The theme of growth is also prevalent. They both start as somewhat naive boys and grow into powerful and more mature individuals. In 'naruto is like killua fanfiction', you might see how they influence each other's growth, for example, Naruto's positive outlook might affect Killua's more cynical view at times, and vice versa.
Yes, there are some. You can start by looking on fanfiction websites. Some authors might create stories where they draw parallels between Naruto and Killua, perhaps in terms of their growth, their relationships with friends, or their unique abilities.
He could form a rival - like relationship with Sasuke. Both are highly skilled and have a bit of a dark side. They might constantly compete to prove who's better in combat.
In a Naruto world fanfic, Killua would bring a whole new dynamic. He has a dark past as an assassin which could either make him a feared or respected figure. His family's training has made him physically and mentally tough. In battles, he could use his electricity - based attacks in creative ways against ninjas. But he would have to learn about things like jutsus and the ninja villages. Also, his relationship with Gon in the HxH world was important for his character development, and in the Naruto world, he might find a similar bond with a fellow shinobi, which could change his perspective on things.
Yes, there are likely some fanfictions out there with such a concept. Fanfiction writers often come up with creative crossovers. You can try searching on popular fanfiction websites like Archive of Our Own or Fanfiction.net.
Maybe in the fanfiction, Naruto discovers Killua's world and is in awe of Killua's lightning - based abilities. He then tries to learn from Killua to enhance his own Rasengan or other jutsu. Also, it could involve the two of them teaming up against a common enemy that threatens both their worlds.
Gon in fanfiction can be very single - minded in his pursuit of goals, just like in the original. He might be a bit more naive at times, which can lead to interesting plot twists. Killua is often portrayed as having a complex emotional side. He struggles with his past as an assassin and his loyalty to Gon. His cool exterior may crack in some fanfictions, showing his true feelings.
Killua's character development in Naruto fanfiction could be quite extensive. He could start as a feared figure due to his assassin skills and strange powers. But as he spends time in the Naruto world, he'd be exposed to new values. He could develop morally, realizing that there are other ways to live than just following the path of an assassin. He could also develop his powers further by combining his nen with chakra - based techniques, and this journey of self - discovery and power - growth could shape him into a more well - rounded and positive character.
His abilities would likely cause quite a stir. Killua's ability to move at high speeds and his combat skills would make him a formidable opponent in the Naruto universe. Maybe he'd be seen as an outsider at first, but as he proves himself, he could be respected. His nen - based attacks could be misinterpreted as some strange new jutsu that the ninja haven't seen before. He might even team up with some of the more adventurous ninja like Naruto himself and go on wild adventures.
As I mentioned before, 'lemon' implies adult content which is not suitable for discussion. So, I can't really talk about the characteristics of such fanfics.
