The fanfic could explore the relationship between Harry and his pet snake. Harry might have to hide the snake from some people at first because they are afraid of snakes. But as time goes by, the snake proves itself to be friendly and useful. It could also have a unique name that has some special meaning in the wizarding world, and the snake might play a crucial role in a big event in the story.
In the fanfic, perhaps Harry's pet snake is a rare species. He found it in a mysterious place. The snake might be really intelligent and can understand complex commands from Harry. It could be his loyal companion, always by his side when he faces difficulties at Hogwarts or outside.
Well, it could be that Harry's snake has some magical powers. Maybe it can communicate with other magical creatures secretly. It could help Harry in his adventures, like finding hidden passages or warning him about danger.
The snake might help Harry in his search for Horcruxes. It could use its unique senses to detect the presence of dark magic associated with the Horcruxes. For instance, it could lead Harry to a hidden location where a Horcrux is concealed.
One possible plot could be that the pet snake animagus is actually a reincarnation of an ancient wizard. Harry discovers this when the snake starts showing signs of intelligence and knowledge beyond what a normal snake should have. They form a unique bond and the snake helps Harry understand some of the more obscure parts of magic. The snake could also have enemies from its past life, which now target Harry, leading to a series of adventures where Harry has to protect both himself and the snake while also trying to uncover the snake's true past and how it can help in the fight against the dark forces.
In some fanfictions, the snake could be a magical gift from a mysterious wizard. Maybe it was given to Hermione because she showed great potential in handling magical creatures.
There probably are. Fanfic writers love to explore different ideas within the Harry Potter universe. A story where Harry has a pet snake animagus could be really interesting. It might involve new magical abilities or adventures related to the snake form. However, it could also be a bit of a challenge to fit into the existing lore, but that's the fun of fanfiction.
Maybe it's an anonymous gift from someone who has been observing Harry. This person could be a former student of Hogwarts who has a special connection to snakes and sees that Harry has a kind heart and would take good care of the snake. So they leave the snake for Harry to find with a simple note that just says 'For Harry Potter'.
In this fanfiction, Harry might find the snake in the Forbidden Forest. The snake could be a magical one with special powers, like being able to communicate telepathically with Harry. It could help Harry in his adventures, for example, by warning him of danger in the school corridors.
The snake could help Harry find his way around Hogwarts. You know, Hogwarts is a huge and complex place. The snake might be able to sense the different magical auras of different areas and lead Harry to where he needs to go, like the library when he has to study for an important exam or the Room of Requirement when he's in a tight spot.
The dragon could help Harry in battles. For instance, in a fight against Voldemort's Death Eaters, the dragon's firepower would be a great advantage.
In fanfiction, Harry Potter could have a phoenix as a pet. A phoenix is a very magical and majestic creature. It can be a great companion for Harry. It has the ability to heal itself by bursting into flames and being reborn from the ashes, which could be useful in many dangerous situations Harry might face.
The girl could take her pet snake to school for show - and - tell. Her classmates might be scared at first, but then become interested as she explains about the snake's habits. Or the snake could escape from its cage and the girl has to search all over the house to find it. Maybe it ends up in the attic or under the bed.
