Sasuke is often one of the characters. Given their complex relationship, Sasuke might see Naruto's banishment as another wrong done by the village and decide to support him in his revenge, especially if it means taking on the village's corrupt elements.
Perhaps Naruto returns to find his former world in chaos under the rule of a tyrant. Remembering the pain and suffering he endured there, he decides to take revenge by overthrowing the tyrant. He uses his ninja skills and his ability to inspire others to build a resistance.
During his revenge journey, Naruto might learn new skills not just in ninjutsu, but also in terms of strategy and manipulation. He could start using his wits more than his brute strength. This shows his growth from a simple - minded fighter to a more complex thinker. He might also start to understand the darker side of human nature, which makes him more cautious in his relationships.
It would create a huge shockwave. Naruto is a central figure, and his actions towards his family would change the dynamics of all his relationships. His friends would be deeply divided. Some might try to stop him, believing there must be a misunderstanding, while others might be swayed by Naruto's determination. The ninja villages would also be affected. Konoha, in particular, would face an internal crisis as Naruto is one of its most important assets. His revenge could lead to a split in the village, with some supporting Naruto and others standing by his family.
In the fanfiction, Naruto might think his family abandoned him on purpose. So, he starts to seek revenge. He could train hard to become extremely powerful. Along the way, he meets some people who try to convince him that revenge is not the answer. But his anger is so strong that he doesn't listen at first. Eventually, he might come across some evidence that shows his family had no choice but to leave him, which makes him question his revenge mission.
In a fanfic, Naruto could be driven to get revenge on his friends if there was a prophecy or some sort of fated event that made him believe they were going to be his downfall. Also, if his friends made a deal with an evil force to gain power at the expense of Naruto or his loved ones, he might feel the need to take revenge. Another factor could be extreme jealousy. If Naruto's friends suddenly got all the attention and recognition that he felt he deserved, and they flaunted it in a mean - spirited way, it could push him over the edge.
It's a very strange concept for a fanfic. Naruto is known for his strong bonds with his friends. In the Naruto universe, friendship is a major theme. So for him to get revenge on his friends would mean something really bad must have happened. It could be an interesting fanfic if the writer can come up with a really good backstory to justify it. For example, if his friends were somehow mind - controlled and did things that hurt Naruto deeply. But overall, it's not something we'd expect from the Naruto we know.
In some fanfiction, Naruto might seek revenge on his family if he finds out they have a dark secret that goes against his values. For instance, if he discovers that his family was involved in some unethical or cruel actions in the past. However, this would be a huge departure from the Naruto we know in the original series, as he is usually very forgiving. But in the realm of fanfiction, anything can be explored. Also, it could be a situation where Naruto believes his family has been hiding their true identities from him, and these identities are associated with something he despises.
It could be some hidden members of Naruto's family itself. Maybe there are relatives who have been manipulating things from the shadows and their actions led Naruto to believe he needs to take revenge on the family as a whole.
Well, Naruto could face old enemies who thought he was gone for good. They might be shocked when he returns seeking revenge. For example, if Orochimaru was still causing trouble, Naruto would use his newfound knowledge and strength to take him on.
