The goddesses or gods in dungeon core fanfiction can be really popular. They might have a connection to the dungeon core, either as its creator or as a being interested in its development. There are also characters like the elemental spirits that can befriend the dungeon core and help it harness the power of the elements. For example, a fire elemental spirit might help the dungeon core create a lava - filled chamber. And of course, the mysterious merchants who appear near the dungeon, offering strange and valuable items in exchange for dungeon - specific resources, are also liked by many readers.
Well, in dungeon core fanfiction, the guardians of the dungeon are often popular characters. These could be powerful monsters that are bound to the dungeon core. They have a strong sense of loyalty and will fight to the death to protect the dungeon. Some fanfictions also feature wise sages who visit the dungeon to study its unique properties. They might give advice to the dungeon core or try to understand the secrets of its power. And then there are the thieves or rogues who try to steal from the dungeon, but their sneaky ways and narrow escapes make them interesting characters.
I don't know specifically since I haven't read this light novel. But typically, there would be the dungeon master as a main character. There might also be some important adventurers who are either friends or foes of the dungeon master.
One popular dungeon core web novel is 'Dungeon Born'. It has an interesting concept where the dungeon core evolves and defends itself. Another is 'The Primal Hunter' which also features dungeon - like elements in its story progression. And 'He Who Fights with Monsters' has some dungeon - related adventures as well.
The main character is, of course, the human who has been reincarnated as a dungeon core. Their past life experiences as a human shape their actions and decisions as a dungeon. There may also be some key adventurers who are constantly trying to raid the dungeon. They are sort of the antagonists from the dungeon core's perspective, but they also have their own backstories and motives.
One of the popular characters is often the Paladin. They are known for their righteousness and combat skills, often leading the group in battles against evil. Their code of honor makes them interesting to write about in fanfiction.
Naruto himself is often a very popular character. His high - energy and determination translate well into the D&D - inspired fanfiction settings. He can be seen as a sort of 'chaotic good' character, always looking to help others and break the rules when necessary. Sasuke is also popular as he has a complex personality and his Sharingan abilities can be very interesting to adapt into D&D - like power systems.
One interesting idea is the unique dungeon designs. In dungeon core fanfiction, dungeons can have all sorts of crazy layouts, like a floating island dungeon or a dungeon that exists in multiple dimensions. Another idea is the different types of dungeon cores. Some might be sentient and have their own personalities, which can lead to very different dungeon management styles. Also, the interaction between the dungeon and adventurers can be really cool. For example, a dungeon might play tricks on adventurers by creating illusions or changing the layout as they progress.
Well, definitely Makoto Naegi. He's the main protagonist in Danganronpa, and his character is really adaptable to different situations, including a D&D - style adventure. His determination and good - hearted nature make him a natural leader in any group. Then there's Byakuya Togami. His wealthy and haughty personality can bring a different dynamic to the story. In D&D terms, he could be like a noble - class character with access to a lot of resources. And Monokuma, that iconic bear from Danganronpa. Even though he's not a traditional 'good guy' character, his presence can add a lot of humor and chaos to the fanfiction. He could be like a mischievous deity or some sort of cursed entity in the D&D world.
Mew is frequently a popular choice. Since it's a mysterious and rare Pokemon, fanfiction writers can create all sorts of interesting backstories and roles for it. It could be a guiding spirit in the Mystery Dungeon, leading Pokemon to hidden treasures or helping them unlock special abilities.
Pikachu is often a popular character. Its well - known status from the main Pokemon series makes it easily recognizable and a favorite for many to include in fanfiction. Another popular one could be Charmander. Its evolution line is iconic, and in the context of a Mystery Dungeon Castle setting, it can bring a lot of action and adventure elements with its fire - type abilities.
Charizard is also quite popular. In fanfiction, it can be depicted as a powerful and somewhat arrogant Pokemon that has to learn to work with others in the mystery dungeon adventures. It often has to face challenges that test its strength and pride.
