In this fanfiction, it might start with Jaune as a baby being found by the dragon. As he grows, the dragon imparts its wisdom on him, like ancient languages or secrets of the land. Jaune could also have a special bond with the dragon that allows them to communicate telepathically. His journey could be about finding his place in the world, whether it's among the dragons or with the humans. He might also discover that he has a special mission, something that only he, with his unique upbringing, can achieve.
Maybe there are other magical creatures. Like a friendly sprite that befriends Jaune and helps him understand the more delicate aspects of the magical world that the dragon might not be so good at explaining. There could also be an evil sorcerer who wants to capture Jaune because of his unique connection to the dragon, thinking he can use it for his own dark purposes.
One possible plot could be that Naruto is somehow transported to the RWBY universe and takes on the role of Jaune. He then uses his ninja skills to help Jaune's team in battles and they are all amazed by his abilities.
One possible plot could be that Natsu, while being raised by the female dragon, learns unique dragon magic that is different from what he would have learned otherwise. He might develop a special bond with the dragon, like a mother - son relationship, and the story could follow his adventures as he uses the skills taught by the dragon to protect the dragon's lair or the surrounding area from threats.
One possible plot could be that Natsu is raised by a dragon other than Igneel. This new dragon might have different values and teachings. For example, if it was a more reclusive dragon, Natsu might be less outgoing and more reserved compared to his canon self. The dragon could also teach Natsu different types of magic, which would change the way he fights and interacts with others in the Fairy Tail guild.
One common plotline could be Jaune having unique training methods. For example, in some fanfictions, he might be trained by a hermit - like figure who imparts special combat skills. Another could be his relationships evolving differently. Maybe he forms closer bonds with certain characters earlier than in the original series due to the altered upbringing in the fan - made scenarios.
It could be that Jaune has some sort of traumatic past experience with funus, which makes him scared. Maybe he witnessed its destructive power or had a personal encounter that left him with deep - seated fear.
One possible plot could be that Jaune discovers he has a daughter in a very unexpected way. Maybe she shows up at Beacon Academy one day, and he has to figure out how she came to be. He then has to balance his duties as a Huntsman with being a father, all while protecting her from the various threats in the RWBY world.
Well, perhaps the plot could involve Jaune trying to train the pet Grimm. He might face challenges from other characters who are against having a Grimm as a pet due to their inherently dangerous nature.
Well, it could involve Jaune using Jedi-like powers in the RWBY universe. Maybe he discovers an ancient relic that gives him the Force and he has to learn to control it while still dealing with the Grimm and his normal RWBY duties.
One possible plot idea could be their journey of building a life together. They might face challenges from their different backgrounds. For example, Winter's strict military upbringing and Jaune's more laid - back nature could lead to some comical and also touching moments as they learn to understand and adapt to each other.
