Well, 'harry potter is a pet familiar fanfic' could imply a fan - created story that plays with the concept of Harry Potter in an unusual way. Maybe in this fanfic, Harry has the characteristics of a pet familiar, like being able to communicate with his owner in a special way or having certain magical abilities related to being a pet in the wizarding world. It could be a really creative take on the Harry Potter universe by a fan writer.
I haven't actually read this specific fanfic, so I can't give exact plot examples. But it could be something like Harry is turned into a cat (a common pet familiar) and has to navigate Hogwarts in that form, trying to communicate with his friends without being discovered.
One idea could be that in a hidden corner of Hogwarts, a student discovers a baby dinosaur as their familiar. Maybe it was brought through a magical portal from a prehistoric era. The student then has to keep it a secret while trying to figure out how to take care of it.
In most of the official 'Harry Potter' lore, Harry is not Snape's familiar. However, in fanfic, the rules can be bent and rewritten. So it's possible in some very creative and non - canon fanfictions for this strange relationship to exist, but it goes against the general nature of their relationship in the original books.
Perhaps the fanfic could explore the idea of Cerberus being a familiar that helps Harry in his fight against Voldemort. Cerberus could guard important places for Harry, or even accompany him into battle. Its three heads could provide different forms of defense or attack, making it a very formidable ally for Harry in the wizarding war.
No. 'Harry Potter' is an original and highly popular book series, not a fanfic. Fanfic stands for fan fiction which is a work of fiction written by fans based on an existing work. 'Harry Potter' was created by J.K. Rowling and is a unique and original story with its own world - building, characters, and plotlines.
Yes, in many fanfics about Harry Potter, Severus Snape is often given a familiar. It could be used to add more depth to his character. For example, if his familiar was a black cat, it could symbolize his mysterious and somewhat dark nature. Fanfic authors often use familiars as a way to explore the relationships between characters and the magical world around them. So it's not uncommon to see Severus with a familiar in these creative works.
The plot could start with Harry stumbling upon Cerberus in a hidden part of Hogwarts. He feels an instant connection and decides to try and make Cerberus his familiar. This would be a difficult task as Cerberus is known to be very fierce. But Harry's kindness and his ability to understand magical creatures might win Cerberus over.
The wrong part is that Harry Potter is not a fanfic. It's an original creation. Fanfic implies that it is written by fans based on another work, but Harry Potter was written by J.K. Rowling as an original story with its own unique elements.
I haven't read a specific 'Harry Potter is a tiger familiar' fanfic myself. But when you search for it, look for ones that have detailed world - building. A good fanfic would not only focus on the concept of Harry being a tiger familiar but also integrate it well into the existing Harry Potter universe. For example, how does this new identity affect his relationships with Dumbledore, Hermione, and Ron? Also, look for fanfics with good grammar and spelling, as those are often signs of a more carefully crafted story.
If Harry had a dinosaur familiar, it would be a huge advantage in terms of protection. A large dinosaur could easily fend off most threats. For instance, a triceratops could use its horns to defend Harry from attackers.
