His abilities might take on a more unpredictable edge. He could incorporate some of Joker's trickery into his combat. For example, using misdirection like Joker does in his schemes.
Naruto's ninjutsu could be influenced by the chaos around him. He might develop new jutsu that are more about causing confusion and disruption, similar to how Joker likes to disrupt the status quo. And with Harley's acrobatic skills, Naruto could also improve his own agility and flexibility in combat.
It would be a very chaotic story. Naruto's positive and determined nature would clash with Joker's insanity and Harley's wildness. Maybe Naruto would try to bring some sense of justice to their chaotic world.
His chakra control would likely be extraordinary. Kyuubi is a huge source of chakra, so Naruto would have had early exposure to vast amounts of it. This could lead to him being able to perform more advanced jutsu at a younger age.
Naruto's development would be a very interesting mix. In Kumo, he'd be exposed to different types of chakra natures and fighting styles. His Rasengan, for instance, could be modified with Kumo's lightning chakra to create a more powerful and unique attack. Minato's influence would ensure that Naruto has a solid foundation in space - time ninjutsu. Also, being in Kumo, Naruto might learn to control his Nine - Tails chakra in a different way, maybe with the help of Kumo's unique methods of chakra control. This would make him an even more formidable ninja compared to his original development in Konoha.
His physical abilities would be enhanced. Constantly running, climbing, and fighting in the forest would make him stronger and more agile. His stealth skills would be top - notch as he'd have to hide from the forest's predators.
His physical abilities would likely improve a great deal. Black Widow is a master of martial arts, so Naruto could become even more formidable in close - quarter combat. His agility and strength could be enhanced beyond what he achieved in the ninja world just through her training methods.
Naruto would likely develop his chakra control better. The toads could teach him unique ways to manage his chakra, like using it in harmony with the natural energy around him. This would make his Rasengan and other jutsu more powerful.
Naruto's character would experience a significant transformation. Firstly, he would become more diplomatic. Aphrodite's influence could make him more adept at resolving conflicts without always resorting to fighting. His view of the world would also expand. He would no longer just see things from a ninja's perspective but also consider the greater cosmic order that Aphrodite represents. This would lead to him making decisions that are more in line with the harmony of different realms, not just the ninja villages. He might also develop a more elegant fighting style, influenced by Aphrodite's grace, rather than his typical rough - and - tumble ninja style.
His magical abilities could develop in a very unorthodox way. In Wonderland, the laws of nature are so different. He might learn to use magic in ways that are more about manipulating the chaotic environment rather than the traditional spell - casting in the wizarding world. For instance, he could use magic to navigate through the constantly changing landscapes of Wonderland.
Naruto could have a greater control over his chakra. Since Kushina would be there to guide him, he would likely avoid some of the pitfalls he faced in the original story. His physical strength might also be enhanced as Kushina could train him in ways that utilize his Uzumaki bloodline more effectively.
Naruto's character would develop a different sense of loyalty. Instead of being loyal to Konoha, he'd be loyal to Kumo. His goals would change too. Maybe instead of aiming to be Hokage, he'd aim to be one of the top - ranking ninjas in Kumo. His social skills could also be different. Kumo has a different social environment, so he might be more rough around the edges in his interactions.
