Well, a major theme is the struggle for acceptance. In these fanfictions, the immortal shapeshifter is often different from the normal inhabitants of the Naruto world. So, they have to deal with how others perceive them and try to find their place. Also, there's the theme of destiny. Given their immortality and shapeshifting ability, they might be seen as having a special role or destiny in the Naruto universe, which is often explored in these stories. Additionally, the theme of friendship and loyalty is common. They form relationships with Naruto characters and these relationships are tested due to their unique nature.
Well, there's a fanfiction called 'Immortal Shapeshifter's Adventure in Naruto'. In this story, the shapeshifter has the ability to not only change forms but also has some sort of immortality that sets them apart. They embark on a journey across the Naruto universe, meeting various characters and getting involved in different events. It's really exciting to read as it gives a fresh perspective on the Naruto world. There's also 'Naruto and the Immortal Shapeshifter Companion' which shows a great friendship between Naruto and the shapeshifter who is immortal.
One interesting aspect could be the new abilities Naruto would have as a shapeshifter. He could use this power to deceive his enemies in ways he couldn't before. For example, he could transform into an enemy ninja to infiltrate their hideouts.
Perhaps a group of rogue ninjas who are threatened by Naruto's shapeshifting ability. They might see him as a threat to their plans and try to eliminate him. They could be led by a mastermind who is well - versed in countering shapeshifting techniques.
It can create a lot of twists. For example, if a character with the shapeshifter bloodline is initially thought to be a weakling but then reveals their power, it can turn the whole plot around. They could infiltrate enemy groups by shapeshifting, which would be a great advantage for their side.
Well, in some Naruto shapeshifter bloodline fanfiction, the idea of a bloodline that enables the character to shapeshift into different elements is really cool. Imagine a character being able to transform into water to avoid attacks or into fire to launch surprise offensives. It gives a whole new dimension to combat and strategy in the Naruto world.
A long - lost relative of Sirius Black could be a shapeshifter. Since the Blacks had many secrets and were involved in a lot of dark magic in their family history, it would be believable for a hidden relative to have this unique ability.
One common theme is identity. Since the character can shapeshift, they often struggle with who they really are. Another theme is power and its consequences. Shapeshifting is a powerful ability and fanfics often explore how it can be misused or how it attracts unwanted attention.
The Children of the Forest are also common in shapeshifter fanfictions. They are already somewhat mysterious in the original series, and their connection to magic makes them ideal candidates for shapeshifting in fan works. Writers might have them shapeshift into different animals or even blend in with humans to protect their secrets or fight against their enemies.
One great Hermione is a Shapeshifter fanfic is 'The Shapeshifting Hermione'.
