Batman originally debuted as a stand-alone character fighting the forces of evil. Then, Robin was introduced as a side-kick and junior-counter to Batman to appeal to a youngger audience. From 1947 on Robin has associated his own fan base and his popularity sparked his reappearance as the independent superhero, Nightwing. What is it about Robin that appeals to fans? And, why did Batman the series need such a supporting character?
Batman is a lonely and solid figure, even despite the later presence of Alfred Pennyworth. Earlier in the comics, before the emergence of Robin, Batman had only had himself to talk to. Scenes typically depicted Batman thinking rather than talking out loud, which provided a fairly bland script. Batman needed a companion who would offset his dark broodiness and provide the readers with a bit of lightheartedness. Consequently, the partnering of Batman with Robin the Boy Wonder has been one of the most successful match-ups in comic book history.
The character of Robin is a constantly evolving one. Readers are able to observe his transformation from an orphan to a superhero. Fans can identify with Robin's “normalcy” over other superheroes that have outrageous supernatural powers. Robin's success is that he's the opposite of a static character. Robin has evolved from being Batman's sidekick to leading the Teen Titans, to eventually becoming the protector of Gotham's neighboring city. After the death of Batman in Batman RIP and Final Crisis, readers could breathe a sigh of relief due to Dick Grayson taking up his mentor's identity as the new Batman. Overall, Robin is a character that delivers on personality and likability. He has pure staying power as attestable by the fact that he's now over sixty years old … and counting.
