His powers could also be seen as monstrous if they start to take on new, grotesque forms. For example, instead of the normal blue - colored chakra, his chakra could turn into some sort of black, gooey substance that spreads and consumes everything it touches, like a monster devouring its prey.
Another way could be in the way his powers affect him. Maybe the use of his powers starts to corrupt him physically or mentally. His eyes could turn into some sort of inhuman or demonic - looking form, and his mind could be filled with uncontrollable rage and bloodlust every time he taps into his power, making him seem like a monster.
It might also be about how Naruto is treated or perceived in the fanfiction. If the other characters see him as a monster, either out of fear of his power or because of some misinformation or plot device, then that would create the feeling. This could lead to interesting storylines where Naruto has to deal with being ostracized or hunted because of this false perception of him being a monster.
In this kind of fanfiction, Naruto's power of persuasion could be influenced by Vulcan logic. Instead of just relying on his charisma, he could use Vulcan - style rational arguments to convince his opponents or allies. His shadow clone jutsu could also be improved. Maybe the clones could have a bit of Vulcan - like intelligence, allowing them to perform more complex tasks independently.
Melona might use her ability to split into multiple forms to surround an enemy while Naruto uses his shadow clone jutsu at the same time. This double - layer of clones and split forms would confuse the enemy and give them an advantage in battle. They could also combine their energy sources. Naruto's chakra and Melona's own unique energy could be merged to create a new, super - powered attack.
If Naruto had Arrancar powers, he might gain the ability to use Cero, which is a powerful energy blast. This could replace his Rasengan in some ways, or he could combine them for an even more devastating attack. His movement would also become more like an Arrancar's, perhaps with the ability to move at high speeds in a more fluid and menacing way. And his appearance might change, with some Arrancar - like features, which would shock his friends and foes alike.
Well, if Naruto had Wolverine's powers, his fighting style would be drastically different. He could use those adamantium claws in close combat, making him even more formidable in one - on - one battles. His healing factor would also be a game - changer. He could recover from injuries much faster, allowing him to keep fighting without having to rest as much. This might make him more reckless in battle, knowing he can heal quickly. Also, it could change his relationships with his friends and enemies. His enemies might be more afraid of him, and his friends might rely on him even more in dangerous situations.
Well, it would be a wild change. Naruto's original powers are based on chakra and his ninja techniques. With Raven's powers, he might not rely as much on chakra. His fighting strategy would be completely different. He could use Raven's power of creating portals to travel across long distances without using chakra - consuming jutsus. This would also allow him to surprise his enemies more often. And in terms of the overall plot, it could lead to new alliances and enemies. For instance, those who are after Raven's powers might now target Naruto.
Maybe it's some kind of special jutsu or a curse that backfires in a way that numbs his pain receptors. For example, a powerful sealing technique might have been placed on him accidentally or on purpose that has this side - effect.
Maybe it's some kind of ancient bloodline that was dormant in his family for generations. It suddenly became active in him.
In some Naruto fanfictions, Naruto's chaos powers might be shown as a wild and unpredictable energy source. It could make his jutsu more erratic but extremely powerful. For example, his Rasengan might become a chaotic, swirling mass of energy that can break through even the strongest defenses with ease.
Naruto's chakra - based powers and Maleficent's dark magic could either clash or combine. For example, Naruto could use his Rasengan, and Maleficent could add her dark magic to it, creating a super - powerful attack. Or their powers could be in opposition, like Naruto's life - affirming chakra against Maleficent's death - dealing magic.
