Red Hood is a character who has been variously depicted in comics. Sometimes it's Jason Todd, who was once Robin and came back with a more violent approach.
It could be someone manipulating Red Hood. For instance, a powerful crime lord who has some dirt on Red Hood and forces him to kidnap Nightwing. So, in a sense, this crime lord would be the real villain.
The main characters are Little Red Riding Hood, a young girl. And the wolf, which is the villain in the story. Also, there is Little Red Riding Hood's grandmother.
The grandmother can be a very interesting character. In some fanfictions, she's not just a helpless old lady. She could be a retired witch who still has some magic up her sleeve. For example, she might have enchanted the red hood to give Red Riding Hood special powers.
Catwoman can be a great character in such fanfiction. She has her own moral code that often clashes with Batman's. Her presence can create more tension and also add an element of romance. She could also interact with Red Hood in interesting ways, perhaps seeing some of herself in him.
There's an author named 'RedHoodLover99'. They have a series of fanfictions that are very popular. Their writing style is quite detailed and they do a great job of exploring the Red Hood's backstory and his relationships. Also, 'BatUniverseWriter' is known for writing some really good Red Hood fanfictions that are more action - oriented and keep you on the edge of your seat.
In 'Pulp Fiction', there isn't a character simply named 'the man in the red hood' in a straightforward sense. It could be that this is a misnomer or a very specific reference that doesn't directly align with a main character. Maybe it's a minor character that is easily overlooked or a description that has been misremembered.
Well, surely the Red Hood character is one of the main ones. There might also be the wolf, if it follows the traditional tale. And perhaps there are other characters like the grandmother, who could play an important role in the story.
His motivation could be related to a difference in ideology. Red Hood has a more brutal approach to crime - fighting compared to Nightwing. He might think that Nightwing's methods are too soft and by kidnapping him, he wants to force Nightwing to see things his way.
