The world of superheroes on the small screen won't be expanding on TNT.

In his first executive session as the president of TNT and TBS, Kevin Reilly revealed Thursday at Television Critics Association's winter press tour that the former network has passed on superheroes-to-be drama Titans.

"We just decided it wasn’t quite where we wanted to go," he said.

The project, from Warner Horizon Television and DC Comics, also had high-profile names attached in Akiva Goldsman (A Beautiful Mind) and Marc Haimes.

Based on characters from DC Comics, Titans revolves around a group of young superheroes-to-be who are recruited from every corner of the DC universe. The action-themed drama centers on Dick Grayson, who emerges from the shadow of Batman to become Nightwing, the leader of a fearless band of new superheroes including Starfire, Raven and more. The project is described as a dramatic adventure series that will explore and celebrate one of the most popular comic book titles ever.

The team of teen superheroes first appeared in a 1964 issue of The Brave and the Bold as a "Junior Justice League" featuring Robin (aka Dick Grayson), Kid Flash (Wally West) and Aqualad (Garth). They were later joined by Wonder Girl (Donna Troy) and Green Arrow's sidekick, Speedy (Roy Harper). The series was later revived in 1980 and relaunched as The New Teen Titans, aging the characters to young adults.

The new iteration of Titans neared a pilot order at TNT in September 2014, several months before Reilly took over. However, Reilly made it clear Thursday that he hopes to take the network in a drastically new direction with the upcoming end of Rizzoli & Isles and new series Animal Kingdom and Good Behavior.

Superhero series have proven successful for broadcast nets including The CW (The Flash, Arrow and the upcoming Legends of Tomorrow), Fox (Gotham) and ABC (Marvel's Agents of SHIELD and Agent Carter). FX next plans to tackle the genre with the new project Legion from Fargo's Noah Hawley.
