Robin: Voiced by Jesse McCarthy. In this series, he’s a 13 year old Dick Grayson, but he’s been Robin for a few years time.
Kid Flash: Voiced by Jason Spizak. He’s Wally West and he’s 15 years old. Not quite as fast as the Flash.
Aqualad: Voiced by Khary Payton (who also provided the voice for Cyborg). He’s not Garth, but Garth will be appearing on the show, we’re assured (no word on whether Garth would be Aqualad or Tempest). And confirmed on the panel: This new Aqualad’s father is Black Manta.
Superboy: Voiced by Nolan North. Superboy is close to the comic book version. He’s a 16-week old clone, and he’ll eventually assume the Conner Kent secret identity.
Miss Martian: Voiced by Danica McKellar. Martian Manhunter’s 16-year old niece.
Artemis: Voiced by Stephanie Lemelin. This 16-year old heroine is neither Arrowette, nor Wonder Girl nor Speedy. But she is an existing character in the DCU! The panel refused to reveal who, however.
Speedy: Not part of the team, but Speedy (the Roy Harper version) was seen in the trailer.
