Who are the most interesting characters in Fate Zero light novels?

Kiritsugu Emiya is quite interesting. His cold - blooded yet ultimately well - intentioned approach to the Grail War sets him apart. He's willing to do whatever it takes to win, even if it means using morally ambiguous tactics. Another is Gilgamesh. His arrogance as an ancient king and his overpowering abilities make him a captivating character. And then there's Saber, with her sense of honor and the internal conflict she has between her past as a king and her current role as a Servant.

Saber is one of the most interesting characters. Her complex backstory as King Arthur, a female in a male - dominated role, and her struggle with her ideals of kingship make her stand out. Another interesting character is Gilgamesh. His extreme arrogance and his view of himself as the ultimate being are fascinating. He also has a deep understanding of power and the nature of the Grail War.

Subaru is definitely one of the most interesting. His ability to return by death makes his journey full of twists and turns. Every time he dies and restarts, he has to face new challenges and figure out how to use his knowledge from previous loops to change things.

Kiritsugu Emiya is an engaging character. His methods are often extreme as he tries to win the Holy Grail War for what he believes is a greater good. He is a morally ambiguous character, willing to do things that others might consider unethical. Also, Irisviel von Einzbern is interesting. She is caught in the middle of the war as a tool of the Einzbern family, yet she shows great strength and kindness.

Well, Homura is quite an interesting character. Her combat skills and her mysterious past add to her allure. She has a strong sense of loyalty towards those she cares about. Then there's Witch. She's an old - time character with a lot of knowledge and power. Her relationship with the other characters, especially how she mentors them at times, is really engaging. And don't forget about Weisz. His technological skills and his growth as a person over the course of the story are things that make him a fascinating character.

One of the most interesting characters is probably Yue. Her mysterious past and her unique abilities make her stand out. She has a certain charm and her relationship with the protagonist is also quite engaging.

Chiaki Nanami is an interesting character. She has a unique way of looking at things and her presence often changes the dynamics among the characters. She is smart and has a certain innocence that makes her stand out in the rather dark world of the novel. Also, Mukuro Ikusaba is fascinating. Her backstory and her role in the events of the novel are full of mystery and intrigue.

Louise is very interesting. Her short - temper and insecurities as a mage, especially being known as the 'Zero' no Tsukaima, make her character complex. She has to constantly prove herself in a world that looks down on her initial lack of magical talent.

The main character, who is also a Master in the Holy Grail War, is interesting as well. He has to navigate through the dangerous and complex world of the Grail War, dealing with the powerful Servants and other Masters. His growth throughout the story, from being a relatively inexperienced person to someone who can hold his own in this cut - throat world, is a great aspect of his character.

I think Mordred is quite interesting. She is King Arthur's 'son' and has a complex relationship with her 'father'. Her rebellious nature and strong combat abilities make her stand out. Another interesting one is Jeanne d'Arc. She plays a crucial role in the story, trying to bring some sort of balance between the warring factions.
