Contstantine is in trouble and Ultraman is ready to rule.
That's the latest two teases from the DC Blog, as Justice League #24 and Justice League Dark #24 show off some unfinished interior art. First, above is a two-page spread from Mikel Janin in JL Dark #24 showing John Constantine fighting "literal inner demons." The issue is J.M. DeMatteis's first as the new writer of the series, and features Constantine as apparently the lone survivor of his magical team, seeking new recruits to fight the otherwordly threat.
Justice League #24's teaser (to your right) focuses on Ultraman, as drawn by Ivan Reis and Joe Prado. The issue promises to reveal a secret motivation for the Superman of Earth-3, and the evil backwards kryptonian sure looks menacing here.
