They are not appropriate. Marvel is a global phenomenon with a large and diverse fan base. The official Marvel content is designed to be suitable for a broad audience. Fanfiction 'lemons' that are sexual in nature violate this principle. They can also create a negative perception of the fan community if they become too prevalent, as it gives the impression that the fandom is more about inappropriate content rather than the positive aspects of the Marvel universe like the characters' growth, their battles against evil, and the exploration of moral and ethical themes.
Lemons in Marvel fanfiction usually refer to stories that contain sexual or adult - themed content. However, this goes against the official Marvel universe's family - friendly nature and is often not in line with the intended spirit of the characters.
Lemons in fanfiction typically mean steamy or intimate scenes. They add a certain level of intensity and can explore the romantic or sensual aspect of the characters' relationships. But it's important to note that not all fanfictions contain lemons, and their presence depends on the author's style and the intended audience.
Well, first you need to have a clear idea of the characters and their relationship. Then, build up the tension and passion gradually. Don't rush the intimate scenes.
One might find great lemons in 'One Piece' fanfiction too. Given the vast array of characters and their diverse personalities, there are numerous opportunities for creative fanfiction. Some of the best lemons in 'One Piece' fanfiction might involve the more romantic or tense relationships, like the relationship between Luffy and Nami in some alternate universe fanfictions where their relationship takes on a more adult - like and complex nature.
It's not appropriate at all. Fanfiction is a great way to expand on the stories and characters we love, like those in the Akatsuki. But when it involves 'forced' situations and sexual 'lemons' content, it goes against the principles of good writing and respect for the characters. It should focus on positive aspects such as character development, new storylines within the Naruto world's context, and healthy relationships among the characters.
