Played by: Uncredited (season 1), Alain Moussi (season 1), Maxim Savarias (season 1), Iain Glen (season 2)
Billionaire playboy by day, dark protector of Gotham City by night. Dick's former partner before breaking off away from the sidekick mantle.
- Adaptation Dye-Job: Iain Glen is/was a natural blond, in contrast to the dark brunette/jet black hair of Bruce in the comics and most adaptations. This change, however, makes him similar to the Adam West version of the character.
- Adaptational Jerkass:
- Over the years, Batman has become more and more driven in his crusade and brutal towards criminals, so Dick leaves him over this. He's disgusted at what his mentor has become and is afraid of becoming just like him. Trigon uses this against Dick in the first season finale, when he projects a dream where Batman kills all of the Rogues Gallery for the death of Commissioner Gordon.
- Initially seems to be averted when Bruce finally appears in Season 2 and he and Dick reconcile, implying Dick might have been exaggerating a bit about this particular flaw, but ultimately Played Straight by Season 3, where it's shown that Bruce has brushed off Alfred, Jim Gordon, and now Jason Todd's deaths without remorse for their loss, and is immediately trying to recruit another Robin so soon after.
- Age Lift: Taking cues from the prologue of Batman Beyond, he is played by an actor in his late fifties. Given that Dick is nearly thirty, this actually makes sense.
- Alternate Self: Many amongst The Multiverse:
- Ambiguous Situation: Was it really Bruce who lured Rachel, Kory, Donna, and Dawn to Elko Diner and encouraged them to reunite the Titans in "E.L._.O"? Kory speculates that it was Rachel's powers acting up, but we don't know for sure.
- Ascended Extra: Downplayed. He went from being The Ghost in season 1 to being a reoccurring supporting character in the second season.
- Batman Grabs a Gun: Or rather, a crowbar. And beats the Joker to death with it.
- Broken Ace: An extremely wealthy man who is also widely regarded as the World's Best Warrior is also a man traumatized by his parents' murder since he was a child who ever since has been struggling to keep himself from being consumed by his demons. He eventually becomes so broken he kills the Joker in retaliation for Jason's death.
- Celebrity Paradox: Iain Glen portrayed Jorah Mormont on Game of Thrones, a show that Rachel is a fan of and is seen watching in the first season. Rachel also happens to be a fan of the character Daenerys Targaryen, whom Jorah is strongly connected to.
- The Conscience: Throughout Season 2, as Dick is forced to confront his past sins, he starts hallucinating Bruce, who seems to act as his moral compass throughout the ordeal.
- Control Freak: Embeds trackers into Dick and Jason's arms to keep an eye on them. Dick didn't even know about his until Jason told him. Slides into Nightmare Fuel when you realize the only way Dick couldnt already know about the tracking device is if Bruce roofied him. Gets phenomenally worse, if youre aware of the pairs past reputation and what inspired Robins leash in the Batman Who Laughs.
- Eventually turns into a case of The Extremist Was Right due to Deathstroke's kidnapping of Jason Todd since his tracker was the only life line the new Titans had in regards to locating him.
- Crimefighting with Cash: The Trope Codifier. He owns a Fiction 500 Mega-Corp and lives in a very Big Fancy House.
- The Dreaded: Criminals are terrified of him. The first group of thugs Robin confronts in the series take one look at him, then much to Dick's frustration, immediately turn their attention to the skies and rooftops instead, because they're more afraid of Batman than alarmed that another superhero, let alone his protege', has found them. They think Robin is no threat without Batman around to back him up. This proves to be a painful mistake.
- Famed in Story: As one of the founding members of the Justice League with a career spanning decades, basically everyone in the world knows the Dark Knight, whether they are heroes or villains.
- Greater-Scope Paragon:
- He doesn't have much role, but is still essential to the backstory of Titans.
- Reaches a new level in season 2, where Bruce finally shows up. He only appears in a handful of episodes, but his mentor role ultimately transforms the Titans into a genuine superhero group. In "E.L._.O", he even brings the estranged Titans back together, though the season finale leaves it ambiguous as to whether it was really Bruce who appeared to Kory, Rachel, Donna, and Dawn.
- In Spite of a Nail: Like his Earth-Prime counterpart, he kills the Joker and then leaves Gotham though unlike his counterpart he decides to leave Dick the responsibility of protecting it. This makes him one of five versions of Batman who has killed with the other three being his counterparts on Earth-66, Earth-89 and Earth-99.
- Knight Templar Parent: One way to interpret him putting a tracking chip in Dick (and later on, Jason) wasn't out of Control Freak tendencies but rather so he could find them should they ever get into a terrible situation, such as getting kidnapped by one of his more insane foes.
- Morality Pet:
- Season 2 implies he's this via Dick's hallucinations in Bruce's self titled episode, with his imaginary Bruce attempting to get him to acknowledge his part in Jericho's death as well as trying to convince him to return to Titans tower.
- In fact, even though Dick's struggle to escape his mentor's shadow in an important plot point in the first two seasons, it is Dick's conscience manifesting as Bruce who finally convinces him to do so, while the real Bruce gifts him the suit for his new Nightwing persona.
- Not Wearing Tights: He is never shown wearing the Batsuit clearly. Justified since his only appearances in the show are outside of crimefighting.
- Old Superhero: Bruce in the Titansverse is middle-aged and has been operating as Batman for decades. This is further shown by the fact that his first Kid Sidekick, Dick, is in his late twenties.
- One-Man Army: If Dick's hallucinations are to go by, he could take care of an entire squad by himself.
- Ooh, Me Accent's Slipping: Played With. It's not so much that his American accent is bad, but it's really forced and unnatural. Even if you didn't know him, you could easily tell Iain Glen was not American.
- Parental Substitute: Took Dick in after the death of his parents, and is the latest in a long string of them to Jason.
- Putting the Band Back Together: In "E.L._.O", Bruce lures the female Titans to Elko Diner, where he convinces them to reunite the group. He claims to not know this in "Nightwing", however, leaving it ambiguous whether it was really him who did it.
- Support Party Member: In "Nightwing", he doesn't join the Titans fight Conner himself, but does hijack Mercy Graves' teleconference with Conner's bidders, distracting her long enough for the Titans to formulate a plan to reach Conner's conscience.
- Thou Shall Not Kill: Despite what Dick's Trigon-induced hallucination showed, Bruce still operates this way. He's just apparently quite brutal. Then he subverts this when he kills Joker in Season 3.
- Toxic Friend Influence: Well, more like "toxic Parental Substitute influence." Season 1 goes out of its way to imply that he's been a horrible influence on Dick (and possibly Jason). This appears to be mostly gone by season 2, which implies he may in fact be a Morality Pet to Dick. Season 3 brings it back by showing that Barbara has become disillusioned with him over this, and proves Dick's earlier dislike of him as being reasonable by being dismissive of the death of his closest allies and almost immediately trying to replace Jason.
- Two First Names: "Bruce" and "Wayne".
- Unseen No More: In season one, he only appeared briefly through indirect methods like a voiceover, as a hand on Dick's shoulder, or as The Faceless from far away. Season two changes this, with him actually appearing both in the flesh and in hallucinations.
Known to the world as Wonder Woman. She's Donna's adoptive elder sister and guardian whom she served as a partner.
A refugee from Krypton who is one of Earth's iconic and beloved superheroes.
- Alternate Self: On Earth-Prime), Earth-89note , Earth-96, Earth-99, Earth-167, Earth-F, and an unnamed Earth.
- Chronic Hero Syndrome: Apparently, just like in most versions, Clark is so afflicted by this that it was passed on to Conner, his clone. Conner can't help but be driven by the subconscious desire to help others in need and it's implied to be from the Genetic Memory given to him by Clark's DNA.
- The Cape: Implied. By all accounts, he's just as heroic and protective of people as he is in the comics.
- Farm Boy: Grew up in the Kent Farm on Smallville, per the norm.
- Famed in Story: He is so popular that people made shirts out of him.
- The Ghost: His existence is only confirmed and is yet to make an appearance.
- Physical God: Kory mentions how strong he is in passing saying that Conner got half of his DNA from a man who can "lift skyscrapers and fly faster than light".
- Two First Names: "Clark" and "Kent".
Species: Human-Atlanean Hybrid
A veteran superhero and Garth's mentor.
Played by: Savannah Welch
Commissioner Gordon's daughter and a member of the Bat Family.
- Alternate Self: On Earth-Prime, Earth-66, Earth-167, and Earth-203.
- Broken Pedestal: To Batman, her father, and superheroes in general. Upon becoming police commissioner, she believes that Gotham needs to be changed so as to stop relying on heroes, considering the messy legacy both Batman and her father's partnership left behind.
- Composite Character: She is wheelchair-bound like her comics counterpart, but she's become police commissioner like her Batman Beyond iteration, albeit much younger, like the Batman '66 comics crossover with Wonder Woman '77 revealed.
- Decomposite Character: Here, Oracle is a computer program, rather than Barbara herself.
- Disabled in the Adaptation: Disabled a bit differently, it seems. She's paraplegic in the comics and uses a wheelchair. This version is an amputee and has lost one of her legs, and still uses a wheelchair so she may still be paraplegic on top of that. note .
- The Ghost: Her existence was only confirmed in the first season until she appeared in Season 3.
- In Spite of a Nail: Like her Earth-203 counterpart she was shot by the Joker and became wheelchair-bound, but like her Earth-66 counterpart she replaced her father as commissioner of the GCPD.
- Nice Job Breaking It, Hero!: She clears a sniper to shoot Red Hood. Nightwing ends up shot instead and Jason gets away.
- Old Flame: Six years before the show started, Dick and Barbara had a fling. They rekindled their feelings and relationship upon Dick coming to Gotham in order to stop Jason.
- Two First Names: "Barbara" and "Gordon".
- Adapted Out: This incarnation doesn't have Crazy Jane and Cyborg.
- Alternate Self: Both Word of God and Crisis on Infinite Earths (2019) confirm that they're not the ones seen in Doom Patrol (2019).
- Body Horror: As detailed by Dysfunction Junction below, each member of the team is broken in every sense of the word.
- Comic-Book Movies Don't Use Codenames: All of them are not addressed by their superhero names, nor is the group addressed as Doom Patrol (despite the episode title being just that).
- Decoy Protagonist: Doom Patrol (2019) was greenlit a few months before the Titans (2018) premiere and their guest-appearance in the latter show makes it seem like an Early-Bird Cameo. Then Doom Patrol premiered and their characterizations do not sync with their appearance in Titans, most notable cases being Dr. Caulder being played by a different actor, the lack of references to Gar, and Jane's existence. While it took until Crisis on Infinite Earths (2019) to confirm, it's eventually revealed that the two teams are from two different universes.
- Dysfunction Junction: The Doom Patrol are gathered together by this. To wit:
- Caulder is confined to a wheelchair.
- Cliff has no body of his own and has to live inside that of a cold steel robot.
- Larry's body is heavily charred and lethally radioactive.
- Rita's powers are debilitating, and she literally breaks down before shooting a movie.
- Early-Bird Cameo: Their appearance serves as a reminder to the viewers that a Doom Patrol (2019) show is coming up.
- Family of Choice: While they're prone to Snark-to-Snark Combat, they are much more stable and united compared to the main Doom Patrol.
- Ragtag Bunch of Misfits: They're a bunch of superpowered outcasts banded together to do good.
- Small Role, Big Impact: They only appeared in a single episode but they're the ones who took Gar and trained him.
- Spared by the Adaptation: The reason Beast Boy was able to join the Teen Titans in the comics is because the Doom Patrol is dead. They are very much alive here.
Dr. Niles Caulder / The Chief
Played by: Bruno Bichir
The Leader of the Doom Patrol.
- Genius Cripple: An intelligent scientist who's bound to a wheelchair. He's walking in Titans, having somehow recovered in the past, but is soon back in the chair.
- Good Is Not Nice: He saves and harbors people thought to be doomed with his unconventional science, and ultimately wants to help humanity. He's stern and overly controlling of his patients, brushes off the issue of consent, and even shoots Gar with a tranquilizer when he protests and threatens him.
- Ill Boy: Niles appears to be diabetic, or at least has a fondness for chocolate, as he keeps a filing cabinet full of them in his lab.
- Race Lift: He is Caucasian in the comics but is played by Mexican actor Bruno Bichir.
Species: Enhanced Human
Played by: April Bowlby
A former actress who was mutated by a strange gas.
- '50s Hair: Has the "Hollywood curls" style ala Marilyn Monroe.
- Adaptational Superpower Change: In the comics her powers are Mister Fantastic-style ability to stretch her body, plus grow or shrink. Here her "default" state is a semi-solid blob of flesh which can flow and slip through small openings, and it takes a great deal of mental control for her to hold herself in human form. She has on few occasions displayed the ability to stretch her limbs and the volume her body occupies can change drastically, implying that she could eventually manage the same things as her comics counterpart.
- Adaptation Personality Change: A Nice Girl and the group's Team Mom in the comics, but more of a narcissistic former Hollywood diva here, who nonetheless has a sweet side to her as well.
- Big Eater: When she joins the others for dinner and introduces herself to Rachel, she piles her plate with a small mountain of food. Justified, since she says that she requires a lot of caloric intake to help maintain her form.
- Blessed with Suck: Compared to her comic counterpart, Rita's powers are pretty terrible. Unlike the comic where she is essentially Mister Fantastic, in the show, she is essentially a giant blob of flesh in her neutral form. The only real benefit to this power is that she is able to move through very small openings, as she is super malleable. On the downside, she requires constant mental focus to maintain her physical form, any distractions or distress tends to cause her to grotesquely lose her form. It's clear that she hates her "power".
- Blob Monster: Introduced lying in bed as a formless blob and has to reshape herself when she awakens. This requires a conscious effort on her part and she has difficulty maintaining it, especially when stressed or emotional.
- Body Horror: Seeing her dissolve is....not a pretty sight.
- Fiery Redhead: An auburn-haired woman known for her pridefulness .
- Hospital Hottie: In a medical uniform, she wears it well and is not less a Ms. Fanservice in it.
- Lady Inred: Her formal introduction sees her wearing a sultry red dress.
- Large Ham: Her acting. Also, pretty much Rita in general. Larry comments that, in order to use her powers, first she has to "emote."
- Ms. Fanservice: April Bowlby is very attractive, and her first appearance includes a flattering red dress with Absolute Cleavage. Unfortunately, during a Superpower Meltdown, she most certainly is not.
- Sleeps in the Nude: Implied. Her first scene introduces her in her Blob Monster state in her bed covered in a blanket.
- The Smurfette Principle: She's the only female member of the group.
- White-Dwarf Starlet: Clings to her days of stardom.
Captain Lawrence "Larry" Trainor, USAF
Species: Enhanced Human
Played by: Matt Bomer (voice & flashbacks/unsuited), Dwain Murphy (suited actor)
An Air Force pilot who was exposed to negative energy.
- Ace Pilot: Larry was a revered pilot in the U.S. Air Force prior to his accident.
- Badass Longcoat: A constant attire for him, likely to conceal the bandages on his body.
- Bandaged Face: His entire body is covered with bandages as a result of exposure to negative energy. When Raven asks if it's because he's invisible, Larry can only scoff "wouldn't that be nice?"
- Body Horror: His entire body is covered in horrific burns from the plane crash that followed his merging with the Negative Spirit.
- Cool Shades: Wears them out of necessity as a result of the accident that disfigured him, even indoors and at night.
- Good-Looking Privates: Larry was a Tall, Dark, and Handsome USAF captain.
- Military Superhero: Larry was a captain in the U.S. Air Force long before becoming a member of Doom Patrol.
- Nice Guy: Cooks dinner for the rest of the Doom Patrol and is extremely accommodating to Raven, in contrast to Robotman who insists she leaves so as to not upset the Chief. He also gives Starfire a chance to back off first when she and Dick show up to rescue Raven, warning her that she wouldn't want to see what he's capable of.
- Person of Mass Destruction: His body constantly oozes powerful radiation, and he gives a rather stern warning to Starfire not to fight him, and she ultimately backs down.
- Race Lift: White in the comics, but played by Dominican-Canadian actor Dwain Murphy. Though since Negative Man is practically never seen without his full body costume, this isn't really noticeable.
- Team Chef: Is the one to cook for the whole group and apparently a talented one at that.
- You Wouldn't Like Me When I'm Angry: His warning to Starfire when they face off:Larry: "Don't make me fight you. You don't want to see what I really am."
Clifford "Cliff" Steele
Species: Enhanced Human
Played by: Brendan Fraser (voice), Jake Michaels (suited actor)
A professional car racer who had his brain transplanted into a robot body after a nigh-fatal crash.
- Badass Driver: He was a former racecar driver and in one of his races, avoided an oncoming vehicle which won him the race.
- The Big Guy: The biggest heavy hitter on the team.
- Brain in a Jar: Albeit, a nigh-indestructible one.
- Cyborg: A human brain inside a mechanical body.
- Forgot He Was a Robot: He blinks for unknown reasons.
- Gentle Giant: He's a large robot and is very chummy.
- Noisy Robots: His micro-movements create sounds.
- Sense Loss Sadness: Can no longer feel, taste, or smell anything anymore and is very envious of Raven being able to enjoy her dinner.
- Series Mascot: The most recognizable full-fledged member (not counting Beast Boy, who's more associated with the Titans) and the only one to be in every iteration of the team.
- See his Titans page entry.
Played by: Elliot Knight, Jayden Marine (young)
Hank Hall's brother and the original Dove.
- Adaptation Relationship Overhaul: He and Hank are full siblings in the comics but are only half siblings in the show.
- Adaptational Angst Upgrade: He clearly blames himself for the sexual abuse his brother went through.
- Adaptational Personality Change: The Don of the comics was a pacifist who avoided causing physical damage to others as much as possible for a superhero. Here he was more than willing to help beat up the pedophiles he and Hank went after and overall seemed quite fight-happy. Although, even Comics!Don would have been hard-pressed to treat pedophiles with pacifism.
- Beware the Nice Ones: He was a perfectly nice man, but when the headmaster of the college they attended treated him with more favoritism than Hank and implied she was going to throw the older brother under the bus Don not only got confrontational but actively dared her to expel them.
- Big Brother Instinct: Inverted. He's the little brother, but by how much is uncertain. Regardless, he was shown to be very protective of Hank and even went so far as to report his brother's head injury behind Hank's back in a bid to make him rest. He also defends him as well because the headmistress implied that she is going to ignore the injuries that his brother has which makes him not very happy with that sort of treatment so he decides that he has enough of her and dares her to just kick him and his brother out showing just how pissed off he is with her.
- Blue Is Heroic: His costume has blue accents.
- Dies Differently in Adaptation: Don famously dies in a Heroic Sacrifice in the comics. Here, it's because of a freak road accident.
- Disappeared Dad: For whatever reason, neither his or Hank's fathers are in their lives.
- Dropped a Bridge on Him: Died unceremoniously in a freak road accident.
- It's All My Fault: He very clearly blamed himself for what happened to Hank when they were kids.
- Missing Mom: She dies sometime between the weight room incident and the brothers' time at college.
- Pædo Hunt: He was the one who suggested he and Hank become heroes for this express purpose.
- Precision F-Strike: He gives out one to the headmistress as he dares her to kick him and his brother out clearly having enough of the favouritism that she is giving him.
- Posthumous Character: Killed when a car crashes into him several years before the events of the series.
- Race Lift: White in the comics, here portrayed by British-Nigerian Elliot Knight.
- Sibling Team: With Hank, before his death.
An ally of Donna Troy's.
