Most likely, Batman is the main character. He is the one who embodies the 'steel of hope' concept. But it could also feature villains. Maybe the Joker, as he is one of Batman's most iconic foes. Their interactions would be interesting in the context of a story about hope and steel - like determination. Additionally, Commissioner Gordon might play an important role as the link between Batman and the police force in Gotham.
The main character is surely Batman. His character is the core around which the 'steel of hope' theme revolves. However, depending on the plot, other characters might become prominent too. For example, if the story delves into Batman's past, his parents could be important characters, even if only in flashbacks. And if it's about a new threat in Gotham, new characters created specifically for this fanfic could also be main characters, but they would still be related to Batman's journey of being the symbol of 'steel of hope'.
It could be about Batman in a story where 'steel of hope' might refer to his unwavering determination. Maybe it shows how Batman uses his strength and hope to fight crime in Gotham, or it could be a story that focuses on a new aspect of his character related to hope while being as tough as steel.
It's probable that the main characters are the Avengers we know and love. However, in this fanfic, their characterizations might be different due to the'steel' aspect. Maybe Iron Man is more focused on developing steel - based weapons for the team. Thor's connection to steel could be explored, perhaps his lightning has an effect on steel in this universe. Hulk could have a new form that is related to steel in some way. And of course, there could be original characters who are central to the story, like a steel - forging dwarf (inspired by Thor's world) who helps the Avengers create new weapons and armors out of steel.
I don't know specifically as it's a fanfic. But it could be an original character created by the fanfic writer who has a passion for steel - type Pokemon. It might also include some well - known Pokemon characters like Brock who could offer advice on training steel - type Pokemon.
In addition to the well - known Avengers, there might be some new or less - known characters. Maybe some characters from Iron Man's rogues' gallery could show up. Or perhaps a new hero that is related to Iron Man's technology in some way. There could also be some side characters that are important for the development of the story, like Pepper Potts who has a close relationship with Iron Man.
Batman himself is obviously one of the main characters. Since it's about his identity being revealed, he would be at the center of the story dealing with all the consequences.
Batman is obviously one of the main characters. His presence is central as the story is likely based around his immortality. Robin could also be a main character, as he is often Batman's sidekick and their relationship would be different with Batman being immortal.
Obviously Naruto would be one of the main characters as it's in the title. There might also be his friends like Sasuke and Sakura. Maybe some new characters could be introduced as well who are in need of Naruto's hope - bringing influence.
I'm sorry, without reading the 'a pale hope rises fanfic' myself, I can't tell who the main characters are. It could be original characters created by the fanfic writer, or it could be characters from the original work on which the fanfic is based.
In some cases, characters that were minor in the original 'A New Hope' could be promoted to main characters in the fanfic. This gives the writer a chance to explore their potential more fully, such as Wedge Antilles getting a more prominent role in the story.
I don't know for sure since I haven't read this particular fanfic. But it could be the main characters from the Twilight series like Bella, Edward, and Jacob. Maybe the story focuses on them in a new situation where they are the ones who experience or bring about this glimmer of hope.
