Here's something I've been wondering about . . . and, no, this is not a "dump Damain" rant.
Robin was conceived as more of "a laughing, fighting, young daredevil who scoffs at danger" (wording from Detective Comics 38, 1940). Tim became the third Robin to Batman because he felt Batman needed a lighter, brighter counterpoint to keep Batman from being too dark and all.
But Damian ain't it. He's not a bright, smiling, happy-go-lucky kid. He's killied before (even before Nobody), and he could easily do so again in the future.
Should he maybe take on a different identity to reflect his slightly darker, more serious side?
