The anti Naruto ending fanfictions differ from the canon ending mainly in character arcs. In canon, Naruto becomes Hokage and brings peace. But in fanfictions, he might fail at this. Also, relationships are different. Canon has set pairings, but fanfictions can change that. For example, Sakura might end up with someone other than Sasuke.
The canon ending of Naruto is about hope, friendship, and the triumph of good over evil. Anti - Naruto ending fanfictions, on the other hand, often reject these ideals. In the canon, Naruto's ideology spreads and unites the ninja world. In fanfictions, his ideas might be seen as naive and lead to disaster. The world - building in fanfictions can be drastically different too. The unique abilities and cultures of the ninja villages that were somewhat preserved in the canon may be destroyed or distorted in anti - ending fanfictions.
In canon training scenarios, the training is often limited by the plot's pacing and the overall story arc of the Naruto series. But in serious training fanfictions, the training can be much more extreme. For example, in canon, Naruto's training with Jiraiya had a set structure and time limit. In fanfiction, that training could be extended indefinitely, with Naruto facing more and more difficult challenges. Also, fanfictions can introduce elements that are not part of the Naruto universe's canon. New types of ninjutsu or training tools can be added to make the training more unique.
Well, in canon, Kushina died when Naruto was born, so any interaction between them in fanfiction is non - existent in the original story. In fanfiction, we can see them interacting, like having conversations or going on missions together. Also, in canon, we only get a few flashbacks about Kushina, but in fanfiction, she can be a fully - fledged character with her own story arcs.
Well, in the original ending, Iron Man snaps his fingers to defeat Thanos and his army. But in the fanfiction, it could be someone else doing it. For example, Hulk could have found a different way to use the Infinity Stones that didn't require self - sacrifice.
In canon Naruto, Naruto is generally very loyal to Konoha. But in Dark Naruto Konoha Bashing Fanfiction, he's often at odds with the village. His attitude towards Konoha is much more negative. Also, in canon, Konoha is presented as a mostly good place with some flaws. In these fanfictions, Konoha can be shown as extremely corrupt and unjust.
The main difference is in the events and character arcs. 'Naruto canon divergence fanfiction' often changes major events. In the original story, the Fourth Great Ninja War had a certain sequence of battles and outcomes. But in fanfiction, it could be completely different, like different alliances forming during the war. Moreover, relationships between characters can be drastically altered. A minor character in the original might become a major love interest in fanfiction.
In canon, Shizune is a calm and collected character. But in a yandere fanfiction, her interactions with Naruto would be intense. Instead of just being a regular acquaintance as in canon, she would be overly obsessed. For example, she might glare at any girl who gets too close to Naruto, which is completely different from her normal behavior in the original story.
Regarding the differences in Naruto Konan bloodline fanfiction from canon abilities, her bloodline in fanfiction might have a stronger connection to her emotions. In the original series, it wasn't as clear. But in fan - created stories, her anger or determination could fuel her bloodline abilities to new heights. So, instead of just using paper for normal combat, when she's extremely angry, her paper could turn into a fiery substance, burning everything it touches. This emotional aspect adds a new dimension to her character and abilities that wasn't as prominent in the official Naruto story.
It differs in the sense that in canon, their relationship develops more gradually over time. In this fanfiction, since it's focused on the genin days, things might happen faster. For instance, the lemon part might introduce more intense emotional and physical interactions earlier than in the original story.
The official ending left many questions unanswered. Fanfics try to fill those gaps. For example, what happens to the Unsullied and Dothraki after Daenerys' death? In fanfics, they could be integrated into Westerosi society in more meaningful ways. Also, the power dynamics in the Seven Kingdoms are often reimagined in fanfics. Instead of Bran becoming king in a rather unexpected way, fanfics might have a more democratic system established, with different houses having more equal say in the governance of the realm.
The anime ending simplifies some aspects compared to the novel. In the novel, there are more detailed descriptions of the characters' internal struggles. For instance, Kirito's mental state is explored more thoroughly. In the anime, it's not as in - depth.
