Taking place in the New Justice relaunch, the story appeared in nine issues spread across five comic titles published over five weeks in December 2020.
At a panel discussion during the October 2020 New York Comic Con, writer Ron Marz said the story came together around "Justice League Viking", a 10th-century version of the modern superhero team.
[5] In the distant past, there was a man named Edwald Olaffson who developed ice powers after saving his son from a polar bear attack in Greenland in the 10th century.
In the 10th century, Hippolyta, Swamp Thing, and Viking Prince free Black Adam to deal with the Frost King when he threatens to destroy the world.
In the present, the Justice League (Batman, Superman, Wonder Woman, Flash, Green Lantern, Martian Manhunter, and Aquaman) thwarts an attempted bank robbery by Multiplex, Icicle, and Catman.
[7] In the present, Jimmy Olsen and Lois Lane are about to be killed by ice monsters on top of the Daily Planet building when Superman saves them.
Donna Troy realizes the Frost King is the story that Hippolyta told her when she was in Themiscyra and tells Cyborg to teleport her and Flash there to help the Amazons.
In the aftermath, Sebastian Stagg is arrested, the Viking Prince returns to the afterlife, Swamp Thing finds a new avatar, and Superman rebuilds the Fortress.
Bleeding Cool criticized it for not revealing new information nor moving the plot along, and found it lackluster compared to previous work by the writers and art team.
