Well, maybe in this fanfiction Naruto has some clashing values with Makarov. Naruto values loyalty and friendship highly, if Makarov somehow goes against these concepts in the fanfic, Naruto could hate him.
Yes, there are some out there. You can start by looking on popular fanfiction websites like FanFiction.net or Archive of Our Own. Some fanfictions might explore unique storylines where Naruto is related to Makarov in this fictional scenario, like Naruto having some of Makarov's magic abilities transferred to him in a cross - over world. However, the quality can vary greatly, so you might need to read a few to find the really good ones.
No, Naruto and Makarov come from two completely different anime series, Naruto and Fairy Tail respectively. In the original stories, they have no relation at all. But in fanfiction, the rules are different. Some fanfic writers might come up with the idea of Naruto being Makarov's father just to mix up the elements from the two series in a very strange and unexpected way. This could be for the fun of it or to explore new storylines that are not bound by the original settings.
One possible plot could be that Naruto discovers his relation to Makarov later in his life. He then travels to the Fairy Tail world to learn more about his heritage. Along the way, he might face challenges from both Naruto's world enemies who follow him and Fairy Tail enemies who don't trust this new stranger. He has to use his ninja skills and the newfound magic abilities he might inherit from Makarov to prove himself and protect his new family.
Well, one possible plot could be that Naruto is initially unaware of his relation to Makarov. He lives his life as a ninja in Konoha. But then, some strange events start to happen that lead him to discover his Fairy Tail heritage. Maybe there are some magical items from Fairy Tail that end up in the Naruto world. As he delves deeper into his new - found connection, he travels to the Fairy Tail world. There, he has to learn about magic and also deal with the politics of the Fairy Tail guild, all while trying to figure out how he fits in as Makarov's grandson.
In such a fanfiction, there could be a whole new backstory. For example, Naruto might have been on a mission that took him to a different dimension where he met Makarov's mother. The story could then explore how Naruto's values, like his strong sense of friendship and never - give - up attitude, are passed down to Makarov. There could also be a conflict as Naruto tries to balance his life in the Naruto world and his new role as a father in the Fairy Tail world. It could be a story full of action, emotion and unexpected twists.
One possible reason in fanfiction for Naruto hating Minato could be the lack of a normal family life. Naruto was alone most of his life, not knowing his father. If he were to find out about Minato's actions in a negative light, like seeing the sealing as a selfish act to save the village at his expense, he could develop hatred. Fanfictions often take these complex emotions and build stories around them.
Maybe he hates it because it often distorts the real ninja world he knows. Fanfictions might create false or out - of - character scenarios that he can't stand.
Yes, there probably is. In the Naruto fandom, there are various fanfiction themes, and the 'narusaku' (Naruto - Sakura relationship) with Naruto hating Sakura can be an exploration of an alternative take on their relationship. Some fans might write this to explore what - if scenarios or to express their own views on the characters' dynamics that deviate from the canon.
