It could lead to all sorts of interesting plot twists. Maybe there's competition or a stronger bond between them.
Well, when Draco has a twin brother, it might change his character development and his relationships within the story. There could be conflicts or shared adventures.
Well, they could have a very complex relationship. On one hand, they might be extremely competitive, always trying to outdo each other in everything from academics to impressing their parents. Since they are in Slytherin, they could also team up and be a formidable duo, using their combined wits to get what they want in the wizarding world. Maybe they have a secret pact to protect each other no matter what.
The twin could change a lot. He might be the one who stops Draco from making some really bad decisions. For instance, if Draco was about to follow Voldemort's orders blindly, the twin could convince him otherwise. This would then change the whole course of Draco's actions and how he interacts with Harry Potter and his friends.
Maybe the story is about their rivalry. Sol is jealous of Draco's popularity among their Slytherin peers. He tries to outdo Draco in everything, from academics to Quidditch. This causes a rift between them. However, when Draco gets seriously injured in a Quidditch match, Sol realizes how much he actually cares about his brother. He then helps Draco recover and they reconcile, vowing to support each other instead of competing all the time.
Maybe the twin brother has a special power that Draco doesn't. For example, he could be a seer like Trelawney but more accurate. His visions could show him the future of Hogwarts and the wizarding world during the dark times of Voldemort's return. He then tries to use this power to prevent bad things from happening, but Draco is suspicious of his actions and tries to stop him, thinking he's going against their family and the Dark Lord.
They might have a really close, protective relationship. His brother could be the one who always has Draco's back. Like when Draco gets into trouble with other students or is under pressure from the Death Eaters, his brother steps in to help him out, even if it means going against the family's traditional views sometimes.
Well, it could lead to all sorts of adventures and interactions. Maybe they form an unlikely friendship or have a rivalry from the start.
At first, it could be strained. Draco, being used to being the only son in the family's eyes, might feel threatened by his twin. He could be jealous if his twin shows more magical talent or is more popular at Hogwarts. But as they grow older, they might start to understand each other better. For example, if they face a common enemy, like a bully from another house, they could come together and realize the importance of family.
One common theme is the exploration of family bonds. Since they are twins, the fanfictions often delve into how their relationship is different from normal siblings. Another theme could be competition. They might compete with each other in Pokemon battles or in achieving certain goals in the Pokemon world.
It could lead to all sorts of drama and conflicts. Maybe Draco is embarrassed or gets angry and retaliates.
Often, when Draco gets a howler from Annabeth in fanfiction, it creates tension and conflict. It might expose something secret or force them to confront their feelings. Also, it could draw in other characters and complicate the story even more.
