There are many interesting fanfictions about them. One common theme is their relationship development. Maybe they start as rivals, but gradually find common ground and develop a friendship or even something more. For example, in some fanfictions, they team up to face a common enemy in the Isle of the Lost, which makes them understand each other better.
A fanfiction might explore how Harry and Mal's relationship evolves after the events of Descendants 2. For example, Mal, now more in touch with her good side, tries to convince Harry to also look for a better way of life. Harry, initially resistant, slowly starts to see the value in what Mal is saying. Their interactions could be filled with tension, humor, and moments of real connection as they navigate their changing identities.
They can gain new perspectives on the characters. For instance, a fanfiction might explore a character's backstory in more detail than the original, which can make the character more relatable.
A great idea for a fanfiction could be a time - travel story where Harry and Mal are sent back to the past, perhaps to the days when their parents first met. They have to figure out how to get back to their own time while also dealing with the knowledge they gain about their families' histories and how it affects their relationship in the present.
One idea for a Mal and Harry fanfiction could be a story where they have to team up to face a new threat in the Isle of the Lost. Maybe a powerful and mysterious villain emerges, and they are forced to put aside their differences and use their unique skills to defeat the enemy. Mal's magic and Harry's cunning would make for an interesting dynamic.
One plot idea could be Harry Hook trying to find his true place in Auradon. He's used to being a villain but starts to question that identity. Another could be a love story where he falls for someone unexpected, like a goody - two - shoes Auradon student. Or perhaps a plot where he has to team up with his old enemies to save Descendants 2 world from a new threat.
One plot could be that Harry Hook discovers Mal's plan to bring more good to the Isle of the Lost, and at first he opposes it as he's used to the old ways. But as he sees the positive impact it could have on his friends, he starts to help her secretly. This creates a sort of 'enemies to allies' story.
A possible plot for a Descendants 2 Harry Hook OC fanfiction is that the OC is a healer on the Isle. Harry Hook gets seriously injured during one of his escapades, and the OC is the only one who can save him. This leads to a debt that Harry feels he owes the OC. As they interact more, the OC starts to influence Harry to think about a different life. Meanwhile, the OC has their own dreams of bringing some form of peace to the Isle, and Harry becomes an important part in making those dreams come true.
To create a believable OC, start with a backstory. Maybe the OC grew up in a different part of the Isle than Harry Hook, which gives them a unique perspective. Give them flaws, like being too trusting or having a quick temper. Also, think about their appearance. Do they have a signature piece of clothing or a distinct hairstyle? For example, they could always wear a torn red scarf that was a memento from their parents. Their goals and motives should be clear too, whether it's survival, revenge, or something else.
In Harry Potter fanfiction, there could be descendants of the main characters. For example, the descendants of Harry and Ginny might inherit their magical abilities and bravery. They could be involved in new adventures at Hogwarts or in the wizarding world, facing new threats like dark wizards emerging from the shadows. These descendants may also form new friendships and rivalries, just like their predecessors.
