Well, one possible plot could be that Naruto somehow gets transported to the Mario universe where he meets Rosalina. They could start off as strangers, but then Naruto's determination and kindness draw Rosalina's interest. Maybe they team up to face a common threat that is endangering both the ninja world and the Mario universe.
A 'waluigi x rosalina fanfiction' could be about exploring an unexpected relationship between the two characters. It might involve how their different personalities interact. For example, Waluigi is often portrayed as a bit of a mischievous character, while Rosalina has a more serene and maternal quality. In the fanfiction, the writer could create scenarios where Waluigi tries to impress Rosalina in his own clumsy way, or Rosalina helps Waluigi to become a better version of himself. It could also be set in different locations within the Mario universe, like on Rosalina's Comet Observatory or in one of the many kingdoms that Waluigi has visited during his adventures.
Another theme is friendship. Given that they are from different universes, the development of a friendship between them is often a central part of the story. They start off as strangers, but as they face challenges together, they grow closer. For instance, in some fanfictions, they help each other out in battles against common enemies that threaten both of their worlds.
Well, I found a fanfiction titled 'Naruto and Rosalina: An Unlikely Alliance'. It's quite fascinating as it delves into how two characters from completely different universes, Naruto from the shinobi world and Rosalina from the Mario - related cosmos, form a bond and work together against a common threat that somehow spans across their worlds.
Well, clearly Mario and Rosalina are the main characters. Mario is the well - known plumber hero who is always ready to save the day. Rosalina, on the other hand, is the guardian of the cosmos. She has a deep connection with the stars and galaxies. In fanfiction, their personalities often interact in unique ways, with Mario's down - to - earth nature (despite his fantastical adventures) contrasting with Rosalina's more ethereal and celestial presence.
One common theme is friendship. Writers often explore how Peach and Rosalina, who come from different parts of the Mario universe, form a strong bond. Another theme is adventure. They might go on quests together, like searching for a lost power star. And of course, there's the theme of discovery, whether it's Rosalina introducing Peach to new parts of the galaxy or Peach showing Rosalina the joys of the Mushroom Kingdom.
There are quite a few. Some might focus on adventure scenarios where Luigi and Rosalina team up and gradually develop feelings for each other. Others could be more about a budding romance in the Mushroom Kingdom, exploring their personalities and how they interact in different situations.
One possible theme could be redemption. Waluigi is often seen as a bit of a villain or a troublemaker. Through his relationship with Rosalina, he could be on a path to redemption. Another theme could be the power of love to change people. Rosalina's kind nature might influence Waluigi to be a better character.
Naruto would probably be his usual energetic self, trying to figure out who Rosalina is. Rosalina, being a more calm and mysterious character, would be a bit reserved at first. But Naruto's positive attitude might make her open up. They could start by just sharing their stories, Naruto about his ninja training and Rosalina about her duties in the cosmos.
