“Trinity War” is upon us!

Tomorrow, the comic book event of the summer kicks off in JUSTICE LEAGUE #22. What happens when the Justice League, the Justice League of America and the Justice League Dark all go into battle with one another? Who's who in the Justice League?

You have questions – and we have some answers from the man behind “Trinity War” – Geoff Johns!

DC Entertainment's Chief Creative Officer and the writer of JUSTICE LEAGUE and JUSTICE LEAGUE OF AMERICA breaks down the basics on “Trinity War,” the three Justice Leagues and how this summer's epic event leads into September's villain-centric FOREVER EVIL in this exclusive animation clip (which IGN exclusively debuted earlier this afternoon). The video serves as the definitive crash course on all things Justice League, “Trinity War” and The New 52 before you head to comic shops tomorrow to pick up part one of “Trinity War.”
