What are the common themes in 'Harry is a Metamorphmagus' fanfiction?

Identity is a common theme. Since fem Harry can change her appearance as a Metamorphmagus, she often has to grapple with who she really is. Is she defined by her looks or her inner self? Another theme is acceptance. How do the people around her accept or reject her because of her ability? For example, some might be jealous or scared of her power.

One common theme is changing the past. Since it involves time travel, the Metamorphmagus often tries to correct something that went wrong in the past or prevent a future disaster. For instance, they might go back to stop Voldemort's rise to power earlier in the timeline.

One common theme is self - discovery. Since Hermione suddenly has this new ability, she has to figure out who she is now and how this power fits into her identity. Another theme is the exploration of power. How much power does this give her? And how should she use it responsibly?

The metamorphmagus ability is a major plot device. It can create misunderstandings. For example, if Tonks changes her appearance suddenly, Harry might mistake her for someone else, leading to a whole chain of events. It also gives the writer the opportunity to explore themes like identity. Are Harry and Tonks the same people when they change their forms? How does this affect their relationship and the overall story arc? These are all things that can be explored through their metamorphmagus abilities.

One great fanfiction could be about Tonks using her Metamorphmagus abilities to go undercover in the Death Eater ranks. She could change her appearance to look like one of them and gather crucial information for the Order of the Phoenix. This would add an exciting element of espionage to the story.

In fanfiction, a female Harry Potter as a Metamorphmagus could have a very different Hogwarts experience. She might use her power to get out of tricky situations in classes or during Quidditch matches. Also, her relationships with other characters like Hermione and Ron could be affected. Hermione might be even more curious about the magic behind her Metamorphmagus ability, and Ron could be either in awe or a bit jealous.

There's also 'Metamorphmagus Fem Harry: A New Perspective'. This one delves deep into how fem Harry's Metamorphmagus nature changes her perception of herself. She struggles with the idea of a constantly changing self, and how others perceive her. It's a very character - driven story that shows a different side of the Harry Potter universe with this unique take on the character.

A common plot is using her Metamorphmagus ability for espionage. She could infiltrate Death Eater meetings or other dark wizard groups. Another plot could be centered around her trying to master this ability, which might be more difficult for her as she also has to deal with the normal challenges of being Harry Potter. For example, she has to study for her O.W.L.s and N.E.W.T.s while also learning to control her shape - changing.

There's a fanfiction called 'Tonks and Harry's Adventure'. It's set in an alternate universe where Harry has been a metamorphmagus all along, and Tonks is his mentor. They go on a journey to discover the origin of their unique magic. And then there's 'The Shifting Alliance' which delves into how Harry and Tonks use their abilities to fight against dark wizards in a new kind of magical war.

One possible reason could be copyright issues. The 'Harry Potter' franchise is very protective of its intellectual property, and fanfiction might sometimes cross the line in terms of using their concepts too freely. Another reason could be to maintain the integrity of the original story's lore. Since metamorphmagi are a specific part of the 'Harry Potter' world, perhaps some fanfictions were distorting or misinterpreting this concept in ways the rights holders didn't like.
