Since I haven't read 'the black widow novel', I can only make assumptions. The main character is likely the Black Widow. She could be accompanied by a sidekick or a partner who helps her in her adventures or missions. There might also be a villain who is constantly opposing her, creating conflict in the story. And there could be some minor characters like informants or bystanders that add depth and context to the overall plot.
As I'm not familiar with this specific novel, it's hard to say for sure. However, if it's a typical story about a 'Black Widow' figure, there could be a male lead who is initially attracted to her but later discovers her dangerous side. There might also be a mentor - like figure who has some influence on the Black Widow's actions and decisions.
I don't know the exact main characters in 'the black widow novel' as I haven't read it. But it might have the Black Widow herself as a main character, and perhaps some other characters who are either her allies or enemies.
Black Widow is the central figure. However, there could be new characters created specifically for the prose novel. Maybe there's a mentor figure from her early days that we haven't seen much in other media. Or there could be a sidekick - like character that she teams up with during her adventures in the story.
If it's about a real - life inspired 'black widow' story, the main character would be the woman who is at the center of the events, like Belle Gunness who was suspected of being a black widow in the early 1900s. And there might also be the victims, her husbands or partners who play important roles in the story.
The main character is surely Black Widow. In addition, we may see characters like Nick Fury. Since he is a key figure in the Marvel universe and has often interacted with Black Widow in various operations. There could also be some new characters created specifically for this graphic novel to further develop Black Widow's story.
Natasha Romanoff, also known as Black Widow, is the main character. Other characters like Hawkeye might also play important roles as he has a connection with Natasha.
Black Widow is the main character without a doubt. Depending on the nature of the homecoming, there could be other characters involved. If it's about her going back to a place she grew up, there could be family - like figures, even if they are from the organization that trained her like surrogate parents or mentors from the Red Room. And if the story is set in a more recent context, there could be new characters who are helping or hindering her journey back to this place she considers home.
The main character in the Black Widow web series story is Natasha Romanoff, of course. She is the Black Widow. Yelena Belova is another significant character. She and Natasha have a complex relationship, perhaps as sisters in the context of the Red Room. There might also be characters from Natasha's past in the Red Room, like her trainers or other Black Widows, who could play important roles in the story.
Hawkeye and Black Widow are the central figures. Hawkeye with his sharpshooting skills and down - to - earth personality, and Black Widow with her spy - like skills and complex past. The baby is the focus of their attention and the story. And then there are characters like Iron Man who might be involved in providing resources or technological support to keep the baby safe. Thor could also be a part of the story, perhaps using his godly powers to shield the baby from threats.
Typically, the main character would be the so - called 'Black Widow' herself. She is the central figure as she is the one being chased. Then there would be the investigators or law enforcement officers involved in the case. They could be detectives, police officers, or forensic experts.
In addition to the Avengers, there could be original characters created by the fanfic writers. These characters could be doctors or nurses taking care of Black Widow in a secret medical facility. Or they could be other agents who have some connection to her past. Sometimes, even villains from the Marvel universe might interact with her while she's in a vulnerable state, either to gloat or to try and make a deal with her.
In a 'Black Widow Miraculous Ladybug' fanfic, aside from Ladybug and Black Widow, there could be villains as main characters too. Maybe Hawkmoth, the main antagonist in Miraculous Ladybug, could be a central figure. He would be interested in Black Widow's abilities and might try to either recruit her or find a way to take away her powers if she has any in the fanfic's universe. And Tikki, Ladybug's kwami, could also play a major role as she is the source of Ladybug's powers and could have some interesting interactions with Black Widow.
