What are the possible reasons for Harry having more than one Patronus in fanfiction?

Yes, in many fanfictions, Harry is often depicted as having more than one Patronus. Fanfiction writers like to explore different aspects of magic and character development, and giving Harry an additional Patronus can be a creative way to do this.

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.

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.

Fanfiction usually stays within the fan community and doesn't directly affect Harry's story in the official books. So he has no reason to fight it.

In fanfiction, there are numerous interpretations for Harry having scars on his back. It could be a symbol of his past traumas. For example, he could have been bullied at Hogwarts in a more extreme way that left physical scars. Or it could be related to his family history. Maybe there was some dark family secret that involved a ritual which scarred his back. Additionally, it could be from a forbidden magic he tried to learn in order to defeat Voldemort once and for all, and the magic had unforeseen consequences on his body.

A possible reason could be for self - expression. Naruto is a very expressive character, and tattoos could be another way for him to show who he is. It could also be a way to distinguish himself from other ninjas.

Well, perhaps in this fanfiction, Harry's different Patronus could be something unexpected like a phoenix. It might signify a new aspect of his character, such as a stronger connection to the magical world's renewal and rebirth. Maybe this different Patronus is a result of an alternate event in his life, like a different encounter with a powerful magical being that changed the form his Patronus takes.

One reason could be that Harry is under an extreme amount of stress. He has so many burdens on his shoulders in the wizarding world, like fighting Voldemort. This stress could manifest physically as a seizure, especially if he is in a tense situation in front of Snape, who is often a source of anxiety for him. For example, if Snape is about to accuse him of something he didn't do while he is already worried about other threats to the wizarding world.

Yes, having multiple friends is wonderful. Each friend has their own unique personality and interests. Some friends might be there for you when you need emotional support, while others are great for going on adventures. With more than one friend, your social life becomes more diverse and exciting.

A storyline might involve a character who discovers their Thestral Patronus during a time of great personal loss. They then embark on a journey to understand the significance of it. Along the way, they meet other characters with unique Patronuses and together they form a sort of 'Patronus alliance' to fight against a new threat in the wizarding world that is related to the darker aspects of magic which the Thestral Patronus represents.
