One great fanfiction could be 'The Slytherin Journey of Albus Severus Potter'. In this fic, it delves deep into his struggle to fit in Slytherin while carrying the Potter name. It shows how he overcomes the initial prejudice from his housemates and becomes a respected figure in Slytherin.
Another theme is redemption. In some fanfics, Slytherin has a bit of a bad reputation. Albus tries to redeem the name of Slytherin by his actions and choices. For example, he might work towards breaking the stereotype that all Slytherins are evil or self - serving.
His father, Harry, would probably be initially shocked. But he would also be understanding and supportive. After all, he knew that Slytherin wasn't all bad. His mother, Ginny, might worry a bit more, especially about the potential for Albus to be influenced by some of the more traditional Slytherin values. However, she would also encourage him to be true to himself.
Well, a plot could revolve around Albus making unexpected friends in Slytherin. He might find those who are also outsiders in a way, like a half - blood who is looked down upon by the pure - blood elitists in the house. Together, they could work on changing the perception of Slytherin from within. Also, there could be a mystery in the Slytherin common room that Albus is determined to solve. It could be related to a former Slytherin's dark secret that has been plaguing the house for generations.
A fanfic that stands out is 'Albus Severus Potter: The Time - Turner Quest'. It's about Albus finding a time - turner and going on a journey through time to understand the past of Hogwarts and his family. It's a really creative take on his character. 'Albus Severus and the Cursed Vaults' is another good one. It has elements similar to the 'Cursed Vaults' storyline in the 'Hogwarts Mystery' game but focuses on Albus's adventures. And 'Albus Severus Potter: The House Unity' shows how Albus tries to bring unity among the different houses at Hogwarts, which is a really positive and interesting concept.
One common theme is the struggle with identity. Given his famous family name, Albus Severus often has to find his own place in the wizarding world. For example, in some fanfics, he tries to break free from the expectations set by his father.
Most likely, his parents, Harry and Ginny Potter, could send the howler. They would be concerned about their son's well - being and actions at Hogwarts. If Albus got into trouble or was not living up to the Potter family name, they would not hesitate to send a howler to set him straight.
There are definitely some great ones. For example, some fanfictions focus on Albus Potter's relationships with his Slytherin housemates. They might show how he forms unexpected alliances and how his Slytherin traits, like cunning and ambition, are developed in different ways compared to what one might expect from a Potter. These fanfictions often provide a fresh perspective on the Harry Potter universe.
There could be a fanfiction where Albus Severus Potter gets transported back in time to the era of his father's youth. He could witness the events that Harry went through first - hand, but also accidentally change some small things that have big consequences for the present time. He then has to find a way to fix the timeline without completely erasing his own existence.
