Is Kingdom Come next season's CW Arrowverse crossover?

In June DC supervillain Magog will become part of CW/DC's Arrowverse canon, but whether he and/or Kingdom Come, the acclaimed 1996 storyline of his origin, are adapted to the CW TV shows remains to be seen.

DC and Warner Bros. television has made it clear the storyline is set in the canon of the TV shows, the specials are written by creators involved in the shows, and approved by the CW's television show producers. But what they haven't done is given any indication the comic book series will be anything more than a fun print adventure for fans of the shows.

Created by illustrator Alex Ross and writer Mark Waid, Kingdom Come (opens in new tab) is one of DC's most acclaimed and best-selling comic books in its long history.
