Perhaps he has hidden the full extent of his Sage Mode abilities. He might be able to stay in Sage Mode for a much longer time than he has shown so far, or have some other undisclosed powers within that mode, like the ability to sense enemies from much greater distances.
Maybe he wants to surprise his opponents in battles. He could be waiting for the perfect moment to reveal his full power and turn the tables on his enemies.
One cool Naruto skill in fanfiction could be the ability to combine multiple elemental jutsus effortlessly. For example, mixing fire and wind to create a super - powerful and unique attack. It adds a new level of badassery to his character.
Another possibility is that Naruto has a plan that requires him to keep his skills hidden from everyone, including Hinata, for a while. He could be waiting for the right moment to reveal them and use them to surprise and save the day, especially when it comes to protecting Hinata from a big threat that he anticipates.
Well, in certain Naruto fanfictions, there are hidden skills such as the 'Soul Link'. This allows two ninjas to share their chakra, skills, and even thoughts for a short period. It can be a powerful tool in battles where teamwork is crucial. Then there's the 'Void Step' which is like a super - advanced form of the body flicker technique. It enables the user to seemingly disappear into a void and reappear at a different location without being detected. And one more could be the 'Aura Manipulation' where a ninja can create an aura around themselves that can either boost their physical abilities or have an effect on the emotions of those around them.
Naruto was a very famous Japanese manga and anime. There were many characters with various skills. The following are the skills and characters of all the characters in Naruto:
1. Naruto Uzumaki: Naruto Uzumaki is a ninja. He has powerful skills such as Shadow Clone Technique, Spiral Ball, Tail Beast Jade, and so on. Among them, Shadow Clone Technique was one of his most famous skills. He could create many replicas to carry out missions.
2. Uchiha Daito: Uchiha Daito is a ninja. He has powerful skills such as the Reincarnation Eye and Susanofu. Among them, the Reincarnation Eye was one of his most famous skills. He could control time and space to teleport and travel.
3 Nagato: Nagato is a ninja who possesses one of the strongest ninjutsu techniques of the Kiba Village-Shadow Clone Technique. In addition, he also had an ability called the "God Domain" that could turn his body into a powerful energy body that could resist most attacks.
4. Okami: Okami is a ninja. She has powerful skills such as healing abilities and the strength of a thousand hand pillars. The healing ability could cure almost any disease, and the power of the Thousand Hand Pillar could give her unlimited stamina and strength.
5. Selaiya: Selaiya is a ninja. He has powerful skills such as prophecy and immortal mode. Among them, the prophecy ability could predict the future, while the immortal mode could improve the ninja's physical fitness and strength.
6 Orochimaru: Orochimaru is a ninja. He has forbidden skills such as Orochimaru Space and Orochimaru Fist. Among them, the Orochimaru Space allowed him to teleport anywhere in an instant, while the Orochimaru Fist allowed him to unleash powerful fist wind attacks.
7 Scorpion: Scorpion is a ninja. He has powerful skills such as illusion and poison. Illusion allowed him to create fake enemies to carry out missions, while poison allowed him to use various poisons to attack the enemy.
8 Dedale: Dedale is a Ninja. He has powerful skills such as Explosion and Pyrowork. Explosion allowed him to create all kinds of powerful explosions to attack the enemy, while Pyrowork allowed him to create all kinds of beautiful fireworks to confuse the enemy.
Naruto's Rasengan would be a key skill. He might start with a basic Rasengan and as the fight progresses, he could develop it into a more powerful form like the Big Ball Rasengan. His shadow clone jutsu would also play a major role. He could create a large number of clones to surround Tsunade, confusing her and making it difficult for her to target the real Naruto.
Perhaps Naruto, being a mechanic in this fanfiction, uses his shadow clone technique in a unique way. He could create clones to work on different parts of a large mechanical project simultaneously. Each clone could have a specific task, like one clone handling the wiring while another works on the engine assembly, similar to how he uses clones in combat to surround and outnumber his opponents.
Maybe Naruto could use math to calculate the trajectory of his shurikens more accurately, like using angles and velocities in math to ensure his attacks hit the target precisely.
In fanfiction, if Naruto joined Team 8, his skills would be quite an interesting addition. His chakra control, which he has improved over time, could be useful in situations where Team 8 needs precise maneuvers. For example, when Shino is using his bugs to infiltrate an enemy location, Naruto could use his chakra control to assist. His Nine - Tails chakra, although dangerous, could also be a powerful weapon in the team's arsenal during really tough battles. His skill set would blend well with Team 8's existing skills like Hinata's Byakugan - based tracking and Kiba's sense of smell - based tracking, creating a more versatile team.
