Well, in some fanfictions, dementor powers are extended to include mind - control over a larger scale. They might be able to not only suck out happy memories but also implant false ones. This could create really complex and dark storylines where characters are manipulated in more insidious ways.
Well, in certain fanfictions, the Dementor's Kiss is often explored in relation to a character's hidden past or secrets. Maybe a character who was supposed to receive the Kiss actually has a dark past that the Dementors are drawn to, but this also gives them a strange power to resist it. It can also be used as a way to explore the nature of the soul in the Harry Potter universe more deeply.
Well, perhaps Harry could have the power of elemental magic. For example, he could control fire, water, air, and earth, which would make his battles against Voldemort even more epic. He could also have the power of healing magic that is so strong it can even revive the dead, but this would come with great moral dilemmas. He might have to decide whether to use this power and disrupt the natural order of life and death.
In fanfiction, Harry Potter's hidden power could be related to ancient magic passed down through his family. For example, he might have the ability to communicate with long - dead wizards who could give him advice on how to defeat Voldemort. Another idea could be that he has a hidden power of persuasion that allows him to turn even the darkest Death Eaters to his side. Also, some fanfictions might explore that his hidden power is the ability to manipulate time in a more complex way than just using the Time - Turner.
One possible plot could be a story where a wizard discovers that Dementor blood has some unique magical properties. Maybe it can be used to create a powerful potion that has the ability to temporarily nullify the effects of dark magic. For example, a character is cursed, and the Dementor blood - based potion is the only thing that can save them.
It could be due to a blood - magic related incident. Suppose there is some long - lost connection between Harry's family and the origin of Dementors. A spell or a ritual that awakens this connection might endow Harry with Dementor - like powers. For example, if there was an ancestor who was involved in the creation of Dementors in some way, and that knowledge or power was passed down in a latent form in Harry's blood.
He might be feared by others. Since Dementors are known for their terrifying and soul - sucking abilities, people would be very cautious around Harry. His friends might even be initially scared of him until they understand he can control these powers.
One interesting plot could be a new character with a special power to repel Dementors. This character might be an outcast in the wizarding world at first but then becomes crucial in a major Dementor attack on Hogwarts. They could use their power in a unique way, like creating a shield of positive memories that not only protects themselves but also those around them.
One cool power often seen in such fanfiction is teleportation. This allows characters to quickly move from one place to another, escaping danger or arriving at crucial moments just in time. There are also powers related to healing, where a character has an extraordinary ability to cure any injury or illness, which can be very useful in the often - dangerous wizarding world.
It could also have the power of dark concealment. Dementors are known for their ability to blend into the darkness and appear unexpectedly. Their blood might be used in spells or charms that allow a wizard or witch to move undetected in the shadows, similar to how Dementors move. However, this power would likely come with a cost, as using dark - based substances often has negative consequences in the wizarding world.
Some writers make dementor powers more psychological. Instead of just sucking out happy memories physically, they can make it so that the dementors can influence a person's thoughts and make them doubt their own happy memories, as if the memories are being corrupted from within.
