Well, I really liked 'The Time - Albus Severus Adventure'. It has Albus Severus accidentally traveling to a time when Hogwarts was just being built. He has to figure out how to get back while also learning a lot about the origins of magic in Hogwarts. It's a really cool concept and the author does a great job of describing the ancient Hogwarts. There are also some really neat time - travel paradoxes explored in it.
One idea could be Albus Severus Potter traveling back in time to meet his father, Harry Potter, as a young student at Hogwarts. He could then help his father in some of the early battles against Voldemort, using the knowledge he has from the future. This would create a lot of interesting interactions and changes to the original story line.
One possible antagonist could be a dark wizard from the past who somehow catches wind of Albus Severus' time - traveling and decides to use his knowledge of the future for his own evil purposes. Maybe a forgotten Death Eater who was thought to be dead but actually survived in hiding and now sees this as an opportunity to rise again.
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 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.
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.
In some Albus Severus time travel fanfiction, the plot involves him going back to the time of the founders of Hogwarts. This is fascinating because he gets to interact with the likes of Godric Gryffindor and Salazar Slytherin. He might have to choose sides in an old conflict or even try to prevent the split between the houses. It's a really cool concept that explores the roots of Hogwarts and the wizarding world. Also, there are plots where he travels to a time when dark magic was on the rise and he has to fight against it using his knowledge from the future.
There's a fanfiction titled 'Harry Potter: Albus's Destiny'. It focuses on how Albus Severus Potter discovers his own unique path in the wizarding world, different from his father's. It's a great read as it shows his struggles and how he overcomes them.
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.
