Well, in this fanfic, Naruto's use of the Speed Force could lead to some really interesting crossovers. Imagine him meeting characters from the DC Universe who are also associated with the Speed Force. He could learn new techniques from them or teach them some of his ninja skills. In terms of the Naruto world, his newfound speed could make him a more elusive target. He could use it to quickly gather intelligence across different villages without being detected, completely changing the power dynamics in the world of ninjas.
His power level would skyrocket. The Speed Force gives him the ability to move at incredible speeds, which adds a whole new dimension to his combat capabilities. He can now dodge attacks with ease and also deliver rapid - fire strikes.
The plot could involve Naruto being in a super - powerful form (godlike) and using the kyoketsu shoge in unique ways. Maybe he uses it to fight against powerful new enemies that are immune to his regular jutsu. He could also use it to protect his village in a more stealthy and unexpected manner compared to his usual flashy attacks.
Well, perhaps in this fanfic, Naruto's use of the chained knife could be part of a new fighting style he develops. Maybe he discovers the chained knife during a mission in a mysterious land. He then has to train hard to master it. As he is godlike, he quickly adapts and uses it to defeat powerful enemies in unique ways, like combining his chakra with the chained knife's movements.
Naruto might develop a 'Force - Shadow Clone Jutsu'. He could use the Force to create shadow clones that are more durable and have some Force - related abilities. For example, they could use the Force to sense enemies or even share knowledge between each other more effectively.
The Akatsuki could still be the main antagonists. Even with Naruto having the power of the Speed Force, they would pose a significant threat. Their various unique abilities and their goal of collecting the tailed beasts would still be in conflict with Naruto's desire to protect the villages.
One possible plot is that Naruto is tricked into using the dark side of the force. An enemy could deceive him, making him believe that it's the only way to save his village. As he uses it, he starts to change. His relationships with his friends become strained as they notice the dark influence on him. He then has to find a way to break free from the dark side's grip before it's too late.
Naruto might be able to merge with the Mokoton creations. For example, he could become one with a giant wooden dragon he created and control it from the inside, giving it his own chakra and intelligence for more strategic attacks.
One possible new jutsu could be the 'Force - Nature Manipulation'. Naruto loves nature and is already good at using nature - based chakra. With the force, he could go beyond just using chakra from nature. He could use the force to actually control natural elements like waterfalls, trees, and rocks directly. For example, he could make a whole forest move to his will, trapping his enemies or creating barriers. This would be a very unique and powerful jutsu that combines his ninja skills with the power of the force.
One antagonist could be a corrupted version of one of Naruto's old friends. Maybe they were influenced by some dark force and now have powers that rival Naruto's. They would oppose Naruto not only because of the power of the kyoketsu shoge but also due to their twisted view of the ninja world. Also, there could be a group of interdimensional invaders who see Naruto's power and the kyoketsu shoge as a threat to their plans of conquering the ninja world. They would use their advanced technology and unique abilities to try and defeat Naruto.
Perhaps Naruto, with his godlike powers, takes on the role of Taskmaster. He could use his ninja skills and superhuman abilities to set challenges for other characters in the Taskmaster's style.
