TNT is getting into the superhero game, as the cable channel and Warner Bros. are nearing a deal on a pilot production order for “Titans,” a one-hour live-action drama based on younger characters in the WB-owned DC Comics universe.

Focusing on known names (at least to comicbook fans), the show would center on Dick Grayson, the former Robin who emerges from Batman’s shadow to become Nightwing and the leader of a fearless band of heroes who include Starfire and Raven. Scribes Akiva Goldsman (“Batman Forever”) and Marc Haimes (“The Last Word”) will serve as exec producer and co-exec producer, respectively, with Warner Horizon Television producing.

Shows based on comicbook characters are en vogue right now, given the popularity of AMC’s “The Walking Dead,” ABC’s “Agents of SHIELD” and the CW’s “Arrow.” Three other shows based on DC characters are launching this fall: “The Flash” on the CW, “Constantine” on NBC and “Gotham” on Fox. This deal is somewhat apropos, though, as DC Comics has a character named TNT. Known for his — ahem — explosive personality traits and radioactive powers, the character was popular after World War II.

Goldsman is repped by WME and Hansen Jacobson. Haimes is repped by WME and Management 360.

The animated series “Teen Titans,” which also focused on these characters, previously aired on Cartoon Network and the WB. “Teen Titans Go!” began airing in 2013 on Cartoon Network.
