The main characters would also depend on the focus of the fanfiction. If it's more about a technological threat, then Iron Man and Miles (who also has some cool tech in his suit) might be the central focus. But if it's a more cosmic - level threat, then Thor and Miles could be the main characters dealing with it. There could also be villains as main characters in a sense, like if the story is told from the villain's perspective as they try to take advantage of the chaos when the two universes meet.
Well, in addition to the obvious ones, there could be some secondary characters that play important roles. For instance, Miles' friends or family from his universe might be involved. They could add a different perspective to the story. And on the Avengers side, characters like Black Widow or Hawkeye could have some interesting interactions with Miles. Black Widow could teach Miles some spy - like skills perhaps, while Hawkeye could show him some new archery techniques if Miles was interested. They all together would make the story more rich and engaging.
The plot might involve Miles being brought into the Avengers' world. He could introduce his unique powers and abilities to the Avengers. And they might initially be skeptical but then come to respect and rely on him. For example, his ability to turn invisible and his venom strike could be really useful in a fight against a villain like Thanos who is more used to dealing with the traditional Avengers' powers.
There could be other supporting characters too. Maybe some of Harry's friends from Hogwarts like Hermione and Ron could make an appearance in the fanfiction. They might be initially skeptical of Carskile but then grow to accept him. And on Carskile's side, he could have his own set of friends or family members who play a role in the story, for example, his sister who gives him advice on how to deal with Harry.
Obviously, Robin would be one of the main characters. And then, of course, the Avengers members like Iron Man, Captain America, Thor, etc. would be there as well.
Obviously, Draco Malfoy and Dudley Dursley are the main characters. Draco, with his blond hair and aristocratic air, is a well - known Slytherin from the Harry Potter series. Dudley, on the other hand, is Harry's cousin, a rather large and spoiled Muggle boy. Their encounter would be the central focus of this fanfiction.
Obviously, Obito is one of the main characters. He has a complex backstory and his presence is bound to have a big impact on the Akatsuki.
Obviously, Percy and Poseidon are the main characters. Percy, the young demigod with his courage and powers, and Poseidon, the powerful god of the sea.
The main characters would be Hermione, Bellatrix Lestrange, and maybe Rodolphus Lestrange. Hermione is the hero of the story, and Bellatrix is a very well - known and crazy Death Eater. Rodolphus could be there to add more of the dark family's presence and power dynamics.
Obviously, Naruto would be one of the main characters. He's the central figure from the Naruto universe. And then there would be the Pokegirl. She could be any type of Pokegirl, like a Pikachu - girl or a Charmander - girl. Their different personalities and abilities would drive the story forward.
Obviously, Naruto and Jiraiya would be the main characters. Naruto, the protagonist of the original series, and Jiraiya, his mentor. They have a deep connection, and any fanfiction about them meeting would revolve around their relationship.
Obviously, Ginny Weasley is one of the main characters. She's a strong - willed and brave witch. The Marauders, which include James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew, are also likely to be main characters. They are known for their mischief - making and loyalty to each other. Dumbledore might also make an appearance as he was around during the Marauders' time and would surely have some role to play if Ginny is interacting with that era.
