Dick GraysonNote...It is never actually mentioned throughout the series, but there are many clues!!In the episode "Go!", which is supposed to take place at the very beginning of the series, Robin stops a bank robber and:Bank Robber (To Robin), "Hey, this isn't your town. Aren't you supposed to be with...?"Robin. "Just moved here. And from now on, I work alone."According to the comics (there's a few different versions), the original Robin(Dick Grayson) is morally against something that Batman does-- usually he's too violent for Robin-- and so, Robin leaves Batman and ends his sidekickship. This is quite ironic, considering that Robin was the FIRST sidekick ever created, first appearing in DETECTIVE COMICS #38 in 1940, and now, some 69 years later, Robin is no longer sidekick, but a fully graduated hero.Continuing with the comics, Robin moves to Bludhaven and adopts a new super-hero identity, known as Nightwing. In episode 14 of Teen Titans, "How Long Is Forever?", Warp sends Starfire into the future, in which she meets an older version of the Robin she once knew-- he is now called Nightwing. Considering that Dick Grayson is the ONLY Robin who develops into Nightwing, this is a pretty big hint of Robin's secret id.More proof: The comic version of Grayson had a long term romance with Starfire.

Robin was the first, but the name of the very first of the main three Robins is Dick Grayson. He later became leader of the Teen Titans, and is now known as Nightwing.
