One idea could be to explore a modern - day AU (Alternate Universe) where the Swan Queen characters are in a rock band, and 'Paint it Black' is their signature song. They could face challenges in the music industry while also dealing with their complex relationship.
In a fanfiction, the Black Knight Queen could be a time - traveler. She comes from a future where the world is in chaos and she believes that by changing the past (the time of the Totally Spies), she can prevent the apocalypse. This would lead to a lot of interesting interactions as the Totally Spies try to figure out if she's a friend or foe.
One possible fanfiction could be about the Black Knight Queen's origin story. Maybe she was once a regular person who was wronged by a powerful organization and decided to take on the persona of the Black Knight Queen to seek revenge. She could have special powers or skills that she uses to outwit the Totally Spies.
One interesting story could be about the Black Queen's rise to power. Maybe she starts from a humble beginning and through her wits and determination, she overcomes various challenges and rivals. Another could be a love story where the Black Queen falls in love with an unexpected character, which changes her perspective on things. And there might be a story where she teams up with other powerful characters to fight a common enemy, showing her ability to form alliances.
I'm not sure specifically as there could be many different interpretations in fanfiction. It might be about a female character who is seen as the 'Black Queen' in the context of the Harry Potter universe. Maybe she has dark magic powers or is involved in some sort of power struggle within the wizarding world.
In some Black Queen fanfiction, the Prince of Shadows is frequently paired with her. Their relationship can be complex, perhaps they are rivals at first but then find common ground. There's also the Enchantress. Since both are female characters with great power, their interactions can range from intense competition to unexpected alliances. And don't forget the Lone Wanderer, who might be drawn into the Black Queen's orbit and become an important part of her story.
One common theme is time - travel. Since there's a 'Time Queen' involved, the stories often play with the idea of Sirius Black traveling through time, either to change the past or to understand the future. Another theme is the power struggle. The Time Queen usually has some sort of powerful abilities related to time, and Sirius might be caught up in a struggle for power or against those who misuse the time - related powers.
Since I haven't read this particular fanfiction, it's hard to say for sure. But it's likely to be the Black Queen herself. She would probably be the central figure around which the story revolves.
An ancient and malevolent spirit that was once trapped in the black puddle but has now been freed could be a major antagonist. This spirit wants to take over the queen's body and use her connection to the puddle to spread chaos across all the realms. It constantly whispers dark thoughts into the queen's mind, trying to make her lose control and become a puppet for its own evil plans.
The Tushan Black Fox Queen was a monster from ancient Chinese myths and legends. It came from the Qing Dynasty novel, Strange Tales from a Chinese Studio. She was the leader of the Tushan fox race. She had great power and intelligence, and could transform into a human. Mud Mountain Black Fox Queen was usually portrayed as a beautiful, intelligent, and cunning woman. She fell in love with human men and helped them solve all kinds of problems. In some legends, the Mud Mountain Black Fox Queen was also described as an evil monster. She would use her beauty and power to seduce human men and harm them.
