The film would have opened with Darkseid learning of Steppenwolf’s failure and deciding to take matters into his own hands. Using the Boom Tube, Darkseid and his army of Parademons would have invaded Earth, leading to a massive, full-scale battle against the Justice League.

Meanwhile, the League, now fully formed with Superman, Batman, Wonder Woman, The Flash, Aquaman, and Cyborg, would struggle to defend Earth. They would seek alliances, possibly with Green Lanterns, the Amazons, and the Atlanteans, to resist Darkseid’s invasion. However, despite their efforts, Darkseid would prove to be an unstoppable force, overpowering the League and taking control of Earth.

2. Superman Falls to the Anti-Life Equation

One of the most critical elements of Snyder’s plan was the corruption of Superman. After Lois Lane’s tragic death (presumably at the hands of Darkseid or Batman’s failure to protect her), Superman would succumb to the Anti-Life Equation, which Darkseid uses to break his will. With his mind under Darkseid’s control, Superman would become a tyrant, leading the forces of Apokolips in a brutal conquest of Earth.

This moment would mark the fall of the world’s greatest hero and set the stage for the dystopian “Knightmare” timeline that was teased in Batman v Superman and Zack Snyder’s Justice League. Batman, who had been tormented by visions of this future, would realize that his worst fears had come true.

3. The Knightmare Resistance

Following Earth’s devastation, the remaining heroes—Batman, Cyborg, The Flash, Mera, Deathstroke, and possibly others—would form a last-ditch resistance in the Knightmare timeline. This group would operate in a ruined world where Superman, now an enforcer for Darkseid, hunts them down mercilessly.

Batman would be determined to fix everything, and their only hope would lie with The Flash, who had previously appeared in Batman v Superman’s dream sequence, warning Bruce Wayne about Lois. The Flash and Cyborg would develop a plan to use time travel via the Speed Force to send Barry Allen back in time, giving Bruce a chance to prevent Lois’ death and stop Superman from falling to Darkseid’s control.

4. A Race Against Time

As Batman and his team fight for survival, Flash would execute the time-travel plan, sending a warning to Bruce in the past—potentially the same message we saw in BvS (“Lois Lane is the key”). This moment would set up Justice League: Part 3, where the timeline could be altered to prevent Superman’s corruption and ultimately defeat Darkseid before Earth’s destruction.

Themes and Impact

Snyder’s Justice League: Part 2 would have been a dark, apocalyptic, and character-driven film, emphasizing themes of fate, redemption, and sacrifice. The loss of Superman to Darkseid’s will would be one of the most emotionally devastating moments in the DCEU, reinforcing how critical Lois Lane was to keeping Clark grounded in his humanity.

Batman’s arc would have reached its emotional climax, with Bruce willing to sacrifice himself to correct his past mistakes and prevent the dark future he had foreseen. Cyborg and Flash, two of the more underdeveloped heroes in the theatrical version of Justice League, would have had pivotal roles in saving the future.

The film would have likely ended in tragedy, setting up an even greater battle in Justice League: Part 3, where the heroes would have one final chance to restore order.

Conclusion

While Zack Snyder’s Justice League: Part 2 was never made, its intended story was bold, ambitious, and unlike anything seen in the superhero genre. It would have pushed the Justice League into a post-apocalyptic war, given Superman his darkest and most tragic arc, and set the stage for a thrilling time-travel-driven redemption in a third installment.

Snyder’s vision remains one of the most intriguing “what if” scenarios in modern cinema, and while it seems unlikely that it will ever be fully realized, fans continue to discuss and campaign for a continuation of the SnyderVerse.
