The story involves the Justice League facing a massive threat from Apokolips. Darkseid and his forces bring chaos and destruction. The heroes have to fight against overwhelming odds, with many of them facing personal challenges and sacrifices along the way.
Some of the main characters are Superman, Batman, Wonder Woman, and Darkseid. There are also characters from the Justice League Dark like John Constantine.
Zatanna also plays a significant role. Her powerful magic skills are essential for combating the dark forces of Apokolips. She can perform spells that can turn the tide of battle, whether it's for defense or offense.
One interesting plot twist could be a character who was thought to be a villain actually turns out to be a key ally in the fight against Apokolips. Maybe they were under some sort of mind control before.
Well, to determine if JL 50 is a real story, we need to look at its source, the details presented, and any available background information. But as of now, with just the name, it's impossible to tell.
