There are also some reoccurring eldritch beings that are popular. Cthulhu himself, of course, is a central figure. But other entities like Nyarlathotep, who often takes on different forms and messes with the minds of mortals, can be really interesting characters in fanfic. Their otherworldly and often unpredictable nature makes for great storytelling.
The investigator characters are often very popular. They are the ones who brave the terrors of the Cthulhu Mythos. For example, a detective - type investigator who uses his deductive skills to try and solve the mysteries while being constantly on the verge of losing his sanity.
Roland Carter is quite popular. He often appears as a tenacious investigator, bravely facing the terrors of the Cthulhu Mythos.
There could be other characters like cultists who play important roles in the 'Call of Cthulhu 2018 game story'. The cultists are usually the antagonists, trying to bring about the rise of Cthulhu. And there might be some locals in the game world who either help or hinder the investigator with their knowledge or actions.
I'm not sure specifically as I haven't read it, but likely there are investigators. These could be people with different backgrounds like a detective, a scholar, or a journalist, all drawn into the mystery of the Cthulhu Mythos.
One of the most popular characters is often the tough and battle - hardened sergeant. He's the one who gives orders, has a wealth of combat experience, and is respected by his men. For example, Sergeant Johnson in many fanfics is seen as a leader who can get his squad through any tough situation.
Ender is definitely one of the most popular. Since he's the main character in the original story, a lot of fanfic focuses on him, maybe giving him new adventures or exploring his emotions further. Another popular character is Valentine. She has a complex relationship with Ender, and fanfic writers like to delve into that more. And Petra is also popular as she was one of Ender's closest friends and comrades in Battle School.
The mysterious sages or scholars who have deep knowledge about the scrolls are also popular. They can offer wisdom and guidance to the main characters. They usually have a backstory full of years of study and discovery related to the scrolls, which makes them interesting. For instance, an old wizard who has spent his life deciphering the secrets of the scrolls.
The Guide is also well - liked. He is the first character that players usually interact with in the game, and in fanfics, he can be made into a mentor figure. He could be the one who trains new heroes, teaching them the basics of combat and survival in Terriria.
Often, the main hero character who has a special connection to the runes is quite popular. Maybe it's someone who can use runes in unique ways. Also, the wise old mentor figure who teaches about runes is usually liked.
Ruby Rose is often a very popular character. Her determination and her unique scythe - wielding skills make her stand out. She's also the leader of Team RWBY, so she has a central role in many fanfic storylines.
Daenerys Targaryen is often a popular character in fanfics. Her journey from an exiled princess to a powerful dragon - rider makes her a very appealing character to write about. Writers can explore different paths for her, such as what if she had allied with different houses or made different decisions regarding her dragons.
