One of the best SNK fanfics could be those that focus on the backstories of the characters. For example, a fanfic that delves deep into Levi's past before he joined the Survey Corps. It might explore his life in the underground and how he developed his combat skills. Another great one could be about Eren's internal struggle in a more detailed and alternative way than in the original story. There are also fanfics that explore different relationships between the characters, like a friendship - centric story between Armin and Mikasa that shows their bond growing in unique circumstances.
One characteristic could be its unique art style. SNK is known for its distinct visual aesthetics, which are likely to be carried over into the visual novel. Another might be its storytelling. It could potentially have complex and engaging plots, perhaps with elements of mystery or action.
One common theme is power struggle. When characters from different universes meet in a crossover, they often have different levels of power. For example, in a crossover with a superhero universe, the SNK characters might have to deal with the much greater powers of the superheroes, leading to a power struggle.
A vivid description can also make a great novel opening. Such as 'The sun blazed down on the dusty town, the heat rising in shimmering waves from the cracked streets. The saloon doors swung open, and a figure emerged, his face hidden beneath a wide - brimmed hat.' This type of opening sets the scene and makes the reader curious about what will happen next. It gives a sense of place and a hint of mystery.
Beginning with a vivid description can be great. Like in 'The Great Gatsby' where it starts with 'In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since.' It gives a sense of the narrator's voice and draws you into their world.
One of the best openings is from 'Pride and Prejudice' by Jane Austen: 'It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife.' This line immediately sets the tone for the story which is centered around marriage and social status in 19th - century England.
One great opening is to start with a thought - provoking question. For example, 'Have you ever wondered what it would be like to live in a world without colors?' This immediately grabs the reader's attention and makes them curious to find out more. It sets the tone for a story that could be about a world where something fundamental has been altered.
