One cool scenario is Naruto using magic to create illusions that are more powerful and realistic than normal ninja illusions. He could use it to deceive entire armies. Another is that he could use magic to heal wounds that are otherwise incurable with normal medical ninjutsu. And he might be able to teleport long distances in a flash of magic, which would be really useful during battles or for quick rescues.
Well, he might use his reality - controlling power to make himself the most powerful ninja instantly. He could also create a world where ninjutsu has no negative side - effects. For instance, no one would go blind from overusing the Mangekyo Sharingan. Or he could make it so that everyone can understand each other's language without any communication barriers in the ninja world.
A really interesting scenario could be that the other villagers start to notice some strange things going on at Sasuke's place. They suspect something is up but don't know exactly what. Naruto and Sasuke then have to be really careful to keep their living arrangement a secret while also dealing with the close - knit community's curiosity. This adds a layer of secrecy and tension to the story.
One cool scenario could be Naruto using Mokuton to create a huge wooden dragon that breathes out lava using his Lava Release. He could use this against a large group of enemies and wipe them out in one go. Another could be when he's in a tight spot, like surrounded by water. He uses Mokuton to create a floating platform of wood and then uses Lava Release to heat up the water around him, creating a steamy fog for cover.
One interesting scenario could be Naruto creating a whole new ninja village. He could use his creation powers to build the infrastructure, train the ninja, and establish a unique set of rules. Another scenario is that he creates a powerful weapon that changes the balance of power in the ninja world. Or he might create a magical creature that becomes his loyal companion and helps him in battles.
Imagine Harry being able to make plants sing. He could create a beautiful concert in the Hogwarts gardens with all the plants chiming in. Or he could use plants to create a floating garden in the sky above Hogwarts for a special event. Also, what if he uses his power to make plants that can detect lies? It would be a great help during interrogations or investigations.
In a training session, Naruto might 'own' Ino. Let's say they are training in teamwork with other ninja. Ino is having trouble keeping up with Naruto's high - energy and unpredictable fighting style. Naruto manages to adapt and work with everyone in the group, while Ino is left struggling. His ability to shine in the training and make the best of the situation can be seen as 'owning' in this context.
It changes his character development a great deal. First, it gives him an edge that he didn't have before. This could lead to overconfidence initially, but as he faces new challenges related to magic, he'll learn humility. Also, his dreams might expand. Instead of just aiming to be Hokage, he could now strive to master magic and use it for the good of the village in ways he hadn't thought of before. Maybe he'll start to see the world in a different light, not just as a ninja world, but one with magical elements as well.
