A common plot is that Malfoy spreads false rumors about Harry in the wizarding world. This causes problems for Harry, like making some students avoid him or look at him with suspicion. When Harry finds out that Malfoy is the source of these rumors, he gets angry and beats him up. There are also fanfictions where Malfoy tries to get Harry expelled from Hogwarts by framing him for something he didn't do. Harry, being the brave character he is, doesn't take this lying down and gives Malfoy a good thrashing.
A common plot is Draco going back in time to fix his mistakes. For example, in many fanfictions, he tries to avoid getting involved with the Death Eaters in the past, knowing the consequences it will bring in the future. This often leads to him having to interact with a younger Harry Potter in new ways.
It can make Harry seem more hot - tempered. Instead of always being the patient hero, beating up Malfoy shows his impulsive side. He's not just the boy who waits for the right moment to fight Voldemort, but someone who can take immediate action when his friends or his own pride is at stake.
One popular plot could be that Batman discovers Superman has been mind - controlled by some villain. So, in order to save Superman and the world, Batman has to fight him. Another plot might involve a misunderstanding. Maybe some false information leads Batman to believe Superman is a threat to Gotham, and he takes action. There could also be a plot where Batman is pushed to his limits by some external force that makes him see Superman as an obstacle, and he uses his wits and skills to take on the Man of Steel.
Well, in some fanfics, like 'The Darker Side of Redemption', Lucius is given a chance at redemption after the fall of Voldemort. Harry plays a key role in this process, either by being a reluctant helper or an unexpected friend. The plot often involves exploring the darker parts of the wizarding world that were not fully shown in the original books.
Well, a common plot involves the characters swapping places. Luffy ending up in Hogwarts and having to deal with magic lessons while Harry finds himself on the Thousand Sunny. Also, there are plots where they team up to solve a common threat that endangers both their worlds, like a new dark magic that spreads to the One Piece world.
One common trope is the 'Forced Partnership' due to a creature. Like when a dangerous magical creature threatens Hogwarts, and Harry and Draco have to team up. It creates a lot of tension and opportunity for character development. They start off hating each other but as they face the creature, they learn more about each other.
One popular plot is the redemption of werewolves. In these fanfictions, Harry Potter or other characters use their control methods to help werewolves integrate into wizarding society. For example, they might find a way to control the werewolf transformation so that werewolves can lead normal lives and not be shunned.
Perhaps a plot where Harry, as the son of Malfoy, discovers a hidden prophecy that links him to the downfall of Voldemort in a completely different way than in the original series. This could involve him using his knowledge of the Malfoy family secrets and connections to gain an advantage over the Dark Lord.
One possible plotline could be that Harry discovers a new dark plot by pureblood supremacists to further marginalize non - pureblood wizards. He decides to take matters into his own hands and uses his magic to fight them off. Another could be that he is pushed to the limit by the constant discrimination from purebloods and finally snaps, leading to a showdown.
Yes, there might be some out there. However, it's important to note that the 'beating up' aspect should be in line with the overall themes of justice and equality in the Harry Potter universe. Some fanfictions might handle this concept well, showing Harry standing up against the unjust pureblood supremacy ideology in a way that stays true to his character.
