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.
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.
Nightwing could also be a likely savior. He was once Robin himself and has a strong bond with the current Robin. He might take it upon himself to rescue Robin, using his own unique fighting style and experience to outwit the Joker. Plus, he has his own network of contacts in Gotham that could help in the search.
Artemis is also a frequent ally. She and Robin can form a great team, especially if Robin's powers are of a certain nature. For instance, if he has enhanced agility, he can work with Artemis' archery skills to create some amazing combat combinations. And of course, Superboy can be an ally. His super - strength combined with Robin's powers can make for a formidable force against their enemies.
Obviously, the main character would be the one who would become Robin. But there could also be other important characters like his trainers or guardians. For example, an old martial arts master who taught him the ways of combat.
His friends like Batman and Nightwing could be main characters. Batman might use his detective skills to figure out what's wrong with Robin, and Nightwing could be there to offer emotional support.
One potential ally could be a wise old wizard from a magical dimension. They might have vast knowledge of the multiverse and help Robin navigate through different dimensions. Another could be a street - smart thief from a dystopian dimension. The thief's skills in sneaking around and getting out of tight spots could come in handy. And a friendly alien from a technologically advanced dimension could also be an ally, providing Robin with advanced gadgets and knowledge about different technologies.
A new super - villain group that wants to take over the world might be behind it. They figure that by experimenting on Robin, they can learn the secrets of the Young Justice and use that knowledge against them. Or perhaps an old enemy of Batman who wants to get back at him by harming his protege.
I'm not sure who Robin Cornell and Lisa Story specifically are. They could be ordinary individuals, or perhaps they are known in a specific community, workplace, or among a group of friends. Without more context, it's difficult to provide detailed information.
