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'...to 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.
- 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.

"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.
- 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.
- Jumping Off the Slippery Slope: During Season 7, goes from grudgingly aiding and abetting Dexter to killing LaGuerta when Dexter is cornered in the finale.
- 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.

"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.
- Imaginary Friend: Most of his appearances (when they aren't flashbacks) are as this, to his son Dexter.
- The Mentor: To Dexter when he was alive. He's the Harry in "Code of Harry".
- My God, What Have I Done?: Seeing his son to bring home his kill... yeah, that can't be pretty. It made him violently sick and drove him to suicide.
- Pay Evil unto Evil: Part of his motive for training Dexter, especially after his Arch-Enemy, a drug-pushing cop-killer, gets Off on a Technicality.
- 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.
Played by: David ZayasAngelo "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.
- Beware the Nice Ones: He's a nice guy, but he's got a mean punch.
- Big Brother Instinct: For his little sister, Jamie. And Debra.
- 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.
- Working with the Ex: Until season 7, he works for his ex-wife Maria LaGuerta.
- Your Cheating Heart: Why his marriage collapsed.
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.

- 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.

- Knight Templar: In Season 7, she becomes James Doakes reincarnated.

- Working with the Ex: With Doakes and Batista. She's their boss, too.
Joseph "Joey" Quinn
Played by: Desmond HarringtonJoseph "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.

- 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.

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.
- Idiot Hero: Prone to Love Makes You Dumb related mistakes.
- Jerkass: Mildly at first, but after Debra broke up with him in season 6 he becomes aggressive, crude, unreliable and very petty.
- 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.

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.

- 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.

- 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.)

- 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.

- Jerkass Has a Point: Dexter makes sure the point is buried under the obnoxiousness of a public antagonism.

- 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.

"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."
- Admiring the Abomination: She's more than fascinated by psychopaths and praises them as a force of Nature.

Additionally, in order to protect Dexter from "unnecessary distractions", she does more than anyone else to rescue Debra from her suicidal downward spiral.

Played by: Josh CookeA newly-hired tech-savvy intern.

- 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.

- 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.

- 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.

- Cute and Psycho: She's fun, kooky and extremely sexy...she's also unpredictable, obsessive and psychotic.

- Not Evil, Just Misunderstood: Her opinion of Dexter's secret hobby.

- The Sociopath: Deconstructed. Dexter correctly identifies her as one of these despite Lila's claim that she's madly in love with Dexter.

- 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.

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"
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.

- 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.

- 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.

- Kick the Dog: A lot, anything that have to do with Hannah.

- Only in It for the Money: The entire reason he seeks out Hannah is to get cash from her; he's spent a long time making money off her 'fame'.

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.

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.
Played by: Chris VanceThe loyal head of security for Jordan Chase.

Played by: Scott GrimesA banker and weak-willed flunky of Jordan Chase.
- Ain't Too Proud to Beg: He begs and cries for his life.

- Dirty Coward: He panicks at the first sign of trouble, instantly calling Jordan after being interviewed by Deb and Quinn.
- 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.

- The Alcoholic: She has a history of drunk driving.

The Doomsday Killers
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.

- 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.

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.
