There are also fanfictions where a new, original character is introduced as the strongest being. This character might be a descendant of an ancient and powerful magical family that has been in hiding for centuries, and they possess a unique form of magic that makes them invincible in the wizarding world.
Some fanfictions portray a super - powerful Dumbledore. He could have even more extensive knowledge of ancient and lost magics, and his power could be so great that he can manipulate time and space, and protect the wizarding world from threats that are far greater than Voldemort.
In many Harry Potter fanfictions, characters like an all - powerful and magically enhanced Harry Potter himself are often depicted as one of the strongest beings. He might have mastered all kinds of magic way beyond what was shown in the original books and can defeat the most powerful dark wizards with ease.
Powerful magic skills are a key factor. For example, if a character can perform extremely advanced and dangerous spells without any effort, like the Unforgivable Curses but with even more potency, they can be considered very strong. Also, the ability to control powerful magical creatures is a sign of strength.
Hermione Granger could also be considered a very strong disciple in fanfiction. She is highly intelligent and has a thirst for knowledge. In fan - made stories, she might use her intelligence to develop new spells or magical techniques, making her a force to be reckoned with. For example, she could find ways to combine different branches of magic in unique ways that give her an edge in battles or magical problem - solving.
In a lot of Harry Potter fanfiction, Albus Dumbledore is often considered one of the strongest wizards. His vast knowledge of magic, his strategic mind, and his powerful spells like his duel with Voldemort in the Ministry of Magic make him a top contender. Also, his leadership in the wizarding world against the dark forces is a testament to his strength.
Magical artifacts and connections can also play a part. A wizard who has a connection to a powerful magical artifact like the Elder Wand or the Resurrection Stone (as Harry did) can gain a significant boost in power. In fanfiction, a wizard might discover new and even more powerful artifacts that give them an edge, or they might have a special connection to a magical creature that gives them unique powers.
Powerful magic skills are a must. For instance, being able to perform extremely difficult spells effortlessly, like the Patronus charm in its most advanced form which can not only repel Dementors but also be used as a weapon against other dark creatures.
It could be that there has been some sort of misunderstanding. For example, Harry might have been wrongly associated with a dark magic item or a dangerous spell. And the Shield in the fanfiction, which could be some sort of secret or powerful organization, chases him to investigate or stop him from using this supposed 'evil' power.
It could be a rogue Death Eater who has been hiding and waiting for the right moment to strike at Harry. They might use some forbidden dark magic to seriously harm him.
Well, in a lot of Percy Jackson fanfiction, the primordial deities can be seen as the strongest beings. For example, Chaos, who is the very beginning of everything. It has the potential to create and destroy on an unimaginable scale. Since it is the origin of all existence in the Percy Jackson universe, it stands to reason that it would be extremely powerful. And there are also other primordial deities like Nyx, the goddess of the night, who has powers that are both mysterious and very potent. She can bring darkness and nightmares, and her powers are not to be underestimated in the fanfiction world.
One possible fanfiction could be where they are excited yet nervous about the pregnancy. Ginny might be worried about how her Quidditch career will be affected while Harry is concerned about protecting his family from any potential dark threats. They could start preparing a nursery at Grimmauld Place with help from Hermione and Ron, painting the walls with magical murals.
Harry Potter himself is often still a main character, but in a different light. Maybe as a sidekick or someone who is learning from the 'ultimate being'.
