There might be some 'harry is snape's slave' fanfiction out there, but it's not a very common or positive trope in the Harry Potter fan community. Such a premise goes against the characters' relationships as portrayed in the original books. If you do look for it, make sure to check the ratings and reviews on the fanfiction platforms to ensure it's something you want to read.
The 'harry is snape's slave' fanfiction concept is quite disturbing. In the original Harry Potter series, Harry and Snape have a complex relationship that is based on mutual suspicion, grudges, and ultimately some understanding. Reducing Harry to a slave in fanfiction is a rather extreme and untrue-to - the - spirit - of - the - series interpretation.
In some 'Snape slave to Harry fanfiction', the plot might start with a prophecy or a magical bargain. Maybe a seer predicted that only with Snape as Harry's servant could a great evil be defeated. So, Snape, bound by this fate, has to follow Harry's commands. Along the way, they face many challenges together. Harry has to deal with the power imbalance and Snape has to struggle with his pride. Their relationship evolves from one of forced servitude to a more complex bond of respect and cooperation as they fight against the forces of darkness.
I remember reading 'A New Dynamic' which is a great 'Master Harry Slave Snape' fanfiction. It really plays on the idea of them being in such opposite roles. Harry's character growth as he tries to handle Snape in this new relationship is really well - written, and Snape's begrudging acceptance of his situation makes for an engaging read.
At first, the relationship might be filled with tension. Harry would be resentful of being in a slave - like position to Snape. But as time goes on, he realizes that Snape has a depth of knowledge and a hidden agenda that might not be as bad as he initially thought. Snape, on the other hand, might start to see Harry not just as a tool or a burden, but as someone with potential that he can shape in his own way.
I think it's a rather strange and disturbing concept. Harry Potter is a story about heroism and good vs evil, not slavery. This idea goes against the values of the original series.
There are countless fanfictions out there, and while I can't point to a specific 'Snape slave to Harry fanfiction', here's how you can find a good one. Firstly, go to big fanfiction communities like Archive of Our Own or Fanfiction.net. Use their search functions to look for fics with 'Snape' and 'Harry' in the title or tags. Read the synopsis carefully. Some might explore a really unique dynamic between the two characters, where Snape is in a subservient position to Harry. But be prepared for a wide range of interpretations and writing qualities. You might have to dig through a few not - so - great ones before you find a gem.
The role reversal is a big part. We're so used to seeing Snape as the strict teacher and Harry as the student. So when Harry is the master and Snape is the slave, it's a complete turnaround. It allows for new interpretations of their characters and their relationship.
I haven't come across a 'snape is sirius slave' fanfiction myself. Fanfiction themes can be very diverse, but this one seems rather unorthodox and might not be as common. However, the world of fanfiction is vast, and new works are being created all the time, so it's possible that someone has written it, but it may be difficult to find.
There could be. Main features might include a distorted view of the relationship between Harry and Snape. It might show Harry in a position of complete subservience, which would change his character drastically from the original. Snape's character might also be warped, as in the original he was a complex figure with his own motives and loyalties. This kind of fanfiction would likely shock many fans who are used to the more positive and growth - oriented relationships in the official books.
