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.
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.
The color red in her hood can symbolize passion or a vivid presence. It makes her stand out in the dull and dark forest, perhaps representing her being different or special in a rather dangerous world. It could also be a sign of her life force, which the wolf is ultimately trying to destroy.
The story starts with Jason Todd as Robin. His death was a dark moment for Batman. But his return as Red Hood changed everything. Red Hood has his own brand of justice. He doesn't shy away from killing criminals. Batman, being the Dark Knight with his strict moral code, can't abide by this. Their interactions are full of tension. Red Hood challenges Batman's ideology, and Batman tries to rein in Red Hood. It's a story of two different approaches to fighting crime in Gotham, with a lot of personal history and emotion thrown in.
One idea could be that Red Hood and Supergirl team up to stop a powerful alien threat that has infiltrated Gotham City. Red Hood's street - smart skills combined with Supergirl's superpowers would make for an interesting dynamic.
The story arc where Red Hood teams up with Batman again after their initial conflict is also a great one. It shows how they can put aside their differences to fight a greater evil. Their interactions, the way they work together despite their past issues, is really fascinating and a must - read for any Red Hood fan.
The 'red hood novel' could be about many things. It might be a retelling of the classic Red Riding Hood story, perhaps with new twists on the characters and plot. Maybe it focuses on the Red Hood as a more complex character, exploring her motives, her past, and her relationships in a fictional world.
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.
