Since I haven't read it, I can't say for sure. But it could be the usual suspects in DBZ like Goku, Vegeta, and Piccolo. They are often the main focus in many fanfics as they have complex personalities and are central to the DBZ story.
Well, 'between pleasure and pain dbz fanfic' could potentially be about the internal struggles of the characters. For example, a character like Vegeta might be in a situation where on one hand, he desires power which gives him a sense of pleasure, but on the other hand, the path to attaining that power is filled with pain, such as intense training or facing powerful enemies. It could also deal with the relationships between characters, like the pleasure of friendship but the pain of betrayal or loss within the DBZ universe.
A prevalent theme is sacrifice. Characters might sacrifice something they value (which causes pain) for a greater good or a deeper connection, and that in turn brings a different kind of pleasure. For example, a character might sacrifice their own comfort to help a friend in need. Another aspect could be self - discovery. The pain of facing one's flaws or insecurities can lead to the pleasure of truly understanding oneself in a 'between pleasure and pain fanfic'.
A 'between pleasure and pain fanfic' could be set in a post - apocalyptic world. The pain of survival, like finding food and shelter in a harsh environment, is contrasted with the pleasure of small victories, such as making a new friend or finding a hidden oasis. There might also be a story about a student who struggles with the pain of difficult academic work but experiences the pleasure of achieving good grades and the respect of teachers and peers.
Often, the main character is a self - insert type of gamer who gets transported into the DBZ world. They usually have the ability to use gamer - like mechanics to interact with the DBZ universe.
Love and sacrifice. Just like in the original Twilight series, love is a central theme. But in 'Between Pleasure and Pain' fanfics, it's often more complex, with characters having to sacrifice more for their love. For example, they might have to give up their own desires or face difficult choices that cause them pain.
I don't know for sure as I haven't read it. It could be the classic DBZ characters like Goku, Vegeta, or Piccolo. Maybe it focuses on a less - known character and gives them a chance to shine with this unburdened fury concept.
Typically, the main characters would include Goku. He's the central figure in most Dragon Ball Z related stories. Vegeta would also likely be a main character as he is one of the most important Saiyans. And of course, there would probably be Piccolo, who has been a key ally throughout the series. These characters are often at the forefront of the action, whether it's fighting powerful villains or seeking new levels of power.
Obviously Naruto would be one of the main characters since it's in the title. And probably some of his friends from the Naruto series like Sasuke or Sakura. Since it's combined with DBZ, there might also be characters from DBZ like Goku or Vegeta. They could either be allies or rivals to the godlike Naruto.
Asura is surely a main character in this fanfic. Besides, characters like Piccolo could also be important. Piccolo is a powerful and intelligent character in the DBZ universe. He might play a role in dealing with Asura's wrath, either as an ally or an adversary depending on how the story unfolds. Also, there's a good chance that other Saiyans like Gohan could be main characters as well, since they are key figures in the DBZ world and their reactions to Asura would be interesting to explore.
