Character consistency. A good Percy Jackson headcanon fanfic keeps the characters true to their original personalities. For example, Percy should still be brave and a bit of a smart - aleck, and Annabeth should be intelligent and strategic. If the characters act out of character, it just doesn't feel like a Percy Jackson story.
A great Percy Jackson headcanon fanfic I recall is the one where all the demigods have a special mark on their body that represents their godly parentage in a more detailed way. For example, Percy had a trident - shaped mark on his back that glowed when he was near water. This added a really cool visual element to the story and also led to some interesting plot points, like when the demigods had to hide their marks from mortals or use them to prove their identity to other demigods.
One interesting concept could be alternate family relationships. For example, a headcanon where Percy has a long - lost sister who also has demigod powers. This could add new dynamics to his story and how he copes with family issues in the demigod world.
In visual novels, 'be' is short for bad ending which is an important aspect. It gives a different flavor to the overall narrative experience. A 'be' can shock the player, make them sad or disappointed, but also makes the story more memorable. Regarding 'ne', I'm not really sure. It could be a unique term in some indie visual novels or a local jargon within a specific community of visual novel enthusiasts. It might also be a typing error where someone meant to type something else like 'new' or 'net' in relation to the visual novel's online or updated content.
I'm not entirely sure what specific fanfiction you're looking for with this title. It could potentially be a story where the energetic Naruto dance is somehow combined with the unique style of 2NE1 in a fictional scenario. Maybe it's about a character from Naruto who is a huge 2NE1 fan and starts doing their own version of the Naruto dance inspired by 2NE1's music.
Well, in fanfiction, it often gives characters more backstory. For Percy, it might explore his life before he knew he was a demigod more deeply. Maybe he had some experiences as a child that influenced his later heroics. This helps to make the character more three - dimensional.
Maybe it's because they want to add depth and complexity to the characters. By giving them mental disorders, it can make the characters more relatable or interesting in some way.
One characteristic is that it often blends the distinct musical styles of BigBang and 2NE1. For example, in some fanfics, they might create a supergroup in the story that combines their rap, singing, and performance styles. Another is that it usually focuses on the relationships among the members. It could be friendships or even romantic relationships in a fictional sense.
One characteristic is the exploration of different musical styles. Since both BTS and 2NE1 have distinct musical identities, fanfics often blend their styles in creative ways. For example, a fanfic might describe a new song that combines BTS's rap - heavy tracks with 2NE1's edgy pop sound.
