If Naruto is trained by Cus in fanfiction, it would likely have a significant impact on his growth. Cus could introduce Naruto to new forms of training that focus on different aspects of his abilities. This might include more mental training rather than just physical. Naruto could also be exposed to different cultures or ways of thinking through Cus. For instance, Cus might have knowledge of ancient ninja arts that were lost in the Hidden Leaf Village. This training could open up new storylines, such as Naruto using these new skills to face stronger enemies or to resolve internal village conflicts in a more unique way.
Well, Naruto would probably gain some really unique magical abilities. Fairy Tail mages are known for their diverse magic, and Naruto could combine his chakra skills with something like Fire Magic or Celestial Magic. He might become even more powerful in combat, with new ways to attack and defend.
Naruto would gain better combat awareness. Kurama's experience in battles can be passed on to Naruto. He'll be able to read his opponents better, know when to attack and when to defend. This will make him a more formidable opponent in combat situations.

One possibility in this fanfiction could be that Naruto gains new and unique combat skills. Monkey D. Dragon is known for his revolutionary ideas and powerful abilities in the 'One Piece' world. Under his training, Naruto might learn different ways of strategizing and approaching battles, perhaps incorporating some of the more unorthodox fighting styles from the 'One Piece' universe. This could lead to Naruto becoming even more formidable, not just in terms of his ninjutsu, but also in his ability to lead and inspire others in a different way, much like how Dragon has an impact on the 'One Piece' world.
