Definitely Alina Starkov. She is the heart of the story. Her transformation is not only about gaining power but also about growing as a person. She has to deal with the expectations that come with her newfound abilities. Then there's Genya. She is a Grisha who has her own secrets and insecurities. Her relationship with Alina is complex and adds depth to the story. And we can't forget Nikolai. He is a charming and resourceful character, with his own plans and ambitions that often intersect with Alina's story.
I think Kaz Brekker from the Six of Crows part of the Shadow and Bone universe is extremely interesting. He's a criminal mastermind, with a tragic past that has shaped him into a shrewd and calculating person. He's able to plan elaborate heists and outwit his enemies. Nina Zenik is also great. She's a Grisha with a big heart and strong powers, but she also has her flaws and insecurities. Jesper Fahey is a fun character too. His love for gambling and his sharpshooting skills make him stand out.
Mal is quite popular too. Fans often write about his relationship with Alina in different ways. Some might make their relationship stronger and more stable, while others might explore the idea of them parting ways. Nikolai is another beloved character in fanfiction. His charm and his role as a prince make him a great character to write about. Writers can focus on his adventures, his relationships with other characters, and his efforts to save Ravka.
The Darkling is a very popular character in Shadow and Bone fanfic. His mysterious nature, his power, and his morally ambiguous actions make him a great character to delve deeper into. Writers can explore his motives more fully, or create alternate versions of him where he makes different choices. Another popular character is Kaz from the Crows. His cunning and his leadership skills, along with his troubled past, are all things that fanfic writers like to play with.
The protagonist, of course. His dual nature of being a seemingly ordinary person on the surface but having this grand delusion (or perhaps not a delusion) of being an eminence in the shadow makes him extremely interesting. He constantly surprises the readers with his actions and plans.
The main character stands out as he maneuvers through the world in the shadows, his motives and actions often hidden from those around him. The female characters who interact with him also bring a lot of interest. They have their own personalities and goals and their interactions with the shadowy protagonist create complex and engaging relationships. Additionally, the villains in the story are interesting as they are often pitted against this unseen force, not fully aware of what they are up against.
Alina Starkov is a main character. She is an orphan who discovers she has special powers and becomes a very important figure in the world of Grisha. Another key character is the Darkling. He is a powerful and mysterious Grisha with his own agenda. Malyen Oretsev is also important as he is Alina's childhood friend and has his own role to play in the story.
Kate is also a fascinating character. She is intelligent and has a strong sense of purpose. She often takes the lead in trying to figure out the mysteries of the Shadow House. For example, she uses her wits to analyze the strange rules and phenomena they encounter, which shows her depth as a character.
Shadow is really interesting. He's a complex character who is thrust into this strange world of gods. His journey from being an ordinary man to being deeply involved in the godly affairs is captivating.
The female characters in the novel are also interesting. For example, the ones who gradually discover the true nature of the protagonist add depth to the story. They have their own personalities and goals, and their interactions with the protagonist create many engaging plot points. Some are strong - willed, while others are more naive, which makes for a diverse cast.
Cid is definitely one of the most interesting characters. His dual nature of seeming like a normal person but actually being a powerful eminence in the shadow is really fascinating. Then there's Alpha. She is very loyal to Cid and has her own set of skills and a mysterious past. Also, Beta is quite interesting with her own quirks and abilities.
