There should not be any. Fanfiction is supposed to be a creative outlet within the boundaries of legality and decency. The description in the title you provided is not in line with those values, so it's not something that would be considered suitable for all ages or even allowed in most proper fanfic spaces.
I'm not sure exactly as this seems like an inappropriate and unethical concept. Pokémon is a family - friendly franchise, and such a title goes against its intended nature.
To avoid such inappropriate fanfic, you can start by being selective about the sources you use. Stick to platforms that have a good reputation for maintaining a positive and clean fanfic environment. Look for tags such as 'fluff' or 'wholesome' which are usually associated with non - offensive content. Also, if you notice that a particular author consistently writes inappropriate stuff, avoid their works. And if you ever encounter a fanfic with a disturbing title like that, report it to the platform so that they can take appropriate action.
Definitely not. The original 'Beauty and the Beast' has themes of love, redemption, and self - discovery. Incorporating such lewd content into a fanfic is disrespectful to the source material and can be offensive to many fans who appreciate the pure and positive aspects of the story. It also violates the general standards of decency in literature.
I'm not aware of any official 'Harry Potter' fanfic with such a title. 'Harry Potter' fanfics usually have more positive and creative themes that are in line with the general spirit of the original series. Using inappropriate or vulgar terms in fanfic titles is not in line with the good-natured nature of most fan communities.
A common theme is also the exploration of power dynamics. Given Severus' position as a teacher and his knowledge, and Harry being the famous 'Boy Who Lived', when they are thrust together, there are interesting power plays. Sometimes Severus has the upper hand in knowledge and magical ability, but Harry has his own influence and moral standing that can shift the balance in their relationship.
No. Pokémon is a brand aimed at a wide audience including children. Such a title contains inappropriate and vulgar content that has no place in the Pokémon fan community.
One popular fanfic in this category could be 'The Unlikely Bond'. It explores a unique relationship between Severus and Harry in a rather interesting way. The story focuses on how they gradually come to understand each other better.
Sirius Black is a very common 'daddy' character. In the original story, he was Harry's godfather, so it's easy to expand on that relationship in fanfiction. He has the potential to be a loving and protective figure for Harry.
One popular one might be those that explore unique relationships within the wizarding world. For example, a story could revolve around a wealthy and powerful wizard taking a young, talented witch or wizard under their wing in a mentorship - like 'sugar daddy' situation. However, these types of fanfics often deviate from the original themes of the Harry Potter series and can be a bit controversial.
