The heroes confirmed to appear so far other than Robin are Starfire, Raven, Beast Boy, Hawk and Dove, and members of the Doom Patrol, although the Doom Patrol heroes are unlikely to stick around.
There may even be a second Robin showing up, and Wonder Girl is a possibility as well!
The Harley Quinn series isn’t the only one coming to DC Universe when it debuts later in 2018.
The arguably most talked-about upcoming show is the long-awaited Titans project, which will feature none other than Dick Grayson as Robin leading a group of young superheroes.
