He's half-naked in almost all of his scenes with Debra.
  • No Celebrities Were Harmed: His modus operandi is primarily based off of Jack the Ripper, a serial killer in Britain near the dawn of the 20th century who brutally murdered female prostitutes and left their mutilated bodies on display for the public.
  • Rape Is a Special Kind of Evil: When the aforementioned Monique recalls her first sexual encounter with Brian, she mentions that he was very violent in bed. This makes him an anger-excitation (sadistic) rapist.
  • Red and Black and Evil All Over: He wears black pants and a red shirt in "Born Free." In the episode prior, he wears the same black pants and red shirt with a black blazer while he proposes to Debra and subsequently strangles her.
  • Self-Made Orphan: Killed his own father to expose one of Harry's lies to Dexter (and meet Dexter face-to-face for the first time in over thirty years).
  • Shadow Archetype: He represents what Dexter would be without Harry's Code.
  • Single Tear: Just before Dexter kills him.
  • Slashed Throat: How Dexter dispatches him.
  • Slasher Smile: Only once or twice, but when it happens, you know.
  • Stepford Smiler: Type C. Underneath all that deliberate sweetness and dorkiness is a psychopathic monster.
  • The Sociopath: Kills without remorse and without a code.
  • Villainous Cheekbones: This is pretty apparent throughout, but especially when he's doing something particularly disturbing.

Lila West/ Lila Tourney

"Dexter, meet Dexter. I'm gonna help the two of you get to know each other."
Played by: Jaime Murray

"You're going to tell me all your deepest, darkest secrets."

Dexter's temporary Love Interest in Season 2 who eventually joins Frank Lundy as one of the story arc's main antagonists. Lila become Dexter's sponsor when he enrols in NA meetings as his alibi. She learns of his "addiction" early on, finds a connection between herself and Dexter and later professes to be his soulmate. Dexter finally kills her after she murders Doakes "for him", believing that Dexter will run away with her, and tried to kill Astor and Cody when he goes back to Rita.

  • Bitch in Sheep's Clothing: She seems like a caring Narcotics Anonymous sponsor, right? Well, she might be, but she's also a psychotic pyromaniac.
  • Cute and Psycho: She's fun, kooky and extremely sexy...she's also unpredictable, obsessive and psychotic.
  • Eerie Pale-Skinned Brunette: She's an attractive woman, but her pale skin is a weird sight in sun-kissed Miami. Deb refers to her as Elvira or vampire, and lastly describes her as "pale as a fucking corpse". She really is a dangerous woman.
  • Evil Brit: Deb even comments on her being a 'English titty vampire' which is...not an inaccurate description.
  • Femme Fatale: She once killed an abusive boyfriend by burning his house down while he was in it. She initially didn't know he was in the house, but she doesn't seem to have many regrets about the outcome.
  • Kill the Ones You Love: Killed by Dexter when she spirals out of control.
  • Manic Pixie Dream Girl: A deliberate deconstruction of this trope. She has all the hallmarks of the crazy girl who encourages the buttoned-up hero to let his wild side out, but she's seriously and dangerously mentally disturbed and Dexter's wild side shouldn't be let any further off the hook than it usually is.
  • Monster Fangirl: She's still madly in love with Dexter when she finds out that he's secretly a Serial Killer, and even calls him a "poor creature" who just needs someone to understand him.
  • Ms. Fanservice: Besides being played by the very attractive Jaime Murray, she's frequently shown in sexy and nude scenes.
  • Not Evil, Just Misunderstood: Her opinion of Dexter's secret hobby.
  • Pyro Maniac: Fire is her weapon of choice, which she uses to burn her apartment, kill her ex-boyfriend and kill Doakes. It also works as an allusion to her wild, uncontrollable and destructive personality.
  • Raven Hair, Ivory Skin: She's a great beauty with pale skin and black hair. Angel absolutely admires her looks and calls her a pretty porcelain doll.
  • The Sociopath: Deconstructed. Dexter correctly identifies her as one of these despite Lila's claim that she's madly in love with Dexter. Her shallow affect and reduced empathy actually means that she's desperately tried to experience them somewhere. It's why she started counseling drug addicts in the first place and deludes herself into thinking that she and Dexter are soul mates.
  • Sophisticated as Hell: "Pardon my tits."
  • Yandere: She quickly becomes obsessed with Dexter, to the point of adoring him even after she finds out he's a notorious Serial Killer.

Miguel Prado

" I am the last person you wanna fuck with because I will fuck you BACK in ways you never even imagined!"
Played by: Jimmy Smits

"I'll do what I want to whom I want, to whoever I want! Count on it!"

Assistant District Attorney who befriends Dexter in season 3 after Dexter accidentally kills his brother in self defense, and Miguel later catches Dexter with blood on his hands after Dexter kills the man who Miguel believes is responsible for his brother's death. This leads to an odd partnership; however Miguel becomes increasingly unstable and eventually murders an innocent defense attorney, and Dexter is forced to kill him after realizing that Miguel has been manipulating him all along.

  • Abusive Parents: His father really messed up him and his brothers.
  • Amoral Attorney: Apparently he often tampered with evidence and did other shady things to get the results he wanted in court. Also became a serial killer.
  • Big Bad Friend: In Season 3, he turns out to be manipulating Dexter throughout pretending to be his friend. When his facade crumbles, he stops pretending.
  • Bitch in Sheep's Clothing: He cultivates the perception that he is the most level-headed and upstanding of his siblings in stark contrast to his hot-headed younger brother, Ramon. However, he is ultimately revealed to be a corrupt narcissist whose destructive wake is the primary cause of Ramon's Hair-Trigger Temper.
  • The Charmer: He's done so well politically as a result.
  • Consummate Liar: He is a wonderful monument of bullcrap.
  • Deceptive Disciple: Dexter teaches him the ways of murder, and he acts like a disciple of his. As it turns out, he planned to use Dexter's teachings for his own selfish purposes, behind Dexter's back.
  • Even Evil Has Loved Ones: He seems to genuinely care for his brothers and also values Dexter's friendship in his own narcissistic way. This is made apparent at the moment of his death when he expresses sincere anguish after Dexter admits to killing his younger brother, Oscar.
  • Expy: He bears more than a few similarities with another fictional handsome, idealistic law enforcement official of Latino ethnicity who grows increasingly corrupted by his lust for power.
  • Faux Affably Evil: Acts polite to a fault, but it's eventually revealed that it's all a facade, and he does it purely to manipulate people more easily.
  • He Who Fights Monsters: Starts out genuinely interested in killing criminals who escaped justice to give them what they deserve, but soon develops his own personal agenda and becomes no better than some of them...
  • Knight Templar: He is genuinely committed to cleaning up crime and corruption in Miami....even if it means subverting the legal process to those whom he believes to be guilty.
  • Manipulative Bastard: Gave Dexter his blood-stained shirt to gain his trust; this fools Dexter for almost an entire season before he discovers the stain is just animal blood.
  • Sanity Slippage: Most apparant when he goes utterly crazy at Dexter on the Miami Metro roof, ranting about doing whatever he wants.
  • Villainous Breakdown: He's got quite a temper, culminating in him blowing his top at Dexter on the Miami Metro roof.
  • Villain with Good Publicity: He's a beloved hero of Miami.
  • Well-Intentioned Extremist: At first, he wants to take out the trash like Dexter. He quickly graduates to killing his personal enemies.

Arthur Mitchell AKA The Trinity Killer

"It's already over....."
Played by: John Lithgow

"You're like a child......You dream of a heaven you'll never see."

The Big Bad of season 4, a mysterious, malevolent figure who kills in threes, referred to by Dexter as "the most successful serial killer to ever get away with it". Dexter tracks down Trinity only to find that Arthur has a family and hides within his community, just like Dexter himself and realizes that he may be able to learn a thing or two from him.

  • Bait the Dog: Despite being revealed as a serial killer early on in Season 4, he initially appears to be a loving husband and father who is otherwise tortured by a tragic past and a compulsive need to kill. At one point, Dexter even views him as a possible role model and decides to delay killing him long enough to learn how he has successfully led a double life for so long. However, as the season progresses, he is ultimately revealed to be a self-absorbed and unrepentantly cruel Straw Hypocrite who dominates every aspect of his family's lives through fear and brutality while viewing them little more as a cover for his true nature.
  • Badass Grandpa: Despite being at least 60 years old, Arthur's decades of experience as a killer coupled with his large size endow him with a substantial physical edge over most opponents. This is demonstrated when he subdues a strong individual like Dexter in a chokehold and overpowers his extremely athletic and muscular son, Jonah, with startling ease. Similarly, during the course of searching for Dexter in Miami, he brutally beats to death a far younger man with little more than his bare hands.
  • Berserker Tears: During the fourth kill in his cycle, beating a father of two to death.
  • Big Bad: Of Season 4 which revolves around the hunt for the Trinity Killer.
  • Bitch in Sheep's Clothing: See Bait the Dog above.
  • Broken Pedestal: Dexter initially views him as a role model for liking a dual life. However, in the latter half of the season, he comes to realize that Arthur is no different (if not worse) than the serial killer he has previously encountered and ultimately pays a heavy price for wasting several opportunities in the past to put him out of commission permanently.
  • Consummate Liar: An uncannily adept one whose skills surpass even Dexter. He reveals himself to be capable of effortlessly cultivating an affable and kindly public persona, lulling potential victims into a false sense of security, as well as feigning affection for his family whom he has little regard for (if any).
  • Control Freak: He has small rituals for literally every occasion, and he tends to get very unpleasant if they aren't followed to the letter.
  • Creature of Habit: To a much, much higher degree than Dexter. He is obsessed to a psychotic degree that all his habits and rituals are carried out the "right" way every time.
  • Death Seeker: Tries to kill himself, and minutes before being killed by Dexter, says that he had prayed to be stopped and sees his impending death as getting what he prayed for.
  • Domestic Abuser: Horribly abuses his family, both psychologically and physically.
  • Driven to Suicide: He tries to kill himself, but Dexter saves him.
  • Drop the Hammer: One of his kills is to murder a man with a hammer. Dexter kills him with a hammer as well.
  • Even Evil Has Standards: Don't call him a pedophile.
  • Evil Counterpart: To Dexter Morgan insofar as he represents everything Dexter fears becoming by leading a double life as a serial killer and family man.
  • Evil Mentor: At first, Dexter sees him as this when grappling how to apportion his time between tending to his family and satisfying his bloodlust. This changes when he finds out that Arthur keeps his family in line through fear.
  • Family Values Villain: In his public life, as a teacher, charity worker and church deacon. In actuality, a terrifying Domestic Abuser.
  • Freudian Excuse: He scared his sister in the shower as a child, causing her to fall and slice open an artery which kills her. His mother kills herself, and he's left alone with a drunken, abusive father who blames him for everything.
  • Interrupted Suicide: Tries to commit suicide but is saved by Dexter who wants to kill him instead.
  • It's All About Me: While his enduring guilt over causing his sister's death and his indignation over being called a pedophile indicate he is not entirely devoid of principles, it is ultimately made clear by the end of the season that he cares about no one but himself.
  • Knightof Cerebus: While the storyline was always dark, it was always counterbalanced by a darkly comic tone for the first three seasons as Dexter tried with mixed success to appear "normal" while moonlighting as a serial killer. However, with the onset of the Trinity Killer story arc, the dark comedy that characterized earlier seasons is increasingly diminished after Trinity destroys one of the biggest sources of emotional stability in Dexter's life and ultimately forces him to question whether someone with his bloodlust can ever live a happy life with others.
  • Lack of Empathy: Aside from grieving over his long-dead sister, he exhibits little (if any) genuine concern for the well-being of others including his own family whom he routinely abuses when they displease him and ultimately abandons.
  • Leitmotif: He's given "Introducing Trinity" and "Trinity Suite", both eerie, haunting pieces of music used to underscore Trinity's dark nature. It reappears in season 6 when the cops think they may have found him (in reality, Dexter killed him), but it is instead his son who did the murder.
  • Madness Mantra: "It's already over... it's already over..."
  • Manipulative Bastard: Due to decades of experience, he's become an expert at lulling his victims into a false sense of security before killing them. Similarly, he deludes his wife (and to a lesser extent) his daughter, Rebecca, into believing that he loves them when in fact he views them as little more than camouflauge for his true nature.
  • Mean Character, Nice Actor: One of the sweetest actors you'll ever meet and a dedicated author and singer for children playing a serial killer who buries kids alive.
  • Narcissist: A "malignant" example (i.e: one who displays both sociopathic and sadistic characteristics) . While perpetually cold and abusive to his family, he secretly wallows in self-pity over memories of his unhappy childhood and actively seeks to cancel them out by fostering a respectable public image as an upstanding family man and "community hero" . Additionally, he is extremely conceited given that he treats all those who don't meet his excessively high standards of meticulousness with contempt and derives smug satisfaction from his "success" as a serial killer (as evidenced when he smirks and even chuckles over photos of his victims at Miami Metro). By the end of the "Trinity Killer" story arc, the sheer extent of his self-centeredness and Lackof Empathy is made glaringly apparent when he robs his wife and children and leaves them at the mercy of federal authorities while he makes his getaway.
  • No Celebrities Were Harmed: His character is loosely based on John Wayne Gacy, a respectable construction entrepreneur who was widely renowned for his image as a family man and pillar of community service prior to being exposed as a serial killer and rapist who buried his victims beneath his home's crawl space.
  • Nonindicative Name: Is called the Trinity killer for his pattern of killing in threes, but he actually kills in fours.
  • Not So Different: Played with. Much of season 4 is Dexter wondering how different he really is from Arthur, and if he'll end up like him in his old age.
  • Sanity Slippage: After successfully getting away with hundreds of murders over many decades, it seems he's finally starting to crack under the strain of covering his tracks while simultaneously maintaining his public persona as a "community hero". When Dexter meets up, he's suicidal and begins blurting out his horrible past to complete strangers.
  • Self-Made Orphan: At some point after his mother's suicide, he killed his father with a hammer.
  • Shadow Archetype: Of Dexter. He is a very good picture of what Dexter can become if he allows himself to be completely overtaken by his habits and obsession with rituals.
  • Theme Serial Killer: He kills in fours, choosing victims who represent his family members in the order they died: a young boy, symbolizing the death of his own innocence; his sister, killed in the shower; his mother, throwing herself from a great height; his father, bludgeoned to death.

The "Brain Surgeon"

Click here to see "The Brain Surgeon" 
Oliver Saxon(AKA Daniel Vogel)
Played by: Darri Ingolfsson

"You have a lot more to lose than I do. Cute little son, your sister....a girlfriend.....All very lovely and all very easy to remove from your life."

  • Big Bad: Of the final season. His targeting of Dr. Evelyn Vogel along with Dexter and his loved ones serves as the story arc's primary source of conflict.
  • Bitch in Sheep's Clothing: His image is that of a handsome, charming young bachelor who is a productive and upstanding member of society. In reality, he is brutal and sadistic Serial Killer with a highly unpleasant personality. In addition to being insufferably vain and egotistical, he displays an extremely twisted sense of humor as can be seen when he jokes about how he murdered his mother.
  • Cain and Abel: Killed his younger brother Richard at the age of 14.
  • Chekhov's Gunman: Turns out that the boyfriend to Dexter's next door neighbor is actually the final season's Big Bad.
  • Consummate Liar: One far superior to Dexter Morgan. His skills for deception and faking emotions are among the best seen in the series.
  • Creature of Habit: He plays Mama Cass's "Make Your Own Kind of Music" during all of his kills. It is later revealed that he played the same song whenever he visited the King's Bay Cafe while he was a child..
  • Dead Person Impersonation: Uses the identity of one of the children he killed.
  • Dogged Nice Guy: Based on the times she met him, Jamie considered him to be this due to his repeated attempts to persuade her friend, Cassie, into going to the Bahamas with him after dating for only a few weeks. Subverted when he is confirmed to be the Brain Surgeon as well as Cassie's murderer.
  • Enfant Terrible: He murdered his first victim at the age of 12.
  • Evil Counterpart: To Dexter Morgan more so than any other character encountered in the series. Both characters are bloodthirsty serial killers who are at their peak in terms of physical prowess and sensory acuity (unlike the experienced but aged Arthur Mitchell). Additionally, unlike most of the series' antagonists, the "Brain Surgeon" is at least just as skilled and experienced a killer as Dexter given the ease with which he outmaneuvers the latter on several occasions. Moreover, unlike Brian Moser, he (like Dexter) aspires to settle down and lead a "normal" existence on his own terms as evidenced by his long line of fatal attempts to establish long-term intimate relationships . Thus, he represents what Dexter could be without being held back by a Code or emotional attachments.
  • Final Boss: The final serial killer Dexter plans on killing in the series so he can retire and start a new life with Hannah and Harrison in Argentina.
  • Go Out Witha Smile: If this image serves as any indication, then he was happy about it.
  • Green-Eyed Monster: Of all the Seven Deadly Sins, envy is his most defining personality trait.
  • Hero Killer: Of all the series' major antagonists, the Brain Surgeon is ultimately responsible for the deaths of more people close to Dexter than any other character. During the latter half of the season, he murders Dexter's protegé, Zach Hamilton, as well as his "spiritual mother", Evelyn Vogel. Finally, towards the end of the series, he ultimately places Deborah in a vegetative state after grievously wounding her (thereby setting in motion a chain of events that leads to her death.)
  • Hidden Villain: The Brain Surgeon's identity is kept secret until the ninth episode of the season.
  • Hope Spot: After being presumed dead for two episodes, the Surgeon returns at the end of "Are We There Yet?"
  • "I Am" Song: He adopts Mama Cass's " Make Your Own Kind of Music" as this. Initially, it appears that he is fond of the song because it reminds him of happier times he spent with his mother, Dr. Evelyn Vogel. However, considering that he later brutally murders Dr. Vogel without hesitation or remorse, it is more likely that the lyrics appeal to his own grandiosity and nihilistic worldview.
    "Nobody can tell ya/ there's only one song worth singing.
    They may try and sell ya/because it hangs them up to see someone like you.
    But you've gotta make your own kind of music/ Sing your own special song.
    Make your own kind of music / even if nobody else sings along."
  • Lack of Empathy:He shows no remorse for murdering his victims including his own brother, Richard. Likewise, he reveals that the sole reason for his desire to reconnect with his mother, Dr. Vogel, is so she can help him become a more efficient serial killer. Upon realizing that Dr. Vogel intends to hand him over to Dexter, he brutally murders her without hesitation. After the fact, he shows sadistic amusement over her death and smugly admits he found killing her to be a highly refreshing experience.
  • Leitmotif: After his identity is revealed, the Brain Surgeon's subsequent appearances are often accompanied by music rendered most distinguishable by an eerie, hollow ringing which reflect his complete lack of normal human emotions such as empathy and remorse along with how dangerously unpredictable he is as a result.
  • Matricide: He kills his mother, Dr Vogel.
  • Never My Fault: When confronting his mother about having him institutionalized, she explains that he left her with no other choice after he murdered his younger brother, Richard. Without skipping a beat, he pins Richard's death squarely on her.
    Saxon: "THAT WAS YOUR FAULT!! You ignored me! All you ever cared about was Richard!
  • A Pupil of Mine Until He Turned to Evil: Dr. Vogel believes the Brain Surgeon to be an old patient of hers. Ultimately it turns out to be her son.
  • Pretty Boy: Probably one of the most androgynous adversaries Dexter has ever encountered in addition to being one of the most evil. See image. As mentioned above, many fans of the series have half-jokingly referred to him as a doppelganger of Ryan Gosling.
  • Psychopathic Manchild: Type C. Despite appearing to be a well-adjusted young man on the surface, his emotional maturity remains stunted at a very childlike level given that he clings to the same petty grudges and possessive attitudes that drove him to murder his brother, Richard, when he was only 14. In "Goodbye Miami", he angrily confront his mother, Dr. Vogel, for providing Dexter with maternal attention and affection that is "owed" to him alone.
    Saxon:"Don't make the same mistake you did with Richard. Choose right this time. Choose me."
  • Stepford Smiler: Type C. Case-in-point.
  • Theme Serial Killer: As the name suggests, the Brain Surgeon cuts into victims' skulls and takes out the part of the brain that produces empathy.
  • The Sociopath: The vast majority of the final season revolves around Dexter pondering whether he is genuinely a psychopath incapable of experiencing love and forming meaningful relationships with those around him. Due to the fact that he is a clinically diagnosed psychopath, the Brain Surgeon unknowingly ends up convincing Dexter that he is NOT one by committing acts of depravity which leave the latter shocked and disgusted.
  • The Unfavorite: Resentful towards his brother and mother for what he perceived as a lack of attention.
  • Tongue Trauma: In the series finale, he forces a man to take him to the hospital where Debra is at gunpoint, then cuts off his tongue to make sure he doesn't talk. Since his victim can still write, this seems to be an act of mere horrific sadism.

Alfonso "Little Chino" Concepcion

Played by: Matthew Willig

  • Authentication by Newspaper: Blatantly uses this to create an alibi.
  • Beard of Evil: A thin goatee.
  • Badass: He's the largest and most physically dangerous killer Dexter has ever faced and works as a hitman for the Miami gangs. His massive size even allowed to escape from Dexter's restraints once, prompting another capture later on.
  • The Brute: He's the chief enforcer for a Hispanic gang. While he's not as dumb as his size would indicate his value to them stems largely from his strength and willingness to commti violent acts.
  • Cut Himself Shaving: The excuse he gives Doakes for his wound caused by Dexter.
  • Deadpan Snarker: Snarks at the police, knowing they don't have evidence on him.
  • But for Me, It Was Tuesday: Inverted. He makes a point to mention to never have killed a kid like the one in one of the photos Dexter shows him, Dexter points out the kid was still one of his victims because he ruined his life by killing his mother. (Not too mention when Dexter caught him he was about to brutally murder a kid for snitching.)

  • Small Name, Big Ego: He views himself as a sinister mastermind destined for fame when in fact he's little more than an unscrupulous poseur (albeit a violently unstable one)

  • Offing the Offspring: She murdered her young daughter.

  • Badass: His extensive steroid usage makes him one of the most formidable physical adversaries Dexter faces in the series in addition to Little Chino and Isaak Sirko.
  • 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 (Brian Moser, Trinity, Jordan Chase, etc.).
    "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.

"It's sink or swim, sonny-boy."

  • Blackmail: What he tries against Hannah.
  • Domestic Abuser: He was quite abusive of Hannah. No wonder she ran away at an early age.

  • Dirty Old Man: He shamelessly leers over Jaime, making her uncomfortable.
  • Faux Affably Evil: Very polite and affable at the start until Hannah refuses to give him money.
  • 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.

    Barrel Girl Gang 

Jordan Chase AKA Eugene Greer

Played by: Jonny Lee Miller

"It's time to tap into your primal selves and seize the power of instinct. We're gonna cast off those shackles that bind us to jobs we hate, people we don't love, lives that aren't worth living. We are going to... Take It!"

A charismatic and popular motivational speaker, known for his 'Take It!' approach to life. He's also a demented sociopath and ringleader of the Barrel Girl Gang.

  • Big Bad: Of Season 5. His cult's brutal rape and torture of Lumen ultimately sets in motion the conflict underlying the story arc.
  • Catch Phrase: "Tick, tick, tick. That's the sound of your life running out."
  • Control Freak: He must absolutely keep control of a situation at all times, and he freaks out pretty viciously when anything goes wrong.
  • Devil in Plain Sight: One hundred times more evil and famous than Dexter.
  • Enfante Terrible: If Emily Birch's story serves as any indication, Chase's depravity and grandiose sense of entitlement cannot be traced to any Dark and Troubled Past or Startof Darkness. Rather, even as a child, Chase seems to have disdained social interaction in general let alone any level of emotional intimacy. It was only when he experienced the thrill of manipulating others to do his bidding that he went from being an egocentric introvert into a charismatic Control Freak.
  • Faux Affably Evil: His public image is that of an extremely charismatic and polite self-help guru who is genuinely committed to turning his clients' lives around for the better. In reality, he is a sociopathic megalomaniac who uses his program as a means to completely dominate other people's lives for his own gratification.
  • Formerly Fat: Dexter tries to taunt him over his fatness. Jordan merely remarks that he is proud of that phase since he managed to come out of it and lose so much weight and become so successful.
  • Freudian Excuse: Downplayed; it's vaguely hinted that his actions have something to do with him being overweight as a kid, but it's oddly never brought up again.
  • From Nobody to Nightmare: He was just a fat kid at a summer camp who others felt sorry for. Fast-forward and he's a rich, popular motivational speaker with a side project in kidnapping, rape, torture and murder.
  • Go Out with a Smile: Or more like cackling after his facade has crumbled completely.
  • Hates Being Touched: Chase is portrayed as being averse to emotional or physical intimacy of any kind. When Emily Birch places her hand on his, he coldly disregards this sign of affection by irritably pulling his hand away. Similarly, rather than touch his victims himself, he manipulates others to do it for his own voyeuristic gratification.
  • It's All About Me: As a consummate megalomaniac, he views himself as a god deserving of unwavering praise and obedience from others without returning any of their loyalty.
  • Karmic Death: Stabbed by the woman he victimized and tortured, in the place where he did it.
  • Kickthe Dog: As an adolescent, he organized the gang-rape of a young camp counselor named Emily Birch whose only crime was trying to befriend him because she thought he seemed lonely. By the time he has become an adult, he is revealed to have completely brainwashed her since then and reduced her to being a slave for his ego.
  • Lackof Empathy: Despite clearly deriving amusement from dominating others' lives, Jordan shows no signs of emotional attachment or gratitude towards his "friends" regardless of their affection or loyalty towards him. This is most clearly evidenced by his relationship with his right-hand man, Cole, whose unwavering devotion he repays with barely concealed contempt and annoyance. Additionally, when the Miami P.D. begins to close in on his cult's activities, he doesn't show the slightest trace of hesitation or remorse when sacrificing his followers to facilitate his getaway.
  • Manipulative Bastard: Jordan is one of the uber-examples in the entire series. He controls an entire group of men since they were children, reduces a former rape victim into becoming a virtual slave, and manipulates Lumen's movements.
  • Meaningful Rename: The site of the first time he manipulated the Gang into raping a woman, where he developed his Take It philosophy? Camp River Jordan. We don't find this out till the season finale, when he drives past the camp's entrance sign... and then past an old Case backhoe*
  • No Celebrities Were Harmed: Chase's character is an amalgam of many famous cult leaders throughout history who attracted countless followers through appeals of self-empowerment and carpe diem. His megalomaniacal and deranged personality is based primarily on Aleister Crowley, a self-proclaimed sorcerer who indoctrinated his "disciples" to discard all their inhibitions while performing sacrifices and sadomasochistic rituals in order to discover their "True Will."
  • Poisonous Friend: Without his influence, the others (with the possible exception of Cole) probably wouldn't have gone on to become rapist superfriends. Of course, this doesn't mean they're any less monstrous. Not to mention that Jordan doesn't seem to care about any of them, being perfectly willing to sell them out to save himself. More than likely, he retains their company solely to derive gratification from wielding total control over their lives and being a figure of unquestioned idolization.
  • Rousing Speech: He's made a career out of rousing speeches.
  • Sharp-Dressed Man: Always extremely well-dressed as befitting a man of his self-assigned importance.
  • The Sociopath: A high-functioning case yet one of the more textbook examples seen in the series. (See Enfante Terrible, It's All About Me, and Lackof Empathy above).
  • Start of Darkness: Emily Birch recounts this. She tells Lumen about how he convinced the other members to gang-rape her, and describes momentarily seeing a 'look' on his face...and goes on the say it's the same look he has all the time as an adult.
  • Strange Minds Think Alike: Has the creepy and funny habit of finishing Dexter's mental sentances.
  • Villainous Breakdown: When he gets angry and kills Emily Birch with a fireplace poker.
  • Villain with Good Publicity: He's a well-known public figure and motivational speaker. Subverted in a realistic way, where he has legions of fans but it's clear he isn't well-thought of by most normal people. Still, they hardly think he's evil, just another run-of-the-mill motivators.

Cole Harmon

Played by: Chris Vance

The loyal head of security for Jordan Chase.

  • Badass: He's well-trained and extremely dangerous, posing a great threat to Dexter. As such, he's the most physically powerful of the group, having had a background in the marines.
  • Cold-Blooded Torture: It was his fetish when hurting Lumen.
  • Defiant to the End: He spits insults at Dexter and Lumen when they try to interrogate him.
  • The Dragon: He's Jordan's most trusted bodyguard.
  • Sharp-Dressed Man: Lumen nicknamed him 'Suit-And-Tie' since he carefully folded his clothes before raping her.
  • Undying Loyalty: Even though Jordan doesn't seem to like him much, he's crazily loyal to the guy. He almost seems to worship him, considering the fact he has framed pictures of Chase in his hotel room.

Boyd Fowler

Played by: Sean Hatosy

The 'cleaner' for the Barrel Girl Gang, he works in dead animal pick-up and is responsible for disposing of the gang's victims.

  • Nice Hat: Always sports a baseball cap.
  • Not-So-Harmless Villain: Dexter thinks he's just another slide-in-waiting, but Boyd thwarts him and causes plenty of trouble before and after his death.
  • Smarter Than You Look: Dexter mistakes him for a poorly-educated dead animal scooper, but he's actually quite cunning and observant.

Dan Mendell AKA "Dan the Dentist"

Played by: Sean O'Bryan

A dentist and scout for the group.

  • Alliterative Name: Not actually, but once it's revealed he's a dentist, Dexter, Lumen, and Debra all call him "Dan the Dentist."
  • Country Matters: Calls Lumen this. It gets his neck broken.
  • Depraved Dentist: He was a dentist in his everyday life.
  • Go Out with a Smile: Realizing he's about to die, Dan smirks at Lumen and taunts her, saying the others will get her.
  • Honey Trap: His role in the group... a little odd, since he's a schlubby middle-aged guy.
  • Neck Snap: Courtesy of Dexter, after he called Lumen a cunt.

Alex Tilden

"I-I never wanted to do any of it!"
Played by: Scott Grimes

A banker and weak-willed flunky of Jordan Chase.

  • Karmic Death: Murdered by one of his victims.
  • Nervous Wreck: He's constantly terrified that he'll be caught.
  • Unwitting Pawn: In the end, this was all he amounted to as far as Jordan was concerned.
  • We Hardly Knew Ye: His appearance is very brief, since he only turns up in person when Lumen and Dexter shorten the list.

Emily Birch

Played by: Angela Bettis

The first victim of Jordan Chase and the rest of the group. She's been kept alive by Jordan, living a solitary, damaged existence while still manipulated by Jordan.

  • The Alcoholic: She has a history of drunk driving.
  • Broken Bird: She lives alone, drunk and submissive and eager to please Jordan.
  • Rape as Backstory: She was gang-raped at Jordan's command when she was a camp counsellor.

    The Doomsday Killers 

Travis Marshall

"I am the Alpha and the Omega. I am the Beginning and the End."
Played by: Colin Hanks

"You're not going anywhere until you've repented for your sins."

A student of Professor James Gellar and his serial killer protege. It's later revealed that he has a Split Personality and Gellar has been in his mind the entire time, representing his 'Dark Passenger'.

  • Anti-Villain: Played with and ultimately subverted. At first, he merely appears to be a weak-willed individual who is being pressured by his former professor, James Gellar, into performing ritualistic sacrifices under the belief they are demanded by God. However, Gellar is ultimately revealed to be a product of Travis's subconscious embodying narcissistic and violent personality traits exhibited by him since childhood.
  • Ax-Crazy: May not be the most evil Dexter villain, but is definitely the most insane.
  • Bastard Understudy: Played straight at first, when he seems to be doing the bidding of Gellar. Eventually it's revealed that he was solo the whole time.
  • Big Bad: The main antagonist of season 6.
  • Cain and Abel: He killed his sister, though he was under the delusion that 'Gellar' had done it.
  • Heel-Face Turn: After an encounter with Dexter forces him to realize that Gellar is manipulating him, he begins having doubts. After an episode of trying to deal with his conscience, he makes the turn and frees the woman who would have been their next victim.
    • And then things went bad for him. Though he promises to help Dexter kill Gellar as a result.
    • But then he goes back to "serving" Gellar, or at least his interpretation of him.
  • Insane Troll Logic: Travis has to face the fact that Gellar had been Dead All Along: Gellar reminds him how he tried convincing him that they were supposed to be the Two Witnesses, then stabbed him with that sword he stole to show him he won't die; Travis said he didn't die, but he did, and Travis pinned the theft on Gellar. Then he denies he did it, and somehow concludes that 'it was the False Prophet’ (that is, Dexter) who did it. Then he completely embraces his role as the killer in his insane plan.
  • Knight Templar: His desire to purify what he sees as a thoroughly corrupt and vile world drives him to commit a series of brutal ritualistic murders that he hopes will bring about the Apocalypse.
  • Lack of Empathy: As said in his psych evaluation file.
  • Minion with an F in Evil: Subverted. It turns out he's not even a minion.
  • No Celebrities Were Harmed: David Berkowitz (a.k.a. "Son of Sam"), and Charles Manson. Travis resembles Berkowitz in the first half of the season, when he believes that he is being compelled to commit others by orders from God Himself. In the second half of the season, he begins to more closely resemble Manson after embracing his Dark Passenger as a product of his own twisted psyche and makes the transition from a reluctant killer to a megalomaniacal fanatic who gathers a small cult of "disciples" to assist him in his murderous crusade to bring about the apocalypse.
  • Pet the Dog: He genuinely loves his sister. Too bad his other personality doesn't much care for her.
  • Sanity Slippage: Not that he was all there to begin with.
  • The Sociopath: Lampshaded by his psych evaluation. However, this trope is subverted by his depiction in earlier episodes where his good side exhibits visible discomfort over the torture of another human being and desperately attempts to protect his sister from his Dark Passenger embodied by Professor Gellar. Consequently, his delusions of grandeur along with the manipulative behavior seem far more consistent with narcissistic personality disorder.
  • Split Personality: He has an alternate personality in the form of his 'Dark Passenger'.
  • Tomato in the Mirror: As Travis learns in the season's tenth episode, it isn't Gellar who's been doing the killings...
  • Well-Intentioned Extremist: He wants to end the world because of how corrupt it is. When he tells Gellar he wants out, Gellar responds by telling him about horrific murders and the like to talk him back in.

Professor James Gellar

"Is that what you want, Travis? To hurt me? You see how I suffer for your sins!"
"We were given free will for a reason, Travis."

A Professor of Religious Studies believed to be the dominant Doomsday Killer. He is later revealed to have been Dead All Along, murdered by his student Travis and kept in a freezer below an abandoned church. However, he continues to play a role in the Sixth Season as the personification of Travis Marshall's Dark Passenger.

  • Dead All Along: Revealed as such in 'Get Gellar'.
  • Dirty Old Man: Had a habit of sleeping with younger women.
  • Evil Counterpart: To Dexter's own ghost guide, Harry. He takes a more active role than Harry, though.
  • Evil Mentor: To Travis, whom he encourages and disciplines.
  • Evil Teacher: His basis was Travis' Professor of Religious Studies.
  • Faux Affably Evil: He's easy-spoken and gives Travis the illusion of freedom, but kills frequently and brutally.
  • Four Eyes, Zero Soul: He wears a pair of thick-rimmed glasses and no ethics.
  • The Heartless: As Travis Marshall's "Dark Passenger", he is the distilled form of Travis's more violent and megalomaniacal character traits. However, in 'Ricochet Rabbit', this malevolent "Gellar personality" is reabsorbed into Travis's consciousness.
  • Knight Templar: He seems to be this, but an episode had a teacher assistant of his reveal that he just likes to stir up trouble, so whether he really believes it or not is up in the air.
  • Manipulative Bastard: He harms himself when Travis doesn't follow orders, to better emotionally manipulate him.
  • The Mentor: To Travis when he was at college.
  • No Celebrities Were Harmed: His characters is based on American bible prophecy "experts" like Tim Lehaye.
  • Omnicidal Maniac: He hopes to bring about the end of days by following a series of rituals.
  • Posthumous Character: Travis kills him prior to season 6.
  • Split Personality: He's a separate personality manufactured by Travis's subconscious in order to cope with the guilt of murdering the real Gellar.

A high-ranking member of the Ukrainian Mob who comes to Miami to survey his business interests there and avenge the loss of one of his most loyal subordinates. He and Marie LaGuerta serve as the principal antagonists in Season 7.

  • Affably Evil: Incredibly polite and charming most of the time. Steers towards Faux Affably Evil when he starts to rack up the body count, as when he politely threatens to drill a guy's eyes in and then kills him anyway or rams a screwdriver inside a guy's eye while soothing him.

  • The Sociopath: At first he gives off this impression, killing with no hesitation or remorse and relating a horrible story about almost killing his piano teacher as a child. Ultimately subverted: everything he does, he does out of love, grief and a sense of personal guilt.
  • Tragic Villain: Towards the last two episodes, when he's revealed as a lonely, closeted man who's lost the love of his life and is hunted by his own people.
  • Worthy Opponent: Isaak and Dexter slowly gain a growing respect for each other, acknowledging the other as having very formidable skills.

  • Kick the Dog: Shoots Isaak in the stomach and is about to shoot him in the head when he stops and goes away electing him to suffer and die slowly from bleeding out.
  • No-Holds-Barred Beatdown: Quinn finally snaps and beats the ever loving shit out of him.
  • Pragmatic Villainy: Opposes Isaak's vendetta against Dexter because it's bad for business, as it would bring even more attention from the law.
  • Slimeball: He's horribly sleazy, making his strippers sleep with him.
