Synopsis for "The Rainbow Batman"
Dick Grayson saves a girls life during a robbery. In the process, he injures his arm. He does see the crooks and can identify them later. As he searches for the crooks as Robin, Batman wears several different colored costumes. Eventually Robin spots the thieves, allowing Batman to apprehend them. Afterward, Batman goes back to his old costume. He wore the special ones to draw attention to himself and away from Robin, as people might realize Robin had an injured arm like Dick Grayson’s.
