Definitely Hinata. Since Hinata idolizes the Little Giant, a fanfiction with them together could be amazing. They could have training sessions where the Little Giant passes on his skills to Hinata. Another good character to pair with the Little Giant could be Kageyama. Their different playing styles could create an interesting dynamic in the story. And of course, Daichi. As the captain, he could learn a lot from the Little Giant's leadership on the court.
One common theme is inspiration. The Little Giant serves as a huge source of inspiration for the Karasuno players, and this is often explored in the fanfictions.
There are various types of interesting Haikyuu Little Giant fanfiction. For example, a story that details his first match and how he overcame his nervousness.

Another could be a fanfiction where the Little Giant has an unexpected encounter with an opposing team's star player outside of the court and they have a deep conversation about volleyball. Also, a story where the Little Giant mentors a young player who is having self - doubt could be really engaging.
Definitely Tony Stark. He has the brains and the resources. He and Little Bruce can collaborate on new inventions or ways to control the Hulk. Plus, their dynamic in the movies was really engaging. Natasha Romanoff is another excellent choice. She has a mysterious allure, and she can be a big sister - like figure to Little Bruce. She can protect him and at the same time encourage him to be more assertive. Thor could also be a good pairing. Thor's god - like strength and his own journey of self - control can be something that Little Bruce can learn from, and they can have some really fun adventures together.

Ezra could be an interesting character to pair with her. He's a teacher, so there could be a mentor - mentee type of relationship that develops into something more. His mysterious past could also add an element of intrigue to the story.
It's hard to say who the 'best' is as it depends on personal taste. However, some authors who are quite popular in the Giant Little Ones fanfiction community are those who really capture the essence of the characters. They write in a way that makes you feel like the characters are acting just as they would in the movie.
Aria could also be a good addition. Given her creative and artsy side, she might offer different insights compared to Spencer and Dean. She could also be involved in a love triangle situation, which would add more drama to the fanfiction. For example, if both Dean and Ezra were interested in Aria at the same time while she was friends with Spencer and Dean.
Uraraka could also be a great pairing. They could be really good friends, with Uraraka's positive and friendly nature bringing out the best in Izuku's little sister. They might study together, train together, and support each other through the challenges of being at the hero school. Uraraka could also introduce her to new friends and experiences.
