One impossible ability could be the power to time - travel freely within the Naruto universe. This would disrupt the whole timeline and sequence of events in the original story. Another might be the ability to instantly resurrect any fallen character without any cost or consequence, which goes against the finality of death in the Naruto world. And perhaps the power to control all the natural elements simultaneously with no training, while in the original Naruto, mastering multiple elements is a great and difficult feat.
In Naruto fanfiction, we might see an impossible ability like the protagonist having the power to nullify any attack just by thinking about it. This is completely against the combat mechanics of the Naruto series where every attack has to be countered with proper jutsu or physical skills. Another example could be the ability to transform into any mythical creature not related to the Naruto universe, like a European dragon. And there could be the ability to bestow ninja skills on non - ninja characters, making them instantly powerful, which doesn't align with how the Naruto world functions in terms of training and natural talent.
In some fanfictions, Naruto might have the power to control time. For example, he could freeze time during battles to gain an advantage. Another impossible power could be the ability to instantly teleport to any location in the ninja world without using any known jutsu. He might also have the power to communicate with all living beings telepathically, which is not part of his original abilities in the official story.
Impossible abilities can greatly disrupt the plot. For instance, if a character has the ability to teleport anywhere instantly, it can eliminate the need for travel and many of the encounters that were originally part of the story. It can also make battles less interesting as they can easily avoid attacks or reach opponents without any real effort. This changes the whole dynamic of the story.
Well, for example, Sasuke's sharingan can be used in a Mission Impossible - like scenario. He could use it to quickly analyze the security systems of a heavily guarded place that Naruto needs to infiltrate. Just like how in Mission Impossible they analyze the layout and security details before a mission.
One example is the story of Romeo and Juliet. Their families were feuding, which made their love seemingly impossible. Another could be the love between a human and a mermaid in some fictional tales. The differences in their natures and the worlds they belong to create an impossible situation for their love to thrive.
One example could be a student from a poor family who couldn't afford proper study resources. But through hard work and using free online courses, they managed to ace their exams and got into a top graduate school. They spent countless hours in the library using borrowed books and public computers.
One idea could be that Naruto is sent on a mission to infiltrate a hidden village that is suspected of creating a new and dangerous jutsu, much like the Impossible Missions in the movies. He has to disguise himself as a common traveler and gather intel without being detected by the village's powerful ninjas.
One key element is the combination of skills. Naruto's ninja abilities like shadow clones and his superhuman strength should be paired with Mission Impossible - style gadgets and stealth techniques. Another is the setting. You could have the story take place in both the Naruto universe and some high - tech locations similar to those in Mission Impossible. For example, a high - security building in a modern - day city.
One example is the movie 'Avatar'. The main character, a human, falls in love with an alien - like being from Pandora. Their love is impossible in the sense that they are from different species with different anatomies and cultures, yet they manage to form a deep emotional bond.
In some fanfictions, Naruto could have the predator ability of stealth. He might be able to move silently and blend into the shadows, similar to a ninja - like predator. This would make him a formidable opponent as he could surprise his enemies and strike when they least expect it. It also adds an element of mystery to his character.
In some fanfictions, Harry might have the ability to communicate with magical creatures on a deeper level than in the original books. For example, he could understand the thoughts and feelings of dragons, which gives him an edge in dealing with them.
