If in the fanfiction, Harry's Metamorphmagus abilities are more of a curse than a gift at first. Hermione would be the one to help him control it. This shared struggle would bring them closer together in a more complex way. They would have to rely on each other more, not just for academic or adventure - related things, but also on an emotional and magical level.
In a Metamorphmagus Harry and Hermione fanfiction, their relationship might develop differently if the ability makes Harry an outcast in some way. Hermione, being the loyal friend she is, stands by him. This could lead to a more protective and perhaps even a romantic relationship. As she defends him from those who fear or misunderstand his powers, they grow closer. And over time, Harry might start to see Hermione in a new light, not just as a friend but as someone he can't live without. This would be a slow - burn type of relationship development that is different from the canon.
Well, their relationship could become more of a rivalry. Instead of being friends, they could compete with each other to solve the mysteries around the Goblet of Fire. Each trying to outwit the other in finding out who put Harry's name in the Goblet.
Their relationship could develop into a more competitive one. Instead of always being partners, they become rivals in certain aspects, like in academics or in a new magical sport at Hogwarts. This would add a new dynamic to their interactions.
In some fanfictions, Harry's newly - discovered metamorphmagus abilities are portrayed as more raw and uncontrolled compared to Tonks'. For example, in 'The Uncontrolled Shift', Harry has a hard time adjusting and often shifts involuntarily, while Tonks has had years to master hers.
In many of these fanfictions, their relationship often becomes more intense and reliant. For example, in stories where they are facing the mystery of Riddle together, they learn to trust each other even more deeply. They might start to rely on each other's unique skills, like Harry's courage and Hermione's intelligence, in a more profound way.
In their friendship, they were more like comrades. But as betrothed, there would be a new level of intimacy. They might start to notice little things about each other in a more romantic way. For example, Harry might be more aware of Hermione's beauty when she's reading, and Hermione might find Harry's leadership in a different light, seeing it as a quality for a future partner.
The relationship could also develop through a series of misunderstandings and reconciliations. They might misinterpret each other's actions at first, leading to some tension. But as they clear up these misunderstandings on the train rides, they grow closer. Eventually, all the pent - up emotions lead to that kiss on the train as a way of finally expressing their true feelings.
There are some great ones out there. Some fanfictions might explore how Hermione's new ability as a Metamorphmagus affects her relationships at Hogwarts. For example, it could add a whole new dynamic to her friendship with Harry and Ron. Others might focus on how she uses this ability to solve mysteries or get out of tricky situations that she wouldn't be able to otherwise in the regular Harry Potter universe.
In the original series, Harry and Hermione are friends. But as the Dark Lord and Dark Lady, their relationship would be much more complex. They might have a more equal partnership in terms of power. Instead of Harry being the main hero and Hermione as his sidekick, they would both be leaders. Their relationship could be based on mutual ambition and a shared vision for a new wizarding world.
One popular plot twist could be that Harry, as a Metamorphmagus, uses his ability to secretly protect Hermione in dangerous situations. For example, he might transform into someone unexpected to outwit the bad guys who are after Hermione.
