Maybe in this fanfiction, Harry has a hidden power within him that is only revealed later. It could be something related to his family heritage that Dumbledore doesn't possess. Also, the author might have decided to give Harry more power to explore different storylines. For instance, Harry could be more powerful because he has a stronger bond with the magical creatures, which gives him additional powers that Dumbledore lacks.
In this fanfiction, it could be that Harry's power stems from his experiences. He has faced numerous dark wizards and challenges, which have forced him to grow stronger. Merlin, on the other hand, might not have had such intense and varied experiences. So, through his trials, Harry has developed powers that surpass Merlin's.
It completely flips the power structure. Normally, Dumbledore is seen as one of the most powerful wizards in the original series. But in this fanfiction, Harry being more powerful means that the traditional hierarchy is disrupted. For example, battles and challenges that Dumbledore would usually handle might now be Harry's domain.
One reason could be his pure heart. Harry's pure intentions and lack of desire for power for power's sake gives him an edge. His magic is not corrupted like Voldemort's. It flows more freely and is more in tune with the natural order of magic. So, when he casts spells, they are more effective.
Well, in some fanfictions, Harry Potter might be seen as more powerful than Merlin because Harry has faced and defeated Voldemort. That's a huge accomplishment. Merlin, while very powerful in his own right, didn't have to deal with a dark wizard as complex and powerful as Voldemort. Harry's ability to survive the Killing Curse as a baby also gives him a sort of 'chosen one' status that could be seen as making him more powerful.
Magic knowledge. Harry has a lot of knowledge from Hogwarts, which could be more comprehensive than what Merlin had. So in fanfiction, this knowledge could be used to show he's more powerful.
It's really hard to say. Dumbledore is known for his vast magical knowledge and powerful spells. However, Lily Potter was also a very talented witch. If we consider her love - based magic, like the protection she cast on Harry, it could be extremely powerful. In a direct magical duel, Dumbledore might have the upper hand in terms of experience and a wider range of spells, but Lily's love - fueled magic could be unpredictable and potentially very strong.
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.
Well, in some fanfictions, Loki is often depicted as more powerful than Thanos because of his magical abilities. Loki is a master of illusion and deception. He can create complex illusions to mislead his opponents, including Thanos. Thanos, on the other hand, mainly relies on his brute strength and the Infinity Stones. But Loki's magic can sometimes outwit Thanos' straightforward power plays.
In the world of online literature, there were many characters that were set to be even stronger than Sakra. Among them, the more well-known ones included:
1. [Heavenly Dao: Heavenly Dao is the highest rule of the world set in some web novels. It is the controller of the world and is even stronger than Sakra.]
2. Pangu: Pangu was the God of Creation in ancient Chinese myths and legends. He appeared earlier than Sakra and was considered one of the most powerful existences.
3. Primordial Chaos: Primordial Chaos was the primordial qi of chaos in Taoist mythology. It was the source of all things in the universe and was considered to be an existence more powerful than Sakra.
These characters might have different abilities and settings in different novels, so it was impossible to simply compare who was stronger.
