The fanfiction often combines the magic system from the Harry Potter world with the TF TG concept. So, you get to see how transfiguration spells might be used to create these unique transformations. It also allows for different interpretations of the characters' personalities in their new forms.
In some Harry Potter TG fanfiction, Neville could be transformed into a powerful magical plant. This would give him a whole new set of abilities and a different role in the fight against the dark forces. He could use his new plant - like form to sense danger, communicate with other plants in the Hogwarts grounds, and perhaps even use his roots to trap dark wizards. There are also fanfictions where Draco Malfoy is transformed into a Muggle - like form, which makes him lose his pure - blood wizard superiority complex and forces him to see the world from a different perspective.
Ron could also be a main character. His loyalty and sometimes clumsy nature might get him into some interesting situations in the 'harry potter fairy tg fanfic'. For example, he might accidentally trigger a fairy - related magic that causes chaos in Hogwarts, and then he has to help fix it with his friends.
Magic and its role in the transformation is also a big theme. Since it's set in the Harry Potter universe, the use of magic to cause or deal with the TG transformation is central. Some fanfics explore how different spells or magical artifacts can be involved in the process, and how the characters interact with the magical side of their new situations.
One common theme is identity exploration. For example, when a character is transformed, they often have to figure out who they are in their new form. Another theme is friendship. The transformed character's friends may have to accept and help them through the changes. Also, there's the theme of adapting to new situations. Just like in the original Harry Potter series where students adapt to Hogwarts, in TG fics, the transformed character has to adapt to their new state.
