Based on the DC Comics superhero team Teen Titans, the series depicts a group of young heroes who join forces in their fight against evil.

Featured as members of the eponymous Titans are Dick Grayson (Brenton Thwaites), Kory Anders (Anna Diop), Rachel Roth (Teagan Croft), Gar Logan (Ryan Potter), Jason Todd (Curran Walters), Donna Troy (Conor Leslie), Hank Hall (Alan Ritchson), Dawn Granger (Minka Kelly), Rose Wilson (Chelsea Zhang), Conner Kent (Joshua Orpin), and Tim Drake (Jay Lycurgo).

The first members of the team to appear in the series are Batman's former vigilante partner Dick Grayson, extraterrestrial Kory Anders, empath Rachel Roth, and shapeshifter Garfield "Gar" Logan.

Dick is later revealed as one of the original Titans, alongside half-Amazon Donna Troy and crime-fighting duo Dawn Granger and Hank Hall.

After the Titans reform, the team is joined by Batman's new partner Jason Todd, assassin Rose Wilson, Superman's genetic clone Conner Kent, and aspiring vigilante Tim Drake.

The season also depicts Dick's efforts to distance himself from his mentor and his Robin persona, while Kory struggles with a bout of amnesia that leaves her unaware of her true identity.

The Titans' return, however, leads to the reemergence of feared assassin Deathstroke, whose prior conflict with the original team caused their disbanding.

As Deathstroke attempts to eliminate the heroes, the original Titans are forced to face him again, while other threats emerge from the malevolent Cadmus Laboratories and Kory's sister Blackfire.

Also depicted are Kory's tense reunion with Blackfire, who seeks redemption for past actions and Donna's return from the afterlife following her death in the previous season.

[37] By December, a pilot written by Akiva Goldsman and Marc Haimes was ordered that would feature Dick Grayson emerging from Batman's shadow to become Nightwing, the leader of a band of heroes including Starfire, Raven, Hawk and Dove, and Oracle.

[38][39] In May 2015, TNT president Kevin Reilly said that they hoped to have the casting locked down by the start of filming and that the show would be "very true" to the comics and "groundbreaking".

[45] Johns, who had spent seven years developing the material with Goldsman, said in October 2018 that the project depended on securing the rights to Dick Grayson.

[10] In early September, Alan Ritchson and Minka Kelly were cast in the recurring roles of Hank Hall and Dawn Granger, respectively.

[70] In January 2018, Seamus Dever was cast in an undisclosed role that would later be revealed as Trigon,[71] and a month later, members of the Doom Patrol were announced with Bruno Bichir as the Chief,[72] April Bowlby as Rita Farr,[73] Jake Michaels as Cliff Steele,[74] and Dwain Murphy as Larry Trainor.

[31] In January 2022, Joseph Morgan, Franka Potente, and Lisa Ambalavanar were cast as season 4 characters Brother Blood, Mother Mayhem, and Jinx, respectively.

[95] Production was put on hold due to the July accidental death of special effects coordinator Warren Appleby before resuming.

The site's critical consensus states: "Despite a few tonal growing pains, Titans does justice to its source material and truly shines when its titular ensemble finally assembles".

[117] Susana Polo of Polygon praised Titans for "tempering brutal violence and dark subject matter with humor—and by giving its characters plenty of time to stretch, breathe and become attached to one another".

[121] Charlie Ridgely of ComicBook.com wrote that Diop "conveys so much wonder and intrigue with her subtle and genuine expressions, but there is a consistent fierceness and tenacity that is always lurking just beneath the surface".

[123] Forbes contributor Merrill Barr compared the show to The CW's Riverdale, describing it as "a dark and gritty series very far removed from the image the Teen Titans have garnered through a variety of animated outings over the last decade".

[124] Rob Salkowitz of Forbes wrote that Titans "somehow managed to deliver on the dark-and-foreboding tone that the early DC movies so conspicuously got wrong".

[125] Kevin Yeoman of Screen Rant was critical of the show's excessive violence, writing that Titans "doesn't put forward any new or particularly compelling thoughts about its characters or about superheroes in general".

[126] Similarly, Vinnie Mancuso of Collider said that "if you're just a fan of some good old-fashioned ultra-violence and moody storytelling, this simply isn't a well-done example of that".

[132][133][134] Developed by Jeremy Carver (who wrote the pilot) for Warner Bros. Television and Berlanti Productions, the series features the Chief, Cliff Steele, Larry Trainor, Cyborg, Rita Farr, and Jane as the members of eponymous Doom Patrol.

April Bowlby, Matt Bomer, and Brendan Fraser reprise their roles as Rita, the voice of Larry, and the voice of Cliff, while Matthew Zuk and Riley Shanahan replace Dwain Murphy and Jake Michaels for the physical portrayals of Larry and Cliff[135] and Timothy Dalton replaces Bruno Bichir as the Chief.

[139] The Titans incarnations of Hank Hall, Jason Todd, Rachel Roth, Kory Anders, and Dawn Granger make cameo appearances in the Arrowverse crossover event "Crisis on Infinite Earths", with Alan Ritchson, Curran Walters, Teagan Croft, Anna Diop, and Minka Kelly appearing in their respective roles through archival footage.
