A really interesting plotline is when the half - zombie part of Danny starts to influence his ghost side in unexpected ways. Maybe his ghostly powers become more 'undead' like, such as his ice powers now having a decay effect. This can lead to some really cool battles and interactions with other characters.
Well, I've come across a fanfiction that focuses on Danny's emotional journey as a half - zombie. In this story, Danny is not only dealing with the physical changes but also the mental ones. He has to hide his new state from his family and friends at first. It's a long and detailed story that really makes you feel for Danny as he tries to come to terms with being part - zombie.
Another plotline could involve jealousy among the members of the harem. Each character might have their own reasons for being attracted to Danny, and when they see him spending time with others in the harem, it could lead to some intense emotional moments. This can create a lot of drama and character development.
One possible interesting plotline could be Danny facing a new and more powerful ghost that has a personal vendetta against him. This would test his limits and force him to discover new powers or ways to fight.
Sure. There's a fanfiction where fem Danny travels to an alternate dimension where all the ghosts are female too. It has a really interesting take on the gender aspect of the 'Danny Phantom' world. The interactions between fem Danny and the female ghosts are both funny and full of unexpected twists.
One possible plotline could be Danny getting transported to the Naruto universe and somehow obtaining the Sharingan. He then has to learn to use it while still having his ghost powers, which could lead to some really cool battles against Naruto - universe villains.
One unique element can be the combination of the supernatural with medical settings. For example, Danny might have ghost - related ailments that normal medicine can't cure. So, they have to find ghostly remedies within the hospital. Another is the interaction between Danny and the hospital staff who might be freaked out by his powers.
One possible plotline could be Evil Danny trying to corrupt Sam. He might use his powers to manipulate situations and turn Sam against their friends. For example, he could make it seem like their friends are in danger when they're not, just to make Sam question their loyalty.
One interesting plotline could be Danny facing a new and more powerful ghost that he has to defeat to protect his town. Maybe this ghost has abilities that are completely different from what he has faced before, forcing him to develop new strategies.
One interesting plotline could be Danny learning unique ghost powers from Clockwork. Since Clockwork has control over time, Danny might gain the ability to manipulate time in some ways, like seeing into the past or future of a ghost's existence. This would add a whole new dimension to his battles and adventures.
One interesting plotline could be Danny's secret identity being revealed at school in a very unexpected way, like during a science experiment gone wrong. Maybe the ectoplasm reacts with something and his powers are exposed in front of the whole class.
