DC announced the actual title to "Brightest Day Aftermath: The Search" via their blog.
If you haven’t read BRIGHTEST DAY #23 and haven’t seen any of the press coverage about the big reveal, you might want to stop reading here. A few weeks back, we announced a new miniseries called BRIGHTEST DAY AFTERMATH: THE SEARCH, written by Jonathan Vankin and drawn by Marco Castiello. Today we can announce the book’s actual title: BRIGHTEST DAY AFTERMATH: THE SEARCH FOR SWAMP THING.
As for who that blacked out figure is, we can’t say … yet.
