Robin (real name Richard John "Dick" Grayson) is the main central character of the Teen Titans series. He is the leader and one of the five founding members of the Teen Titans. Before that, he was trained by, and served as the sidekick to Batman. He is also Starfire's main love interest and finally becomes her boyfriend in the series' finale movie.

With his fellow Teen Titans, self-appointed protectors of Jump City, Robin encountered Slade, the mastermind villain who is Robin's arch rival, responsible for the majority of the villains the Titans clashed with during this time, including the H.I.V.E. and Thunder and Lightning

Robin is usually shown in just his costume, which is consisted of green tights with black ankle-high steel-toed boots, green elbow-high gloves, a short-sleeve green t-shirt underneath a red armored vest with a yellow letter "R" inside a black circle over his left pectoral muscle, a yellow utility belt and a black cape that has a yellow interior. He always wears a black-and-white domino mask, and usually has his black hair spiked backwards. He has light skin and an athletic build. When he is briefly shown as Slade's apprentice, he wears a black bodysuit with armor plating on the legs, knees, forearms, and shoulders. The top-half of his suit is split into black and orange sides and an ash-gray utility belt.

Robin is a natural-born leader. He is heroic, noble, kind, selfless, stoic, stubborn, brooding and usually serious in tone, but has had a fair number of funny moments. In DC Comics and other incarnations, Robin is even toned and playful despite some outbursts of rage, such as when he learns of his parents' killer and when he eventually stops working as Batman's sidekick (a situation that is mentioned in a roundabout way in the episode "Go!"). However, in this series, Robin's personality is closer to Batman's; serious, stern, strict and obsessed with hunting down criminals, which is most prominently displayed in the first season, where he goes so far as to masquerade as a villain to catch Slade. Despite this, Robin does maintain a more relaxed, at times even playful side, which he sometimes expresses when the team is not actively engaged in crime fighting. He was also not mad at the other Titans for dressing up as him and told them the mask makes him look cool.
