>>109245622The 3rd movie, the Legion of Doom, who had been recruiting in the movies between these JL league movies, eventually gets a hold of the contingency plans or hacks brother eye and takes the JL to their limits and eventually destroys the Hall of Justice. Eventually, the damage is done, the Hall of Justice is destroyed and it is considered a lose by the JL. Batman tells the League about the contingency plans and he takes responsibility for this, but he's not remorseful, he feels that it was the right thing to do. After building the Watchtower, the Hall of Justice's replacement, he resigned for the team, feeling that they don't want regulation, SM, feeling the LoD incident was a defeat, expands the JL like wanted to. Batman creates the Outsiders in a different movie as his new team. At the end, we see G. Gordon Godfrey on TV explaining that the JL have become a militaristic power that's a threat to humanity.
4th one would be Amanda Waller and world governments creating Amazo to protect themselves against the JL. Amazo eventually is corrupted by Dr. Ivo. It was also kick off something like a Superhero arms race, which would result in the Justice League of China, that one Russian Superhero team that I don't remember. This would also end up with the creation of the Justice League International and Captain Atom
The last two movies is Darkseid's invasion, Batman returns to help the league, and Darkseid's temporary defeat, he'd be back. After much debate, Batman decided to return to the Justice League
I haven't thought out the last 3 movies much, but my general idea would be the ever growing concern of the prospect of a metahuman population run amok and the conflict that is generated when the world governments see a power they can't fully control. This would also allow for a Kingdom Come movie
