One common element is that Naruto has extremely enhanced jutsu. For example, his Rasengan might be many times more powerful. Another is that he has unique kekkei genkai or abilities not seen in the original. He may also have superhuman speed and strength.
Well, it's somewhat popular. In the Naruto fanfic world, a lot of people are drawn to the idea of Naruto being op. It gives a sense of power fantasy and can lead to really interesting scenarios. For example, seeing how he'd handle enemies with his enhanced powers in unique ways compared to the original story. It also lets fans rewrite parts of the Naruto universe with a more dominant Naruto, which has its own charm.
Well, sometimes in an 'abandoned naruto op fanfic', the writing style can be quite distinct. The author might have been experimenting with a new way of narrating the story. It could have had a really fast - paced action - filled start that was leading to an exciting climax. Maybe it had some really vivid descriptions of the battle scenes that were different from what we usually see in other Naruto fanfics.
Another way is to check Naruto - related forums. There are often discussions about different fanfics in these forums. You can post a request asking if anyone knows of any 'abandoned naruto op fanfic'. People who are into Naruto fanfics might be able to point you in the right direction. They could share links or even give you some details about the ones they know.
In a lot of Naruhina fanfiction, Naruto is indeed OP. His character has so much potential for being OP given his origin in the Naruto series. He has the Nine - Tails within him, which is an incredibly powerful source of chakra. In fanfiction, authors can take this and run with it. They can make him so strong that he can change the whole ninja world on his own. When it comes to Naruhina fanfiction, his OP nature can also be used to show how he protects Hinata, making their relationship more endearing. For instance, he might be able to take on entire armies to save her, which is a common trope in such fan - made stories.
One plot idea could be Naruto and Hinata going on a mission together in a new, mysterious land. They face challenges that test their skills and also their relationship. Another could be a story set in an alternate universe where Naruto isn't the jinchuriki and he and Hinata have a more normal, but still exciting, relationship as they try to prove themselves in the ninja world.
One possible plot could be that Naruto, in his devil form, meets Serafall in the underworld. They start off as rivals, constantly competing in various devilish tasks or battles. But as time goes on, they begin to see the good in each other. Naruto's strong sense of justice and loyalty, which he carried from his shinobi days, intrigues Serafall. And Serafall's charm and power attract Naruto. Eventually, they fall in love and get married, uniting the power of the shinobi world and the devil world in a unique way.
In fanfiction, Naruto is often seen as OP (overpowered) because in the original series he already has a lot of powerful abilities like the Nine - Tails chakra, Shadow Clone Jutsu, and Rasengan. Fanfic writers might exaggerate these powers even more. For example, they could make his Nine - Tails chakra completely uncontrollable by his enemies, or give him new and insane versions of the Rasengan. Also, his growth potential in the original story is huge, and in fanfiction, this growth can be accelerated to make him extremely powerful very quickly.
In fanfics, Naruto might develop by becoming more patient. With Hinata, he has to understand her shyness and her different way of thinking. So he could grow in patience and empathy. Hinata, on the other hand, could develop by breaking free from her family's expectations in a more radical way. She could start to make decisions based on her own desires and her relationship with Naruto, rather than what the Hyuga clan wants. This would make her a more independent and strong character.
In Naruhina fanfiction, Naruto's OP nature can be attributed to multiple factors. His connection to the Nine - Tails is a big part of it. The Nine - Tails not only gives him a vast amount of chakra but also a certain level of invincibility. Additionally, Naruto's growth throughout the original Naruto series is often accelerated in fanfiction. He might master new jutsus faster or have a deeper understanding of his powers. His relationship with Hinata also plays a role. His desire to be a worthy partner for her and protect her can fuel his growth and make him seem even more overpowered. For example, he might train harder or unlock hidden powers because of his love for her.
