A common plot in such fanfictions is the idea that death has a plan for Harry that goes beyond what Dumbledore or anyone else expected. It could be that death wants to use Harry to balance the magical world in a different way. So, Harry might be led to discover ancient magic that is related to life and death, and he has to decide how to use it. This could involve making alliances with creatures that are associated with death, like thestrals or dementors in a different context.
One interesting plot could be the different ways characters' deaths impact the wizarding world's power balance. For example, if a key member of the Order of the Phoenix died, it might lead to a shift in the fight against Voldemort.
One interesting plot could be that Harry Potter, as the Master of Death, encounters Aphrodite in the wizarding world. Maybe Aphrodite is intrigued by the concept of death in the wizarding realm and wants to learn more. Harry, in turn, is fascinated by her powers of love and beauty. They could team up to help a young wizard who has lost all hope and love due to a dark magic curse, with Aphrodite using her love - inducing powers and Harry using his mastery over death to free the wizard from the curse's hold on his soul.
A possible plot could also be Harry's relationship with his friends in this new context. They might be initially scared or confused by his new identity. However, through their friendship, they come to accept and support him. Hermione could use her vast knowledge to help Harry understand his powers better, while Ron could provide the emotional support and loyalty that he always has.
One interesting plot could be a group of young wizards and witches forming an underground resistance against the Death Eaters. They might use unique spells and magical artifacts that are not well - known in the original series to outwit the Death Eaters.

And a third plot might involve time - traveling within the Potter family's history to correct past mistakes or learn from them.
In some 'Death Ace' Harry Potter fanfictions, 'Death Ace' might be a new villain. This character could be creating chaos in the wizarding world in a different way than Voldemort did. For example, instead of focusing on pure - blood supremacy, they might be after a powerful magical artifact that could change the balance of power in the wizarding world. Their actions would then force Harry and his friends to face new challenges and use different strategies to stop them.
One interesting plot could be the Marauders' adventures during their school days that were not fully explored in the original books.
