In the fanfic, it could start with Naruto being hunted by a group of powerful ninja - like villains in his own world. They manage to corner him and are about to finish him off when Rogue suddenly appears. She uses her powers to fend off the villains and saves Naruto. Naruto is initially cautious of her but soon realizes she means no harm. They then start a journey together, with Rogue teaching Naruto some things about her world and powers, and Naruto sharing his ninja knowledge. Eventually, they face a greater threat that requires both their skills and powers to defeat.
One possible plot could be that Naruto is on a mission in his world and gets caught in a powerful jutsu that sends him to the X - Men's universe. There, he's in danger as he doesn't understand this new world. Rogue senses his distress and saves him from some immediate threats like angry mobs who are scared of his strange appearance. Then they start to communicate, with Naruto trying to explain his situation using hand signs and simple words, and Rogue trying to understand and help him get back home.
I'm not sure if there is a very specific, well - known fanfic with this exact title. However, in general, it could be an interesting crossover concept. Naruto is from a world of ninjas with his own set of powers and skills, and the X - Men have their mutant abilities. If in this fanfic, Rogue saves little Naruto, perhaps it could involve Rogue using her power - absorbing abilities to protect Naruto from some kind of threat in his world or in a combined universe. It might also explore how Naruto's ninja training and determination could interact with the X - Men's way of handling things.
Well, it could be that Rogue has been causing some minor chaos due to her power - absorbing abilities without really meaning to. The X - Men notice her and decide she'd be better off with them. They send someone like Wolverine to approach her. He can relate to her in a way as he's also a bit of an outsider. They then train her to control her powers and she becomes an important part of the team, perhaps helping them in a big battle against a common enemy.
In a 'naruto goes rogue' fanfic, the plot could involve Naruto feeling betrayed by the Hidden Leaf Village. Maybe he discovers some dark secrets about the village leaders. For example, he might find out they were using him all along. So, he decides to break away and form his own group of outcasts who also felt wronged by the village.
Well, in a Rogue Titan x Levi fanfic, the plot could start with the Rogue Titan being a mystery. Levi is assigned to figure out what this Rogue Titan is all about. As he gets closer to it, he realizes that the Titan has a level of intelligence that he didn't expect. The Rogue Titan, in turn, seems to recognize Levi in some way. Their relationship could be a slow - burn one, where they gradually learn to trust each other. Along the way, they might face challenges from the military leadership who don't trust the Rogue Titan. And there could be a big reveal at the end about the true nature of the Rogue Titan and how it ties into the overall story of Attack on Titan, like maybe it's a key to unlocking a new power or a secret about the Titans' origin.
One way their worlds could collide is through a cross - dimensional rift. Maybe Naruto is on a mission and accidentally gets sucked into the X - Men's universe. Rogue, being the curious and empathetic character she is, might be the first to approach Naruto. She could be intrigued by his unique chakra powers. Naruto, on the other hand, would be completely bewildered by this new world full of mutants with strange abilities.
A great plot could be a time - travel fanfic. Rogue and Sabertooth get sent back in time to an era when mutants were first emerging. They have to deal with the primitive understanding of mutants at that time and also try not to change the future too much. Or perhaps a story where Sabertooth is injured and Rogue has to use her powers to save him in a way that doesn't harm herself, leading to a new understanding between them.
In a 'naruto becomes a rogue ninja fanfic', it could start with Naruto being ostracized by the village due to his growing power which some elders fear. They try to suppress him, and Naruto, feeling betrayed, decides to leave and become a rogue ninja. He then might go on a journey to find a new place where he can be accepted for who he is, and along the way, he could meet new allies and enemies alike. He may also develop new jutsu away from the traditional teachings of the village.
The plot could involve Naruto characters being transported to the X - Men world or vice versa. They might team up to face a common threat that is affecting both worlds, like a powerful villain who is stealing chakra and mutant powers. Maybe Naruto and Wolverine could bond over their shared experiences of having a power within them that they have to constantly control.
One great X - Men Rogue fanfic is 'Rogue's Redemption'. It delves deep into Rogue's character, exploring her struggles with her powers and her place among the X - Men. The story has a great plot that keeps you hooked from start to finish, with interesting character interactions, especially between Rogue and Gambit.
One possible plot could be that Naruto is somehow transported to the X - Men universe. He teams up with Wolverine. Naruto's unique ninja skills, like his shadow clones, could be used in combat against the Brotherhood of Mutants. Wolverine could teach Naruto about the concept of mutants and their struggles, and Naruto could in turn show Wolverine some of his ninja wisdom.
