Harry might gain the ability to dodge attacks more easily. Sans has a certain 'instinct' for avoiding harm, and if Harry had this, it would be much harder for his enemies to land a hit on him. This would be really useful in duels, especially against powerful dark wizards. It could also make his Quidditch playing even more amazing as he could dodge bludgers effortlessly.
Well, if Harry Potter had sans powers, he might be able to teleport around Hogwarts easily. This would make it much simpler for him to avoid danger or get to his classes on time. For example, when facing Voldemort, he could suddenly disappear and reappear behind him to gain an advantage in battle.
One possible plotline could be Harry using his Sans powers to avoid danger in the wizarding world. For example, he might use teleportation abilities similar to Sans to quickly escape from Death Eaters. Another could be him using his powers in Hogwarts challenges, like getting through mazes or solving puzzles with his special skills.
Obviously, he'll interact with his main friends like Ron and Hermione. Ron might be both amazed and a bit jealous of Harry's new Sans powers at first. Hermione would probably be very curious and start researching to figure out where these powers came from. Harry might also interact with Dumbledore. Dumbledore would be intrigued and might offer some guidance on how to control and use these powers for good.
In the fanfiction, Harry Potter might gain the power of precise control. The Nuibari is known for its ability to stitch things together in the original Naruto context. So perhaps Harry could use it to 'stitch' spells together in a new and unique way, creating more powerful and complex incantations.
In this fanfiction, Harry could gain the power of enhanced perception. This would allow him to see things that normal humans or even wizards can't, such as the flow of spiritual energy. He might also gain the power to transform into a more powerful form, like a Shinigami's Bankai. His existing magical powers could potentially merge with his new Shinigami powers, creating something entirely unique. For instance, he could use his Patronus charm in a new way within the Shinigami world, perhaps as a form of spiritual protection.
He could have enhanced physical abilities like Black Widow. So, he'd be super agile, able to jump from high places and land safely, and have great reflexes. Also, he might be a master of disguise, which would be really useful in the wizarding world. He could blend in with different magical creatures or people to gather information.
He could gain the power to control time, which would be really useful in the wizarding world. He could go back and prevent some of the bad things that happened, like the death of his parents.
Naruto could gain enhanced senses from the Ghost Rider powers. In the Naruto world, this would help him in detecting hidden enemies or traps more easily. The ability to ride the flaming motorcycle would also be a new skill. This could be used for quick transportation during missions or battles. He could also gain the power of transformation into the Ghost Rider form, which not only gives him a more intimidating look but also access to all the other Ghost Rider abilities. And with the Ghost Rider's connection to the spirit world, Naruto might be able to communicate with spirits in the Naruto universe, which could lead to new plot developments.
In fanfiction, for Naruto to use Sans powers effectively, he first has to understand the nature of these powers. Sans' powers are quite different from Naruto's ninja abilities. Naruto should start by practicing the basic Sans powers like teleportation in a controlled environment. Once he gets a hang of it, he can incorporate it into his combat strategy. He can use Sans' power to create illusions similar to his shadow clone jutsu but with a different twist. For instance, instead of creating clones that can be easily detected, he can create illusions that are more like Sans' apparitions, which are harder to distinguish from the real Naruto. This would confuse his enemies and give him an upper hand in battles.
A common power in fanfiction is enhanced magical senses. Characters can sense magic from far away, like being able to detect a hidden magical artifact from miles away just by the faint magical aura it emits. This helps in treasure - hunting type of storylines.
