A series titled after these two characters began in 2007, with writing by Judd Winick and art by Cliff Chiang. These characters first met in Justice League of America #74, in which Larry, the husband of one of them, sacrificed himself to save the other.
These characters briefly moved to Seattle and opened a flowershop, and one of these characters killed Everyman while he was impersonating the other during their "Wedding Special".
Name the romantic pairing one with a supersonic screaming martial artist and the other with an emerald archer?
Hint 1: One of these characters is usually shown in fishnet stockings and a leather jacket, and the other as a businessman in Star City.
