Most likely Giovanni is one of the main characters, since his name is in the title. But there could also be other characters from the Assassin's Creed universe that interact with him in the story.
Giovanni would obviously be one of the main characters. There might also be other assassins he is associated with, like Ezio. His family members could also be main characters if the fanfic focuses on his personal life.
One interesting aspect could be the unique interpretations of the Assassin's Creed world. It might show Giovanni's character in new lights, perhaps his relationships or his skills in a different perspective.
Well, this fanfic could be a deep exploration of Giovanni's character. It may delve into his thoughts, his beliefs, and what drives him to be an assassin. It could tell the story from his perspective, showing his struggles, his triumphs, and his moments of self - discovery. It might also create new scenarios for him to face, outside of the main game plot, which could further develop his character and give readers a fresh view on this important figure in the Assassin's Creed franchise.
Connor is likely to still be one of the main characters. He was central in the original game and in the rewrite fanfic, his story could be expanded or changed in interesting ways. Haytham Kenway might also be a main character. His relationship with Connor, which was complex in the original, could be further explored in the rewrite. And there could be other characters like Achilles Davenport who play important roles as well, guiding Connor in his journey as an assassin.
In addition to Izuku, there could be his friends from 'My Hero Academia' who somehow get involved in the Assassin's Creed world. For example, Bakugo might end up there too and have a rivalry with Izuku in this new setting.

One common theme is probably the exploration of different historical periods. Giovanni gets to experience times he otherwise wouldn't, like maybe the Middle Ages or the Renaissance in a different light.
A unicorn pony could be a main character. They already have magical abilities which could be enhanced with Assassin's Creed - like skills. For example, their magic could be used for stealth or to create distractions, much like an assassin would use tools. Another option could be a pegasus pony. Their ability to fly would give them an advantage in terms of mobility, similar to how assassins move around rooftops and in high places in the Assassin's Creed games.
In 'Assassin's Creed: Renaissance', Ezio Auditore is a main character. He is an Italian nobleman turned Assassin. His journey from a young man seeking revenge to a master Assassin is really captivating.
