Complete story — includes the ending
Batman investigates Cadmus by interrogating Waller in her own home. As Justice League discuss about Cadmus situation, Project Cadmus members Amanda Waller, Professor Hamilton, General Eiling, Hugo Strange, Tala, and Professor Milo meet to discuss a possible weapon against the League. Due to being demoted to a lower position after a failed experiment destroys the lab, a disgruntled Milo unleashes Doomsday, who kills him and leaves to battle Superman. Batman discovers that Eiling launched a kryptonite missile at Superman's location, and is forced to severely injure himself to save Superman. Superman sends the defeated Doomsday to the Phantom Zone upon being unable to get information about Cadmus from him and Batman later passes judgment on him, noting that Cadmus has a right to be scared of them.
