In addition to Hannibal and Will, there could be new characters introduced. Maybe some other criminals who are either in awe of Hannibal's new level of deviousness or are trying to compete with him. Or perhaps some law enforcement agents who are specifically brought in to deal with the unique situation that Hannibal's 'great and gruesome height' has created. They would be the ones trying to outwit him and bring him to justice.
I'm not sure specifically as I haven't read the novel, but often in such novels there is a protagonist who has to navigate through the gruesome times. It could be a young person with unique qualities like courage or intelligence.
One character that would be interesting to include is Abel Gideon. He was already a part of Hannibal's world, and in a time - travel story, he could have a different role. Maybe he travels with Hannibal or is sent to a different time to hunt him down. Also, Freddie Lounds could be a great addition. She's always looking for a good story, and Hannibal's time - traveling would be the ultimate scoop. And then there are the victims. What if some of the victims from different time periods were able to come back and haunt Hannibal? That would add a spooky and interesting element to the fanfiction.
I'm not sure who the main characters are without reading it. It could be people with a passion for heights, like skyscraper builders or pilots.
Hannibal Lecter is the central and most iconic character. He is a brilliant and extremely dangerous psychiatrist with a taste for human flesh.
There was Hasdrubal, who was related to Hannibal. He also played an important role in the military campaigns against Rome. Another was Scipio Africanus. He was a Roman general who ultimately faced off against Hannibal and was a key figure in the Roman response to Hannibal's invasions.
Some characters like Jack Crawford might be dismissive. He is a no - nonsense FBI agent and might think fanfiction is just a waste of time and not in line with the real investigation and profiling work he does. So he would probably just roll his eyes and move on.
Ozpin is a great choice. His long - lived nature means he has a lot of knowledge about the Great War and could be in a position to influence the events, either directly or through his students.
They might be quite amused. For example, Will Graham might be intrigued by how others perceive his complex relationship with Hannibal. He could find some fanfictions that really dig deep into his psychological turmoil in a way that surprises him.
Most likely Merlin is one of the main characters. And probably there are some characters related to the dragoons, like their riders or leaders, but without reading the fanfiction it's hard to say for sure.
Well, it's hard to say for sure without reading the fanfiction. But it could be a young protagonist, perhaps a teenager, who is dealing with the typical problems of growing up like bullying or family issues. The story could then revolve around how they use time to heal from these difficulties.
