Mighty and domineering were synonymous with dignity, heroism, solemnity, solemnity, weight, might, bravery, divine might, prestige, might, forthright, mighty, and so on.
One popular theme is friendship. The Mighty Nein is all about the strong bonds between the characters, and fanfictions often explore how those friendships grow and endure through different challenges.
Another type of Mighty No 9 fanfiction might be a 'what - if' scenario. For instance, what if the roles were reversed and the villains were the ones trying to protect the world from a greater threat while the heroes were causing chaos. This would lead to a really interesting and unique take on the existing story.
Naruto could use his Uzumaki bloodline's chakra reserves. He might overwhelm Might Guy with a large number of shadow clones, confusing him and creating an opening to save Tenten.
I'm not entirely certain, but perhaps 'tiny and mighty' could describe the characteristics of the characters. And 'five and two' might be related to the number of certain elements in the story, like five good guys and two bad guys or vice versa.
Some popular ones might include those that focus on the team's journey to a new championship. They could involve new characters joining the team and how they adapt to the Ducks' unique style of play.
