Harry Potter himself could be involved. Maybe he accidentally consumes a modified version of the Draught of Living Death and his friends have to find a way to wake him up. This would put them in a race against time and force them to explore the darker corners of potions - making in the wizarding world.
Severus Snape is also a common character. As the Potions master, he has a deep understanding of the Draught of Living Death. Fanfictions may show him teaching students about it, or perhaps using it in some secret plot related to his double - agent role. He could be the one to discover a new property of the potion.
Obviously, Harry Potter himself is always a main character. He is the one most directly associated with the concept of death in the original series, what with his parents' death and his multiple near - death experiences.
In some fanfictions, the Draught of Living Death might be used in a different context, like in a magical duel. For example, a wizard could use it to immobilize their opponent instead of for sleep. It adds a new layer of strategy to the wizarding battles. Also, it could be that a character tries to reverse the effects of the potion in an unorthodox way, leading to unexpected magical consequences.
In many 'Harry Potter God of Death Fanfiction', Albus Dumbledore can be a significant character. Given his vast knowledge and power in the original series, he might have some prior knowledge or connection to the God of Death. His wisdom could be used to guide the younger characters in dealing with this new and dangerous entity. Additionally, characters like Severus Snape could also be involved. His complex nature and his own experiences with death could make him an interesting addition to the story when it comes to interacting with the God of Death.
Harry Potter himself is often involved. Since he is the central character in the original series, fanfiction writers like to explore what would happen to him in a death and reset scenario. For example, if he died and was reset, how would his journey to defeat Voldemort change? Would he have different powers or knowledge?
Definitely Harry Potter. His death or his experiences after death can open up a lot of storylines. Sirius Black might be a popular character in such fanfictions too. He died quite tragically in the original story, and his return in some form in the afterlife could be really interesting. Luna Lovegood could also be involved. Her unique perspective on life and magic might translate into an interesting role in the afterlife. And Severus Snape, considering his complex character and his ultimate sacrifice, he would be a great addition to explore in the afterlife scenarios.
Hermione is often involved. Since she's Harry's best friend, she might be the one trying to prevent his death in some fanfictions. Or she could be the one who has to carry on his legacy after he dies.
Ron Weasley could be another main character. He might be by Harry's side, providing the loyalty and friendship he always has. In some fanfictions, he could also gain some unique abilities or knowledge related to Harry's new state. And Dumbledore, even in death, might still have an influence. His past knowledge and wisdom could be a guiding force for Harry as he navigates his new immortality and power as the Master of Death.
Another character could be Draco Malfoy. There could be fanfiction where Draco, having been on the wrong side for a long time, now has a change of heart and wants vengeance against his own family or the Death Eaters who used him. He might use his knowledge of the Dark Arts that he learned from his family, but now turn it against them in a bid for redemption through vengeance.
Harry Potter himself could be one of the main characters in such fanfiction. Maybe he gets an automail limb after a particularly dangerous encounter with Voldemort. Hermione might also be involved, using her vast knowledge to help understand and improve the automail technology within the wizarding context.
Harry Potter himself is often a central character. Since he was the one destined to defeat Voldemort and destroy the Horcruxes in the original story, many fanfictions continue his journey with Horcruxes in new and different ways. Hermione Granger also features prominently. Her intelligence would be crucial in understanding the nature of Horcruxes and finding ways to deal with them.
