Fanfiction ideas combining Justice League and Avengers: Endgame
Another possibility is a post - Endgame fanfiction. After the events of Endgame, the Avengers discover a new threat that has ties to the Justice League's world. Maybe a powerful villain from the DC universe has somehow been awakened by the events in the Marvel universe. So they have to reach out to the Justice League for help and together they figure out a way to stop this new threat.
A different take could be a crossover during the time - travel parts of Endgame. The Avengers travel to different points in time, but accidentally end up in the DC universe's past. There they meet the predecessors of the Justice League. They have to work together without disrupting the timeline too much while also finding a way back to their own universe to complete their mission.
Fanfiction ideas combining Avengers, Justice League and Power Rangers
A fanfiction could focus on a character from each group being transported to a strange new dimension. For example, Iron Man from the Avengers, Batman from the Justice League and the Red Ranger from Power Rangers. They must work together to find a way back home while also dealing with the threats in this new world. This would allow for interesting character interactions as they come from very different backgrounds.
Fanfic ideas combining Avengers, Justice League and Mother Box
Another fanfic could be about a young inventor who discovers a Mother Box and accidentally activates it, which sends out a signal that attracts both the Avengers and the Justice League. The two groups initially think the other is trying to steal the box, leading to some tense confrontations. But then they figure out that there's a greater threat emerging because of the box's activation, so they join forces.
Fanfiction ideas combining Naruto, Shinju, and Justice League
One idea could be that the Shinju's power somehow connects the Naruto universe and the Justice League's universe. Maybe the Shinju's energy creates a rift, and Naruto characters end up in the Justice League's world. They could team up to fight a common enemy that is attracted by the strange energy of the Shinju. For example, a powerful demon from Naruto's world could be drawn to the new universe and the Justice League, with their high - tech and superpowers, join forces with Naruto and his friends who have ninja skills and chakra abilities.
Fanfiction ideas combining Dragon Ball and Justice League
One idea could be a crossover where Goku is accidentally transported to the Justice League's universe.

They could team up to fight a common enemy like Darkseid who has somehow acquired the Dragon Balls and is using them for his evil plans.
Fanfiction ideas combining Iron Man and Justice League
One idea could be that Iron Man's technology gets mixed up with Justice League's alien tech. Maybe he creates a new suit using some of the Kryptonian crystal technology he discovers while working with Superman. This new suit gives him powers similar to Superman for a short time, but it also has some unexpected glitches that lead to humorous or dangerous situations.
How would the characters interact in a Justice League and Avengers: Endgame fanfiction?

Fanfiction ideas combining Naruto's Rinnegan and the Justice League
One idea could be that a character from the Naruto universe with the Rinnegan somehow gets transported to the DC universe where the Justice League exists.

For example, using the Rinnegan's abilities like the Six Paths powers to combat a powerful villain like Darkseid.

Fanfic Ideas Combining Harry Potter and Justice League
Another concept is that the magic from the Harry Potter series starts to seep into the DC universe where the Justice League operates. This causes chaos as the laws of physics in the DC world are disrupted. The Justice League has to seek help from Hogwarts professors to understand and contain this new form of magic energy. Superman might be intrigued by the idea of magic being a new power source or a new threat he can't easily overcome with his super strength.
Fanfiction ideas combining Harry Potter, Silent Hill and Justice League

The wizards can use their spells and the League can use their superpowers to fend off the encroaching darkness.
