In Harry Potter fanfiction involving Dementor blood, what are the potential powers it might possess?

It could have the ability to communicate with Harry on a psychic level. Telling him when danger is near or guiding him on how to use its powers most effectively in different situations.

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.

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.

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 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.

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.

Well, as Zelena's son, Harry could have her power over fire, which she sometimes uses in her magic. He could also have the ability to communicate with animals, as Zelena has a certain connection to the natural world. Another power he might possess is the power of teleportation. Zelena is quite mobile in the story, and Harry could inherit this trait, allowing him to move quickly from one place to another. But it's also possible that his powers are a combination of Zelena's and some unknown latent magic within him, which could make his powers unique and unpredictable.

It would be really dark and mysterious. Harry as a Dementor Animagus would have some very different powers and abilities. He might be able to control the Dementors in a way, or use their fear - inducing abilities for his own purposes, perhaps in the fight against Voldemort. But it would also be a struggle for him to control his Dementor side, as Dementors are associated with negative emotions.

Well, it could be about a Harry Potter who has some special power over Dementors. Maybe he can control them instead of just fending them off with a Patronus. He could use this new - found power to his advantage in the wizarding world, like using Dementors to guard against dark wizards.

Another theme is the nature of darkness. Since Dementors are associated with darkness, fanfics often explore how the Dementor King embodies this darkness and how it affects the characters around him. They might look at how the characters struggle against this all - consuming darkness. For example, a character might have to find their inner light to resist the Dementor King's influence. It can also involve themes of redemption, as some stories may have the Dementor King or those influenced by him seeking redemption from their dark deeds. This adds a layer of complexity to the characters and the overall story.
