« Batman and the Turtles grapple with the laws of Krang’s combined universe, desperate to return their two worlds to their original states. But there are some who do not want things set right. In this reality, the Laughing Man runs the Smile Clan, the most dangerous criminal organization ever to strike New Gotham City—and that’s how he wants things to stay! He’ll kill anyone who gets in his way…even the Shredder! ».
