Another important aspect is character development. Even though it's a 'Bad Vlad' fanfiction, you can still show some layers to his character. Maybe he has a moment of self - doubt or a soft spot for a certain character. This will make the story more interesting and complex. Also, make sure to have a good flow to the story, with a clear beginning, middle, and end.
First, know the characters well. Read up on their personalities, backstories, and relationships in the original show. For Vlad, his pride and his complex feelings towards Maddie are key. Maddie is smart, brave, and dedicated to her family. Then, come up with a unique plot. It could be a conflict that forces them to interact in a new way, like a new ghost threat that only they can solve together.
For Danny, focus on his youth and inexperience as a half - ghost. Show his sense of justice and his struggle to balance his normal life with his ghost - fighting duties. For Vlad, emphasize his complex personality. He's a villain but also has a tragic backstory. Write about his jealousy of Jack and his longing for a family. Use their interactions to highlight their differences and similarities.
There might be a fanfiction where 'Bad Vlad' teams up with other villains from the Danny Phantom universe. For example, he could form an alliance with some of the more powerful and evil ghosts to finally defeat Danny and rule both the human and ghost worlds. In this type of fanfiction, the story would focus on Danny's struggle to break up this alliance and save his town and the ghost zone.
I'm not very familiar with this specific 'danny phantom abusive vlad fanfiction'. But generally, in fanfiction, an 'abusive' aspect might involve one character treating another in a negative, often unethical or harmful way. In the context of Danny Phantom and Vlad, it could be about power dynamics, with Vlad perhaps using his abilities or position to mistreat Danny in the fictional story.
One aspect of Danny Phantom x Vlad fanfiction could be the exploration of their complex relationship. In the original series, they are adversaries with a lot of underlying tension. Fanfictions might focus on what would happen if they were forced to work together, perhaps in a situation where a greater threat emerges that requires both their powers. This could lead to interesting character developments as they learn more about each other.
In some fanfictions, memory loss for Danny or Vlad can be a plot device to create drama. For example, Danny might lose his memories of being a half - ghost, which could lead to him being confused and vulnerable. It can also be used to explore relationships, like how his friends or Vlad would react. Maybe Vlad would see it as an opportunity to manipulate Danny more easily.
Search engines can be helpful too. Google 'Danny Phantom x Vlad Plasmius fanfiction'. It might lead you to blogs or websites dedicated to collecting and reviewing such fanfictions. Also, check out the author pages of writers you already like. They might have other related works.
Don't be afraid to be creative. You can introduce new settings, like a hidden ghost realm that only Vlad and Danny can access. Also, think about the themes you want to explore, such as friendship, power, or redemption. Once you have all these elements in place, start writing and let your ideas flow.
When writing your 'Danny Phantom Bad Boy' fanfiction, it's important to create a unique plot. You could start with a situation that forces Danny into this 'bad boy' role. For example, he might be wrongly accused of something and decides to embrace the bad reputation. Develop his relationships with other characters differently. His friends might be confused or even try to change him back. And don't forget to add some action and mystery, like new ghost threats that he has to face in his new state.
Their relationship can be portrayed as a father - son dynamic. Instead of the usual enmity, Vlad could be a strict but loving father figure to baby Danny. He might scold Danny when he does something wrong with his powers, but also be there to comfort him when he's scared.
