In some fanfictions, it could be through intense magical training and study. Maybe he discovers an ancient spell or a hidden magical technique that allows him to assert control over the dangerous Fiendfire.
One consequence could be that it changes the power dynamics in the wizarding world. If Harry can control Fiendfire, he becomes an even more powerful wizard, which might make some people fear or envy him.
In fanfiction, if Harry Potter controls the dead, it could completely change the power dynamics in the wizarding world. It might give him an edge in battles, as he could summon the knowledge and skills of the deceased. For example, he could get strategic advice from great wizards of the past. However, it also raises moral questions. Is it right to use the dead in such a way? It goes against the natural order in the original Potter universe.
One way could be through telepathy. In fanfiction, Harry might be able to directly communicate with the minds of animals and tell them what to do. For example, he could tell a group of birds to fly in a certain pattern to create a distraction.
Well, it might be a really creative and out - of - the - box concept in fanfiction. It could be that the bugs are enchanted in some way, and Harry, being the hero, has the power to control them. This could be used for various purposes like spying, as bugs can go unnoticed in many places, or for combat, where a swarm of controlled bugs could be a formidable force against enemies.
In some Harry Potter fanfiction where there is control over werewolves, it often involves powerful magic. For example, the use of spells like the Imperius Curse might be a way to control werewolves in a non - traditional sense. However, this is a dark form of magic and is usually frowned upon in the wizarding world.
One example could be a story where Harry discovers he has the ability to control insects during a Hogwarts summer. He uses this power to spy on the Malfoys and gather information that helps the Order of the Phoenix. The insects act as his little spies, flying into windows and reporting back to him through a magical connection.
Maybe Harry discovers a new spell that allows him to control metal. He could use this power to defend Hogwarts. For example, he might be able to manipulate the metal gates to keep out dark wizards.
A possible plotline is that Harry accidentally discovers the time - controlling power while exploring an old, forgotten part of the Hogwarts library. He then has to figure out how to use it without disrupting the fabric of time too much.
Well, 'harry potter controls the heartless fanfiction' might imply that Harry Potter, as a character, is somehow in charge of a particular type of fanfiction that involves heartless characters. It could be that he is the central figure in this fan - created narrative, dictating how the story with heartless characters unfolds. For example, he could be using his powers to make these heartless characters act in certain ways that are important for the plot of the fanfiction.
