Riven is often a common supporting character. He has a complex relationship with Musa, and in a dark Musa fanfiction, his role can be crucial in either helping her overcome the dark side or being influenced by her new, darker self. Another could be Stella. As Musa's friend, Stella might be there to try and bring back the old Musa, providing some light in her dark times.
One of the most common supporting characters would be Tecna. Given her logical mind, she could play a role in analyzing Musa's situation with the dark powers. Also, Flora might be present as she has a nurturing side. She could be trying to heal Musa or at least keep her from succumbing completely to the dark. And of course, Bloom might be there as the leader, trying to guide Musa through her dark phase.
Definitely Riven. His relationship with Musa is always a focal point. In a dark Musa story, he might be the one who is most affected by her change. Then there's Sky. He could be involved in the story as he has a connection to the Winx through Bloom. He might be trying to help the Winx deal with Musa's dark transformation, perhaps by providing resources or strategic advice. And Layla, who is also a friend of Musa, could be there to offer her unique perspective and support during Musa's dark journey.
Some common themes could be Musa's struggle with dark powers. Maybe she has to fight against the corruption of these powers within herself. Another theme might be her isolation as she deals with the dark side, as her friends may not understand what she's going through.
Another popular character could be Stella. Her powers related to light and sun could be in contrast to the dark fairy's powers. In fanfiction, Stella could be the one who uses her light - based magic to break through the dark spells cast by the dark fairy or to provide hope in a dark situation.
Typically, it's fans with a creative streak. They might be writers who are inspired by the Winx Club universe. These could be young adults or even teenagers who have grown up with the show and want to put their own spin on it. Some might be artists too, who use the concept of 'winx club dark winx fanfiction' as a basis for creating darker - themed art related to the Winx characters.
I really like 'Musa and Riven: A New Beginning'. In this fanfiction, they face a new threat together that forces them to rely on each other more than ever. It's full of action and also has some sweet moments between the two characters.
Obviously, Dark Flora is one of the main characters. She is likely to be central to the story with her unique powers and personality.
Baltor is a really intriguing Dark Fairy. His power and his complex relationship with the Winx Club make him a fascinating character. Another is the Trix. Their group dynamic and their unwavering commitment to the dark side are interesting. They often come up with devious plans that keep the story going.
In many fanfictions, Stella from Winx Club is a favorite. Her fashion - sense and her solar - based powers can make for some unique interactions with Pokemon. And of course, Pikachu is always popular in these crossovers. It's cute appearance and powerful electric attacks can be a fun addition to any story involving the Winx girls. It can be used as a sort of mascot - like character that brings a bit of light - heartedness to the crossover story.
The Trix also get a lot of attention. Since they are the main antagonists in the original Winx Club, in fanfiction they can be made even more menacing. Their backstories might be explored more deeply, like how they became so dark and what their ultimate goals are. They could be involved in a plot to take over the entire Magic Dimension in a more complex and devious way than in the show.
The character dynamics could be really interesting. Gantlos is often portrayed as a strong and somewhat rough character. Musa, on the other hand, is sensitive yet strong - willed, especially when it comes to her music. Gantlos might be initially dismissive of Musa's power in music, seeing it as a weak form of magic compared to his own combat - based abilities. But as he gets to know her better, he realizes the depth and importance of her music magic.
Well, perhaps in the fanfiction, Gantlos is on a mission that somehow involves Musa. He might be ordered to spy on her or steal something related to her music powers. But in the process, he starts to have feelings for her that he doesn't understand at first. Musa, on the other hand, senses that something is off about him but also can't help being intrigued. Their relationship could develop from a cat - and - mouse game to a more romantic one.
