The New 52
In addition to "Villains Month", a seven-issue limited series titled "Forever Evil", by Geoff Johns and David Finch, launched in September 2013 and focused on the Crime Syndicate, an evil version of the Justice League from Earth-3 in the Multiverse, as they attempt to take over Prime Earth in the Justice Leagues' defeat at the end of "Trinity War". The "Forever Evil" event ran in other titles starting in October 2013, including three 6-issue tie-in books that launched: "Forever Evil: Rogues Rebellion" by Brian Buccellato and Patrick Zircher; "Forever Evil: Arkham War" by Peter Tomasi, Scot Eaton and Jaime Mendoza; and "Forever Evil: A.R.G.U.S." by Matt Kindt and Manuel Garcia. Other tie-in titles included: "Teen Titans", "Suicide Squad", "Justice League", "Justice League of America" and the "Forever Evil: Blight" storyline in "Constantine", "Justice League Dark", "Trinity of Sin: Pandora", and "Trinity of Sin: The Phantom Stranger". "Forever Evil" #1 was also reprinted in a director's cut one-shot in October 2013.
Forever Evil: Blight
"Constantine" #10 received a 3 out of 10 from Newsarama's Rob McMonigal. He said, "The NuJustice League Dark team travels to Heaven but the story is stuck in limbo as this Forever Evil crossover feels very much like filler. This is exactly what fans feared when John moved to the mainstream DCU, with Constantine stuck participating in things that even he doesn’t want to do, as dialogued by Ray Fawkes. This felt like a way to introduce the new anti-heroes to an unfamiliar reader picking up a tie-in, with pages spent having “God” explain their nature to an uncaring Constantine. Guest artist Beni Lobel misses a chance to make it visually interesting, opting for a realistic style in a supernatural environment. The art is technically perfect, but lacks punch or impact, making this an issue readers should probably skip." Issue 11 received a 7.8 out of 10 from IGN's Jesse Schedeen, saying, "At the end of the day, "Forever Evil: Blight" is really a John Constantine story, and never is that fact more obvious than within Constantine's own book. But that's hardly a bad thing. It's been an uphill battle for DC to reestablish Constantine as a DC Universe character rather than a Vertigo one, but Blight has helped in that process. "Constantine" #11 in particular does a great job of illustrating who Constantine is, how he thinks and feels and suffers, and how he relates to the many other mystical heroes and villains of the DCU. On that basis alone, it's easy enough to forgive this crossover its faults."
