In Gundam Seed Crossover Fanfic, a great concept is the fusion of different factions. Imagine the Earth Alliance and ZAFT having to team up against a new common enemy. This would change the whole power dynamic and the relationships between characters. Also, the idea of pilots from different series swapping Gundams can create really exciting scenarios, with each pilot having to adapt to a new machine's capabilities.
One interesting concept could be the crossover of Gundam Seed with other mecha universes. For example, combining the technology and characters from Gundam Seed with those from Macross. This could lead to unique storylines where the pilots have to adapt to different combat styles and technologies. Another concept might be a crossover with a fantasy world, like having Gundam Seed characters enter a world full of magic and mythical creatures. They would have to use their mecha skills in a completely different environment.
Another concept is the backstories of OCs. In Gundam Seed OC fanfiction, we often see OCs with complex pasts, like being from a colony with a unique culture that has been oppressed. Their fight in the story then becomes not just about the overarching war in Gundam Seed, but also about the liberation of their own people.
One interesting concept could be alternate endings. For example, a fanfiction might explore what would happen if Kira Yamato made different choices during key battles. Another concept could be character development that was not fully explored in the original. Maybe a side character gets more depth and a new backstory in the fanfiction.
One interesting concept could be the combination of different Gundam universes' technologies. For example, seeing the mechanics from the original Gundam series combined with those from Gundam Wing. It creates unique and powerful mobile suits that haven't been seen before in the official lore.
One idea could be that Naruto characters possess Gundam mobile suits. For example, Naruto could pilot a Gundam with his signature orange color and use his chakra to power up the suit's special abilities. Sasuke might have a more stealth - based Gundam, using his Sharingan to enhance the suit's targeting systems.
One idea could be a crossover with another mecha anime like Macross. The characters from Gundam Seed Destiny could find themselves in the middle of a space battle in the Macross universe, having to adapt to the different technology and combat styles. For example, they might encounter the transforming Valkyrie mechs and have to figure out how to fight against them or even team up with the Macross pilots.
Some Gundam Seed fanfictions center around the backstories of minor characters. They give more depth to those characters that we might not have seen much in the original series. For instance, a fanfiction about the pilots of the GINN suits in ZAFT. It could explore their training, their hopes, and how they view the war. And then there are fanfictions that rewrite the whole plot, starting from a different premise, like if the Coordinators and Naturals had a more peaceful coexistence from the beginning and how that would change the story.
Well, some Gundam Seed fanfics deal with alternate universes. In these, the events of the original series are completely changed. For instance, the Coordinators and Naturals might have found a way to co - exist peacefully from the start, and the story could be about how they build a new society together. Some fanfics also center around the love stories of the characters. They might develop the relationship between Lacus and Kira in more depth, adding more romantic and emotional elements to their story.
One interesting concept could be the fusion of the Gundam Wing universe's mecha technology with the magical elements from the Potter world. For example, how would a wizard pilot a Gundam? Maybe they could use magic to enhance the Gundam's abilities or to create new types of attacks. Another concept might be the interaction between the different characters from both universes. How would Heero Yuy react to meeting Harry Potter? Would they become allies or enemies? And also, the idea of using the Gundam Wing mobile suits in the wizarding world's battles against dark forces could be really exciting.
To write a good Gundam Seed Crossover Fanfic, you need to do in - depth research on both Gundam Seed and the other element you're crossing it with. For example, if it's another mecha anime, study the mecha designs, the power systems, and the cultural backgrounds of both. When writing, focus on building a strong narrative arc. Start with an engaging hook, develop the conflict gradually, and resolve it in a satisfying way. Don't forget to add some emotional depth to the characters, especially when they face new challenges in the crossover.
