Well, obviously the Avengers like Iron Man, Captain America, Thor etc. would be main characters from the Avengers side. And from the Seven, whoever those characters are in that particular fictional context would be the main ones as well.
Sometimes, there could be other characters added in the fanfiction, like new villains that the Avengers and Jarvis have to face together. These villains can be original creations or lesser - known characters from the Marvel universe, which add new twists and turns to the story.
The main characters are the seven and Grover. We don't know exactly who the seven are in this context without more information from the fanfiction, but they are clearly important. And Grover, who is likely to have his own distinct personality and abilities.
The main characters would be the members of 'the seven' and the 'kanes'. But without more context about this specific fanfiction, it's hard to say exactly who each individual character is.
The main characters are the seven, which could be a group from a particular series. And of course, Percy and Annabeth. Percy is brave and has a great sense of humor, while Annabeth is smart and strategic. When the seven meet them, their individual traits will likely play a big role in how the story unfolds in this fanfiction.
I think 'avengers meet the seven fanfiction' might be a fan - created story where the Avengers and the Seven cross paths. It could explore things like cultural differences between the two groups if they are from different fictional settings. For example, the Avengers' values from the Marvel world and whatever values the Seven hold. It might also show how their different abilities work together or against each other in various scenarios like a big battle or a mission to save a world that is in danger due to some common enemy.
Obviously, Peter (presumably Peter Parker, Spider - Man) would be one of the main characters. And of course, the Avengers members like Iron Man, Captain America, Thor, Hulk, Black Widow, and Hawkeye are likely to be main characters too as they are the ones 'meeting' Peter.
Obviously, Rhodey and the Avengers members like Iron Man, Captain America, Thor, Hulk, etc. would be the main characters.
Obviously, the main characters would include the Seven. They are a group with their own unique identities and abilities. And then there's Magnus Chase. He is also a central figure in this fanfiction. Each member of the Seven, like Percy Jackson for example, brings their own story and skills to the mix. Magnus Chase has his own set of powers and a backstory related to Norse mythology. Together, they form the main cast of characters in this fanfiction.
In addition to the obvious ones, sometimes other characters like Happy Hogan or Pepper Potts might also make an appearance. Happy could be the one who arranges some of Peter's meetings with the Avengers. Pepper might be involved in providing resources for Peter's new tech or helping Iron Man manage his relationship with Peter. But the core always remains Peter Parker and the Avengers.
Well, obviously Tony Stark is one of the main characters. Then there are the other Avengers like Captain America, Thor, Hulk, Black Widow, and Hawkeye. Sometimes characters like Pepper Potts, who is important in Tony's life, also make an appearance. Rhodey, Tony's friend, might also be included as he often plays a significant role in stories related to Tony.
