If Naruto reincarnates in RWBY fanfiction, his abilities would be a source of great interest. His teleportation jutsu, like the Flying Thunder God Technique, would seem like magic to the RWBY characters. His chakra control could also be something that they would try to understand and perhaps learn from. Since the RWBY world is full of different powers, Naruto's abilities would add another layer of complexity and excitement. They might see his abilities as a way to gain an edge in their fight against the Grimm and other threats in Remnant.
It depends on the oc's abilities. If the oc has abilities similar to those in the Naruto world, like some form of chakra - based power, they might be seen as a normal, albeit new, addition to the ninja community. But if their abilities are completely different, like having some kind of technological power, they could be feared or highly respected. For example, if the oc can create advanced weapons with their technology, some ninja might see them as a threat to the traditional ways of fighting.
His abilities would likely be seen as very strange and powerful. The apes have never seen anything like Naruto's jutsus. His ability to run up walls and create clones would seem like magic to them. Some might fear him, thinking he's a threat to their way of life. Others, especially the more curious apes, might be intrigued and want to learn from him.
His abilities would be seen as god - like. His speed and strength would be far superior to most shinobi of that time. For instance, his ability to create multiple clones would be a very strange and powerful sight for them.
His combat abilities would change a lot. Naruto's ninjutsu like the substitution jutsu could be used in new and interesting ways in Issei's world. His ability to sense chakra might be transformed into something that can detect the different types of energy in Issei's universe, such as the demonic energy or the holy energy.
His chakra abilities might be affected by the presence of Dust in RWBY's world. Maybe he could combine Dust with his jutsu. For example, using fire - type Dust to make his Fireball Jutsu even hotter. His physical abilities like speed and strength would still be an advantage, but he'd have to learn to use them in the context of fighting Grimm and other RWBY threats.
The girls of RWBY would have different takes. Ruby would see the potential for new adventures in the storylines. Weiss would be looking for well - crafted plots. Blake would notice the underlying emotions of the characters, and Yang would be all about the high - energy parts of the storylines.
His powers would likely be seen as very strange. The Naruto characters are used to chakra - based abilities, so Ichigo's spiritual powers would be a novelty.
His powers would be seen as extremely powerful and exotic. The ability to create multiple clones and use chakra - based attacks would be something completely new to the UA students and teachers.
Ruby's speed and scythe - fighting skills could be seen as a unique form of combat in the Naruto world. Her speed might be compared to that of some of the faster ninja like Rock Lee. Her scythe could be modified with chakra - based enhancements. Weiss's Glyphs could be related to some form of ninjutsu seals. She could use her Dust - infused attacks in combination with ninja techniques. Blake's shadow clones and her acrobatic combat style could be similar to some ninja's stealth and agility - based fighting. Yang's strength could be on par with some of the physically strong ninja like Tsunade, and her ability to absorb and release energy could be a new concept in the Naruto world.
Robot Naruto in RWBY fanfiction would probably have some amazing abilities. He could have super - strength, allowing him to lift heavy objects or overpower Grimm easily. His robotic body might also give him the ability to transform, like changing his arms into weapons or his legs into boosters for faster movement. Additionally, he could have some sort of energy projection, like shooting lasers from his eyes or hands.
