In this version of the show, Batgirl and Robin were the main উৎস of sane humor, where as ব্যাটম্যান is his regular grim and gritty self, as opposite to Bruce Wayne, who plays a আরো humorist character while keeping face. As this is, I do believe ব্যাটম্যান needs Batgirl and Robin so he knows how to have a good time while fighting crime, and the JLA knows he does have a softer side.
