People might consider Harry Potter as a Pendragon fanfiction due to the similarities in the moral and ethical themes. Both stories often deal with good versus evil, the importance of friendship and courage. Also, the way the hero in each story has to learn and adapt to new situations. Harry has to learn new spells and about the wizarding world, similar to how the hero in Pendragon has to learn about the different worlds and their rules. This resemblance in the overarching themes could be a reason for the thought.
Some people might think this because of the common theme of a young hero on a journey. In both, there is a central character who has to face great challenges and grow throughout the story. Also, the use of magic or some form of special powers is present in both. In Pendragon, there are powers related to the different worlds and in Harry Potter, there are spells and magical abilities. This similarity in the basic structure of the story could lead to such a thought.
Well, it could be the idea of a parallel universe or different realms which is somewhat common in both. In Pendragon, there are multiple worlds and in Harry Potter, there is the wizarding world and the Muggle world. The concept of a character being 'chosen' or having a special destiny is also there in both. Harry is the 'Chosen One' and in Pendragon, the main character also has a special role to play. These shared concepts might make people think Harry Potter has elements of Pendragon fanfiction.
