Because of the word 'trinity,' there's a lot of things in threes involved. The first thought many had was it would involve DC' Trinity of Superman, Batman and Wonder Woman. The FCBD issue also introduced the idea of the Trinity of Sin consisting of Pandora, Phantom Stranger and the Question. Another trio involved will be three different teams - the Justice League, the Justice League of America and Justice League Dark.
The crossover story will run through six issues the three Justice League titles in July and August. It all begins in JUSTICE LEAGUE #22 written by Geoff Johns with art by Ivan Reis and Joe Prado. JUSTICE LEAGUE OF AMERICA will be co-written by Johns and Jeff Lemire with art by Doug Mahnke (which Mahnke did hint in our video interview that he'd be working with Johns again). JUSTICE LEAGUE DARK will be written by Lemire as well.
Geoff Johns told USA Today the following:
"We really want to find and carve out the Justice League corner of the DC Universe. It is a universe all itself with these three teams, and it feels big enough to be worthy of a Justice League story.
It's going to be really interesting when these characters do come together, because some of them haven't met, some of them have, and what happens and unfolds in this is going to force them to choose sides."
There will be plenty of tension as we'll see more on the relationship between Superman and Wonder Woman and Steve Trevor's reaction as well as some conflict between Constantine and Zatanna. Of course the involvement of the Trinity of Sin will also complicate things. Pandora was on hand for the creation of this DC Universe at the end of Flashpoint and we know there's something going on with her box she liberated in the FCBD issue. Shazam will also finally meet up with the others and Johns mentions while he won't have an allegiance to anybody, he will "come into conflict with Superman in a very big way."
Readers shouldn't simply dismiss this as a two month event in the three titles. Johns also teased that this will affect the DCU.
"It's not going to end wrapped up in a bow. Something really, really major happens that kicks off some pretty crazy stuff at the end of August."
We'll have to wait for July for the action to begin.
