What if instead of being adopted by an altruistic athletic billionaire, Robin was Holden Caulfield in J.D. Salinger's The Catcher in the Rye? Andrew Makes Comics has imagined such a pan-textual pairing. See Robin the Boy Wonder become a man.
For another strangely reimagined classic, see The Great Gatsby as a 1980s Nintendo game.
Hat tip to Jen!
