Fanfic about Harry Potter turning into an animal: Any recommendations?

One interesting plot could be that Harry turns into a stag, just like his father's Patronus. He could then use this form to explore the Forbidden Forest in ways he couldn't as a human. He might discover hidden magical creatures or ancient secrets. Another plot could be that he turns into a cat and has to navigate Hogwarts corridors without being noticed by Filch. He could also use his new form to spy on Snape and find out if he's really up to no good.

One great fanfiction in this theme is 'The Animagus Adventures of Harry Potter'. In it, Harry discovers he has an even greater ability to turn into various animals and uses it to solve mysteries around Hogwarts. It's really exciting as it combines the magic of transformation with the existing Hogwarts lore.

One idea could be that as a girl, Harry has to deal with different social expectations in the wizarding world. For example, she might face more restrictions on certain adventures compared to when she was male. Also, her relationships with Ron and Hermione could change in interesting ways. Ron might be more protective, while Hermione could become a closer confidant as they share more 'girl - specific' experiences.

Another interesting concept is Harry turning into a cat. He could then slink around Hogwarts unnoticed. He could spy on Snape or Malfoy, gathering information. His cat form would give him the ability to be stealthy and get into small spaces, like the hidden passages in the castle.

There is a fanfic where James Sirius Potter discovers a hidden mystery in Hogwarts. In this story, he teams up with some new friends. The author does a wonderful job of creating a believable world and the relationships between the characters are really well - written. It's a great read if you want to explore more about this character.

I've read a fanfic where the female Harry Potter in the orphanage has a special connection to animals. In this story, she befriends a stray cat in the orphanage yard, and later discovers that the cat is actually a magical familiar sent to protect her. The orphanage setting in this fanfic is really well - described, with its dreary halls and mean caretakers. The story shows how her gender might lead her to be more empathetic and nurturing towards the cat, which in turn helps her unlock her magical abilities.

One great fanfic could be 'The Bond of Hogwarts' which features Harry Potter and Susan Bones. It delves into their relationship as they team up to solve a mystery within Hogwarts. They discover an old, hidden chamber that holds secrets about the founders of Hogwarts. In this fanfic, Susan's intelligence and Harry's bravery work well together, creating an interesting dynamic.

One great 'Harry Potter, Patil Twins' fanfic could be 'The Adventures of the Patil Twins and Harry Potter'. It focuses on their unique friendship and how they navigate through the challenges at Hogwarts together. It has some really interesting plot twists that involve their combined magical abilities.

One possible fanfic could be one where goblins in the Harry Potter universe use their magical skills to build rockets. Maybe they are trying to find a new magical realm or escape from some dark force. However, I haven't actually read such a specific fanfic. You could try searching on popular fanfic websites like FanFiction.net or Archive of Our Own.

One great 'Harry Potter Head of House fanfic' could be one where McGonagall has to deal with a new kind of magical threat within Hogwarts. It might show her using her wisdom and strictness to protect the students. Another could focus on Snape as the Head of Slytherin, delving deeper into his complex character and how he manages the Slytherin students with his own brand of tough love.
