Watch "Arrow's" Comic-Con trailer below:
The live-action Teen Titans television show is straying from its action-packed cartoon past, choosing instead to go for a grittier, grimdark tone this time around. In Warner Brothers' most recent trailer for the upcoming DC Universe show, Brenton Thwaites prowls in the shadows as Dick Grayson, the first Robin, and murders a group of alleyway thugs. The final member is Starfire, played by Anna Diop, a fugitive alien princess with the ability to fly and shoot energy from her hands. Teagan Croft also stars as Raven, the daughter of a powerful demon whose dark powers are controlled by her emotions, alongside Ryan Potter, who plays Beast Boy, a green-skinned teen who can turn into any animal he can think of. He breaks the neck of the last survivor and growls "F— Batman," setting the tone for the rest of the trailer.
Premiering on DC Universe for on-demand streaming later this year, Warner Brothers dropped a five-minute sneak-peek trailer featuring several scenes from the upcoming show. Back by popular demand, "Young Justice" returns with a third season focusing on the Outsiders team. Featuring an invasion by Black Beetle, the abduction of Tara Markov and Aqualad going deep undercover to spy on Black Manta, the Outsiders look to be plenty busy when the show returns.
