The first season of the American superhero streaming television series Titans premiered on DC Universe on October 12, 2018, and concluded on December 21, consisting of 11 episodes.

In the first season, vigilante Dick Grayson (Thwaites) leaves Gotham City for Detroit in an effort to distance himself from his mentor Bruce Wayne.

Joined by Kory Anders (Diop), an amnesiac woman with solar-based powers, and Gar Logan (Potter), an animal shapeshifter, the four battle a threat that puts the entire world at risk.

The characters introduced would later be featured in an eponymous series on DC Universe, with April Bowlby, Matt Bomer, and Brendan Fraser reprising their roles as Rita Farr, Larry Trainor, and Cliff Steele, although it occupies a separate continuity from Titans.

Maisie Williams and Rory McCann appear in archive footage from the Game of Thrones episode "First of His Name" as Arya Stark and Sandor Clegane.

[1] 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, Oracle, and Hawk and Dove.

Teagan Croft was cast as Rachel Roth,[17] followed by Anna Diop as Kory Anders,[18] Brenton Thwaites as Dick Grayson[19][20] and Ryan Potter as Gar Logan.

[28] Members of the Doom Patrol are portrayed by Bruno Bichir as the Chief,[29] April Bowlby as Rita Farr,[30] Jake Michaels as Cliff Steel,[31] and Dwain Murphy as Larry Trainor.

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".

[40] 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".

[41] Describing Anna Diop's performance of Kory Anders as the strongest aspect of the first three episodes, Charlie Ridgely of Comicbook.com wrote that "she 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".

[43] 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".

[44] 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".

[45] 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".

[47] Evening Standard reviewer Guy Pewsey stated that the series was "enjoyable and watchable" and although questioned whether Brenton Thwaites could "pull off the role of leader of a group of crime-fighters" as Dick Grayson; he called Diop's performance a "highlight" of Titans.
