Well, in 'Code Geass Time Travel Fix It Fanfic', a cool concept might be the butterfly effect. When a character time travels, even the smallest change they make can have huge consequences. It could be something as simple as saving a single person who then goes on to change the course of an entire battle. Also, there could be the idea of self - discovery through time travel. A character might learn more about their own powers or purpose in life by going back and reliving certain events. And then there's the concept of rewriting history to create a better future for everyone, not just the main characters.
One interesting concept could be how the time travel affects the existing power dynamics in the Code Geass universe. For example, if Lelouch were to travel back in time, he might use his knowledge of future events to gain an even greater advantage over Britannia. Another concept could be the alteration of character relationships. Maybe characters who were enemies in the original timeline could become allies due to the changes brought about by time travel.
Some interesting concepts in 'Code Geass Sequel Fanfic' could include new character backstories. For instance, we could learn more about the minor characters from the original series and how their pasts shape their actions in the sequel. There might also be the concept of a hidden Geass order or organization that was not known before. This could add an element of mystery and conspiracy to the story. Additionally, the exploration of cultural differences between the different regions in the Code Geass universe could be fascinating. How do the cultures interact and influence each other? It could lead to interesting plotlines about diplomacy and cultural exchange.
Another concept could be the expansion of the world - politically and socially. The fanfic might delve deeper into the relationships between different countries and factions. It could show how the power dynamics shift after the events of the original series and how new alliances are formed or old ones are broken.
One interesting concept could be alternate endings for the characters. Maybe in the fanfic, Lelouch has a different fate than in the original series, like instead of his sacrificial end, he manages to find a way to rule Britannia without all the bloodshed. Another concept could be new Geass powers. For example, a character might develop a Geass that can control technology rather than just people.
Lelouch would be a likely candidate. He has a strong sense of justice and a desire to change the world. Given his intelligence and strategic mind, if he were to discover the means of time travel, he would likely use it to correct the many wrongs in the Code Geass world, such as the oppression of Britannia. He could go back in time to prevent his mother's death and change the course of his own life and the fate of the world.
In 'harry potter time travel fix it fanfic', a really cool concept is fixing the whole prophecy situation. Time travel could be used to change how the prophecy was heard or interpreted. This might prevent Voldemort from targeting Harry in the first place. Also, the idea of using time travel to save Remus Lupin is interesting. He had a tough life and died in the Battle of Hogwarts. The fanfic could use time travel to give him a better ending, like finding a cure for his werewolf condition.
Some fanfictions in 'Code Geass the Gamer' might explore the idea of in - game items or loot. The characters could find or earn items that give them an edge in the Code Geass world, such as a device that temporarily enhances their Geass range or a charm that protects them from mind - control attacks.
A crossover might involve characters from different universes coming into the Code Geass world. Say, a character with superpowers from a superhero - themed anime enters the story. This could create a lot of chaos as Lelouch tries to either use this new element to his advantage in his fight against Britannia or has to deal with the unforeseen consequences of this new presence.
The idea of time travel as a form of spiritual journey could be explored. In the Hobbit universe, time travel might not just be about physically moving through time but also about the hobbits connecting with their ancestors on a deeper, spiritual level. For example, a hobbit could travel back in time and meet an ancient hobbit sage who imparts wisdom that is crucial for the future of the Shire. This would blend the fantastical element of time travel with the rich cultural and spiritual aspects of the hobbits' world.
A plot could involve Suzaku traveling back in time after all the destruction in the original timeline. He realizes that his loyalty to Britannia might have been misplaced. So, he teams up with Lelouch from an earlier time and they work together to change the world for the better, using their combined skills and knowledge from different points in the timeline.
