Change is constant, but family is forever...at least it's supposed to be. Since recent events have left his family fractured, Donatello has taken it upon himself to do whatever it takes to protect his brothers from a threat only he saw coming. Little does he know it's already too late...Armageddon is inevitable. It's a race against time in one of the biggest TMNT stories yet!
