It could be Nightwing. He was once Robin himself and has a special connection to the current Robin. Nightwing might hear about the kidnapping and step in to save Robin, using his own unique fighting style and experience.
In many Batman and Robin fanfictions where Robin is injured, it often leads to Batman becoming more determined to catch the villain. For example, in some stories, Robin gets injured during a fight with a new, powerful enemy in Gotham. Batman then uses his detective skills to track down the bad guy while also taking care of Robin. He might call in Alfred for help with Robin's injuries. This kind of situation shows the deep bond between Batman and Robin and how they rely on each other in tough times.
The Penguin could be a great addition. His wacky and devious schemes always make for an interesting story. Also, Catwoman. Her complex relationship with Batman adds a layer of intrigue. And Oracle, who can provide valuable information and support from afar.
One interesting storyline could be Robin growing up and struggling to step out of Batman's shadow. He wants to prove himself as an independent hero while still respecting Batman's teachings.
There is no love story between them. Batman is more like a father figure or a strict mentor to Robin, guiding him in the fight against crime in Gotham City.
In the established Batman lore, a romantic relationship between Batman and Robin is not a part of the narrative. Batman's focus is on protecting Gotham City, and Robin is his sidekick. Their relationship is more about teamwork and the传承 of Batman's ideals. It's about passing on the skills and the sense of justice from Batman to Robin, not a love story.
In the original Batman and Robin concept, their focus is mainly on fighting crime and upholding justice in Gotham. However, in gay Batman and Robin fanfic, while they may still fight crime, the relationship between them becomes a central plot point. Their romantic or sexual connection might influence their decisions during battles, or how they approach other characters. For instance, they might be more cautious not to put each other in too much danger because of their love for each other. Also, the fanfic may explore different aspects of their personalities that are related to their relationship, like jealousy or possessiveness, which are not present in the original concept.
One main conflict could be their different approaches to justice. Robin might be more impulsive and want to take quicker action, while Batman is more methodical. Another could be Robin trying to prove himself as an equal rather than just a sidekick, which could lead to clashes. Maybe there are also differences in how they view the use of certain tactics or their relationships with other characters in the Young Justice universe.
One great 'Batman and Bane Fanfiction' is 'The Redemption of Bane'. It shows a different side of Bane, exploring his possible path towards redemption. The author does a great job of delving into the complex relationship between Batman and Bane.
