One common plot point could be Naruto's sudden change in ideology. He might shift from being a protector to a destroyer due to some extreme event. Another is the reaction of his friends and former allies. They would be shocked and try to stop him, which could lead to some intense battles. And often, there would be a mysterious force or character behind his transformation.
Often, in these fanfictions, there is a build - up to Naruto's breakdown. It could start with small acts of aggression that gradually escalate. His relationship with Sasuke might also play a crucial role. Maybe Sasuke tries to reason with him, but Naruto is too far gone. And the world governments or ninja councils would be in chaos as they try to deal with the threat of Naruto.
Maybe Naruto gets some sort of dark power that makes him go berserk and start destroying everything in his path. For example, he could be influenced by an ancient evil curse.
One possibility could be that Naruto is somehow transported to the world of Greek mythology where Olympus exists. Maybe his powerful jutsu are seen as a threat to the gods on Olympus. He could start by accidentally causing chaos in a nearby village which gets the attention of the minor gods. As they try to stop him, he realizes he has to fight back to protect himself and in the process, his attacks end up targeting Olympus.
Another plot point is that Naruto's determination and never - give - up attitude play a big role. In these fanfictions, he might face many obstacles while trying to save Yugito, like multiple strong enemies or difficult terrains. But he always perseveres. He might have to fight against some powerful Akatsuki members who have captured Yugito. His ability to quickly analyze the situation and come up with a strategy is also often highlighted in these stories. For example, he could use his knowledge of the Sharingan (if he has some understanding of it from his battles with Sasuke) to predict his enemies' moves and save Yugito at the right moment.
A lot of these fanfictions have a theme of isolation. Naruto is pushed away from Team 7, either physically or emotionally. For example, they might exclude him from important missions or conversations, which makes him resent them. Another plot point could be a shift in Naruto's character. Due to the hatred, he might become more cynical or bitter, and this change in his personality is often explored in these fanfictions.
A common plot point is Naruto's sudden appearance in Erza's world or vice versa. Maybe there's a magic - chakra mix - up that causes this. Then, there's the actual rescue part where Naruto uses his signature moves like the Summoning Jutsu to get help in saving Erza.
One common plot point is Naruto having unique powers from being Moka's son. Another is how the Naruto world reacts to his new identity.
One common plot point is the initial transformation. It could be due to a jutsu gone wrong or a curse. Another is how Naruto adapts to his new cat body, like learning to walk on four legs and use his new senses.
In this kind of fanfiction, Naruto might be banished due to some false accusations or political conspiracies in Konoha. Once banished, he could decide to destroy Konoha out of anger and a sense of betrayal. He may have learned powerful jutsus during his exile and use them against the village that once rejected him.
The tides would be severely affected. Since the moon has a gravitational pull on the planet, without it, the oceans would become very unstable. Coastal areas would experience massive floods and then receding tides like never before, which would disrupt fishing and coastal communities.
One common plot point is Naruto's search for his identity. Since he's neglected by his parents, he has to figure out who he is on his own. And with the Mokuton aspect, it often involves uncovering a hidden family connection related to Mokuton. Another is his struggle to gain power. He's determined to become strong using Mokuton to prove that he can succeed without his parents' support.
