Perhaps a fanfiction where Rumble gets injured while flying and Scootaloo helps him recover. During this time, they learn more about each other's dreams and fears. Scootaloo could share her insecurities about not being able to fly as well as other Pegasi, and Rumble could comfort her and tell her about his own struggles in flying competitions.
A really fun storyline could be a time - travel fanfiction. Rumble and Scootaloo accidentally travel back in time and have to find their way back to the present. Along the way, they meet younger versions of their friends and family, and they have to be careful not to change the future. This would be full of adventure and opportunities for them to grow closer as friends.
One interesting aspect could be the friendship development between Rumble and Scootaloo. In many fanfics, they might go on adventures together, which showcases their unique bond. For example, they could explore new parts of Equestria that are not often shown in the original series.
Friendship is a very common theme. They are often depicted as becoming good friends and helping each other out. For example, in many stories, they support each other during difficult times like when Scootaloo is having trouble with her flying lessons or when Rumble is feeling left out among his Pegasus peers.
Perhaps a story where Scootaloo and Rumble get into an argument over which pony tribe is better, the pegasi or the earth ponies. But then they are forced to work together when a strange magic starts affecting the ponies of their respective tribes. As they work together, they realize that each tribe has its own strengths and that they were wrong to argue in the first place.
Well, it could be about their adventures together. Maybe they team up to solve a mystery in Ponyville. They could be exploring an old, spooky place looking for a lost artifact or something.
One potential theme could be growth. Both characters could grow as individuals through their interactions. For instance, Scootaloo might become more confident and Rumble could become more empathetic.
Definitely Rainbow Dash. Since Scootaloo looks up to her, Rainbow Dash could offer some flying tips or be a mentor figure. Fluttershy would also be great. Her gentle nature could contrast with the more energetic Scootaloo and Rumble, and she could help them when they encounter some scared animals during their adventures.

One possible plot could be that a new character arrives in the Naruto world with the Rumble Rumble Fruit ability. This character could initially be seen as a threat by the Hidden Villages. However, as the story progresses, they team up with Naruto and his friends to fight a common enemy, like a powerful group of rogue ninjas. They use the unique powers of the Rumble Rumble Fruit, which can create and control lightning - like rumbles, to gain an edge in battles.
Well, one interesting thing could be the unique character development of Scootaloo in these fanfics. They might explore her in situations that the original show doesn't cover, like her facing some really tough challenges and coming out stronger, which makes her a 'badass' in the fanfic world.
Another could be a 'what if' scenario. Like what if a certain character got injured along the way and how it would change the dynamics of the group. This could involve exploring the relationships between the characters as they deal with the unexpected situation.
