Cast and characters
Brenton Thwaites as Dick Grayson / Robin / Nightwing: The leader of the Titans and former vigilante sidekick of Batman, seeking to move past his mentor and his Robin persona. A member of the original team, he re-forms the Titans while assuming the new identity of Nightwing. Viewing his character as a "reluctant leader", Thwaites said Dick is "trying to figure out who he is at the same time he's trying to keep the crew protected and safe". Tomaso Sanelli, Viktor Sawchuk, and Taj Levey play the young Dick.
Anna Diop as Koriand'r / Kory Anders / Starfire: An extraterrestrial royal from the planet Tamaran who has the ability to absorb and redirect solar energy. Sent to Earth to assassinate Rachel, a bout of amnesia causes Kory to forget her mission and join the Titans. Diop commented the character has a "really innocent, naïve, pure, fun, curious thing about her", which she sought to bring to her portrayal, and enjoyed playing an alien due to being a Senegalese immigrant.
Teagan Croft as Rachel Roth / Raven: An empath born to a demon father and human mother. At first understanding little of her lineage and abilities, Rachel's powers lead her to Dick and subsequently becoming a member of the new Titans. Croft noted Rachel's relationship with Dick is "more of a father-daughter relationship" since they both "share the same feeling of abandonment".
Ryan Potter as Gar Logan / Beast Boy / Changeling: A shapeshifter who can transform into a green version of various animals, mainly a tiger, after receiving a drug that cured him of a lethal disease. Gar previously lived with the Doom Patrol before joining Dick's new Titans team. A fan of the character since he watched the animated Teen Titans series, Potter described Gar as bringing "a warmth to the show" through "humor and lighthearted moments".
Curran Walters as Jason Todd / Robin / Red Hood (seasons 2–4; recurring season 1): Dick's successor as Batman's vigilante sidekick who is brought into the new Titans team at the request of Bruce Wayne. According to Walters, Jason has both a "fun" and a "dark side" and transitioning between the two was the most challenging aspect of portraying the character.
Conor Leslie as Donna Troy / Wonder Girl (seasons 2–3; guest season 1): A half-Amazon sharing their enhanced physical abilities. Formerly Wonder Woman's sidekick, she befriended Dick at an early age and was on the original Titans team. Leslie noted Donna has "a brother-sister friendship" with Dick and the two "understand each other in a way no one else ever will". Andi Hubick and Afrodite Drossos portray the young Donna.
Minka Kelly as Dawn Granger / Dove (seasons 2–3; recurring season 1): A vigilante who serves as a tactical counterpart to her partner and boyfriend Hank. Kelly described Dawn's fighting style as "more that of a dance" due to the character's background in ballet, jiu-jitsu, and gymnastics, whereas Hank "is a brute and just blows stuff up".
Alan Ritchson as Hank Hall / Hawk (seasons 2–3; recurring season 1): The aggressive half in a vigilante duo composed of himself and his girlfriend Dawn. In addition to forming the Hawk and Dove team with his half-brother Don, he was part of the original Titans. Initially reluctant to take the role because he previously portrayed Aquaman on the series Smallville, Ritchson said he accepted the part after hearing a pitch from series co-creator Geoff Johns. Tait Blum portrays the young Hank.
Esai Morales as Slade Wilson / Deathstroke (season 2): A biologically enhanced assassin and former Delta Force operator who has a history with the original Titans. Morales stated Deathstroke's conflict against the Titans is "personal" for him "because you don't mess with a man's family".
Chelsea Zhang as Rose Wilson (season 2): Deathstroke's daughter, who shares his enhanced reflexes and regenerative healing. For her performance, Zhang said she would reference Rose's comic depiction where "her attitude, her sass, and her sarcasm is written all over the books".
Joshua Orpin as Subject 13 / Conner Kent / Superboy (seasons 2–4): A genetic clone of Superman and Lex Luthor, possessing the abilities and personality traits of both. Created at Cadmus Laboratories, he comes into contact with the Titans after escaping from the facility with Krypto. Acknowledging he was fascinated by Conner's internal conflict, Orpin noted "he has an extraordinary capacity for good, and for evil" where "nothing is black and white to him, and yet everything is". Body double Brooker Muir plays the character in the first season.
Savannah Welch as Barbara Gordon (season 3): The commissioner of the Gotham City Police Department, succeeding her late father. Welch, who is an above-knee amputee, found it important to "represent the reality of a woman who is chair-bound as closely as possible" in her performance to ensure "anyone who is chair-bound, or in a position that is close to that, does truly feel represented".
Vincent Kartheiser as Dr. Jonathan Crane (season 3): A criminal psychologist who exploits the fears of his victims. Incarcerated at Arkham Asylum, he assists the Gotham City police with their investigations. Showrunner Greg Walker described Crane as "a perfect villain" whose knowledge of phobias results in him "working off your feelings and your emotions, and that's where we want to live".
Damaris Lewis as Komand'r / Blackfire (season 3; guest season 2): A Tamaranean royal and Kory's younger sister. Lacking their family's ability to generate fire, she holds a strained relationship with Kory. Lewis, noting that Blackfire's nature is the result of not being accepted by her family and society, said she was drawn to playing a villainous character because "the villains are the ones who don't fit in".
Jay Lycurgo as Tim Drake / Robin (season 4; recurring season 3): A resident of Gotham who is a big Batman and Robin fan and wishes to be a hero like them. He joins the Titans at the end of the third season.
Franka Potente as May Bennett / Mother Mayhem (season 4): A witch and the leader of a blood cult who masquerades as an archaeologist.
Joseph Morgan as Sebastian Sanger / Brother Blood (season 4): A taxidermist and app designer who has a strange connection to the Temple of Azarath.
