Friendship is also a common theme. Harry's friends' reactions to his Animagus form can range from shock to admiration. And sometimes, his Animagus form can even strengthen his bonds with his friends. For instance, if he can use his form to rescue a friend in a tricky situation, it deepens their friendship.
One common theme is self - discovery. Harry (or other characters if they are the focus) discovers a new part of themselves through their Animagus form. It's like a journey of understanding their true nature.
One great 'Harry with Animagus form' fanfic is 'Harry's New Shape'. In this fic, Harry discovers he can transform into a majestic stag, much like his father's Patronus. It's really interesting to see how he uses this new ability in his adventures at Hogwarts and against the Dark forces.
In some fanfictions, Harry's animagus form could be a stag, similar to his father's Patronus. It would be a cool connection to his family heritage and his own magical abilities.
One common theme is self - discovery. Since becoming an Animagus is a big part of a wizard's identity in the fanfics, Harry often has to figure out what his Animagus form means for him and how it fits into his life. For example, he might learn something new about his personality or his place in the wizarding world through his Animagus form.
One common plot is Harry using his dragon form to surprise his enemies. He could swoop in during a battle and turn the tides. Another is that he discovers his animagus form while exploring some ancient magic in Hogwarts. It could be hidden in the Forbidden Forest or in a secret chamber.
One common theme is identity exploration. Harry has to come to terms with this new part of himself as a fox. Another is the use of his fox form for strategic purposes, like sneaking around Hogwarts.
In many of these fanfictions, a major theme is protection. Harry, as a wolf animagus, uses his form to protect those he loves. For example, he might patrol the Hogwarts grounds at night in wolf form to keep students safe from dark creatures. Another theme is identity. Harry has to come to terms with this new part of himself and how it fits into his overall identity as the Boy Who Lived. And sometimes, the fanfictions explore the connection between his wolf form and the ancient magic of the wizarding world, as wolves have often been associated with magic in folklore.
Friendship is also a big theme. His friends usually play a role in his journey to becoming a multi animagus. They might help him train or be there to support him when things go wrong. For example, Hermione could use her vast knowledge to assist Harry in understanding the complex magic involved. And Ron could be there for moral support.
One common theme is power. Since a kraken is a very powerful and mythical creature, fanfictions often explore how Harry harnesses this new power. Another theme could be secrecy. Harry would need to keep his kraken form a secret, so stories might revolve around the difficulties of doing so.
Friendship and alliances are often themes. When Harry is in a crossover situation, he has to form new friendships and alliances. His Animagus form can sometimes be an advantage in making these connections, as it can make him seem more relatable or trustworthy to certain characters from other universes.
