Naruto's immortality can have a huge impact. He can take more risks in battles involving Gundams. For instance, he could sacrifice himself to save a Gundam pilot knowing he'll come back. His ninja skills like teleportation (body flicker) could be used to quickly move around Gundams during combat, which would be a new and unexpected tactic in the Gundam universe.
Naruto's energetic personality would likely make him a very active pilot. He'd be constantly looking for ways to engage the enemy and wouldn't be afraid to take risks.
Naruto would likely be very curious. He's always up for new challenges and adventures. The Gundam technology with its huge mechs and advanced weaponry would seem like a really cool and powerful thing to him. He might start thinking of ways to combine his ninja skills with the Gundam's capabilities. For example, he could use his speed and agility to pilot the Gundam in a more unique way or use his shadow clone jutsu to confuse the enemies while operating the Gundam. He'd also probably be impressed by the technology that can create such large and powerful machines.
The sharingan ability from Naruto could be integrated into a Gundam x Naruto fanfiction by having a character use it to enhance the Gundam's targeting system. For example, Kakashi could be a Gundam pilot and use his sharingan to quickly analyze enemy movements and weaknesses. The rasengan could also be a part of it. Maybe a character could create a Gundam - sized rasengan as a special attack.
Well, in Devil Gundam fanfiction, rain time can be a turning point in the plot. It could be that during the rain, a secret about the Devil Gundam is revealed. This new information then drives the rest of the story forward, leading to new alliances or conflicts. Also, the rain can make it difficult for characters to carry out their plans, adding an element of struggle to the plot. Say, if they were planning an attack, the rain might disrupt their communication or visibility, forcing them to adapt their strategy.
It might be bright orange, just like Naruto's jumpsuit. It could have the symbol of the Hidden Leaf Village on it too. And for the shape, it could be somewhat streamlined for speed, like Naruto who is always on the move.
If Naruto were to build his own Gundam, he would first need to understand the technology. Since he's a quick learner in the Naruto universe, he could study blueprints. Maybe he'd get help from some tech - savvy characters. He could incorporate ninja - like features into the Gundam, like shuriken launchers or kunai - shooting mechanisms. This would make his Gundam unique and more in line with his ninja style.
First, you need to understand the core elements of both universes. For Gundam Seed, know about the different mobile suits, the political conflicts between the Earth Alliance and ZAFT. In Naruto, study the ninja techniques, the chakra system and the relationships between the villages. Then, find a unique concept to combine them. It could be a character from Naruto ending up in the Gundam Seed world or vice versa.
The dark Gundam cockpit affects Rain in multiple ways. Firstly, it limits his visual perception. He can't fully assess his surroundings, which might lead to wrong decisions. Psychologically, it can create a feeling of unease. The lack of light makes the cockpit seem more menacing. It could also make him more reliant on his other senses, which might not be as well - trained as his sight. And in a story - telling sense, the dark cockpit sets a mood of mystery and danger for Rain's character.
In fanfiction, Naruto learning Juken would be an interesting development. Juken is not just about physical strikes but also about chakra control. Naruto has always been working on his chakra control, and learning Juken would be another step in that journey. It could open up new ways for him to interact with other characters. For example, he might be able to use Juken to help heal allies by manipulating their chakra in a different way. Also, it would make his battles more dynamic as he would have an alternative to his regular ninjutsu and taijutsu moves, and his opponents would have to adapt to this new threat.
Naruto would probably create a Gundam that is bright orange, just like his jumpsuit. It would be really fast and agile, like him. And it might have some kind of special jutsu - powered weapons, like a sword that can cut through anything when charged with chakra.
