Ryan could be more adventurous than Harry. Maybe he's always the one to take risks first, dragging Harry along on his escapades. This trait could lead him to explore areas of the wizarding world that are off - limits or dangerous, which in a WBWL scenario could have major consequences for the story.
Ryan could also be more empathetic. In a world full of fear and chaos after Voldemort's victory, his empathy could make him a beacon of hope for those who are suffering. He might be the one to reach out to the downtrodden and form a resistance based on compassion and unity, which would be a different approach compared to a more combat - based resistance that Harry might lead.
He might be more of a thinker. While Harry is often impulsive in his actions, Ryan could be the one who sits back and strategizes. In a world where Voldemort has won, this could be crucial. He could be planning ways to undermine Voldemort's regime from the shadows, using his intelligence and knowledge of magic to outwit the Dark Lord and his followers.
Ryan might change the story by being more attuned to the Dark Arts in a different way than Harry. Since Harry has always had an aversion to the Dark Arts, Ryan could potentially explore and understand them in a way that gives him an edge. He could use this knowledge either to side with Voldemort (if he's a morally grey character) or to find a weakness in Voldemort's use of the Dark Arts to defeat him. In a WBWL scenario, this could be a huge turning point.
Their relationship could start off rocky as they are strangers at first. But as they discover their shared past and experiences, they might become closer. They could support each other through the challenges of the wizarding world, like dealing with bullies at Hogwarts or facing dark wizards.
One possible plot twist could be that Ryan was thought to be dead but actually was hidden away by some powerful magic. This could lead to a situation where he suddenly reappears and has to adjust to the wizarding world while also dealing with his new - found relationship with Harry. Another twist could be that Ryan has different magical abilities compared to Harry, which causes envy or admiration among the wizarding community.
He could be very brave. Just like Harry, but perhaps in a more understated way. He might not be the 'chosen one' but still jumps into danger to protect his brother.
One great WBWL fanfiction is 'The Black Prince'. It offers a unique take on Harry having a twin and how it would change the story. The plot development is really engaging as it shows how the twin's presence affects the relationships with other characters like the Weasleys and Hermione. It also delves deep into the wizarding world politics in a way that feels fresh.
Lemon could be brave like Harry. Since they are twins, she might inherit the same Gryffindor - like courage. She could be the type who doesn't shy away from standing up to bullies at Hogwarts, just like Harry does with Draco Malfoy.
Often, the mates can have diverse traits. For example, a mate could be highly empathetic, being able to sense others' emotions. Another might be a bit of a rebel, challenging the norms of the wizarding world. And there could be a mate who is extremely resourceful, finding solutions in the most difficult situations. The fourth could be the calm and collected one, providing stability to the group. These traits help them support Harry in different ways and create interesting storylines within the fanfiction.
She would likely be very charming. Aphrodite is the goddess of love and beauty, so her daughter would inherit that allure. She might be able to easily win people over with just a smile or a kind word. Also, she could be quite passionate, given Aphrodite's connection to strong emotions like love.
She could be shy and reserved, in contrast to Sakura's more assertive nature. This shyness might make her seem mysterious at first.
One common theme is the struggle between the human side of Ryan Potter's character and the allure of the vampire world. Another is the forbidden love aspect, as in many vampire stories. It could be a love story between Ryan Potter's character and a vampire.
