Well, he may show his power by having an innate ability to understand and manipulate magic in ways that are beyond normal wizards. For example, he could be able to sense magic in objects or people in a much more detailed way, allowing him to uncover hidden secrets or foresee danger. He might also have a unique connection to some ancient and powerful magic source that gives him an edge in any magical encounter.
Well, in many such fanfictions, Harry might achieve power through intense magical training. He could study ancient spells and magic that others don't dare to touch. Maybe he discovers a hidden magical heritage within himself that gives him an edge. For example, he could find out that he has some connection to a powerful magical family from long ago that had unique powers.
One of his main opponents could be a dark wizard who challenges Harry's new - found power. This dark wizard might be jealous of Harry's abilities and wants to prove that he is the more powerful one.
Harry may show greater power in his connection to the magical world around him. He has always had a special bond with Hogwarts. In the fanfiction, this bond could be enhanced. So, when Voldemort tries to attack the school, Harry is able to draw on the magic of Hogwarts itself. He can use the ancient magic stored within the castle walls to create powerful shields and offensive spells that are far more potent than anything Voldemort can muster.
In some fanfics, Harry Potter might destroy the wizard economy by using powerful magic in a way that disrupts normal economic activities. For example, if he were to magically create an overabundance of a valuable resource like gold or a key magical ingredient, it could devalue it and throw the economy into chaos.
I think a really interesting powerful wizard in fanfic is a reimagined Severus Snape. In some fanfictions, he has powers that go beyond what we saw in the books. For example, he might have a hidden ability to communicate with magical creatures on a much deeper level. This could give him an edge in battles or in solving magical mysteries.
In a lot of Harry Potter fanfiction, Albus Dumbledore is often still considered one of the most powerful wizards. His vast knowledge of magic, his strategic mind, and his powerful spells make him a top contender. He was able to hold his own against the likes of Voldemort and also had a great deal of influence in the wizarding world.
Well, he might show Slytherin traits like cunning. For example, he could use clever manipulation to outwit his enemies, much like Slytherins are known for. He might also be more ambitious in this fanfiction, setting goals for himself that are self - serving rather than just for the good of all.
Fanfiction expands on the idea of a powerful wizard in the Harry Potter universe by imagining different origins of power. Some fanfictions might have a wizard gain power through ancient and forgotten spells, while others might have it as a result of a unique genetic inheritance. The way a powerful wizard is perceived by other characters is also explored. In some stories, other wizards are in awe of the powerful one, while in others they are jealous or fearful. Additionally, fanfiction can show how a powerful wizard's actions can have far - reaching consequences. For instance, a single spell cast by a very powerful wizard could change the entire political or magical landscape of the wizarding world, and these types of scenarios are often played out in fanfiction.
In many fanfictions, Harry Potter is made into a powerful wizard by being given new and unique magical abilities. For example, he might have the power of telepathy with all magical creatures. This allows him to communicate and gain their assistance, which makes him seem very powerful. He could also be shown as having a much deeper understanding of ancient magic than in the original series, enabling him to perform feats that are considered impossible in the normal wizarding world.
One possible fanfic could be about how Harry discovers new and unexpected powers of his wand. Maybe it starts with him accidentally using the wand in a way he never has before during a simple spell - like making a flower bloom in an extraordinary way that defies normal magic. This could lead to a journey of exploration as he tries to understand the true potential of his wand, perhaps with the help of Hermione and Ron.
