Maybe the Rider is summoned by Child Emyia to help in a battle tournament. As they compete, they learn more about each other's strengths and weaknesses and form a strong bond. Along the way, they face opponents with various powers and abilities.
A more complex plotline could be that Child Emyia accidentally summons the Rider while trying to perform a different spell. The Rider, being from a different realm, has a completely different set of values and goals. At first, they clash, but as the story progresses, they come to understand each other and work towards a common goal that is beneficial for both their worlds.
One great fanfic in this regard could be 'The Summoning of Rider by Child Emyia' on FanFiction.net. It has an interesting plot where Child Emyia's summoning of the Rider leads to unexpected adventures. The character interactions are well - written, especially how Child Emyia tries to understand and work with the Rider's powers.
A possible plotline could be that the Ghost Rider's power somehow leaks into the Vampire Knight world. For example, a strange portal opens and the essence of the Ghost Rider enters Cross Academy. This causes chaos as the vampires and vampire hunters are affected in different ways. Some vampires might be weakened by the holy fire aspect of the Ghost Rider, while some hunters might gain new powers. The characters then have to figure out how to close the portal and restore balance.
A possible plotline is that the scarab is actually a guardian of a secret ninja art. Naruto has to prove himself worthy to the scarab in order to learn this art. Along the way, he faces many challenges and battles, but with the help of his friends, he manages to earn the scarab's trust and gain the new power.

One possible plotline could be Hermione discovers a hidden dragon lair and forms a bond with a young dragon.

Well, one possible plot could be that the servant Naruto summons is from a future time. This servant has knowledge of events that are yet to happen in the Naruto world. Naruto then has to use this knowledge wisely while also keeping the servant's origin a secret from others who might misuse it.
In such a fanfic, a possible plotline could be Skye initially keeping the pregnancy a secret from most people out of fear or uncertainty. As the pregnancy progresses, she might start to show signs that are hard to hide, leading to a discovery by some of her friends. This could cause a rift in the group, with some believing she made a mistake and others trying to be supportive. Meanwhile, Ward could be trying to prove himself worthy of being a father, perhaps by taking on dangerous missions to secure a future for his unborn child and Skye. The story could also explore how their relationship evolves during this time, whether they grow closer or face more difficulties.
One possible plotline could be Loki's journey of self - discovery. After being abandoned as a child, he might struggle with feelings of unworthiness.

In some plotlines, the hurt child could be in a hospital where BTS is visiting for a charity event. They notice the child is withdrawn and sad.

One possible plotline could be that it's all a big misunderstanding. Maybe there's a false pregnancy test result due to some strange jutsu or mix - up. And throughout the fanfic, Naruto and Temari are trying to figure out what's really going on while also dealing with the reactions of their friends and families. Another could be that they are in an alternate universe where they are part of a magical ritual that binds them in a way that makes it seem like Temari is pregnant with Naruto's child, but it's really about a deeper connection they need to understand.
