Plot Doomsday Clock is the finale of the story that was established in
DC Rebirth, officially concluding the storylines that began in
the New 52 continuity. The comic features the concept of the
Multiverse, where the
Watchmen universe exists separately from the
DC Universe and each universe's characters treat the other universe's characters as fictional. In the
Watchmen universe, seven years after the massacre in New York City, the details inside
Rorschach's journal have been published, exposing
Ozymandias's role in the event. Now a fugitive, Ozymandias gathers several others to find
Doctor Manhattan and bring him back to save the world. Reggie Long, the new Rorschach, attempts to enlist the help of
Batman, while Ozymandias consults
Lex Luthor. Meanwhile, in the DC Universe, during the
present day, the Supermen Theory, a conspiracy theory that accuses the
federal government of the United States of creating its own
metahumans, has created international conflict and led to an
arms race, with various governments around the world recruiting metahumans and creating sanctioned superteams. Dr. Manhattan, who is thought to have deliberately manipulated the post-
Flashpoint universe, has a vision of the future in which he believes he and
Superman will try to kill each other.
