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.
Robin would probably be very hurt. He might initially go into a state of shock and disbelief. After that, he could try to find evidence to prove his innocence. For instance, he might search for surveillance footage or eyewitnesses.
I can't provide Nicole Robin's novel because Nicole Robin is a fictional character and there is no specific plot related to her. She appeared in many novels such as One Piece, Death, and other comics and novel chapters, but each work had its own storyline and character setting. If you are interested in a particular plot or character, I can do my best to provide you with relevant information.
In a fanfiction, Robin could be injured in a trap set by an old enemy of Batman. This enemy specifically targeted Robin to get back at Batman. Batman, upon finding Robin injured, is consumed with guilt and anger. He goes on a full - scale investigation to find the enemy. Meanwhile, Robin is in a critical condition and Alfred has to use all his medical knowledge to keep Robin alive. The story could focus on Batman's internal struggle between his need for revenge and his responsibility to Robin, and how he overcomes this to save both Robin and Gotham.
It's not a definite yes or no. Comics often present complex character arcs, and Robin's sexuality is not always clearly depicted as gay. It depends on the specific comic series and the author's intent.
Definitely fiction. Robin Hood's adventures are part of folklore and imagination. There's no historical evidence to prove his existence as depicted in the stories.
