A possible plotline is that the Hex Girls accidentally cross over into the Naruto world during a powerful magical event. They find themselves in the middle of a war between two ninja villages. Naruto, seeing that they are not from there and are in danger, takes them under his wing. The Hex Girls then use their unique abilities to help Naruto and his village defend against the enemy. In the process, they learn about the ninja way and Naruto and his friends learn about the power of music and magic from the Hex Girls.
It could be a really interesting crossover. Maybe the Hex Girls are on a mission in the Naruto world and they use their unique musical powers to fight off some of the villains there. Their goth - style would be quite a contrast to the ninja world.
One possible fanfiction could be about Scooby Doo and the gang encountering the Hex Girls during a music festival in a spooky forest. The Hex Girls' music has some strange effects on the forest creatures, and Scooby and Shaggy are both scared and intrigued. They have to work together to figure out if there's something truly supernatural going on or if it's just a really cool music trick.
Well, in a fanfiction, the Hex Girls might be trying to unlock an ancient musical power. They believe it's hidden in an old, abandoned theater. Scooby Doo and his friends join them on this quest. However, the theater is full of traps and ghosts. As they explore, they learn that the ghosts are actually the guardians of the power. The Hex Girls must prove their worthiness through their music, and with Scooby Doo's help in distracting the ghosts, they are able to unlock the power and become even more amazing musicians.
Well, it combines two very different elements from the Scooby - Doo universe. Shaggy is the laid - back, food - loving character, while the Hex Girls are this cool, goth - punk band. The unique part is seeing how their personalities interact. Maybe Shaggy is drawn to their edgy style, or the Hex Girls find his simplicity charming.
There are some out there. You can start by looking on fanfiction websites. Some might be hidden among a lot of other content, but if you search specifically for 'Shaggy x Hex Girls', you might find some interesting reads.
Well, in some Harry Potter hex fanfiction, there are hexes related to time manipulation. This is really exciting as it adds a whole new dimension to the wizarding world. Imagine a hex that can slow down time in a small area, like a classroom during an exam, so the caster has more time to answer questions. It's a very cool concept that can lead to all sorts of interesting plot developments.
Obviously, the hex maniac herself is a central character. There could also be a young and inexperienced trainer who looks up to the hex maniac for her knowledge of the more mysterious aspects of the Pokemon world. Another character could be an old and wise Pokemon professor who has some knowledge about hexes but not as much as the hex maniac.
Draco Malfoy is frequently included as well. His family's dark arts tendencies make him a likely candidate to be involved with hexes, either using them for his own gain or getting caught up in a plot where he has to deal with the consequences of using or being affected by a hex.
