Since I don't know the specific fanfic, it's hard to say for sure. But likely there would be the knight character, and perhaps Batman himself could be involved in some way, along with the character who marries the knight.
Perhaps the 'knight' is a new character created specifically for this fanfiction. This character could be a symbol of hope and justice, just like Batman, but with a more knightly code of conduct. Their marriage could be a way to introduce a new dynamic to the Batman universe.
A 'marry the knight batman fanfic' could potentially be about a female character (or male, depending on the interpretation) who falls in love with a knight - inspired character in the Batman franchise. The fanfic might detail how they meet, their courtship, and finally their marriage. It could also involve other elements from the Batman lore, such as dealing with villains who try to disrupt their relationship or the knight's own journey in becoming a hero in Gotham City.
The main characters include Batman, who is the protagonist and the Dark Knight protecting Gotham. The Arkham Knight, the new and mysterious adversary. Alfred, who has been with Batman through thick and thin, taking care of things at the Batcave and offering wisdom. Also, Commissioner Gordon, who represents the law in Gotham and is an important ally of Batman in the fight against crime.
The main characters are Batman, the Joker, and Harvey Dent. Batman is the Dark Knight, fighting for justice in Gotham. The Joker is the chaotic villain causing mayhem. Harvey Dent is the district attorney who gets caught up in the Joker's plans and later becomes Two - Face.
Obviously, Batman, or Bruce Wayne, is one of the main characters. He is at the center of the story as he is in most Batman - related works.
The main character is of course Batman. He's the central figure in the Dark Knight series. But we may also see Robin, who often partners with Batman. And Commissioner Gordon, who is Batman's ally in the police force. They play important roles in Batman's fight against crime in Gotham.
The main characters in 'Batman Gotham Knight Graphic Novel' include Batman, who is at the heart of the story, using his skills and gadgets to combat evil. Catwoman is another important character. Her ambiguous nature adds an interesting dynamic. Besides, there are villains like the Joker who are likely to make an appearance. His chaotic and unpredictable nature creates a great contrast to Batman's order and justice. And, again, Commissioner Gordon is there to uphold the law from the police side and collaborate with Batman when needed.
Batman is the main character, of course. He's the central figure around which the story revolves.
The main characters in the batman dark knight returns story include Batman, who is the protagonist coming out of retirement. Commissioner Gordon, his long - time friend and ally in the fight against crime in Gotham. Carrie Kelley, the young and feisty girl who becomes Robin. The mutant gang leader, who leads his gang in causing havoc and is a formidable foe for Batman. Additionally, there are characters in the media and in the political arena who play roles in either supporting or opposing Batman's return to vigilantism, all of which contribute to the rich tapestry of the story.
Batman is obviously one of the main characters. There are likely to be some of his well - known villains too, like the Joker. Other possible main characters could be Commissioner Gordon or Batman's other allies.
