A really cool fanfiction is the one that focuses on how the sorcerer staff is the key to an ancient magic that can save the wizarding world from a new, unknown threat. Harry, with the help of his friends, has to unlock the secrets of the staff in order to succeed.
A fanfiction called 'Potter's Ascendance' is also worth reading. In it, Harry starts to show signs of being an extremely powerful sorcerer from a young age. The story follows his journey as he rises above the challenges in Hogwarts and the wizarding world, using his extraordinary powers not just for himself but for the greater good of the wizarding community. It has a great character development arc for Harry.
Some fanfictions have the idea that the sorcerer staff can transform into different forms depending on Harry's needs. For example, it can turn into a sword when he's in combat or a key to unlock hidden magical chambers.
Neville Longbottom could also be a worthy wielder. He has shown great courage and growth throughout the series. With the Grand Sorcerer Staff, he could rise to be a powerful force in the wizarding world, using the staff's power to stand up against any remaining Death Eaters or new dark threats, and also to bring new life and growth to the Hogwarts herbology department which he loves.
One idea could be that the Grand Sorcerer Staff has a mind of its own and it chooses a young, unexpected wizard to be its new master. This wizard then has to learn how to control the powerful magic within the staff while also facing the challenges from dark wizards who want to steal it.
One popular fanfiction idea could be Harry Potter unlocking a hidden ancient magic that makes him even more powerful than in the original series. He could use this power to quickly defeat Voldemort and then go on to reshape the wizarding world, for example, by introducing new spells and magical teachings.
The staff could make him more confident. If it has powerful magic, he would feel more capable of taking on difficult tasks. So, his character might shift from being a bit hesitant to more assertive.
I think it has the potential to be good. It combines two very cool concepts - Harry Potter and the Sorcerer Supreme. However, the quality can vary a lot. Some fanfiction writers do an amazing job of weaving a new story within the existing Potterverse, while others might not be as skilled.
Well, there are fanfictions that focus on Harry as a super - powerful sorcerer from the very start. Instead of gradually learning magic at Hogwarts, he already has a vast knowledge and can perform advanced spells. Also, there are those that revolve around Harry's love life in a more complex way, such as having a love triangle with Hermione and Ginny, but with a whole new set of magical challenges and adventures thrown in.
It could be Dumbledore. Dumbledore is always full of surprises and he might give Harry the staff as a last - resort weapon to fight against Voldemort. He could have been secretly researching the staff and its powers and decided that Harry was the only one who could wield it properly.
It could be an ancient relic passed down from a long - lost wizarding clan. Maybe it was hidden away for centuries until Harry discovers it by chance.
