Warner Bros.' live-action "Titans" series just added another hero to its roster. On Twitter, DC Entertainment president Geoff Johns appeared to confirm another longstanding Titan's involement in the series: Beast Boy. Johns included Beast Boy's name as a hashtag, which suggests that the character will appear in the upcoming series.

Yes!! Very happy to be writing the Titans again and working with this crew! Extremely excited. Will be something very different... #BeastBoy https://t.co/D4sl3Gip7y

The original announcement from Warner Bros. confirmed only three other team members: Dick Grayson (presumably as Nightwing), Starfire and Raven. The Titans have had a diverse roster over the years, but it seems as though the live-action series's team is taking shape like the animated "Teen Titans" series that aired in the early 2000s, which featured a team that included Robin, Starfire, Raven, Beast Boy and Cyborg. However, Cyborg has not yet been announced for the live-action series, and his involvement seems unlikely since the character will star in Warner Bros.' upcoming "Justice League" film.

In the comics, past versions of the Titans team also included Kid Flash, Aqualad, Blue Beetle, Superboy, Wonder Girl and more. Presently, DC Comics' "Titans" stars Nightwing, Wally West's Flash, Red Arrow, Donna Troy, Garth, Bumblebee and more. As such, the live-action series has plenty of young DC heroes to choose from as Warner Bros. develops the series. What's more, Johns himself oversaw the relaunch of "Teen Titans" at DC Comics in the early 2000s, which means he'll be a valuable resource in "Titans'" creation.

Written by Akiva Goldsman (“Batman Forever,” “Transformers: The Last Knight”), Johns and Greg Berlanti, “Titans” is billed as an action-adventure based on the enduring DC Comics franchise.

Warner Bros. Television announced the new series earlier today, describing the Titans as “a group of young soon-to-be superheroes recruited from every corner of the DC Universe,” which may suggest the lineup may reach beyond the traditional membership. A live-action “Titans” series has been in development at TNT before being shelved by the cable channel in 2014. However, Johns pledged in early 2015 that DC still had plans for the project.

“Titans” will be executive produced by Johns, Goldsman, Berlanti and Sarah Schechter (“Arrow,” “DC’s Legends of Tomorrow,” “The Flash,” “Supergirl”). The series will air on a new DC Comics-branded digital platform that will launch in 2018. No official release date has yet been announced.
