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.
Well, there's 'The Unlikely Mentorship'. In this fanfic, Snape, in a sort of after - life state, starts to guide Albus Severus. It's really interesting as it shows Snape's softer side towards the young Potter. And 'Albus Severus and the Memory of Snape' is also quite good. It focuses on Albus Severus finding an old memory of Snape that changes his perspective on a lot of things.
Snape's reaction would be complex. He has so much history with the Potter family. At the start, he might show his usual cold exterior. However, if Albus shows respect and a genuine desire to learn from him, Snape could gradually warm up. He might share some of his potions knowledge and secrets that he never shared with others. He may also tell Albus stories about his mother, Lily, in a roundabout way, to help Albus understand his family's past better and the sacrifices that were made for him to be alive.
Yes, there are quite a few. You can find them on popular fanfiction websites like Fanfiction.net or Archive of Our Own. Some focus on his relationships within the wizarding world, often exploring romances with original characters or even with characters from the main series in new and interesting ways.
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.
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.
I really like 'Albus Severus and the Lost Magic'. In this fanfic, Albus discovers an ancient form of magic that has been long forgotten. It's a really exciting read as he tries to master this new magic while also dealing with the regular Hogwarts drama. The way it ties in with the existing Harry Potter lore is quite clever.
There are many interesting fanfictions on this topic. Some might explore how Albus discovers his Parseltongue ability. Maybe it could be a hidden talent that surfaces during a dangerous situation at Hogwarts, like when he stumbles upon a hidden chamber with a snake - related mystery.
In fanfiction, Albus Severus Potter often embarks on various adventures. When it comes to the mention of 'lemon' in relation to him, it might refer to a type of trope in fanfiction where there could be some light - hearted or slightly comical situations. For example, he might encounter a magical lemon that has some special powers. However, it could also be misinterpreted as something inappropriate if not used in a proper context.
