How about a crossover with a post - apocalyptic world? Survivors from a desolate future find a way to the Roman Empire time. They could introduce advanced technology concepts that are primitive by their standards but seem like magic to the Romans. And they might also learn about the Roman society's strong values and governance systems which could be used to rebuild their own world.
Well, a great plot for a Naruto and Empire crossover fanfiction could be that the Nine - Tailed Fox within Naruto has some connection to a powerful and ancient beast in the Empire's lore. As Naruto tries to control his power, he discovers this link and has to work with the Empire's scholars and warriors to either tame the beast again or use its power for good. For example, if the Empire is under threat from a dark magic - using enemy, Naruto's unique chakra and the power of the beast could be the key to victory.
One idea could be to cross two different empires from different fictional universes, like the Galactic Empire from Star Wars and the Imperium of Man from Warhammer 40,000. You could explore how their military strategies and technologies interact. Maybe the Stormtroopers of the Galactic Empire meet the Space Marines of the Imperium. Another idea is to cross an ancient historical empire, such as the Roman Empire, with a modern - day fictional empire. This could lead to a story about cultural clashes and the adaptation of old - world values in a new setting.
One idea could be a story where the political intrigue of the Roman Senate is mirrored in the power struggles of the Great Houses in Westeros. For example, the patrician families in Rome could be compared to the noble houses in Game of Thrones, with similar backstabbing and alliances for power.
One plot idea could be Roman Torchwick getting transported to a different universe, like a modern-day Earth. He could use his skills to try and take over the criminal underworld there. Another could be a crossover with a superhero universe, where he teams up with a villain from that world to cause chaos. Maybe he could also cross over into a fantasy realm and try to steal magical artifacts.
One idea could be a power struggle within the empire. Maybe a young noble rises to challenge the established ruling class. Another could be an exploration of the empire's relationship with a mysterious alien race. It could lead to a story of cooperation or conflict.
Perhaps a 'Game of Thrones Roman Fanfiction' could involve a character from Rome being magically transported to Westeros. This Roman could introduce new ideas such as Roman architecture, building great amphitheaters in the Seven Kingdoms. They could also bring their religious beliefs and clash or blend with the existing faiths in Westeros. This would create a whole new dynamic of cultural exchange and conflict within the world of Game of Thrones.
A third idea could be a crossover with a dystopian empire. The shinobi would face a much harsher and more controlling regime. This could lead to some really intense storylines as they try to either overthrow the regime or find a way to co - exist within it.
Cleopatra is another great character. Her beauty and intelligence made her a very influential figure. In a crossover, she could use her charm and wits to manipulate characters from different settings. Say, if it's a crossover with a superhero world, she might try to enlist the help of the superheroes for her own political gain.
One idea could be exploring the backstories of the secondary characters more in - depth. For example, what was the life of the mechanic before joining the Atlantis expedition? Another could be a story where the Atlanteans start to rebuild their civilization above ground, facing new challenges. Maybe a third idea could be a time - travel fanfic where modern characters go back to the prime of Atlantis and see how their technology and culture were at their peak.
One idea could be exploring the rise of a new, unexpected power within the Dragon Age empire. Maybe a group of mages and templars form an alliance to combat a common threat that the empire has ignored. This could lead to a lot of political intrigue and power struggles.
