A cool 'injustice crossover fanfic' could involve 'Injustice' and the 'Watchmen' universe. The gritty and morally complex world of 'Injustice' would contrast well with the unique and dark 'Watchmen' universe. Rorschach could find himself in the 'Injustice' universe and his uncompromising view of justice might clash with some of the characters there, while Dr. Manhattan's god - like powers could be a major factor in the story, either as a threat or an unexpected ally.
How about a crossover with the 'Watchmen' universe? The complex and morally - gray characters from 'Watchmen' would fit well into the 'Injustice' world. Rorschach's unwavering sense of justice, no matter how extreme, could either clash or find common ground with the characters in 'Injustice'. It would be a great exploration of different concepts of right and wrong in a superhero - filled world.
One idea could be exploring an alternate ending where the heroes and villains form an uneasy truce much earlier. This would change the power dynamics in the Injustice universe significantly. Another idea is to focus on a minor character's perspective during the major events, like a civilian caught in the crossfire.
A good plot for Injustice Gods Among Us crossover fanfiction could be a time - travel - based crossover. Maybe a character from Injustice accidentally travels to a different timeline in the DC universe where things are much more peaceful. This character would then have to adapt to this new world and its heroes and villains. Or perhaps characters from different eras of DC, like Golden Age heroes, cross over into the Injustice universe. They would be shocked by the state of the world and try to bring back the old values of justice. They could team up with some of the Injustice characters who still hold onto those ideals.
One idea could be exploring what would happen if a hero from the Marvel universe was wrongly accused of a crime in the Injustice world. For example, Spider - Man being framed for a mass destruction event. Another could be a story about how the X - Men would deal with the unjust laws in the Injustice setting. Maybe they would form an alliance with some of the Injustice heroes to fight for mutant rights within that corrupted system.
An interesting Injustice OC fanfiction could center around an OC who is a time - traveler. This character could go back in time to try and prevent the events that led to the Injustice storyline. They would face challenges like not changing too much of the timeline while still trying to stop the chaos.
You could do a crossover within different fable universes. For instance, take the moral - driven characters from Aesop's fables and put them in the world of Native American fables. The animals in Aesop's fables might learn new values from the Native American fable characters. Also, consider mixing fables from different cultures, like Asian fables and European fables, in a fanfic.
Maybe a crossover with a fantasy world where the Darkness entities interact with magical creatures. For example, they could form alliances or rivalries with elves or wizards, which would lead to a whole new set of adventures and conflicts.
A uzumaki crossover fanfic could involve crossing over with 'Bleach'. Picture an Uzumaki character in the Soul Society, their strong chakra being mistaken for reiatsu. They could bring new fighting styles and techniques to the Bleach universe.
One idea could be a crossover with 'Naruto'. Gon could meet Naruto and they could have a friendly competition in terms of strength and speed. Another idea is a crossover with 'One Piece', where the Hunters from 'HxH' join the Straw Hat Pirates on an adventure. Maybe they could be searching for a rare treasure that has both the allure of the Grand Line and the mystery of the 'HxH' world.
One idea could be a Dalek crossover with the Doctor Who companions. Imagine the Daleks facing off against a group of companions who have to use their unique skills and knowledge to outwit the Daleks. Another could be a crossover with a science - fiction adventure like Star Trek. The Daleks' aggressive nature would contrast greatly with the more diplomatic Starfleet.
