“You don’t want to just do a cameo. It’s not a gimmick. I don’t want to have Dr. Manhattan show up for the end of Rebirth, and then he’s in two pages of a book later on,” Johns teased at the recent San Diego Comic-Con. “If there’s one being out there that could mess with time in such a radical way and challenge hope, I just felt like Dr. Manhattan was it.”
