In the time of the JSA a villain by the name of Baron Blitzkrieg breaks into the Museum of Natural History being perused by Wild Cat but when the Baron finds what he is looking for an artifact known as the heart of darkness he throughs it on the floor breaking it and unleashing the all-powerful Eclipso who then instantly killed Blitzkrieg and Wild Cat but before his last breath Wild Cat sent out a warning to the JSA just saying Eclipso is here... The next day Wild Cats body is taken to scientist Dan Garret also known as Blue Beetle who after getting the message from his teammate needed to investigate but he couldn't figure it out, so he took his finding to the more mystical members of the team after Dr Fate states that "We have been warned about him"(at the team a very ambiguous statement that will be revealed in the next Justice League movie), Kent nelson said he has done much research on Eclipso and found out his weakness to sunlight so they devise a plan to keep him distracted long enough until the sun rises and then trap him in a new and improved Heart of Darkness Called the Black Crystal which the plan thankfully succeeds. In the end the JSA disbands and agree to only reform if absolutely necessary. In the post credit scene, we see Klarion Stealing the Black Crystal and talking to Vandal Savage who makes a vow to kill all superheroes and become the tyrant he once was all over again in this life or the next.
