After the events of 'The Flash: Chaos Effect' ended, Barry Allen believed that the problems he had caused had all been reversed, and indeed they had been. However, the destabilization of the Multiverse at that time also ended up awakening something capable of doing much worse damage than messing up worlds - and yes, destroying them. Now, the Justice League finds itself joining forces with allies from other corners, in conjunction with another awakened force, if they are to stand any chance of stopping a carnage of unimaginable proportions. This is not a confrontation, much less a war. This is a Crisis the Multiverse has never witnessed before. 6th film of the title team in this universe, 'Justice League: Crisis on Infinite Earths' ends the so-called Phase 7, the last of the so-called Earth-225.
