One interesting plotline could be about the characters' journey to discover the true meaning of love in a post - apocalyptic world. Maybe they find that love can exist even without all the trappings of modern society.
One common plotline is Regulus joining the fight against Voldemort after faking his death. He uses his knowledge of the Death Eaters to help the Order of the Phoenix. Another is his relationship with Sirius. They get a chance to reconcile and work together.
One possible plotline could be Kushina teaching Naruto about the Uzumaki clan's secrets. Since she was an Uzumaki, she could pass on unique jutsu and knowledge that no one else in the village might know. For example, she could teach him advanced sealing techniques. Another plotline could be Kushina's influence on Naruto's relationship with the other villagers. Her presence might have changed how some of the villagers who were once cold to Naruto would now interact with him. Also, Kushina could be involved in the political affairs of the village, using her wisdom and strength to help Konoha face external threats more effectively.
One common plotline is the resurrection of dead characters. If Naruto is dead in the fanfiction, there could be a quest to bring him back. Another is alternate timelines where Naruto's life - or death - changes the course of the entire ninja world. For instance, if he dies early, the Akatsuki might achieve their goals more easily.
Often, in these fanfictions, Pyrrha comes back and has to deal with the aftermath of her 'death'. She might have to regain the trust of her friends who thought she was gone. There are also plotlines where she returns with new powers or abilities. For instance, she could have gained powers from the place she was 'preserved' in while she was 'dead'. Some stories also explore her relationship with Jaune again, now that she's alive, and how they pick up where they left off or start anew.
One possible plotline could be Spike and Fluttershy going on adventures together in the forest. They might discover new magical creatures and in the process, their bond deepens. Another could be them facing a misunderstanding in Ponyville that makes them realize how much they truly care for each other.
One possible plotline could be them teaming up against a common enemy and during the process, their feelings for each other start to grow deeper. They might have to save each other from dangerous situations, which strengthens their bond.
Perhaps a love potion is used to break an existing love triangle in the Naruto universe. For example, if Naruto, Sakura, and Sasuke were in a complex relationship, a love potion might be introduced to make Sakura see Naruto in a new light and resolve the tension. This could involve a lot of emotional drama and character development.
A really engaging plotline might be that Kenshi and Aura are from different social classes or species in the fanfiction world. Their love is initially frowned upon, but they fight against the prejudice. They might start a movement or journey to change the views of others, all while their relationship grows stronger. This would add elements of drama, adventure, and romance to the fanfiction.
One interesting plotline could be Naruto slowly realizing his feelings for Hinata during a dangerous mission. Maybe they get separated from the group, and in that time of solitude and relying on each other, Naruto starts to see Hinata in a new light.
Another plotline might involve Herobrine falling in love with an in - game non - player character. For example, a kind - hearted villager who doesn't fear Herobrine and through her kindness, she melts his 'evil' exterior and they fall in love. This could lead to Herobrine protecting the village from other threats.
