A great plot could be a post - war scenario. The village is in the process of rebuilding, and Naruto and Hinata are both heavily involved. They work side by side to help the villagers. Hinata is always there to support Naruto when he feels the pressure of being the hero. Naruto starts to see Hinata in a new light, not just as a friend but as someone he could love. Their love story could be intertwined with the restoration of the village.
First, focus on their characters. Naruto is energetic and has a big heart, while Hinata is shy but strong - willed. Highlight these traits in your writing. For example, when Naruto makes a bold move in the story, show how Hinata admires his courage. Second, create interesting situations for them to interact. It could be a life - threatening battle where they protect each other. Also, don't rush their relationship. Let it develop gradually, like Hinata slowly becoming more confident around Naruto as their friendship deepens.
One plot idea could be Tobirama's early days as a ninja. Explore his training, his relationship with his brother Hashirama, and how he developed his unique jutsu. Another could be a time - travel story where a modern - day Naruto character gets sent back in time and has to interact with Tobirama. Or perhaps a story where Tobirama has to deal with a powerful new enemy that challenges his beliefs and leadership.
There could be a plot where Charlie and Bumblebee go on a road trip across the country to find a missing Autobot artifact. Along the way, they meet new friends and foes. They also have to deal with the challenges of being on the road, like running out of gas (for Charlie's vehicle part of the journey) and avoiding bad weather. At the same time, they are being hunted by a group of Decepticons who also want the artifact.
A good plot could be that Catwoman steals a valuable item that has some connection to Dick Grayson's past. Dick, as Nightwing, tracks her down. Instead of fighting, they start to talk and realize that there are bigger forces at play trying to frame Catwoman for a crime she didn't commit. They then join forces to clear her name and expose the real villains. Or, there could be a story where Catwoman and Dick Grayson meet at a masquerade ball in Gotham. They don't know each other's identities at first and end up sharing a dance and a deep conversation. Later, when they discover who they really are, they have to deal with the fact that they are on different sides of the law but still have feelings for each other. Also, a plot could be about Catwoman teaching Dick Grayson some of her stealth skills, and in return, Dick teaches her some acrobatic moves. This leads to a closer relationship between them and they end up using their combined skills to stop a major crime in Gotham.
A great plot could involve Arcee getting injured during a fight and Optimus Prime having to protect her while she recovers. During this time, they could have deep conversations about their hopes for the future of their race. Or perhaps there's a fanfic where they discover an ancient artifact that has a connection to both of their pasts, and they have to work together to unlock its secrets.
One idea could be exploring the backstories of minor characters during the Great War. Maybe show how they got involved and what their personal stakes were.
One idea could be a role - reversal plot. Instead of the usual power struggles between Kaguya and Miyuki, have them switch personalities for a day. It would be hilarious to see Kaguya being overly confident and forward, while Miyuki is shy and hesitant.
One idea could be that the two fated lovers are from different worlds, like one is a human and the other is a supernatural being. They meet by chance in a strange situation and start to feel an unexplainable pull towards each other.
One idea could be exploring the backstories of the characters in more depth. Maybe a character has a past trauma related to love that makes them act the way they do in the original story. Another could be a 'what if' scenario, like what if two characters who were enemies in the original fell in love in the fanfic.
One idea could be Basil solving a mystery in a new, strange part of the mouse city, like an abandoned underground area filled with old secrets. Another could be Basil teaming up with a new, young mouse detective in training to solve a case that's baffling the entire mouse detective community. Or perhaps a story where Basil has to solve a mystery on a ship sailing to a far - off mouse - inhabited island.
