Sirius Black is an excellent choice. His rebellious nature and his connection to Harry can bring in some interesting storylines. He could be like a mentor to the triad, especially when it comes to dealing with the darker aspects of the wizarding world. Neville Longbottom can also be included. He has his own growth arc in the original series, and in a triad fanfiction, he could be a source of support and strength, especially when they are all facing challenges in Hogwarts.
One characteristic is the presence of multiple love interests. In triad romance novels, there are usually three main characters involved in some sort of romantic entanglement. Another is the emotional conflict. The characters often struggle with their feelings for more than one person, leading to a lot of internal and external drama. For example, in a story, a character might be in love with someone who is their best friend's partner, creating a tense situation.
A 'triad novel' could be a novel that involves the concept of a triad. It might be about the relationships, power dynamics, or stories within a triad structure. For example, it could focus on three main characters and their interconnections, like a love triangle where three people are involved in complex emotional relationships. It could also be related to the idea of three elements in a story, such as three different plotlines that converge or three different settings that play important roles in the narrative.
I'm not sure of specific 'triad novels' off the top of my head. But you could look for novels that have three main characters with a strong focus on their relationships. For example, 'The Hunger Games' has Katniss, Peeta, and Gale which could be seen as a sort of triad in the story.
One popular triad romance novel is 'The Vampire Diaries' series. It involves a complex love triangle among the main characters. Another could be 'Twilight', which also has elements of a triangular romance. And 'Pride and Prejudice' can be seen as having a sort of triad romance in a way, with Elizabeth, Darcy, and Wickham.
Obviously, the Shadow Triad themselves are the main characters. They are a group of mysterious and powerful figures in the Pokemon world. Depending on the plot, other characters like the main Pokemon trainer from the games or anime could also be important. Maybe a Gym Leader who gets involved with the Shadow Triad's activities.
In gay triad romance novels, a frequent theme is the power dynamics within the triad. Each person may bring different strengths and insecurities, and the novels often explore how they balance power and decision - making. Another common theme is jealousy. Since there are three people involved, jealousy can be a complex emotion to navigate. And of course, the theme of unity is also important. The three characters need to figure out how to be united in their relationship, whether it's facing external challenges or just growing together as a unit. This unity is often what makes the relationship in these novels strong and endearing.
The main characters are Hermione, and the Weasley twins, Fred and George. Hermione is known for her intelligence and academic prowess. She is often the voice of reason among the group.
One idea could be exploring the backstories of the Shadow Triad members. Maybe they were once ordinary trainers who were forced into their current role. Another idea is to have them encounter a powerful, new Pokemon that challenges their loyalty to their master. Or perhaps a fanfic where they have to team up with the main Pokemon protagonist to face a common enemy.
