The publisher has hinted that the mysterious Pandora character - who appears in the background of all 52 of its #1 issues - is the daughter of Darkseid.
A preview posted on USA Today revealed that the villainous New God's purpose on Earth was to find his missing offspring.
A conversation is overheard in which Superman is identified as "one who will prove vital in the search for the daughter of Darkseid".
The hooded figure debuted in the final issue of Flashpoint, which initiated DC's September relaunch.
DC later identified her as Pandora and promised that more would be revealed about her in Geoff Johns and Jim Lee's Justice League.
Darkseid is the chief villain of the first arc of the title, and will apparently also have a role in the forthcoming Earth 2.
The evil New God had several sons in the previous continuity, but never a daughter.
